Abstract

The utility model relates to a disc mill for superfine rubber disintegrating mills, which is composed of a fixed and a moving disc mills. The fixed and the moving disc mills 8, 1 are respectively provided with a plurality of fixed and moving knife troughs 9, 12. The fixed and the moving disc mills are uniformly divided into mill chambers 5, 4 and disc bodies 7, 2. The fixed and the moving knife troughs divide the mil chambers 5, 4 into inner mill chambers 10, 13 and outer mill chambers 11, 14. The utility model is characterized in that the fixed and the moving mill chambers 5, 4 are made of hard alloy materials; the outer mill chambers 11, 14 are assembled with a plurality of hard alloy sheet materials. The utility model has the advantages of good abrasive resistance, uniform disintegrated material with a fineness of 80 to 120 meshes, high disintegrating speed, high efficiency, stable quality, no crack on the mill chambers, long service life, etc.

Description

Ultra-fine rubber crusher mill

The utility model relates to a kind of ultra-fine rubber crusher, relates in particular to a kind of ultra-fine rubber crusher mill, belongs to the size reduction machinery technical field.

Mill is the core component of ultra-fine rubber crusher, and the quality of mill quality directly has influence on the fineness and the quality of rubber powder.Existing mill is made up of fixed, the movable grinding disc of mutual break-in.Fixed, movable grinding disc comprises disk body and mill chamber.All have some fixed, moving knife grooves on fixed, the movable grinding disc, fixed, the moving knife groove will be decided, moving mill chamber is separated into inner grinding cavity and outer grinding cavity.Because the mill chamber of mill is the monolithic construction of being made by the not too high monoblock Vc12 steel of hardness, so deposit the problem with following three aspects.

1, because the hardness of mill chamber material is not enough, its wearability extreme difference, very easily wearing and tearing, general powder is pulverized two classes, and promptly to begin to wear and tear, produces the high inner grinding cavity of outer grinding cavity of mill chamber low, and the many pits of appearance are on the rise later in the mill chamber, cause the powder fineness too low, have only about 60 orders, and very inhomogeneous;

2, because inside and outside mill chamber is a monolithic construction, outer grinding cavity is subjected to calmly, the effect of the significant shear power of the moving knife groove edge of a knife, very easily produces the crack in cutter groove groove point direction, causes whole mill to be scrapped:

3, because the heavy wear of mill mill chamber, making between fixed, movable grinding disc is not to shear and an abrasive action rising, but rubber grain friction mutually in mill chamber.And the toughness of rubber is high, and fricative temperature is serious and sharply rise along with abrasive disk abrasion, and temperature uncontrollablely causes the serious sintering of rubber powder, causes that rubber degenerates as a result, has directly influenced the quality of rubber powder.

The purpose of this utility model is to provide a kind of mill chamber wearability the good and difficult ultra-fine rubber crusher mill that produces the crack.

The utility model is achieved in that a kind of ultra-fine rubber crusher mill, fixed, movable grinding disc by mutual break-in are formed, calmly, all have some fixed, moving knife grooves on the movable grinding disc, fixed, movable grinding disc is divided into mill chamber and disk body two parts, fixed, moving knife groove is separated into inner grinding cavity and outer grinding cavity with mill chamber, mill chamber fixed, movable grinding disc is made by Hardmetal materials, and outer grinding cavity fixed, movable grinding disc is assembled by some carbide alloy sheet materials.

The utility model can also be achieved in that above-mentioned fixed, moving outer grinding cavity is double-deck concentric annular structure, cross arrangement between each sheet material.

The material of mill chamber of the present utility model is a wolfram steel.

Compare with existing ultra-fine rubber crusher, owing to mill chamber fixed, movable grinding disc of the present utility model is made by Hardmetal materials, and its outer grinding cavity is assembled by some carbide alloy sheet materials intersections, therefore has following advantage:

1, wearability is good, powder evenly and fineness can reach the 80-120 order, and the outer grinding cavity of mill can not produce crack, mill long service life;

2, output height can class Three be produced continuously, does not need frequent shutdown inspection, the fast efficient height of pulverizing speed;

3, steady quality is reliable, and temperature control is steady, and the rubber powder does not have sintering, degradation phenomena.

Fig. 7 is the D-D profile of Fig. 5.

Below in conjunction with accompanying drawing the utility model being done one describes in detail:

Shown in Fig. 1-7, the utility model is made up of fixed, the movable grinding disc 8,1 of mutual break-in.Calmly, all have some fixed, moving

knife grooves

9,12 on the movable grinding disc 8,1, fixed millstone is provided with charging aperture 6, movable grinding disc is provided with storage hole 3, fixed, movable grinding disc is divided into disk body 7,2 and mill chamber 5,4 two parts, fixed, moving knife groove is separated into

inner grinding cavity

10,13 and outer grinding cavity 11,14 with mill chamber 5,4, and mill chamber is made by Hardmetal materials.Outer grinding cavity 11,14 is assembled by some Hardmetal materials, can be made into double-deck concentric annular structure among the figure, cross arrangement between each sheet material.Mill chamber of the present utility model can adopt wolfram steel or golden steel to bore and make.

During pulverizing, rubber grain is entered in the mill by the charging aperture 6 of fixed millstone 8, after shearing by the edge of a knife fixed, the moving knife groove the more inside and outside mill chamber in footpath overflow after levigate.
