1. The machine has reasonable design, simple structure, fewer parts, convenient maintenance, simple operation and use. No dust leakage, stable performance, low noise, improved working environment and conditions of sample preparation, is an ideal equipment for laboratory sample preparation. It is widely used in electric power, metallurgy, chemical industry, geology and other industries. It can also be used for crushing sample preparation in other industries.
2. The feeding port of the machine is equipped with a hopper, so that no material is lost during feeding. The outlet port has a feeding hopper, and the size of the outlet is controlled by the adjusting device to adjust the width of the outlet port.
3. The structure of the whole machine is reasonable. One-stage crushing replaces multi-stage crushing. It has reliable performance, convenient adjustment, stable operation, low vibration, low noise and less dust.

Jaw crusher is used to crush coal, gangue, coke, limestone, pyrite and other materials in laboratory. The crushing mode is extrusion crushing, and the purpose of crushing material is achieved by two teeth jaw plates. It can crush all kinds of brittle materials with strength less than 250 Mpa in coarse, medium and fine grains. The machine has the characteristics of large crushing ratio, uniform particle size, convenient adjustment, less fully sealed dust and so on.
