Raymond mill powder machine's Working principle
Raymond mill firstly grind the big block raw materials to needed feeding size, then materials will be transported to storage silo through the Ben elevator. Then by electromagnetic vibration feeder evenly to the host grinding chamber, the material in mill chamber will be grinded between rollers and rings, grinded powder will be brought to the analytical engine by the fan engine air. After have achieved the required powder fineness, the powder will enter into large cyclone collector through pipeline, separation and collection, the finished products will discharge from the unloaded. When the host is in the working process, shovel knife system has played a very important role. It located at the bottom rollers. During the synchronous grinding process between shovel knife and roller, materials will be scooped up and thrown into the gap between the mill roller and rolling ring to form mat layer which will grind the material into pieces under the function of outward squeeze pressure produced by the mill roller rotation.
Machine structural characteristics of Raymond mill powder machine:
1. The whole machine has vertical structure, cover a small area packing machine, strong systematicness, from raw materials roughmaching to delivery to milling and final packaging; it can be an independent production system.
2. Compared with other grinding equipment, screening rate can reach 99%.
3. Raymond mill host transmission device adopts sealed gear box and belt pulley, smooth transmission, reliable operation.
4. Important parts of Raymond milling machine adopt high quality castings and molding manufacture, fine technology, rigorous process, ensure the durability of the whole equipment.
5. Centralized control of the electrical system. Grinding workshop can realize the basic unmanned operation, convenient maintenance.
Raymond mill powder machine's care and maintenance
1. When using the machine, special people should be responsible for supervision, the operator must possess the necessary operation skill. Before installation, operators should receive necessary technical training, to understand the principle of grinding machine performance.
2. To make Raymond milling machine woke normally, you should formulate the “equipment maintenance safety operation system "can guarantee for the long safe operation of the mill, Also should have the necessary maintenance tools and grease and the corresponding parts.
3. Raymond milling machine should be repaired after be used for a period of time. At the same time, replace the milling roller, milling ring and shovel. Before and after usage of the roller device, connecting bolts, nuts should be carefully examined in order to see if they are loosened and if there is enough lubricating grease.
4. Replace grinding roll when using time is more than 500 hours, each of the rolling bearing in must be cleaned, replace the damaged parts timely, refueling tools can be manual pumps and butter gun.
