HSI crushers many advantages:

Advanced technical level which increases the affectivity of the operation

High degree of comminuting, can be enhanced by incorporation an extra crushing route

Variable construction of the box to incorporate the HIC crusher into stationary lines or mobile equipment

Enclosed rotor body, fixed attachment of crushing bars in rotor Compact solution of flexible units, impact plates and crushing plate slot adjustment An easy access of operator during maintenance due to hydraulic opening of the crusher body

High quality= highly range of HIC crusher application

Variable design wide range of HSI crusher application :

There is a wide range of application of HIC crushers due to variability of their design. The equipment can be adjusted to either stationary or mobile application by changing the location of the feeding hopper. The mobile adjustment complies with the requirements for the minimum height of the feeder and protection against shooting of the aggregate out off the internal space of crusher.

The extra accessories, the crushing route, of the HIC crusher increase the crushing effect and the combination of the crusher material. The name of the crusher with the crushing plate includes mark

The HIC crusher can be adjusted to crush materials with higher abrasion. The HIC crusher, which crushers abrasive material, includes A in its name.

We are Leading Manufacturer and supplier of Conveyor System for Crushing Plant.

The roller crusher are used for fine crushing of wide variety of materials. The advantage of this kind of crushing is a significant reduction of occurrence of fine dust particles in the final product.

ROLL CRUSHERS

FORCES INVOLVED IN SIZE REDUCTION ARE IMPACT, COMPRESSION, ATTRITION AND SHEARING. LAWS INVOLVED IN SIZE REDUCTION ARE RITTENEGERS LAW , KICKS LAW AND BONDS LAW . SIZE REDUCTION INVOLVES REDUCING THE SIZE OF PARTICLES SO AS TO GET MORE PRODUCTS. SIZE REDUCTION

The reduction ratio is the ratio of crusher feed size to product size. As stone passes through a crusher, the reduction in size may be expressed as reduction ratio. The degree of breakage is spread over several stages as a means of closely controlling product size and limiting waste material. The output of the primary crusher is fed to a secondary crusher, which further reduces the stone size. A primary crusher receives the stone directly from a quarry after blasting, and produces the first reduction in size. Crushers are classified according to the stage of crushing which they accomplish, such as: Primary, Secondary, Tertiary TYPES OF CRUSHERS

Roll crushers have a theoretical Maximum reduction ratio particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch. Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm). A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rollsu Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. ROLL Crusher

Coal is probably the largest user of roll crushers currently though. Coal plants will use roll crushers either single roll or double roll as primary crushers, reducing the ROM coal. 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. Some major advantages of roll crushers are they give a very fine product size distribution and they produce very little dust or fines. 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. 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.

Working Principle and Structure of Double Roller Crusher :-

This series of roll crusher is mainly formed by the roller, roller support bearing, compression and adjusting device, drive components etc.

The adjustment of the particle size: between the two rollers equipped with adjustment device like pads or wedge .The wedge-shaped device has a adjusting bolt on top, when the adjustment bolt pull up the wedge, the wedge will push the movable roller away from the fixed roller , then the gap between two rollers is larger and produce larger particle size. When the wedge falls down, with the effect of the compression springs, the movable roller makes the gap become smaller between two rollers and thus produce the smaller particle size. Pad device can adjust the output size by changing the quantity of the pads or its thickness, Adding more pads, larger gap between two rollers, and when reducing the pads, it comes the smaller gap and smaller output size. DOUBLE ROLL CRUSHER

Application of Double Roller Crusher

The double roll crusher is applied in the industry of cement, chemical, electric power, metallurgy, building materials, refractoriness and other sectors for crushing medium hard materials such as medium and fine crushing of limestone, slag, coke, coal and other materials. It is more superior than ordinary crushers especially in the construction Materials Industry like isolate and green bean shake production. Drive device is composed of two electric motors. V-belt drags the rollers through drive of the grooved pulley move and rotate in the relative direction. In the crushing, the materials enter the feed opening and through the rollers, rolled and grinded, the finished products will discharge from under the chassis. For safety, drive part should install the security cover according to the actual situation respectively.

SMOOTH ROLL CRUSHERS :-

SUITABLE FOR FRIABLE AND BRITTLE MATERIALS LIKE COAL, SOFT LIMESTONE, SLAG, CLAY ETC THEY OPERATE BY COMPRESSION, IMPACT AND SHEAR AND SO IT CAN REDUCE MUCH LARGER PARTICLES THEY ARE MORE VERSATILE THAN SMOOTH ROLL CRUSHER BUT CANNOT HANDLE VERY HARD SOLIDS CONTAIN 1 OR 2 CURVED ROLL WORKING AGAINST A STATIONARY CURVED BEAKER PLATE TOOTHED

ROLL CRUSHER

The extent to which the stone is fed uniformly into the crusher. The speed at which the rolls rotate The width of rolls The size of the finished product. The size of feed The kind of stone capacity of roll crusher. The capacity of a roll crusher will vary with:

POWER CONSUMPTION OF ROLL CRUSHERS WITHIN THE SAME REDUCTION RATIO POWER CONSUMPTION OF ROLL CRUSHER VARY WIDELY THE POWER REQUIRED COULD BE GIVEN BY GENERAL EQUATION.

ANGLE OF NIP

IF CRUSHING ROLLS, 1M IN DIAMETER ARE SET SO THAT THE CRUSHING SURFACES ARE 12.5mm APART AND THE ANGLE OF NIP IS 31.WHAT IS THE MAXIMUM SIZE OF PARTICLES THAT SHOULD BE FED TO THE ROLLS PROBLEM QUESTION

Crushers many advantages:

High technical level focusing on operation and maintenance

Minimum dust particles in the product

The rotor design makes the exchange of worn bandages easier

The Vibro feeders are used for discharging , per-screening and feeding of an even volume of non- sticking , bulk materials form a hopper or a soil into the crusher , grinding plant or screening equipment , converging transportation etc.

The per-screening of the material takes place on a installed screening grate with the size up to 150m.m.

The feeder is driven by two attached vibrating motor. To change the feeding amount, adjust the unbalanced weights of the vibrating motor or change the frequency by the frequency converter.

vibration feeder many advantages :

Resistance against clogging and sticking of the screened material on the screening grate

The cascade design of the grate deck makes the screening of finer fraction more effective

Minimum operation costs, which results form the balanced machine design, utilization of many years of vibration feeder operation experience and unification of parts.

Easy exchange of the armoring

High quality=High affectivity + High economic operation.
