Double Roll Crusher

Function

Double Roll Crusher is also called double rollsand maker. It is used for medium and fine crushing of all kinds of medium hard ore and rock in mineral separation, chemical industry, cement, building materials industrial department. The crusher consist of engine body, roller safety spring, etc. Transmission is driven by motor across belt that the rollers are rotating in two directions. Rollers space cn adjust within the prescribed limit to control the discharge size. 2PG400X250, 2PG610X400, 2PG750X500 are used as sand maker in sand making industry and for super fine crushing in particular industry. 2PG900X900 is used for medium crushing.

Operating principle

There are wedge or gasket installed between the two rollers and adjustable bolt installed on the top of the wedge device. When the adjustable bolt pulled up the wedge, the wedge will make the moved roller getting off the fixed roller.

The gap between two rollers become bigger, so does the discharge size. On the contrary, the gap become smaller, so does the discharge size. Gasket device can adjust the discharge size trhough increasing and decreasing the gasket numbers or thick and thin. When increasing the gasket, the gap between two rollers become bigger, conversely, the gap and discharge size become smaller.
