Pin Grinding Crusher

What is Pin Grinding Crusher?

Pin Grinding Crusher adopts the principle of high-speed impact and shearing compound, and realizes ultra-fine grinding of materials through a precisely designed rotor and stator needle bar system. The material is transported to the grinding chamber by the feeding system, and is subjected to repeated impact, shearing and grinding between the high-speed rotating rotor needle bar (speed can reach 250m/s) and the fixed gear ring, and finally discharged through the precision screen to obtain uniform ultra-fine powder.

Compared with traditional grinding equipment, our Pin Grinding Crusher has the following unique working characteristics:

Fully enclosed negative pressure system: patented vacuum environment operation (0/20ATEX certification), completely exclude oxygen, eliminate explosion risks, especially suitable for flammable and explosive material processing

Low temperature crushing technology: extremely low friction heat, no liquid nitrogen cooling, process temperature rise is controlled below 50℃, perfectly protect heat-sensitive components

Self-cleaning design: special rotor structure avoids material accumulation, with quick-release pipe connection, to achieve fast material change and cleaning

What types of Pin Grinding Crusher are there?

Pin Grinding Crusher can be divided into standard type, ultra-fine type, low-temperature type, and explosion-proof type according to different processing capabilities, discharge fineness requirements and application fields.

Standard Pin Grinding Crusher: It has strong versatility and is suitable for fine grinding of a variety of medium-hard materials.

Ultra-fine Pin Grinding Crusher: It adopts more precise grinding elements and higher rotation speed to achieve ultra-fine grinding of micron or even sub-micron level.

Low-temperature Pin Grinding Crusher: It is equipped with a cooling system to effectively control the temperature rise during the grinding process and is suitable for the crushing of temperature-sensitive materials.

Explosion-proof Pin Grinding Crusher: It adopts a special explosion-proof design to meet the crushing needs of flammable and explosive materials to ensure production safety.

What are the advantages of Pin Grinding Crusher?

High crushing efficiency: The particle size distribution is precisely controlled, the PSD range is as low as D90<6μm, the processing capacity is as high as 1000 kg per hour, the energy consumption is reduced by more than 30%, and no additional cyclone separator is required.

Narrow particle size distribution: By precisely controlling the grinding gap and rotation speed, powders with uniform particle size distribution and controllable fineness can be obtained.

Wide range of applications: It can handle a variety of materials of different properties, including chemicals, medicines, foods, minerals, feeds, etc.

Easy operation and maintenance: The structural design is reasonable, easy to install, operate, clean and maintain, and reduces labor costs.

How does Pin Grinding Crusher work?

The working principle of our Needle-Type Grinding Mill is based on the high-speed rotation of a set of needles. As the material enters the grinding chamber, it is subjected to intense impact and shearing forces from the rapidly rotating needles. This continuous action breaks down the material into fine particles, which are then discharged through a sieve or cyclone separator.

What are the applications of Pin Grinding Crusher?
