Product features


Smooth rotation and reliable operation

The transmission device of the main machine of the Raymond mill adopts a sealed gearbox and a pulley, and the transmission is stable and the operation is reliable.

Easy to use

With centralized control electrical system, the workshop can basically realize unmanned operation

High screening rate

Compared with other milling equipment, the sieving rate is high, and the sieving rate is as high as 99%, which is generally beyond the reach of other milling equipment

The long service life of wearing parts

The wearing parts are made of high manganese steel, which has a long service life, and the motors are all national standard products

Working principle

Working principle

Step 1  The raw material is crushed into a specified particle size by the jaw crusher, lifted to the hopper by the bucket elevator, and then quantitatively sent to the crushing chamber by the feeder.

Step 2  A rotating shovel scoops up the ingredients and projects them between the rollers and the ring where the grinding takes place.

Step 3 The pulverized powder is blown into the classifier by the air blower for classification. Oversized particles fall into the grinding chamber for regrinding. Qualified powder flows into the cyclone collector through the classifier and is collected as finished product.

Step 4  To ensure that the Raymond mill works under negative pressure. The increased air flow enters the pulse dust collector through the pipeline, and is discharged into the atmosphere after purification. The dust-free operation in the workshop is realized through the pulse collector.
