Abstract
The invention discloses a grading lining plate which is mounted on the inner surface of a barrel body of a ball mill. The grinding lining plate comprises a body, wherein the lower end of the body is provided with a circular-arc surface which is matched with the inner surface of the barrel body of the ball mill; the front end and the rear end of the circular-arc surface are in circular-arc connection with a front plane and a rear plane which extend towards the revolving center of the circular-arc surface respectively; the left end of the circular-arc surface is in upwards circular-arc connection with an inclined plane which inclines towards the right upper side; the right end of the circular-arc surface is in upwards circular-arc connection with a vertical plane; the upper end of the body is provided with a working inclined surface; the higher end and the lower end of the working inclined surface are in circular-arc connection with the inclined plane and the vertical plane; the front and rear ends of the working inclined surface are respectively in circular-arc connection with the front plane and the rear plane; four grooves which extend to the lower ends from the high ends and have arc-shaped sections are formed in the working inclined plane; the adjacent grooves are in circular-arc connection; the two ends of each groove are in circular-arc connection with the inclined plane and the vertical plane respectively; rectangular pits are formed in the circular-arc surface; bosses are arranged on the centers of the rectangular pits; step through holes which penetrate through the bosses and the working inclined plane are formed in the centers of the bosses.
Description
Technical field
The present invention relates to a kind of classifying lining board.
Background technology
Whole grinding made by current cement grinding many employings ball mill.At material from bistrique to grinding tail by the process of grinding, particle diameter progressively successively decreases.According to crushing material characteristic, require that in mill, steel ball also distributes by domain size distribution rule from bistrique from big to small to mill tail.
For realizing above-mentioned requirements, ball mill often takes the form in point storehouse to meet corresponding relation along axis, and because limiting by factors, a point storehouse can not be ad infinitum many, are often only divided into two to three storehouses.Therefore, behind point storehouse, steel ball only meets corresponding relation roughly, and due to the fluctuation in material filling and operation in same storehouse, the steel ball of size diameter is often in uniform contrary distribution even, is difficult to the corresponding requirement meeting sphere diameter and material particular diameter.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of classifying lining board.
The technical solution adopted for the present invention to solve the technical problems is: a kind of classifying lining board, be arranged on ball mill barrel inner surface, comprise body, body lower end has the arc surface matched with ball mill barrel inner surface, before arc surface, the frontal plane that the rear end difference circular sliding slopes directed circle cambered surface centre of gyration extends and back plane, arc surface left end is the inclined-plane that tilts, the oriented upper right side of circular sliding slopes upwards, arc surface right-hand member upwards circular sliding slopes has vertical guide, described body upper end has inclined working, the height of inclined working, low side respectively with inclined-plane and vertical guide circular sliding slopes, before inclined working, rear end respectively with frontal plane and back plane circular sliding slopes, inclined working offers four and lead to low side from high-end, cross section is the groove of arc, adjacent grooves circular sliding slopes, groove two ends respectively with inclined-plane and vertical guide circular sliding slopes, described arc surface is provided with rectangle pit, rectangle pit centres is provided with boss, boss center is provided with the step through-hole running through boss and inclined working.
Described step through-hole comprises the circular hole of boss side, the elliptical aperture of inclined working side and transitional pore, and circular hole is communicated with elliptical aperture by transitional pore.
Described arc surface offers two longitudinal flutings and two transverse concave grooves.
The invention has the beneficial effects as follows: the present invention is arranged on ball mill barrel inner surface, in grinding machine axial slices, the inclined working of this classifying lining board is high-end towards mill tail, low side is towards bistrique, inclined working offers the groove for promoting steel ball, during grinding machine work, the steel ball be in inclined working enters and leaves a little, because inclined working is to the support force of steel ball, bistrique is partial in the direction that leaves of steel ball, because the steel ball varied in size has the inertia varied in size, in mill, steel ball also just distributes by domain size distribution rule from bistrique from big to small to mill tail, thus solve the problem proposed in background technology.
