Apron Feeders

The Apron Feeder consists of one or more endless chains to which overlapping pans are attached to form a continuous moving bed particularly suited for conveying heavy duty raw materials such as coal, coke, ore, slag, rock, stone, gravel, clay, etc. They are frequently used as feeders located under crushers and hoppers. Apron Feeders can be installed in horizontal and inclined condition depending on the feeding zone of system layout. It is recommended that for higher conveying efficiency, the feeder’s inclination should be within 10 degrees. Its use lends itself to situation where a belt conveyor is not suitable i.e., for hot materials and large material lumps.

Vibrating Grizzly Feeders

The vibrating grizzly is used to separate ROM feed material into fractions prior to the primary crushing stage of the process. It is used in both large stationary plants and mobile crushing plants. We have the feeder for your application. These feeders utilize high strength steels and high stroke vibrators to produce a high production to weight ratio for portable operations. Heavy duty feeders are designed for stationary plants with their massive frames and high output vibrator mechanisms.

RECIPROCATING FEEDER

Reciprocating feeder is mainly used for feeding various non-sticky materials. The reciprocating feeder can send massive and granular materials from feed bin to receiving device evenly and continuously. The reciprocating feeder has been widely used in the crushing and screening line of the industries of thermal power plants, beneficiation, sponge iron, cement and chemical industries etc.

Wobbler Feeders

Wobbler Feeders provide two functions – feeding oversized material at a controlled rate and scalping out the fines from the feed material. These can be used to accomplish feeding and scalping for industries such as coal, salt, gypsum, phosphate, limestone, bauxite, coke, quartz, granite, aggregate and other mineral processing applications. They are especially good with wet, sticky material with high percentages of clay.

A jaw crusher is generally used as a primary crusher in a crushing circuit. Product is fed into the top of the jaw crusher. The eccentric rotating drive shaft causes the movable jaw to oscillate crushing the aggregate against a fixed jaw. Jaw crushers are run on belt drives driven by an electric motor or diesel engine. Jaw crushers are used extensively throughout the aggregate and mineral processing industry.

SINGLE TOGGLE JAW CRUSHER

• Single Toggle Jaw Crusher Used for primary crushing of a wide Variety of Materials in Mining, Iron and Steel As well As Pit and Quarry Industries.
• Single toggle jaw crusher has shaft and bearings and only one toggle which go from bottom of swinging jaw to a fixed point at back of jaw crusher.
• The eccentric shaft is located at the top of swinging jaw and is part of shaft.
• Single toggle jaw crushers are provided in heavy and light versions with welded steel housing and a moving jaw in a welded or cast steel version, as well as an eccentric shaft made of high-grade forged steel.
• The Material Ranging from Medium Hard to Extreme Hard.

DOUBLE TOGGLE JAW CRUSHER

• Double Toggle Jaw Crushers are preferred for crushing usually hard, abrasive rocks and other materials like ferroalloys and glass. They differ substantially from other types of crushers. There is no rotary motion in the crushing cycle and all crushing is done by compression of the feed material between two massive jaws plates. The moving jaw compresses the material against the stationary jaw. Jaw plates can be either smooth or corrugated.
• Double Toggle Jaw Crushers have one jaw fixed, while the other pivots about a top hinge. This moving jaw is shaped to move firmly and squarely against the material. There is no rubbing or grinding. Only compression, which produces a generally cubical product with minimum fines.
• The moving jaw is very well balanced, so 95% of the drive motor power is used for crushing. While only 5% of the power is needed to move the jaw itself.
• As a result of this high mechanical efficiency, double Toggle Jaw Crushers require smaller size motors, keeping power costs down. Behind the stationary jaw are shims, used to adjust the distance between the lower ends of the jaws (closed side setting). The setting determines the output product size.
• There is also an arrangement of safety arm for protection from us-crushable accidental overloads

SINGLE TOOTHED ROLL CRUSHER

• The single toothed roll crusher is actually a rotary roller which consists of a large tooth and also a crushing plate which is adjustable according to the need and requirement.
• The material that is fed into the single roll crusher is smashed first and then pressed from inside of the single tooth roll breaker followed by passing it through the braking cavity after which the rotary roller shifts it to the space amidst the tooth roller and the crushing plate which break the material into desired shapes.
• It’s used for wet and sticky material.

