Stone Double Roller Crusher

Product Description

Stone Double Roller Crusher

      The roll crusher is applied in the industry of cement, chemical, electric power, metallurgy, building materials, refractories 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 pisolite and greenbean shake production.

 Working principle and structure of the roll crusher

     1. this series of roll crusher is mainly formed by the roller, roller support bearing, compression and adjusting device, drive components etc.
     2. 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. 
     3.  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.
      4.  for safety, drive part should install the security cover according to the actual situation respectively.  Stone Double Roller Crusher Technical parameters
