From the perspective of structural details, the powder metallurgy ultrafine pulverizer adopts an integrated design, integrating the four functions of feeding, crushing, grading, and collection together without the need for additional auxiliary equipment. This can significantly save workshop space, simplify production processes, and improve processing efficiency. All core components of the equipment are made of high hardness wear-resistant alloy materials. The grinding chamber lining plate, grinding hammer, grinding roller and other easily worn parts have undergone special quenching treatment, which can effectively resist the friction loss of hard metal powder, significantly extend the service life of the equipment, and reduce maintenance costs in the later stage. The feeding system is equipped with a variable frequency speed control device, which can flexibly adjust the feeding speed according to the hardness of the material and the actual crushing needs, avoiding problems such as blockage of the crushing chamber and uneven feeding, and ensuring the continuous and stable operation of the equipment.

In addition, the powder metallurgy ultrafine pulverizer adopts a fully enclosed negative pressure structure, combined with imported sealing rings, which completely solves the old problems of air leakage and powder leakage in traditional crushing equipment. It can not only protect the production environment and avoid dust pollution that endangers the health of operators, but also prevent external impurities from mixing into the powder, ensuring that the purity of the finished powder meets the standard. The device operation panel is designed to be very user-friendly, with functions such as one click start stop, parameter adjustment, and fault alarm clearly visible. Without the need for professional technical training, ordinary operators can quickly get started, greatly reducing labor costs.

Manufacturing Principle

The core working principle of the powder metallurgy ultrafine pulverizer is to gradually crush coarse powder raw materials into ultrafine powder that meets the requirements of powder metallurgy production through the synergistic effect of high-speed impact, shear, and friction. The entire processing process is carried out in a closed negative pressure environment, which is both environmentally friendly and ensures processing accuracy.

The specific processing flow is simple: first, feed the coarse powder raw material with a particle size of no more than 10mm into the feeding hopper, and then transport it to the crushing chamber at a constant speed through a variable frequency feeder; The grinding disc in the grinding chamber rotates at high speed, driving the grinding hammer and grinding roller to run synchronously at high speed, generating strong centrifugal force, and throwing the coarse powder raw material into the inner wall of the grinding chamber; Under the action of centrifugal force, raw materials undergo severe collisions, shearing, and friction with wear-resistant lining plates, crushing hammers, and crushing rollers, completing preliminary crushing; After initial crushing, the material will be brought into the classification chamber by the negative pressure airflow generated by the induced draft fan. The classification wheel in the classification chamber rotates at high speed to accurately classify according to the particle size. The ultra-fine powder that meets the requirements (particle size can be adjusted as needed) will be brought into the collector by the airflow to complete the collection; Coarse powder that does not meet the particle size requirements will be intercepted by the grading wheel and sent back to the crushing chamber for secondary crushing until it reaches the specified particle size standard, ensuring the uniformity of the finished powder.
