Height adjustment

Figure 8: Impact roll

Crusher housing and substructure

The housing of the crusher plant and the substructure are manufactured from wear resistant material and in welded construction. The crusher housing is screwed to the substructure. Welded guidings in the pan warrant a faultless run of the chain. There is a device for a customer sided water spray system at the crusher housing (see Figure 7).

Impact roll

The impact roll is also designed in welded construction. The roll is fastened and balanced on the crusher shaft with clamping elements. The impact roll is shifting in bearing housings and spherical roller bearings. Spacing plates are available for adjusting the passage height between the roll and the conveyor. The height adjustment is by means of hydraulic cylinders which are powered either by a hydraulic pump (hand pump) or by valves. The roll height adjustment will be realized by the customer. (Find more details on the following pages and in chapter 6 - "OperationRoll height adjustment".)

Impact heads

We recommend using the following impact heads: Impact elements manufactured from wear resistant material. They are fastened to the impact roll with a thread bolt and a hexagonal nut. The impact heads can be turned and re-used when they are worn onesided.

Important! Find further instructions for work at the impact heads in chapter 6 "Operation"!

Roll height adjustment

The final product size while crushing can be varied with the height adjustment. The impact roll can be adjusted in its height by means of hydraulic cylinders. These cylinders can be pressured by a hydraulic pump or by valves. Pressure fluid is oil (customer sided face hydraulic). The roll height adjustment will be realized by the customer. Included in delivery are only the hydraulic cylinders and the fastening elements.

Important! How to adjust the height of the impact roll will be described in chapter 6 "Operation - Roll height adjustment"!

Figure 11: Roll drive Roll Drive and drift

The impact roll of the crusher plant will be driven by an electric motor with V-belt drive. The V-belt pulley of the motor is fastened to the crusher shaft with a clamping element. The roll drive is covered with a protection cover.

The belt drive of the impact roll is covered with a protection cover. For tensioning the V-belts, the drive will be moved with a hydraulical tensioning device. Important! Find more information for tensioning the V-belts in chapter 6 "Operation - Tensioning the V-belts"!

Central lubrication

The bearings of the impact roll will be supplied with grease via the central lubrication system. The bearings will be greased from the right hand and the left hand crusher side.
