一、Raymond Mill Machine Introduction1.Structure:The overall structure of the Raymond Mill Machine is a vertical structure, and its main components include a host machine, an analyzer, a fan, a finished cyclone separator, a powder cyclone separator, and an air duct. Among them, the main machine consists of a frame, an air inlet volute, a blade, a grinding roller, a grinding ring, a cover, etc.2.Working Principle:Raymond Mill Machine mainly relies on the electric motor to drive the grinding roller and the grinding plate to rotate at high speed to realize the grinding process of the material. At the same time, the wind force from the air inlet and outlet is used to blow up the material respectively for separation and collection.When working, the materials that need to be crushed are sent to the storage hopper by the elevator, and then the materials are evenly and continuously sent into the main grinding chamber of the Raymond mill through the vibrating feeder. Due to the centrifugal force during rotation, the grinding roller swings outward. , press the grinding ring tightly, the shovel blade scoops up the material and sends it between the grinding roller and the grinding ring, and the purpose of crushing is achieved due to the rolling of the grinding roller.3.Use:Widely used in barite, calcite, potassium feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, insulation materials, etc. High-fine powder processing of more than 300 kinds of non-flammable and explosive materials in mineral, chemical, construction and other industries with a hardness of no more than 7 and a humidity of less than 6%.It is widely used in important fields such as power plant desulfurization, mining water conservancy, construction and building materials.二、Performance advantages1.

It operates stably and has low noise, and can achieve certain environmental protection effects.3. The internal grinding device of the Raymond Mill Machine adopts overlapping multi-stage sealing, which ensures smooth transmission and reliable operation.4. The core part of the Raymond Mill Machine uses wear-resistant parts to extend its service life and reduce subsequent maintenance costs.三、Maintenance1. Why is the grinding roller and ring of the Raymond mill easily worn?The grinding roller device is mainly used for grinding materials. It is a component that directly contacts the material, so it is often easily damaged and requires regular maintenance. How to reduce maintenance costs? It is necessary to add engine oil within the specified time, and pay attention to the hardness and particle size of the grinding material to reduce the friction between the grinding roller devices. Of course, if the grinding roller is seriously damaged, it must be replaced in time.2. Maintenance of Raymond Mill Machine accessories(1) If the grinding roller and ring are used for more than 500 hours, the grinding roller sleeve must be replaced.(2) The bearings and bearing chambers must also be cleaned to ensure appropriate clearances.(3) When the host machine is running, unplug the power supply if something goes wrong. When shutting down, the Raymond mill will idle for 1 minute.
