6R4525 Raymond Roller Mill

6R4525 Type White Color Vertical Barite Raymond Roller Mill Grinding Barite Coal Bentonite Ceramics


6r4525 type white color vertical barite raymond roller mill is also known as Raymond mill, Raymond mill, high efficiency Raymond mill and high pressure rotary roller mill. It is suitable for all kinds of mineral powder preparation and coal powder preparation, such as raw material ore, gypsum ore, coal and other materials fine powder processing.

Barite Raymond mill is a new generation of pulverizing equipment improved on the basis of traditional Raymond mill. It is a commonly used industrial pulverizing mill. It is suitable for the preparation of various mineral powder and pulverized coal, such as the fine powder processing of raw material ore, gypsum ore, coal and other materials. From the appearance, the barite mill is like a steel container, with air inlet and outlet, and feed inlet in the middle. The shape is similar to the traditional Raymond mill. The rotary center line of Raymond grinding rod is vertical. The motor at the lower part of barite mill drives the internal grinding rod and disc to rotate to crush or grind the materials to be ground. The finished materials are blown up by the air inlet. There is a separator in the upper part of the mill to separate the coarse and fine powders, and then the air through the mill is taken out and collected from the air outlet.


Working principle:

During the operation, 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 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, and the crushed material is reached due to the rolling and rolling of the grinding roller The purpose of the material.

Due to the moisture content of the material in the Raymond Mill room, the heat generated during grinding causes the gas evaporation in the mill chamber, which changes the gas flow rate, and the connection of the pipes of the whole machine is not tight, so that the external gas is inhaled, which increases the air volume of the circulating air flow, resulting in less powder output and even explosion of the pulverizer. Therefore, the new European ladder type pulverizer has been provided with explosion-proof measures on the upper part of the machine body At the same time, the balance of air flow can be achieved by adjusting the residual air pipe between the fan and the main machine, and the surplus gas is introduced into the small cyclone collector to collect the fine powder brought by the residual gas. Finally, the upper exhaust pipe of the small cyclone collector is discharged into the atmosphere or introduced into the dust collector to exhaust the air However, the technical requirementsfor operators are relatively high, and need to be found and adjusted in time.



1. Three dimensional structure, small floor area, complete set of strong, from block material to finished powder alone into a production system.
2. The transmission device of the machine adopts sealed gear box and belt wheel, which has stable transmission and reliable operation.
3. Strong complete set, from block material to finished powder independent production system;
4. It can be used for grinding a variety of materials with hardness below grade 7.
5. Under the action of high-pressure spring and the structure of vertical squirrel cage analyzer, the passing rate of finished product is greatly improved, and there is no obvious granule.
6. It is a self-made system with less production links. Materials less than 30mm can be directly processed by machine.
