Abstract
The utility model relates to a kind of grate plate, comprise matrix, matrix is provided with installing hole and grate hole, grate hole is concentric arrays, and it is the grid ribs of concentric arrays that body upper surface and lower surface are uniform-distribution with grate hole, the concave surface of the grid ribs of the upper surface of matrix is provided with grate hole, alloy-layer is filled with in the concave surface of the grid ribs of the lower surface of matrix, grate hole is through alloy-layer, and the crowning of alloy-layer and grid ribs maintains an equal level, and is provided with conical limit material hole in grate hole.The utility model has the advantages that: grate hole is concentric arrays, the resistance that material passes through is little, and throughput is many and not easily blocked; The grid ribs that body upper surface and lower surface are provided with and alloy-layer, can increase the intensity of matrix, extends the service life of matrix.
Description
Technical field
The utility model relates to a kind of grate plate.
Background technology
After ball mill is crushing material, the key equipment that conducting powder is broken, it is widely used in cement, nitrate goods, New Building Materials, refractory material, chemical fertilizer, black or the production industry such as non-ferrous metal ore and glass ceramics, carry out dry type or wet type grinding to various ore or other grindability materials, grate plate is the parts for screening materials carrying in ball mill, the grate plate of existing structure, the radial arrangement of grate hole, the resistance that material passes through is large, and throughput is few, easily blocked.Therefore, a kind of new technical scheme should be provided to solve the problem.
Summary of the invention
The purpose of this utility model is: for above-mentioned deficiency, provides a kind of composite roll.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of grate plate, comprise matrix, matrix is provided with installing hole and grate hole, grate hole is concentric arrays, and it is the grid ribs of concentric arrays that body upper surface and lower surface are uniform-distribution with grate hole, the concave surface of the grid ribs of the upper surface of matrix is provided with grate hole, alloy-layer is filled with in the concave surface of the grid ribs of the lower surface of matrix, grate hole is through alloy-layer, and the crowning of alloy-layer and grid ribs maintains an equal level, and is provided with conical limit material hole in grate hole.
The material of matrix adopts potassium steel.
Limit material hole is that elastic material is made
Due to the application of technique scheme, the utility model compared with prior art tool has the following advantages:
1, grate hole is concentric arrays, and the resistance that material passes through is little, and throughput is many and not easily blocked.
2, the grid ribs that is provided with of body upper surface and lower surface and alloy-layer, can increase the intensity of matrix, extends the service life of matrix.
3, be also provided with in grate hole conical limit material hole and limit material hole be made up of elastic material, can according to turnover material number expand, easy to use.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model embodiment one front view.
Accompanying drawing 2 is the rearview of the utility model embodiment one
In above accompanying drawing: 1, matrix, 2, installing hole, 3, grate hole, 4, grid ribs, 5, alloy-layer, 6, limit material hole.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
As illustrated in fig. 1 and 2, a kind of grate plate of the utility model, comprise matrix 1, matrix 1 is provided with installing hole 2 and grate hole 3, grate hole 3 is in concentric arrays, matrix 1 upper surface and lower surface are uniform-distribution with and the grid ribs 4 of grate hole 3 in concentric arrays, the concave surface of the grid ribs 4 of the upper surface of matrix 1 is provided with grate hole 3, alloy-layer 5 is filled with in the concave surface of the grid ribs 4 of the lower surface of matrix 1, grate hole 3 is through alloy-layer 5, the crowning of alloy-layer 5 and grid ribs 4 maintains an equal level, and is provided with conical limit material hole 6 in grate hole 3.
The material of matrix 1 adopts potassium steel.
Limit material hole 6 is made for elastic material
Grate hole 3 is in concentric arrays, and the resistance that material passes through is little, and throughput is many and not easily blocked.
The grid ribs 4 that matrix 1 upper surface and lower surface are provided with and alloy-layer 5, can increase the intensity of matrix 1, extends the service life of matrix.
Also be provided with in grate hole 3 conical limit material hole 6 and limit material hole 6 be made up of elastic material, can according to turnover material number expand, easy to use.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvement or replacement, these improve or replace and also should be considered as protection domain of the present utility model.
