Abstract

The utility model discloses a many grinding cylinder sand mill, grinding cylinder longitudinal symmetry are equipped with a plurality of baffles, and the main shaft passes in the middle of the baffle, leaves the space between main shaft and the baffle, falls into the little grinding cylinder of a plurality of with grinding cylinder. The main shaft is equipped with the main shaft cover, and the main shaft cover corresponds the position with the baffle and is equipped with the arch. Many grinding cylinder structure has the dispersion of grinding and internal classification effect, can make grinding material particle size distribution very narrow, and the material need not through manifold cycles, and easy operation is convenient, reduces the process.

Description

Many abrading cylinders sand mill

Technical field

The utility model belongs to sand mill, is specifically related to a kind of many abrading cylinders sand mill.

Background technology

Sand mill utilizes material pump by the solid-liquid mixtures material input grinding inner sleeve after the pre-dispersed wettability treatment of mixer, material is stirred by the disperser of High Rotation Speed together with the abrasive media in grinding inner sleeve, thus make the solia particle in material and abrasive media produce stronger collision, friction, shear action each other, reach the object accelerating levigate particulate and disperse agglomerations, the feed separation abrasive media after grinding distribution flows out from discharge nozzle.Horizontal sand mill is particularly suitable for the high and product that granularity requirements is thin of dispersion grinding viscosity, and the technique that present sand mill uses is that each batch materials repeatedly need circulate through outer setting and just can reach the granularity of needs.

Summary of the invention

In order to overcome the above-mentioned defect that prior art field exists, the purpose of this utility model is, provides a kind of many abrading cylinders sand mill, without the need to through repeatedly circulating, simple to operation, reduces operation.

Many abrading cylinders sand mill that the utility model provides, abrading cylinder is arranged with some baffle plates up and down, and main shaft passes in the middle of baffle plate, leaves space, abrading cylinder is divided into several little abrading cylinders between main shaft and baffle plate.Main shaft is provided with collar bush, and collar bush and baffle plate correspondence position are provided with projection.

Many abrading cylinders sand mill that the utility model provides, its beneficial effect is, many abrading cylinders structure has grinding distribution and internal classification effect, can make grinding material Unusually narrow particle size distribution, and material is without the need to through repeatedly circulating, simple to operation, reduces operation.

Accompanying drawing explanation

Fig. 1 is the overall structure schematic diagram of the utility model embodiment;

Fig. 2 is the enlarged drawing of local A in Fig. 1.

Mark in figure:

1. abrading cylinder; 2. baffle plate; 3. main shaft; 4. protruding; 5. collar bush.

Detailed description of the invention

With reference to the accompanying drawings, in conjunction with an embodiment, many abrading cylinders sand mill that the utility model provides is described in detail.

Embodiment

With reference to Fig. 1-2, many abrading cylinders sand mill of the present embodiment, abrading cylinder about 1 is arranged with some baffle plates 2, and main shaft 3 passes in the middle of baffle plate 2, leaves space, abrading cylinder 1 is divided into several little abrading cylinders between main shaft 3 and baffle plate 2.Main shaft 3 is provided with collar bush 5, and collar bush 5 and baffle plate 2 correspondence position are provided with protruding 4.

During work, in little abrading cylinder, grinding is continued in the position that abrasive media and relatively thick material are split into away from main shaft 3 because of the effect of centrifugal force, and comparatively thin near the raw meal particle size of main shaft 3, and the thinner material of granularity enters next little abrading cylinder under pump pressure.Many abrading cylinders structure has grinding distribution and internal classification effect, can make grinding material Unusually narrow particle size distribution.

Claims

1. the sand mill of abrading cylinder more than, is characterized in that: abrading cylinder is arranged with some baffle plates up and down, and main shaft passes in the middle of baffle plate, leaves space, abrading cylinder is divided into several little abrading cylinders between main shaft and baffle plate.

2. many abrading cylinders sand mill according to claim 1, is characterized in that: main shaft is provided with collar bush, and collar bush and baffle plate correspondence position are provided with projection.
