Laboratory Applications

Star Trace Laboratory Jaw Crusher is mainly used for a variety of rocks or ores with medium hardness , which is the most important laboratory equipments in metallurgy, geology, building material, chemical industry. The suitable materials are pyrite stone, limestone, basalt, rock phosphate, barite, Alloys, Coal & coke, etc.


The machine structure of lab jaw crusher
This series of jaw crusher is composed of machine body, eccentric shaft, belt pulley, fly wheel, movable jaw, side guard, gap adjustment screw, return spring, fixed jaw plate and movable jaw plate. This series of crusher have: high crushing ratio, regular finished product size, simple structure, reliable operation, easy to maintain and other characteristics.

Lab Jaw Crusher Operating Principle
For this crusher, crushing way is squeeze-press type, motor drive belt and belt pulley , through eccentric shaft to make movable jaw move up and down. When the movable jaw rises, the angle between toggle plate and movable jaw plate will become large, so that moving the movable jaw plate closed to the fixed jaw plate, meanwhile the material is pressed, rubbed, grinded for many times; When the movable jaw plate down, the angle between toggle plate and the movable jaw plate will become small, with the effect of spring, the movable jaw plate will leave fixed jaw plate, at this time, the crushed material has be discharged out from the crushing chamber. With the motor continuous rotation, the movable jaw plate will make a periodic crushing and discharging to realize continuous crushing.
