The main purpose
The SCR denitrification catalyst ultrafine crusher consists of three parts: host machine, auxiliary machine, and electric control box. It has a variety of properties, such as air separation, no screen, no net, uniform size, etc., and the production process is continuous. The catalyst ultrafine crusher has reached the international advanced level and is widely used in materials crushing in the pharmaceutical, energy, food and other industries.
The SCR denitrification catalyst superfine pulverizer is a high-efficiency fine pulverizer designed and developed by our company. The crushing of the material and the pulverization of the particles are carried out in the same body, and they operate independently. The catalyst ultrafine crusher has all functions, compact structure, stable technical performance, low power consumption, wide range of adaptability, no dust generation, powder fineness (60-500 mesh), simple maintenance, etc., widely adaptable to energy The ultra-fine grinding in different fields of dyes, paints, pharmaceuticals, foods, etc., the crushing and classification of materials to finished products are carried out in the same closed system. After dust treatment, no pollution, it is an ideal complete set of equipment for environmental protection.
working principle
The SCR denitrification catalyst ultrafine pulverizer is fed into the pulverization chamber between the body and the diversion ring through the feed screw feeder, and the crushing chamber is impacted by the blade rotating at a high speed so that the material is thrown onto the body and fixed thereon. Ring gear, causing impact, shear, and material and blade, ring gear collision, friction, shear alternately smash. After the crushed material, under the action of the pulling force of the negative pressure air flow, the small particles overcome their own weight, and follow the air flow over the diversion ring and enter the classifying chamber. The classifying impeller is composed of blades. The blades rotating at high speed produce centrifugal force opposite to that of negative pressure. The particles sinking into the blade are simultaneously subjected to the centripetal force of the negative pressure airflow, the weight of the powder and the centrifugal force generated by the impeller, and the diameter of the powder is greater than the critical diameter. The particles of (classified particle size) are thrown back into the crushing chamber for continued crushing due to their large mass, and particles smaller than the critical diameter are discharged into the cyclone collector through the discharge valve through the discharge tube. The higher the rotational speed of the classification impeller, the finer the grading particles, and the adjustment of the rotation of the grading impeller is the determining factor for controlling the particle size.
maintenance
1. During the production process, the temperature rise of the bearing must be checked frequently. When the temperature rise exceeds 50, it is necessary to stop the inspection, find out the reason, and troubleshoot.
2. When the new machine is in operation, the drive belt is easy to grow long. It is necessary to adjust the proper board tightness of the belt to ensure the working life of the belt.
3, wearing parts should always check and replace in time to ensure production.
4, the blade, liner should always check the wear and tear, such as wear, productivity, particle size becomes coarse, found immediately after the wear and tear.
5, the host and the classification of rolling bearings are grease lubrication, using 2 # white special grease (Q/SY-5-79), penetration 265-295.
6, the bearing of the fat replacement period of 2000 hours, the filling of the grease for the bearing cavity space (upper side) or 3/4 (lower side) must not be too much filled with grease, otherwise it will cause the bearing temperature is too high.
7. The screw feeder lubricates the bearing without adding grease, but it should be cleaned regularly.
