Raymond mill model and its working principle!

Raymond mill has many models: 3R.4R.5R.6R. 261527152716 and 301632164119 suspension roll Raymond mill.

Working principle:

Taking the most commonly used 3R Raymond mill as an example, the working process of the pulverizer is mainly to add the material that needs to be crushed from the inlet of the side of the main engine shell, and rely on the 3 roller equipment hanging on the plum rack, revolving around the vertical axis, the colleague itself rotates, and the roller is swinging outward because of the centrifugal force when rotating. The grinding wheel is tightly pressed on the grinding ring, so that the scraper can shovel the material to the grinding roller and the grinding ring, and achieve the purpose of crushing material due to the rolling of the grinding roller.

The process of wind selection:

After the material is grinded, the fan blows the wind into the main engine shell, blowing powder up to the analyzer above the grinding chamber for sorting, passing the coarse material into the grinding room and regrinding. The fineness goes into the cyclone collector with the specifications, and after collecting the powder pipe, it is eliminated, that is the finished product. The air flow is returned to the fan at the upper end of the large cyclone. The wind is circulating and flows under the state of negative pressure. Due to the water content of the material, the moisture is evaporated in the grinding room and the gas is generated, which leads to the increase of the air volume in the circulating wind road. The excess air volume is discharged by the exhaust pipe between the fan and the main engine and enters the small cyclone collector. To carry out purification treatment.
