Analysis of the types of powder making equipment

Powder making equipment is an important tool in the field of material processing that converts raw materials into powdered substances through different physical or chemical methods for various industrial applications. The following is a detailed description of the types of powder making equipment designed to provide a comprehensive and in-depth understanding.

Main Types of Powder Making Equipment

1. Mechanical Pulverizers

Mechanical pulverizers are the most common type of equipment used in powder pulverization, which breaks large pieces of material into powder by the action of mechanical forces. This type of equipment includes many types, such as hammer mill, knife mill, turbine mill and so on. Hammer mill using high-speed rotating hammer head on the material for impact and shear, suitable for a variety of hardness of the material; knife mill through the rotating blade and the relative movement of the fixed gear ring, shear and grind the material; turbine pulverizer is the use of high-speed rotating turbine blades generated by the shear force and impact to crush the material. These equipments have the advantages of simple structure, convenient operation and wide range of application.

2. Air flow pulverizer

Air flow pulverizer is another important powder making equipment, it uses high speed airflow (usually compressed air or other inert gas) impact and friction effect will be crushed materials. Air pulverizer with internal nozzles, compressed air or other media to form a high-speed air beam, these air beams in the pulverizing chamber and the material particles have a strong collision and friction, so as to achieve the effect of crushing. Air flow pulverizer has the advantages of fine particle size, high product purity, no pollution, etc., especially suitable for the powder particle size requirements of higher occasions.

3. Grinding machine

Grinding machine is through the grinding body (such as balls, rods, grinding wheels, etc.) and the relative movement between the material to realize the crushing equipment. Ball mill is a typical representative of the grinder, which uses porcelain balls or stainless steel balls as grinding media, in the cylinder body of the material for a long time rolling and grinding. Milk bowl mill, on the other hand, through the vertical grinding head of the material in the milk bowl for grinding. Mills have the advantages of uniform particle size, product fineness and so on, but usually need a longer grinding time.

4. Cryogenic pulverizer

Cryogenic mill is a special powder milling equipment, it uses low temperature environment (such as liquid nitrogen cooling) to reduce the hardness and brittleness of the material, so that it is easier to be crushed. The cryogenic pulverizer is especially suitable for those materials that are easily softened, melted or chemically reacted at high temperatures. Through cryogenic treatment, these materials can be crushed into powder while maintaining their original properties.

Summarize

There are many kinds of powder making equipment, each of which has its own unique working principle and scope of application. In the selection of powder making equipment, according to the nature of the material, crushing size requirements, production efficiency and other factors for comprehensive consideration. With the continuous development of science and technology, powder making equipment is also constantly updated, new technologies and equipment continue to emerge, bringing more possibilities and opportunities for the powder making industry.
