Use and use scope editors

Raymond mill is widely used in barite, calcite, feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, insulation materials with hardness less than 9.3, high humidity fine powder processing in 6% the following non inflammable and explosive mineral, chemical, construction and other industries more than 280 kinds of materials, R type Raymond mill product size 80 - 325 orders within the scope of any regulation, part of the material up to 600 head.

Main structure editor

The structure of the machine is mainly composed of the main engine, the analyzer, the fan, the finished cyclone separator, the micro cyclone separator and the wind pipe. Among them, the host is composed of a machine frame, inlet volute, blade and grinding roller and grinding ring and shell composition.

The working principle of Raymond Mill:

When working, will need to crush the material from the cover side of the hopper into the machine, depending on the host hanging in the grinding roller frame plum, moves around the vertical axis, and its rotation, due to centrifugal force during rotation, the roller swings outward, tightly pressed on the grinding ring, between the shovel knife from the material to the grinding roller and grinding ring for rolling mill roller and achieve the purpose of crushing material.

Raymond Mill winnowing editor

After grinding, the fan will be blown into the host shell, blowing powder by grinding chamber is arranged above the analyzer for separation, fine through thick materials fall into the grinding chamber and re grinding, the fineness of the specifications of the wind flow into the cyclone collector, collected by the powder outlet, i.e.. The air flow is returned to the fan by the return air pipe at the upper end of the cyclone collector. The wind path is cycled and flows under the negative pressure state. The increase of the air volume of the circulating air passage is partly discharged by the exhaust pipe between the fan and the main engine, and then enters the small cyclone collector to purify it.

Use and maintenance editor

1, Raymond mill must have the necessary technical training for the operators before installation, so as to understand the principle and performance of Raymond mill and familiar with the operation rules of Raymond mill. In the course of the use of Raymond mill, the fixed personnel should be responsible for the management, and the operator must have a certain technical level.

2, in order to make Raymond Mill normal, equipment maintenance and safety operation system should be worked out to ensure long-term and safe operation of flour mills, and necessary maintenance tools, grease and corresponding accessories.

3, Raymond mill after a period of time, should also overhaul and repair replacement treatment on roller grinding ring blade wearing parts, grinding roller device to examine connecting bolts and nuts should be before and after use, to see whether there is loose, grease is full.

4, the Raymond Mill's roller device is used for more than 500 hours. When the grinding roller is replaced again, the rolling bearings must be cleaned, the damaged parts should be replaced in time, and the refueling tools can be operated by manual fuel pumps and grease guns.

5, shut down, stop feeding first, the main engine continues to rotate, make the remaining material continue to grind, after about a minute, it can turn off the main motor, stop grinding, and then stop fan motor and analyzer motor.

Performance feature editing

1., the whole machine is a vertical structure, with a small footprint and strong systematicness. From raw material rough machining to transportation to powder making and final packaging, the whole machine can become an independent production system.

2. compared with other grinding equipment, the screening rate is up to 99%.

The 3. main drive device adopts the closed gear box and the belt wheel, and the transmission is stable and the operation is reliable.

4. the important parts of Raymond mill are made of high quality castings and profiles, and the technology is fine, which ensures the durability of the complete set of equipment.

5. the centralized control is adopted in the Raymond mill electrical system, which is advanced and reasonable in the degree of automation.