DOUBLE ROLL CRUSHERS

SMOOTH DOUBLE ROLL CRUSHER

• It is used for primary and secondary crushing of soft and medium hard as well as sticky and wet material.
• A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product.
• The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle.
• The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls.
• Major advantages of roll crushers are they give a very fine product size distribution and they produce very little dust or fines.
• Rolls crushers are effectively used in minerals crushing where the ores are not too abrasive and they are also used in smaller scale production mining of more abrasive metal ores, such as gold. Coal industry is probably the largest user of roll crushers.

TOOTHED DOUBLE ROLL CRUSHER

• Double roll crusher has big reduction ratio, without any requirement on the material moisture, no adhesion or blocking, less over crushed materials, low noise, small vibration, low dust, low energy consumption, small footprint, simple and convenient maintenance, etc.
• Double teeth roll crusher is equipped with hydraulic automatic concession device, which can effectively prevent damage of iron to roll and hazards of wood and flexible objects to the normal work of rollers.
• The toothed roll crusher adopts mechanical, electrical, hydraulic and other safety devices and systems, which effectively protects the motor, crushers and the entire system.
• The double toothed roll crusher with high efficiency, energy saving, environmental protection and other benefits have replaced the imported crushing equipment and become the preferred devices in thermal power plants, which are suitable for the crushing of medium and low hardness brittle materials, like bituminous coal, anthracite, lignite and coal waste, which also can be used for sinter, coke, slag, limestone.

FOUR ROLL CRUSHER

• Four roll crusher is fixed with four high-strength resistant alloy grinding rolls.
• Their relative rotation generates high extrusion pressure and shear force for crushing the material.
• Firstly the material enters into the space between the topside two rolls. Here, it is extruded, rolled and sheared (thick broken) because of the rotation of the topside two rolls.
• Then, it is secondly extruded and gnawingly milled (fine crushing) by the middle two rolls which are relatively rotating.
• Finally, under the extrusion, cut and mill of the next two rolls, the material becomes the required size.

HORIZONTAL SHAFT IMPACTOR

• Horizontal Shaft Impact crusher is widely used for sand and rock producing in the industry of roads, railways, reservoir, electricity power and building materials and so on with cubical shape.
• Impact crushers can produce cubic products with very good grain shape, adopting the latest manufacturing technology and unique structure design.
• Horizontal Shaft Impact crusher use impact energy to crush materials. Driven by the motor, the rotor revolves at a high speed. Revolving blow bars in the rotor blow the materials.
• Then the materials will be thrown to the impact plates for secondary crushing. The materials will be shot back to the blow bars again.
• This process repeats until the materials are crushed to the required size and discharged through the discharging opening at the bottom of the machine.

VERTICAL SHAFT IMPACTOR

• In VSI crusher the material fed in from the central opening. And in VSI they converted into small size as cubic shape.
• VSI works on high rpm with high reduction ratio. VSI has reduces dusting and improves cubicness
• We can us optimized rotor structure that reduces the wear and tear of rotor
• Lower operating and maintenance cost because of reduction of wearing &tearing of parts

A hammer mill is a crusher that can grind, pulverize, and crush a wide range of materials. This rock crusher machine employs a rain of hammer blows to shatter and disintegrate the material. Hammer mills produce a finish product size that is dependent upon...

