Jaw crushers with the simple movement of the jaw are intended for coarse crushing of granites, basalts, sandstones and other ores having compressive strength up to 300 MPa.
Jaw crushers are used in mining, pit-and-quarry industry, chemical and other industries.
Development of crushing technology is now quite simple and easy thanks to the wide product range of jaw crushers available. Technical characteristics of the available jaw crushers make it possible to use crushers on all stages of the crushing process. New models of jaw crushers with the strengthened supporting frame were designed to process the materials of high strength (with the ultimate compressive strength up to 400 MPa) and ferrochrome.
Jaw crushers ЩДП 9×12 and ЩДП 12×15 have a sectional frame that makes it possible to assemble them, using cranes of limited lifting capacity and in the space-limited environment of underground mining. These crushers can be supplied with either standard or explosion-proof electric motors.
In crushers ЩДПР 9x12 and ЩДПР 12х15 instead of a con-rod and spacing plates with crackers is used a roller that allowed to reduce weight and size characteristics at constant production characteristics.
The main features of jaw crushers are simple design, effective operation and repeatable accuracy. Different means are used to prevent the crushers from breakdown because of the ingress of some not crushable substance, such as: a friction clutch, a spacing plate with a plane of weakness or an electromagnetic clamp. In some models the safety system has an option of the crusher startup from the main drive when the processing chamber is full.
All crushers are equipped with devices for output slit width adjustment. The adjustment can be carried out quickly, the process is very safe and it does not require the crusher shutdown.
Lubrication of the crusher can be thick and liquid recirculating. Type of lubrication depends on operating conditions of the crusher.
