Post  ploor on Sun Nov 16, 2014 11:25 pm

Roll crusher or roller crusher is suitable for cement, chemical, electric power, metallurgy, building materials, refractories and other industrial sectors crushing medium hardness materials, such as limestone, slag, coke, coal, slag and other materials in the debris, crushing operations. The roller crusher consist of the roller bodies, complemented with crushing rings or crushing shells. It includes double roll crusher and toothed-roll crusher. The rolls are secured either with anchor bolts and end disks, or bolted with screws. In order to facilitate maintenance, the crushing roll shafts are arranged in heavy-duty cast steel housings with lubricated, amply dimensioned spherical roller bearings. Materials used are of highly wear-resistant specially cast alloys in order to achieve long lifetimes of parts.

Roller crusher also has the following characteristics:

1. Roll crusher features overload protection device which not only can protect the safety of the equipment, but also can protect the safety of operating personnel. Overload generally use overload block, safety pins, etc., which can effectively prevent iron and other hard objects into the roller machine, and avoid those materials damage the equipment and cause accidents.

2. Roll rings are steel castings, we usea high chromium wear-resistant impact hardfacing welding electrodes of the wear layer on the outer surface, its hardness up to HRC62, so wear roller ring, better impact resistance, pressure higher strength, and has a long-term repeated welding characteristics.

3. Most roller crushers have scraper plate and buffer device, the scraper plate having a sufficient hardness and wear resistance, the main role is to remove the roll surface skin adhesion material, and the pressing force of the scraper plate may regulation, it is also very easy to disassemble.

4. When product high-end tile, roller crushers are equipped with roller device which can timely grinding roller surface, maintaining a constant double roll gap.
