Airflow crusher

edit

The crushing mechanism that the airflow crusher is mainly suitable for determines its wide applicability and high fineness of finished products. Typical materials include superhard diamonds, silicon carbide, metal powders, etc. High purity requirements include ceramic pigments, pharmaceuticals, biochemistry, etc. Low temperature requirements include pharmaceuticals PVC。 By changing the ordinary air in the gas source section to inert gases such as nitrogen and carbon dioxide, this machine can become an inert gas protection device, suitable for the crushing and grading processing of flammable, explosive, and easily oxidizable materials.
working principle

The flow crusher, cyclone separator, dust collector, and induced draft fan form a complete crushing system. After being filtered and dried, compressed air is sprayed into the crushing chamber at high speed through a Laval nozzle. At the intersection of multiple high-pressure airflows, the material is repeatedly collided, rubbed, and sheared to be crushed. The crushed material moves to the classification zone with the upward airflow under the suction force of the fan. Under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated. The fine particles that meet the particle size requirements are collected by the cyclone separator and dust collector through the classification wheel, and the coarse particles continue to be crushed in the crushing zone.
feature

This type of crusher is suitable for large-scale chemical production and mining crushing operations;

Due to the need for strong airflow to drive material impact, the power consumption for producing airflow is quite significant;

Occupying a considerable amount of space.


Ball mill crusher

edit

The ball mill is a key equipment for crushing materials after they have been crushed. It is widely used in the production industries of cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, and glass ceramics, for dry or wet grinding of various ores and other grindable materials. Ball mills are suitable for grinding various ores and other materials, and are widely used in industries such as mineral processing, building materials, and chemical engineering. They can be divided into dry and wet grinding methods. According to different mining methods, it can be divided into two types: grid type and overflow type.

working principle

A ball mill is composed of a horizontal cylinder, a hollow shaft for feeding and discharging, and a grinding head. The cylinder is a long cylindrical body with a grinding body inside. The cylinder is made of steel plate and is fixed to the cylinder with a steel lining plate. The grinding body is generally a steel ball, which is loaded into the cylinder according to different diameters and certain proportions. The grinding body can also be made of steel sections. According to the particle size of the grinding material, it is selected. The material is loaded into the cylinder through a hollow shaft at the feeding end of the ball mill. When the ball mill cylinder rotates, the grinding material is carried away by the cylinder due to inertia, centrifugal force, and frictional force. When it is brought to a certain height, it is thrown down due to its own gravity, and the falling grinding material shatters the material inside the cylinder like a projectile.
