Raymond mill, also known as Raymond machine, the English full name: Raymond mill. It is a grinding equipment widely used in mining, cement and chemical industry, and is one of the important equipment for non-metallic minerals deep processing. Because of its stable performance, strong adaptability and high performance price ratio, Raymond mill has been popularized in the field of non-metallic minerals for more than 20 years. It is suitable for grinding non flammable and explosive materials such as non plastic ore, mineral soil, metal oxide, chemical compound, and so on, with the humidity of less than 6% and less than 6%. . Such as: talc, silica, graphite, fluorite, magnesite, bentonite, kaolin, clay and so on.

The whole machine consists of:

The structure of JL - 4528 type 6R Raymond machine is composed of main engine, classifier, pipe device, high pressure centrifugal fan and dust collector. Its subsidiary equipment is composed of jaw crusher, dustpan hoist, storage hopper, electromagnetic vibrating feeder and electric control cabinet.

The principle of Raymond Mill:

When the Raymond mill is working, the crushed material is added into the machine from the side of the hood shell. It depends on the roller device suspended on the main frame of the main engine. It revolves around the vertical axis and rotates itself at the same time. Because of the centrifugal force when rotating, the roller is swinging outward and pressed on the grinding ring, so that the spatula is shoveled to the material. Between grinding roller and grinding ring, the purpose of grinding material is achieved by rolling rolling of roller.

Operating procedures:

Before Raymond Mill opens, it is necessary to check the close closure of all the repair doors and check whether the gap between the palate plate of the crusher meets the size of the feed size, and the speed of the adjustment analysis machine should be approximate to the grain size requirement. Finally, open the machine in order.

1, open the bucket elevator; 2, open the Hubei crusher; 3, after the material stored in the silo, start the analysis machine; 4, start the blower (air load start, after normal operation reload); 5, starting Raymond mill, immediately start the main engine immediately start electromagnetic vibration feeder. At this time Raymond grinding is the beginning.

The operation sequence of Raymond mill is as follows: start up: hoist, crusher, analysis machine, fan, main engine, feeder.

When Raymond Mill stops, the following machines should be closed.

1, close the feeder and stop the feed first.

2. Stop the host in about one minute.

3, after blowing the residue of the powder, stop the blower.

4, finally close the analysis machine.

The order of Ramon mill shutdown is: feeder, main engine, blower, and analytics.

Note: after a certain amount of material transported to the silo, the hoist will stop the crusher first and then stop lifting. This should be changed by the storage capacity.

5, Raymond Mill in normal work is not allowed to refueling, to ensure production safety, pulverizer in any part of the abnormal noise, or the sudden increase in load should stop inspection immediately, to exclude faults, so as to avoid major accidents. When you continue to turn on the machine, you must remove the remaining material in the mill, otherwise the current will be too large when starting the machine, which will affect the start.

1. The whole machine is a vertical structure with small area and strong systematicness. From the rough processing of the raw material to the powder production and the final packaging, it can be an independent production system.

2. Compared with other milling equipment, the sieving rate is as high as 99%.

3. The main transmission device of Raymond mill is sealed gear box and belt pulley, with stable transmission and reliable operation.

4. The important parts of Raymond mill are made of high quality castings and profiles. The process is precise and rigorous, ensuring the durability of the whole set of equipment.

5. Centralized control is adopted in the electrical system. The mill can basically realize unmanned operation and maintenance.
