Description

Technical Field

[0001] The utility model relates to the technical field of Raymond mills, in particular to a Raymond mill for producing barium sulfate. Background Art

[0002] Barium sulfate is a white amorphous powder, which is difficult to dissolve in water, acid, alkali or organic solvents. Barium sulfate is used in radiological examinations, mainly because it can absorb X-rays in the gastrointestinal tract and develop images. Therefore, barium sulfate is mainly used as a gastrointestinal contrast agent. In the production process of barium sulfate, it needs to be crushed by a Raymond mill, which can grind barium sulfate through the combination of grinding rollers and grinding rings. Traditional Raymond mills will generate certain vibrations when working, which is easy to cause noise pollution to the working environment;

The support member extends downward from the first plate and surrounds the base, the body and the motor to form a support between the body and the foundation, overcoming the technical problem of large vibration during operation. Although it is convenient to reduce the noise pollution of the working environment caused by the vibration during operation, barium sulfate is prone to caking when left for a long time. The Raymond grinder is not convenient for fully grinding the agglomerated barium sulfate, and uneven grinding and crushing are likely to occur, thereby reducing the crushing effect.
