Today, I will talk about the principles of the air current crusher. The ultrafine pulverizer is composed of silo, mechanical pulverizer, air blower, cyclone, vibrating screen, liquid nitrogen tank, etc., the deep-cooling pulverizer system is refined by liquid nitrogen as a cold source, and it is crushing at low temperatures by cooling. After the crushing state, enter the mechanical pulverizing cavity through the impeller high speed rotation, the material and the blade, the tooth disc, the material and the material are enrolled under the integrated effect of collision, shear, friction, etc., to achieve a crushing effect. Ultrafine pulverizer is low, and all of the lifescas is used in high quality wear-resistant materials at home and abroad. It has long service life. A small amount of easy wear parts are made of special hard resistance, small size, light weight, easy to replace the accessories. After the airflow pulverizer is filtered, the pulverizing cavity is sprayed through the Raval nozzle, and the material is repeatedly collided, friction, shear and pulverized, and pulverized material in the intersection of the multi-shaped high-pressure airflow. Next, the rising airflow is moved to the hierarchical region, and the crude material is separated under the powerful centrifugal force generated by the high-speed rotation, the fine particles that meet the particle size requirements are collected by the grading wheel into the cyclone and the dust collector, and the crude particles drops to the pulverization. The district continues to smash. The principle of the airflow pulverizer is introduced below.
This paper introduces the principles, characteristics and applications of the air grade machine, and describes the principles, operations and maintenance of the air grade machine. Therefore, for these content, the small version does not repeat it. However, its operational rules have not been explained before, so the following versions will take some time and energy to explain this knowledge point so that you can know how to properly operate this machine and equipment. The operational rules of the air classifier include: (1) foreign matter or debris is not allowed in the air grade machine, otherwise the equipment will be damaged. (2) Before the device is started, the lubrication of its bearings and reducers should be checked. Whether the lubrication is good, whether there is a problem that needs to be handled. (3) Check if the amount of the reducer is sufficient, whether the oil supply of the bearing refueling device is normal. (4) Whether the fasteners such as screws are tightened, whether the blade is serious, and it needs to be replaced. (5) Whether the electrical switch, the limit switch is intact, whether it is normal to work, the coupling, belt, and gears are intact, whether the electrical facilities are sensitive and reliable. (6) When the air grading machine works, the operator is not allowed to leave, not to turn the contactor portion, or move the protective cover at will. (7) When using a grading machineAt any time, you should pay attention to its abnormal phenomena. Once a fault occurs, the device should be cut off immediately, and the professional maintenance personnel should be treated, and the equipment shall not be damaged without authorization.
Welcome to the above principles about the airflow pulverizer.
