The advantage of Raymond mill 1700 for grinding limestone is that 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, and the grinding The rollers rotate 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 is crushed and grinded by the grinding roller. Start the blower motor to drive the airflow to the inside of the through-shaft. When the through-shaft drives the blower wheel to rotate, the airflow is blown from below the breathable ring to blow up the dust. This achieves the effect of blowing the crushed particles to prevent them from accumulating at the bottom, and solves the problem of particles. The problem of accumulation after crushing cannot be collected.Raymond mill 1700 has a new structure of plum blossom frame and longitudinal swing grinding roller device, which is advanced and reasonable in structure. The machine has very little vibration, low noise, smooth mechanical operation and reliable performance. It has sufficient experience and advantages in grinding limestone.
