Primary crusher overview 
Both crushed stone production line and mechanism of sand production line equipment, the primary crusher is a kind of crusher equipment is needed. In the primary crusher, jaw crusher is the most used more primary crusher equipment, jaw crusher can be coarse, broken compressive strength less than 350 mpa in various ore rock material, such as granite, basalt, limestone, etc.

Primary crusher – jaw crusher great advantages
1. The primary jaw crusher have depth crushing cavity and no dead zone to improve the ability to feed and production;
2. The crusher ratio is big, product size uniform,
3. The gasket type discharging mouth adjusting device, convenient and reliable, the adjusting range is big to increase the flexibility of stone primary crusher;
4. Safe and reliable lubrication system, parts easy to change, primary crusher equipment maintenance is simple;
5. Simple structure, reliable operation, low operating costs.
6. Equipment and energy saving: stand-alone energy saving 15% ~ 30%, and the system energy saving more than double;
7. Low noise, little dust.
Primary crusher – jaw crusher working principle 
DSMAC can manufacture the primary crushers including jaw crusher, motor drive belt and pulley, make through eccentric shaft dynamic jaw movement up and down, when moving jaw rising bracket and dynamic Angle between hubei, pushing dynamic jaw plate to the fixed jaw close, at the same time the material being extrusion, rolling multiple crushing, grinding, etc. When the moving jaw downward, bracket and dynamic jaw Angle between smaller, under the action of moving jaw in a bar, spring away from fixed jaw plate, now broken material from crushing cavity mouth education, as the motor turns continuously broken mobile jaw for periodic crushing and discharging, realize batch production.
