The R series mill is a classic Raymond mill. Hongcheng has upgraded the Raymond roller mill technology. It is an economical and applicable Raymond pulverizer.
Raymond roller mill, also known as R-series pendulum mill, originated in the 1880s and was invented by the Raymond brothers. After more than a hundred years of practice and continuous innovation and improvement, its structure has been perfected day by day. Guilin Hongcheng has adopted a new advanced technology to update the technical indicators of R series raymond roller mill.
Max feeding size:15-40mm
Capacity: 1-20t/h
Fineness: 38-180μm
Raymond Roller Mill are mainly composed of main machine, feeder, classifier, fan, pipeline device, storage hopper, electrical control system, collecting system, etc.
The main motor of the Raymond Roller Mill is mainly composed of a base, a center shaft frame, a grinding ring, a grinding roller assembly, a center shaft, a blade holder, a blade holder assembly and a cover. The grinding ring and grinding roller are made of wear-resistant materials, and their material-contacting surfaces are all subjected to wear-resistant treatment. The transmission system can adopt two modes: reduction drive and double drive. The classifier adopts turbo forced classifier, and the conveying and feeding system can be selected according to different materials. The collection system can be a closed loop collection system with double cyclone and pulse dust collector and an open loop system with full pulse collection. The control system can choose automatic control and remote control modes according to customer needs.
The material is crushed by jaw crusher into a particle size that meets the specifications, and is lifted to the storage hopper by the bucket elevator.
Then the feeder is quantitatively fed into the main machine cavity for grinding. The grinding roller device supported on the plum blossom frame in the main machine cavity rotates around the central axis, and the grinding roller swings horizontally outward under the action of centrifugal force, so that the grinding roller presses the grinding ring. , the grinding roller rotates around the grinding roller axis at the same time. The material raised by the rotating blade is thrown between the grinding roller and the grinding ring, and the grinding and grinding effects are achieved by the rolling of the grinding roller.
The ground powder is blown by the air flow of the blower to the classifier above the main machine for sieving. Those with excessive fineness still fall into the main machine for regrinding, and those with fineness that meet the specifications flow into the cyclone collector with the wind.
After collection, the finished product is discharged through the powder discharge pipe (the particle size of the finished product can be as high as 0.008mm). The purified air flows into the blower through the pipe at the upper end of the cyclone separator. The air path is circular. Except for the positive pressure from the blower to the grinding chamber, the airflow inside the other pipes flows under negative pressure, and the indoor sanitary conditions are better.
