working principle
   if using other types,when crushing clay, coal, shale-like substance,which would cause viscous vehicles, often plugging the machine, many factories remove adhering material on the roller by hand at regular time , resulting in machine stop.In addition, the impact crusher is not install machine protection device, when there is iron and other objects into the machine.It is likely to cause mechanical failure. And  there are a lot of powdered materials, so double roller crusher is preferred in crushing viscous material.
    The roller crusher has two opposing running and toothed roller (rotor), when the material feed in full width, two rollers would squeeze or cut the material crushing, the crushed material from the two roller discharged between two rollers. When one roller is fixed, the other is movable rollers.Movable roll bearing seat by the hydraulic cylinder with accumulator resilient positioning in the horizontal direction according to the load of the crusher, the resilient positioning clearance between the rolls can be adjusted.When a foreign object into the machine, the moving roller will concede and object discharged, while the role of mobile in the accumulator roll back to the working position, allowing the machine to be protected and to prevent motor overload.Another effect of the hydraulic unit is two roll gap adjustment to ensure product size. When you need to adjust the gap, the movable roller pump start to move the set position.
The Roll Crusher two large diameter rollers and roller axial and radial uniformly distributed 24 long tooth design is more conducive to high plasticity clay chunks cut and tear, to ensure the effective viscous materials broken.
The Roll Crusher two rollers are provided below scraping device, scraping device to tick mud several teeth are fixed to the bracket, tick mud tooth tangentially inserted between the teeth and the tooth roller, the roller rotation when, the clay can be scraped off, to prevent the material sticking roll, making the tooth surface cleaner, maintain its proper shear extrusion. After picking mud tooth wear can be adjusted to ensure that the gap tick mud between the teeth and the roller.
     Movable roll and fixed roll coupling link is used, to avoid too frequent phenomenon belt updates.
     By adjusting the gap between the two rollers crusher can freely adjust the crushing size, increase production capacity.
Product Features
     Suitable for crushing viscous material, the process is simple; fully eliminate bonding and clogging materials; easy maintenance; superior technical performance; production is safe and reliable.
     1. The distance between the roller can be adjusted to meet the needs of different discharging size.
    2. Two rollers with tooth mutually interleaved, to achieve the desired crushing action, the tooth is worn to a certain extent in order to ensure clearance between the rolls and the product fineness easily replace roll paper.
     3, It adopted special structure frame, so that the movable bearing seat can move horizontally on the slide, the bearing seat and the hydraulic cylinder with accumulator is connected, when the foreign body can not be crushed,When a foreign body can not be crushed, the machine would fall it back, the foreign body is discharged, to protect the machine from damaged.
     4, Flexible resin curtain prevents the adhesion of aqueous viscous material inside the cavity.
     5, Scraping device prevents material sticky rolls, making the tooth surface cleaner, to maintain proper cut and squeeze effect.
     6、Four main shaft can be lubricated alone, and also centralized lubrication. There are rows of bearing grease fitting, ready to discharge the waste grease, to facilitate the production and maintenance.
