Raymond mill, also called Raymond roller mill, combines grinding, classifying, and if necessary, drying, in one machine to produce precisely sized powders to meet exact production specifications. It is an efficient fine grinding machine for large-scale powder production.
The fineness of the Raymond mill can be adjusted arbitrarily between 0.173mm and 0.044mm. The achievable upper particle size is 800 mesh.
Vibration damping avoids cracking or damage to the frame and return box due to long-term vibration and fatigue.
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.
