Powder Grinding Mill refers to the crushing machinery in which the particle size of the discharge is less than 3 mm, accounting for more than 50% of the total discharge. This type of machinery is usually classified by the size of the material size: those with a discharge size of 3 to 0.1 mm are called coarse grinding machines; those with a discharge size of 0.1 to 0.02 mm are called fine grinding machines; 0.02 mm is called micro-grinding machinery or ultra-fine grinding machinery. There are two kinds of operation methods of grinding machinery: dry method and wet method. In dry operation, the material is pulverized in the air or other gases; in wet operation, the material is pulverized in water or other liquids. Grinding machinery often works in conjunction with screening or grading machinery.
SANWEI Crushing Equipment is a professional powder mill supplier, focusing on powder mills and ultrafine mills. Our pulverizer is a new type of combined equipment. It has the advantages of novel design, compact structure, convenient maintenance, low energy consumption, high efficiency, uniform particle size, etc. The machine has a classification mechanism, which can easily separate the classification and crushing parts, which is convenient for maintenance and cleaning; the particle size can be adjusted arbitrarily without stopping.
There are five main methods for pulverizing solid materials, namely, extrusion, bending, splitting, grinding, and impact. The first four use static forces, while the last apply kinetic energy. In most grinding machines, materials are often crushed under the action of more than two crushing methods. For example, in gyratory crushers, extrusion, splitting, and bending are mainly used; in ball mills, impact and grinding are mainly used.
The grinding method is selected according to the physical properties of the material, the size of the block, and the degree of refinement required. For hard materials, extrusion, bending, and splitting should be used; for brittle materials, impact and splitting should be used; when the material block is large, splitting and bending should be used; Impact and grinding should be used instead. If the grinding method is not properly selected, there will be difficulty in grinding or excessive grinding, both of which will increase the energy consumption in the grinding process.
