Introduction

• Laboratory crusher is also called laboratory pulverizer, also called ore sample crusher, ore sample crusher, laboratory sample crusher or laboratory sample crusher.
• Laboratory crusher equipment is mainly divided into three categories: laboratory sealed jaw crusher, laboratory sealed hammer crusher and laboratory sealed roller crusher.

• Laboratory crusher is a kind of equipment that uses the interaction of moving knife and fixed knife to crush materials into particles through cutting, impact, extrusion and other ways.

• Laboratory crushers are widely used in coal, metallurgy, mining, electric power building materials, chemical industry, medicine and scientific research departments for laboratory pulverization and sample preparation.
• The product has the advantages of stable operation, safety and reliability, long service life, few procedures, fast sample preparation, no dust pollution to the environment, simple installation and convenient use, and generally does not need screening and shrinking operation.

Principle structure

• The working principle of the laboratory crusher is to change the rotation of the motor into the high-frequency vibration of the pulverizing device supported on six springs through the action of the eccentric hammer installed at the shaft end of the motor, so that the impact block in the pulverizing chamber can impact the sample at high speed to achieve the purpose of pulverization.
• The sealed test sample preparation crusher mainly consists of a frame, a motor, an eccentric hammer, an upper cover and a pressing device, wherein the upper part of the upper cover is fixed with a pulverizing device consisting of an impact block, an impact ring and an impact seat, and the pressing device consisting of a bracket locking handle is supported on the bottom by six compression springs.
• The parts of the crushing device are made of high-quality steel, which has excellent wear resistance after precision processing.
• Under the action of impact force and compressive stress, a hard and wear-resistant surface layer can be formed, and the more times it is used, the better the work hardening and wear resistance are.
