Raymond mill


Raymond mill, also known as Raymond roller mill and Raymond grinding mill, is a kind of grinding equipment. The equipment adopts the advanced technology and structure of similar products, and is updated and improved on the basis of Raymond mill in the same industry. The mill has high efficiency, low power consumption, small floor area and small one-time investment. The grinding roller is tightly rolled on the grinding ring under the action of centrifugal force. Therefore, when the grinding roller and grinding ring are worn to a certain thickness, the output and fineness of the finished product will not be affected, and the replacement cycle of the grinding roller and grinding ring is long, thereby eliminating the shortcoming of the short replacement cycle of the wearing parts of the centrifugal crusher.


Application and scope of Raymond Mill

Raymond mill is widely used in more than 280 kinds of non flammable and explosive mineral, chemical and construction industries, such as barite, calcite, potash feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, thermal insulation materials, etc. the Mohr hardness is no more than 9.3, and the humidity is below 6%. In the process of high and fine milling, the size of finished product of R-Raymond mill can be adjusted arbitrarily within the range of 80-325 mesh, and some materials can reach 2000 mesh when they are high.

Performance characteristics of Raymond mill

1. High structure and technology: the transmission device of the main engine adopts sealed gear box and belt wheel, and the main shaft and plum blossom frame are reformed in favor of stability to make its operation more stable and reliable.

2. Durable parts: the structure of the grinding roller has been updated, so that the grinding roller and the grinding roller shaft can complement each other, improve the durability of the grinding roller and reduce the loss of wear-resistant parts.

3. Good grain size of finished product: the particle size of the finished product grinded by the equipment can be adjusted arbitrarily in the range of 80-325 mesh. When some materials are high, it can reach 600 mesh.

4. Safety and stability: there are explosion-proof measures on the upper part of the body of Raymond mill, which can greatly avoid the accidental injury caused by the explosion of Raymond mill.

Raymond mill structure

The structure of Raymond roller mill is reasonable and scientific. It is mainly composed of main engine, analyzer, blower, cyclone separator, pipeline device and motor. The main engine is composed of frame, inlet volute, blade, grinding roller, grinding ring and cover. Raymond machine with jaw crusher, bucket elevator, electromagnetic vibration feeder, electric control cabinet, etc., can be combined into a complete grinding production line, which can easily meet the requirements of 80-325 mesh for limestone, calcite, barite, bentonite and other materials.


Working principle of Raymond Mill

1. Raymond grinding process: when working, the materials to be crushed are added into the machine from the feeding hopper on the side of the machine cover. Relying on the grinding roller device suspended on the plum blossom frame of the main engine, it rotates around the vertical axis and rotates itself. Due to the centrifugal force during the rotation, the grinding roller swings outward and presses tightly on the grinding ring, so that the shovel picks up the material and sends it between the grinding roller and the grinding ring.The purpose of crushing materials is achieved by dynamic rolling.

2. Air separation process of Raymond Mill: after grinding materials, the fan will blow the air into the main shell and blow up the powder. The fine and coarse materials will fall into the grinding room for regrinding. The fineness that meets the specification will enter the cyclone collector with the air flow, and then it will be discharged through the powder outlet. The air flow is returned to the fan by the return air pipe at the upper end of the large cyclone collector. The air path is circular and flows under negative pressure. The increased air volume of the circulating air path is discharged through the waste gas pipe between the fan and the main engine, and then enters the small cyclone collector for purification treatment.
