The principle and structure of roll crusher

1, the drive mechanism is driven by the two motors, through the V-belt to drive the sheave drag rollers of the crusher, and is rotated in accordance with the relative direction of movement. When crusher crushing materials, the material from the inlet through the crusher rollers to be rolled and broken, crushed product is discharged from the chassis below.

3, the series of the roll crusher is mainly composed by the roller, the roller supporting parts of the bearing, clamping and adjusting means and a drive device, etc.. For safety, the transmission portion of the crusher should be installed according to the actual situation of the safety cover.

Roll crusher Disadvantages: large area, low production efficiency. Especially in the construction materials industry, it has excellent effect generally.

The adjustment of the material size of the roll crusher: crusher between the two rollers is equipped with wedge or shim adjustment device, the top of the wedge device is equipped with the adjusting bolt. When adjustment crusher bolt wedge is pulled up, wedges takes active roller roof away from the fixed wheel, the two roller gap becomes larger, the expected size becomes larger; when crusher wedge is down, and the discharging size becomes smaller. Roll crusher spacer means by increasing or decreasing the quantity or thickness of the gasket to adjust the feed particle size, when add the crusher gasket, the gap becomes large,...
