Laboratory Jaw Crusher

Product Description

Laboratory Jaw Crusher
Working Princible
The crushing chamber of this machine consists of the casing, door, main shaft, impeller assembly, screen assembly, feed hopper, and discharge pipe, among other components. It primarily utilizes the vortex generated by the backside of the impeller blades to crush materials. During operation, the motor drives the main shaft and the impeller to rotate at high speed. Since the impeller and the teeth on the screen ring maintain a very small gap, the material entering the machine is ground again in the narrow space of the rotating airflow. In this process, the impeller sucks in a large amount of air, which cools the machine, the material being ground, and facilitates the conveyance of fine powder. Uniquely, a certain number of moving pins and static pins are added to the impeller and the door respectively, achieving pre-crushing of the material entering the crushing area. Additionally, a flat tooth ring that matches the outer side of the blade end face is added to the door to prevent coarse particles that have not been sufficiently crushed from escaping the crushing chamber. The fineness of the crushed material depends on its properties, the diameter of the screen holes, and the throughput of the material and air.
Performance & Characteristics
This machine has a compact and rational structure, stable operation, convenient installation and maintenance (no foundation required), a small footprint, large production capacity, and no dust pollution. The crushing ratio is large; typically, raw materials less than 10mm in size can be crushed with a fineness adjustable between 20-325 mesh. The device generates a large volume of air during operation, with good self-cooling capabilities, making it suitable for some heat-sensitive materials. This machine belongs to the high-speed turbine type crusher, which is highly efficient, has a large crushing capacity per unit of power, and therefore has low operating costs. The entire system is reasonably configured, and the initial investment cost is low.
Scope of Application
This machine is widely used in industries such as chemicals, dyes, pigments, paints, pesticides, food, feed, plastics, and non-metallic minerals, and is suitable for the crushing of brittle and fibrous materials with medium to low hardness.
