A pulverizer is a device used to grind and process materials such as ores. It can crush materials into smaller particles, and then supply them to the production of other equipment or use in various industries. Grinding machine is widely used in the grinding and processing of mineral raw materials in metallurgy, building materials, chemical industry, mining and other fields.
After the material is crushed to the required particle size, the material is sent into the storage hopper by the elevator, and then the material is evenly and continuously sent into the main grinding chamber of Raymond Mill through the vibrating feeder. When the grinding roller rotates, it swings outward due to the centrifugal force and presses tightly on the grinding ring. The spatula scoops up the material to be sent between the grinding roller and the grinding ring to make the grinding roller roll, so as to achieve the purpose of crushing. The fine powder after the crushed material is brought into the analyzer for sorting along with the circulating air of the blower. The coarse material falls back for regrinding, and the qualified fine powder enters the finished cyclone powder collector along with the airflow, and is discharged through the powder outlet pipe. That's the finished product.
In the Raymond mill chamber, the material to be ground contains a certain amount of water, heat is generated during the grinding process, the water vapor evaporates, the pipeline connection of the whole machine is not tight, the external air is sucked in, and the circulating air pressure is increased to ensure that the mill is under negative pressure. state. Working in this state, the increased air flow is discharged into the dust collector through the residual air pipe, and then discharged into the atmosphere after purification.
The grinding machine is composed of main machine, classifier, blower, finished product cyclone separator, pipeline device, motor and so on. The main engine is mainly composed of frame, air inlet volute, blade, grinding roller, grinding ring, cover, motor and so on. Auxiliary equipment includes jaw crusher, bucket elevator, electromagnetic vibrating feeder, electric control cabinet, etc., and users can choose flexibly according to the site conditions.
