Description
Technical field
The present invention relates to a kind of flour mills, more particularly to a kind of Raymond mill with embedded grinding roller and bull ring.
Background technique
Raymond mill is also known as raymond mill, is a kind of height novel, efficient, using closed cycle that can replace ball mill
Thin powder manufacturing apparatus.The Raymond mill is adapted to the industries such as Medium and smaller mines, chemical industry, building materials, metallurgy, refractory material, glass, cement.
Raymond mill at work, by the feed hopper addition machine of material slave housing side for needing to crush, by suspension
Burnisher apparatus on host plum blossom frame revolves around vertical axis, while rotation itself, the work of centrifugal force when due to rotation
With grinding roller is swung out, and is pressed in bull ring, so that perching knife is scooped up material and is sent between grinding roller and bull ring, because of the rolling compaction of grinding roller
And achieve the purpose that comminuting matter.
But Raymond mill, after a period of time that works, grinding roller and bull ring will be worn due to transition contact, and cause to grind
Grinding distance between roller and bull ring becomes larger, more it is essential that this abrasion between grinding roller and its bull ring, has not been
Full uniform wear, the position of this abrasion leads to not obtain enough fine powders when grinding material, and also will cause
Thicker material is ground inside wide arc gap between grinding roller and bull ring.
Therefore, when Raymond mill worked to certain service life, the corresponding bull ring of grinding roller is can not to contact, Jin Erwu
Method achievees the purpose that grinding fine grinding, and usually used way is that replacement or maintenance processing are carried out to grinding roller in the prior art.
In the implementation of the present invention, the inventor finds that the existing technology has at least the following problems:
If 1, replacing grinding roller, due to the heavier-weight of grinding roller, install relatively complicated；
If 2, safeguarding grinding roller, needs to stop to grind, be cleared up for a long time, sweep and repair, just can solve mill
The problem of can not being contacted between the corresponding bull ring of roller.
