Roller crusher machine seat usually cast iron base, but also cast or rolled steel welding machine seat should be installed to maintain the level of the base, due to the strength and stiffness of the chassis, do not re-use statistics hammers hammering stand.Roll crusher roller bearing at generally used the train axlebox type sliding bearing, and therefore, when installed, in axlebox opening a horizontal inclination of 30 to 45 · mouth, in order to install a removable cover, so that the replacement of bearings when convenient.
Install roller slip, should be careful alignment center, and to make the power balance test, otherwise the rolls in the operation is necessary to "beat" and quickly destroyed the entire machine.
Toothed roller there are three: the first with a hard carbon steel wrought or stamped teeth inlaid and fixed on the rollers, such as with a wedge fixed, this cog unreliable, and also very difficult to repair disassembly. Entire roller is composed of several with manganese steel and tooth cast one single ring, this just allows only the replacement of wear ring up to the most powerful aspect is the the reasonable general wear most powerful ring roller the total length of the central third of each ring, wear lighter ring still put something on both sides in order to continue to use. Third, on the cast iron hub in two or three, are equipped with separate steel plate with manganese steel and the teeth molded integrally formed by a combination of the cylindrical roll shell, and this was more widely used.
The shape of the teeth is a variety of the most simple tooth is shaped neyzeh. Teeth mounted on the rollers, it is best to make the teeth of the cutting blade instead of a flat forward movement, that is, the teeth cleave be crushed rock instead of crushing the rock; which can not only save power, but also to reduce the fault and the risk of damage. Only in a single-roll stone crusher for crushing brittle rock, be allowed to violate this rule, because in such a crusher crushing brittle material, except that the chipping, the striking movement of the teeth have a very a large role.
