Description
Technical Field
The invention relates to the technical field of limestone material grinding, in particular to a dolomite anti-seizing grinding machine and a grinding method.
Background
The mill structure mainly comprises a main machine, an analyzer, a fan, a finished cyclone separator, a micro powder cyclone separator and an air pipe. The main machine consists of a frame, an air inlet volute, a scraper knife, a grinding roller, a grinding ring and a housing.
In general, when the grinder works, materials to be crushed are added into the grinder from a feed hopper on the side surface of a housing shell, and the grinder rotates around a vertical axis by virtue of a grinding roller device hung on a plum flower stand of a main machine, and simultaneously, the grinder rotates, and due to the action of centrifugal force in rotation, the grinder swings outwards and is tightly pressed on a grinding ring, so that a shovel blade scoops the materials between the grinder and the grinding ring, and the purpose of crushing the materials is achieved due to rolling and rolling of the grinder.
When the existing mill is used, the inventor finds that because the grinding rollers are connected through bearings when rotating, small particles of materials in the mill body can be accumulated in the rotating gap position of the grinding rollers in a large quantity due to sputtering of the materials after the grinding rollers are used for a long time. And the position of the rotating gap of the grinding roller can be obviously found, and the accumulation amount of the materials above is obviously larger than that of the gap below. Analysis has found that this occurs because the external blowing streams in a typical machine body are blown from below the machine body and flow from bottom to top in the matrix. Thus, the accumulated materials below the rotating gap are easier to blow off, and the materials above the rotating gap are accumulated in a large amount due to the problem of wind flow dead angles. When a large amount of materials are piled up, the autorotation of the grinding roller can be seriously influenced, so that the grinding effect of the grinding machine is greatly reduced, and the grinding roller is easy to damage due to long-time clamping of the grinding roller.

The rotation of shovel material portion combines the wind flow of blowing into in the material portion of blowing like this, will pile up the material of body bottom surface and shovel the material into abrasive material portion and carry out the crocus. Meanwhile, in the running process of the abrasive part, the first rotating shaft is used as the rotating center of the abrasive part, when the first rotating shaft rotates, the grinding roller mechanism which surrounds the first rotating shaft rotates on the other axis which is parallel to the axis of the body, so that the distance between the grinding end of the grinding roller mechanism and the inner wall of the body can be periodically changed, the sliding sleeve is sleeved outside the positioning rod due to the sliding sleeve along with the rotation of the first rotating shaft, and the grinding roller is always abutted with the inner wall of the grinding part under the action of the compression spring.
