Lab Mini Jaw Crusher

Lab mini Jaw crusher Applications:

1. Overview of laboratory jaw crusher

Laboratory jaw crusher (jaw crusher for short) is mainly used for medium-sized crushing of various ores and bulk materials. It can crush materials with a compressive strength of no more than 320Mpa. It is divided into two types: coarse crushing and fine crushing. The PE series jaw crusher has complete specifications and its feeding particle size ranges from 125mm to 1200mm. It is a primary powder crushing equipment. This equipment is mainly used for coarse, medium and fine crushing of limestone, calcium carbide, calcium carbide slag, shale, basalt, river pebbles, bluestone and other ores. It is used in cement plants, sand and gravel plants, stone factories, thermal power plants for desulfurization and calcium carbide plants. The effect is very good and it is widely used in mining, metallurgy, chemical industry, building materials, water conservancy, transportation and other industries.

2. Working principle of laboratory jaw crusher

The main structure of laboratory jaw crusher: frame, eccentric shaft, large pulley, flywheel, side guard plate, toggle plate, toggle plate rear seat, gap adjustment screw, return spring, fixed jaw plate and movable jaw plate, etc., among which The toggle plate also serves as insurance. The crushing method of this series of jaw crushers is curved extrusion type. The motor drives the belt and pulley, and moves the movable jaw up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, thus pushing the movable jaw plate closer to the fixed jaw plate. At the same time, the material is squeezed, Rubbing, grinding and other multiple crushing. When the movable jaw moves downward, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and spring. At this time, the crushed material is discharged from the lower opening of the crushing chamber. As the motor continuously rotates, the movable jaw plate of the crusher performs periodic crushing and discharging to achieve mass production.

3. Performance characteristics of Tianchuang powder laboratory jaw crusher

1. The crushing ratio is as high as about 15 and the particle size is uniform;
2. The gasket-type discharge port adjustment device has a large adjustment range and reliable operation;
3. High production efficiency and low energy consumption. Compared with ordinary fine jaw crushers, the processing capacity is increased by 20-35% and the energy consumption is reduced by 15-20% compared with the same specifications;
4. The crushing cavity is deep and has no dead space, which improves the feeding capacity and output;
5. The hyperboloid jaw plate has less wear. Under the same process conditions, the life of the jaw plate can be extended by more than 3-4 times, which is more obvious for highly abrasive materials;
6. The lubrication system is safe and reliable, parts replacement is easy, and the maintenance workload is small.