• Openings in perforated screens or grate bars
• Number, size and type of hammers
• Grinding plate setting
• Rotor speed

Hammer mill is mainly used for hard coal and lignite in coal processing plant, coking coal for the iron and steel industry and for soft to medium hard material

A cone crusher is generally used as a secondary crusher in a crushing circuit. Pre-crushed product (usually 3in minus depending on the cone crusher model) is fed through the top of the cone crusher and flows over the mantle. The vertical cone crusher drive shaft rotates the mantle eccentrically below the concave, or bowl liner, squeezing the product and crushing it between the mantle and concave. Cone crushers are usually run on belt drives driven by an electric motor. Cone crushers are used extensively throughout the aggregate and mineral processing industry. The optimized structure and cavity adapting inter-particle crushing principle ensure high performance of crusher.

It improves the efficiency and decreases wear of wear resistance parts and improves quality of final product.

Disintegrators are well designed hammer mills of simple and sturdy construction.

They are ideally suited where coarse grinding of soft and medium hard minerals products is required. The main shaft is the only revolving parts, which require no adjustment. This main shaft runs on Ball/Roller bearings and it contains fix/swing type hammers. All portions of the body where wear and abrasion is expected are lined with replaceable hard alloy liners. The grinding is achieved by the impact of hammers against the liner fitted in the body.

Linear Motion Vibrating Screens

• The linear motion screens are horizontal/low inclination Screens and its operation is based on the micro throw principle. The operating frequency is generally 750 or 1000 vibrations per minute and easily adapted to the material to be screened in terms of angle of throw and amplitude which are adjustable within certain limits. Great stress has been laid on machine ruggedness and stability, simple maintenance and servicing including replacement of screen decks. Depending on application the machines are available as single or double deck type. Drive is from standard AC motor via cardan shaft.

• Design feature wear-resistant screen plate is made of alloy heatproof steel or chromium steel a drive is of self-synchronizing type from two independent kinematic electric motors the electric motor torque is transferred to the vibration driver shafts via a propeller shaft a lubrication unit with heat exchanger ensures lubrication and cooling of the vibration driver bearings the electric circuit of the drive incorporates electrical braking to decrease the screen oscillation amplitude in stop and, hence, to reduce the foundation loads the screen is placed on the roll-away trolley to simplify its maintenance

HOT PALLET SCREEN

• The hot pallet screen is used for sorting of hot fired pellets, ores and the like. Design feature wear-resistant screen plate is made of alloy heatproof steel or chromium steel a drive is of self-synchronizing type from two independent kinematic electric motors the electric motor torque is transferred to the vibration driver shafts via a propeller shaft a lubrication unit with heat exchanger ensures lubrication and cooling of the vibration driver bearings the electric circuit of the drive incorporates electrical braking to decrease the screen oscillation 2amplitude in stop and, hence, to reduce the foundation loads the screen is placed on the roll-away trolley to simplify its maintenance

BANANA SCREEN

• The Banana Screen benefits from utilising linear motion combined with high vibration amplitude and high acceleration over the screen deck. This makes the Banana Screen suitable for a variety of applications. These combined features also reduce the possibility of blinding and pegging.

The Benefits of Multi Angle Screening are

• Improved efficiency in sizing material due to formation of a thin bed depth.
• Lower water consumption, with wet screening.
• Lower energy requirement, for an equivalent throughput on a conventional flat deck screen.
• Higher feed rates for an equivalent deck area.

ALL SCREENS ARE IN FULLY DUST COVER, SEMI DUST COVER & WITHOUT DUST COVER.

Circular Motion Vibrating Screens

• Circular motion screens are inexpensive (economic) screening machines, where the whole screening unit is excited to circular oscillations. The oscillations of this screening machine are generated via an unbalance shaft which runs in spherical roller bearings and which have in addition outside right and left arranged swing weights, adjustable during standstill. With these weights, the oscillation amplitude can be adjusted to the product requirements.
• ALL SCREENS ARE IN FULLY DUST COVER, SEMI DUST COVER & WITHOUT DUST COVER.

