Raymond machine model and its working principle:
There are many models of Raymond mills: 3R.4R.5R.6R. 2615 2715 2716 and 3016 3216 4119 suspended roller Raymond mills.
Take the most commonly used 3R Raymond pulverizer as an example. The work process of the pulverizer is mainly to feed the materials to be crushed into the machine from the feed port on the side of the main casing, relying on 3 grinding rollers suspended on the plum blossom rack. The device revolves around the vertical axis, and the colleague itself rotates. Due to the centrifugal force during rotation, the grinding roller swings outwards and presses against the grinding ring, so that the blade scoops up the material and sends it between the grinding roller and the grinding ring. The rolling of the roller achieves the purpose of crushing the material.
Note: (The "R" in the Raymond mill here means the grinding roller. The number of R in the mill indicates how many roller devices there are.)
After the material is ground, the fan blows the wind into the main casing and blows up the powder until it reaches the analyzer above the grinding chamber for sorting. The coarse material falls into the grinding chamber for regrind, and the fineness meets the specifications with the airflow It enters the cyclone collector and is discharged through the powder outlet pipe after collection, which is the finished product. The air flow returns to the fan from the return air pipe at the upper end of the cyclone. The air path is circulated and flows under negative pressure. Due to the water content of the material, the water evaporates in the grinding chamber and generates gas, which causes the air volume of the circulating air path to increase. , The excess air volume is discharged through the exhaust pipe between the fan and the main engine, and enters the small cyclone collector for purification treatment.
Raymond mill price:
The price of Raymond pulverizer ranges from several thousand yuan to several hundred thousand yuan, depending on the specific model.
