Several types of feed grinders

Feed grinder is a kind of equipment mainly used for crushing feed raw materials and various roughages. The size of its crushing particle size has an important influence on the subsequent process and the quality of the finished product. Feed grinder is mainly composed of high-speed rotating hammer, screen plate and fan. The high-speed rotating hammer is the main crushing component, which crushes feed raw materials and roughage into fine particles through high-speed rotation. The screen plate is used to control the size of the crushed particles, and the fan is used to discharge the crushed particles.

When using the feed grinder, it is necessary to pay attention to fixing the foundation, checking the tightness of each component, checking the tightness of the belt, checking idling, feeding evenly, paying attention to the operation, avoiding long-term overload operation, etc. At the same time, regular inspection and maintenance include cleaning bearings, replacing screens and claws, hammers, etc., to ensure the normal operation of the equipment and extend its service life. There are many types of feed grinders, the most common ones are:

1. Double-roller feed grinder: Double-roller feed grinder adopts the principle of double-roller crushing, and continuously crushes, shears and crushes materials through two sets of rollers rotating in opposite directions, so as to achieve the purpose of crushing. The advantages of the roller feed mill are good crushing effect and high output, but poor adaptability to materials, and it is not suitable for materials with high water content and high viscosity.

2. Hammer feed mill: The hammer feed mill uses high-speed rotating hammers to crush the materials. The shape and arrangement of the hammers have a great influence on the crushing effect. The advantage of the hammer feed mill is that it has strong adaptability to materials and can crush various types of materials, but the crushing effect is relatively poor and the output is also low.

3. Claw feed mill: The claw feed mill adopts the claw crushing principle, and shears and crushes the materials through multiple claws to achieve the purpose of crushing. The advantages of the claw feed mill are good crushing effect and high output, but poor adaptability to materials, and it is not suitable for materials with high water content and high viscosity.

When choosing a feed mill, it is necessary to comprehensively consider factors such as production capacity, crushing object, discharge method, supporting power, dust and noise. At the same time, when using the feed grinder, you need to pay attention to fixing the foundation, checking the fastening of each component, checking the tightness of the belt, checking idling, feeding evenly, paying attention to the operation, avoiding long-term overload operation, etc. Regular inspection and maintenance include cleaning the bearings, replacing the screen and claws, hammers, etc., to ensure the normal operation of the equipment and extend its service life.