Resonance Motion Screens

• The Resonance motion screens employ the principle of resonance and dynamic vibration adsorption for the screening. These screens make a suitable choice for pre-classification and sizing of Run of Mine materials. Grading can be done on coarse and intermediate grain sizes. By using different sieves or bar rusts (grizzly) and different drive configurations, the resonance screens can be adapted to the respective screening or feeding requirements.

Elliptical motion vibrating screen

• Elliptical motion vibrating screens are driven by two centric main shafts, which generate a swing diameter as in a free running drive. Another synchronized shaft transforms the swing diameter into an ellipse defined by its task. The second shaft distorts the swing diameter into an ellipse. The big advantage of these machines is that they can work with a very low inclination or with no inclination at all.
• Both shaft drives are controlled by a frequency converter based on the master-slave-principle. The elliptical motion vibrating screen is freely adjustable from 0 to 90°at the plant visualization or through an external potentiometer. Dropping angle and speedup can thus be altered while the screen is operating.

FLIP FLOW SCREEN.

• Flip-Flow Vibrating Screens remove fines out of wet, sticky or generally difficult to handle materials. Materials processed using a Flip-Flow Vibrating Screen typically cannot be screened using other technologies, such as rotary screens, conventional vibrating screens, etc. Flip-Flow Vibrating Screens utilize elastic mesh screens made from polyurethane.
• Screens are made of high density polyurethane panels. Panels are mounted in separate sections with screen sizes, depending on the product being screened and mesh opening needed. Each panel is fixed to both the main frame and the sub-resonant frame. By amplifying the vibration of the main frame of the screen in the sub-resonant frame and due to the polyurethane panels being fixed to both frames, screen panels bump together creating the “flip-flow” motion. This ensures that screened material will not stick or get caught in the screen.

Trommel Screens

• A trommel screen is named for the screened cylinder used to separate materials by size, for example, separating the biodegradable fraction of mixed municipal waste or separating different sizes of mulch or crushed stone. The trommel screen comprises the rubber-lined steel frame and replaceable screening surface. Several modifications can be made to this basic trommel screen, including a dual media screen to produce a two-fraction material grading, as well as hydraulic or mechanical self-propulsion.

SHALE SHAKER

• The primary and probably most important device on the rig for removing drilled from the mud. This vibrating sieve is simple in concept, but a bit more complicated to use efficiently. A wire-cloth screen vibrates while the drilling fluid flows on top of it. The liquid phase of the mud and solids smaller than the wire mesh pass through the screen, while larger solids are retained on the screen and eventually fall off the back of the device and are discarded. Obviously, smaller openings in the screen clean more solids from the whole mud, but there is a corresponding decrease in flow rate per unit area of wire cloth.

Twin-and Three-Tube Vibrating Mills are driven by an unbalanced drive. The entire filling of the grinding cylinders, which comprises the grinding media and the feed material, constantly receives impulses from the circular vibrations in the body of the mill. The grinding action itself is produced by the rotation of the grinding media in opposite direction towards the driving rotation and by continuous head-on collisions of the grinding media. The residence time of the material contained in the grinding cylinders is determined by the quantity of the flowing feed material. The residence time can also be influenced by using damming cylinders in a helical curve and slides down from the inflow to the outflow. The high degree of fineness achieved is the result of this long grinding procedure.

A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill.

Both dry and wet types are available.

The continuous lifting and dropping action in rotary scrubber helps abrade, scrub and breakdown soluble contaminates in the feed material. Rotary Scrubbers can handle large feed sizes and high tonnages in comparison to other types of washing equipment. As an added benefit, they are lower in operating and maintenance costs. Minus 1/4" (6mm) material should be removed prior to Scrubbers in order to achieve an aggressive washing action on the coarse rock. This can be done with conventional screens ahead of the Scrubber or through a built-in desander section. If Sand Equivalency (SE) needs to be improved, then the fines can be left in the feed and coarse rock will wash the finer material.

Both dry and wet types are available.
