Brief introduction to Raymond mill equipment

Raymond grinding machine is also called Raymond mill for short. It looks like an upright steel container from the shape, has inlet and outlet, and a feed port is set in the middle. According to different raw materials, fineness and capacity, FTM Machinery has three series of corresponding grinding mills: high-pressure mill, high-strength mill, and Raymond mill.

Raymond mill is mainly used for barite, calcite, potassium feldspar, limestone, talc, white stone, gypsum, etc. The Moh’s hardness of any raw material is no more than 9.3, and the humidity is less than 6%. The size of finished materials can be adjusted in the range of 40-400 mesh. A single Raymond mill’s processing capacity can reach to 60TPH.

Raymond grinding mill machine is widely used in the grinding of mineral products in metallurgy, building materials, chemical industry, mining and other fields. It is suitable for processing various non-flammable and explosive materials with Mohs hardness below 7 and humidity below 6%. Finished product fineness is between 613μm and 44μm, the combination of analyzer and fan can meet the requirements of different users.
1.Strong system and high screening rate
2.Smooth transmission and high wear resistance
3.Easy to control and easy to maintain

The structure of Raymond mill machine

Raymond mill consists of main engine, analyzer, fan, finished cyclone, fine powder cyclone and duct. And the main engine is made up with rack, inlet volute, blade, grinding roller, grinding ring, casing. Generally, users will also choose a jaw crusher, bucket elevator, electromagnetic vibrating feeder, etc. as auxiliary equipment according to their own needs.

The structure of Raymond mill

How does a Fote Machinery raymond mill work?

Raymond mill grinds the material by the mutual extrusion of roller and grinding ring. When the Raymond mill is working, the transmission drives the roller shaft to make a rapid rotary motion. The action of the grinding roller is a fixed grinding ring. The grinding roller acts on the fixed grinding ring. When the material is fed into the body through the feeder, a blade installed at the front of roller continuously feed the material into grinding zone between the grinding roller and grinding ring.

Since the grinding roller is revolving along the axis, it continuously rolls outward and gradually approaches the grinding ring, and finally presses against the grinding ring. Meanwhile, the material mixed between the grinding roller and grinding ring is crushed by the pressing action, thus completing the entire grinding work.

Clearly visiable grinding process

Wind selection process of raymond mill grinding machine

After the material is ground, the fan blows up the powder, and sorts it through an analyzer placed above the grinding chamber. If the material is too thick, it will fall into the grinding chamber and re-grinds, while the fineness that meets the requirements will enter the cyclone collector with the wind flow. After collection, it is discharged through the powder outlet, which is the finished product. The wind flow is returned to the fan by the return air duct at the upper of a large cyclone collector.

The winding path is cyclic and flows under negative pressure. The wind of the circulating air path is discharged through the exhaust pipe between the fan and the main engine, and then enters the small cyclone collector for purification treatment.

Advantages of Fote Raymond Mill

1.Compared with other grinding equipment, Raymond mill has a higher screening rate of 99%.

2.Raymond mill uses the a sealed gearbox and pulley to drive the device. The vulnerable and easy-to-wear parts are made of high-quality steel, which prolongs its service life and makes the rotation more stable and reliable.

3.The whole airflow system is closed and circulates under the negative pressure state. The increased air volume enters the small cyclone collector through the exhaust pipe in the middle of the host, and is removed after purification treatment, which meets environmental protection requirements.

4.The Raymond mill produced by FTM company adopts PLC electrical automation control, which is convenient to operate, reduces maintenance costs, and achieve a good production environment with low noise and less pollution.

5.Milling fineness can be adjusted freely between 80-800 mesh, so Raymond mill’s applicability is more flexible and extensive. FTM Machinery’s Raymond Mill is the best choice for non-metallic ore grinding.

6.The replacement cycle of the grinding roller and grinding ring are long, which solve the Raymond mill problem that centrifugal pulverizer wear parts replacement cycle is short.
