Cassava crusher structure principle
The main purpose
The cassava crusher is composed of three parts: main machine, auxiliary machine and electric control box. It has various features such as air selection, no screen, no screen, uniform particle size, etc. The production process is continuous. The 500-mesh ultrafine crusher reaches the international advanced level and is widely used in the crushing of materials in the pharmaceutical, energy, food and other industries.
Dry cassava pulverizer is a kind of micro pulverizer designed and developed by our company. The pulverization of materials and the classification of powder are installed in the same machine body, and they operate independently. The 500-mesh superfine crusher has the features of full-featured, compact structure, stable technical performance, low power consumption, wide application range, no dust generation, adjustable powder fineness (60-500 mesh), simple maintenance, etc., and is widely used in Energy, dyes, coatings, medicine, food and other industries in different fields of ultra-fine crushing, material crushing, classification to finished products are carried out in the same closed system, after dust treatment, no pollution, is the ideal set of equipment for environmental protection .
working principle
500 mesh dry cassava superfine crusher feeds the material into the crushing chamber between the body and the deflector through the screw feeder of the feeding port. Under the impact of the high-speed rotating blade in the crushing chamber, the material is thrown to the fixed body. Ring gear, causing impact, shearing, and material, blade, ring gear collision, friction, shearing alternately crushed. After the crushed material is pulled by the negative pressure airflow, the small powder particles overcome their own weight, and the airflow passes through the deflector and enters the classification chamber. The graded impeller is composed of blades. The high-speed rotating blades generate centrifugal force opposite to the negative pressure. The particles that sink into the impeller are affected by the centripetal force of the negative pressure airflow, the weight of the particles and the centrifugal force generated by the impeller. Due to its large mass, the particles (graded particle size) are thrown back to the crushing chamber to continue crushing. Particles smaller than the critical diameter enter the cyclone collector through the powder discharge pipe and are discharged through the discharge valve. The higher the rotation speed of the classifying impeller, the finer the classifying particles. Correcting the rotation of the classifying impeller is the decisive factor for controlling the particle size.
maintenance
1. During the production process, the bearing temperature rise must be checked frequently. When the temperature rise exceeds 50 ° C, the machine should be shut down to check the cause, and troubleshoot.
2. When the new machine is running, the transmission belt is easy to grow long. Pay attention to adjust the proper tightness of the belt to ensure the working life of the belt.
3. Frequently inspect the wearing parts and replace them in time to ensure the production volume.
4. Blades and liners should be checked for wear frequently. For example, after wear, productivity decreases, grain size becomes coarse, and wear is replaced immediately after wear is found.
5. The host and graded rolling bearings are greased, using 2 # white special grease (Q / SY-5-79), with a penetration of 265-295.
6. The grease changing period of the bearing is 2000 hours. The filling of the grease into the bearing cavity (upper side) or 3/4 (lower side) must not be excessively filled with grease, otherwise the bearing temperature will be too high.
7. The screw feeder lubricates the bearings. No need to add grease, but it should be cleaned regularly.
