Excellent Quality Low price rock, stone double roll crusher

Roll crushers have the advantage of producing an end-product that is has a fine size distribution

and they produce little dust or fines during operation. They are widely used for crushing minerals whose

abrasive levels are low and in the small scale production of mine. Roll crushers are mostly used during

coal mining. The crushers used may either be single roll or double roll. When used in coal mining, the

surface of the rolls will have teeth or raised forms (when used for mineral and metal ores, the rolls

have a smooth surface).

The roll crushers are capable of producing between 100 and 120 million bricks per year. They are

widelyused in the production of facing bricks, paving bricks, hollow and thermal bricks.

Adjustable output granularity: There are wedge-shaped or gasket regulating device between

the two rollers, the top of wedge-shaped device is adjustment bolt. The wedge tips active roller away

from the fixed wheel when adjustment bolt pulls wedge upward. At this time, up, wedge will the space

between the two rollers becomes larger, output granularity becomes larger. When the wedge is down,

the gap of the two active rollers becomes smaller under the action of the compressing spring, particle

size becomes smaller. Gasket regulating device adjusts the size of particle through increasing or

decreasing the quantity or thickness of pads. The gap of two rollers becomes large when increasing

gasket. The gap of the two rollers becomes smaller when reducing gasket output granularity becomes

smaller.
