Abstract
The utility model relates to a grate plate, particularly relates to a grate plate with concentrically arranged grate holes and used for a ball mill and belongs to the technical field of ball mills. The grate plate comprises a grate plate basal body (1), wherein a mounting hole (3) and a plurality of grate holes (2) are formed on the grate plate basal body (1) respectively, the grate holes (2) are concentrically formed, and the grate plate basal body (1) is made of high manganese steel. The grate plate with the concentrically arranged grate holes has the advantages of small pass-through resistance of materials and more throughput of materials, and the grate holes are not easily blocked.
Description
(1) technical field
The utility model relates to a kind of grate plate, specifically relates to a kind of castor hole that is used for ball mill and is the grate plate that concentric circles is arranged, and belongs to the ball mill technical field.
(2) background technology
Ball mill is after the material fragmentation, the key equipment of pulverizing again.It is widely used in cement, nitrate goods, New Building Materials, refractory material, chemical fertilizer, black or production industries such as non-ferrous metal ore and glass ceramics, and various ores or other grindability materials are carried out dry type or wet type grinding.Grate plate is the parts that are used to sieve material in the ball mill, the grate plate of existing structure (as shown in Figure 1), and arrange radially in its comb hole, and material is big by resistance, and the less and comb hole of throughput is easily stopped up.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of castor hole to be the ball mill grate plate that concentric circles is arranged, and it is little to make that material passes through resistance, and throughput is more and the comb hole is difficult stops up.
The purpose of this utility model is achieved in that a kind of castor hole is the grate plate that concentric circles is arranged, it comprises grate plate matrix (1), grate plate matrix (1) is provided with installing hole (3) and several comb holes (2), is characterized in: described several comb holes (2) are concentric circles and arrange.
The material of described grate plate matrix adopts potassium steel.
Compared with prior art, the beneficial effects of the utility model are:
A kind of castor of the utility model hole is the grate plate that concentric circles is arranged, its comb hole is concentric circles and arranges, cylindrical shell drive abrasive body rotates with material during ball mill work, be the parallel moving line with abrasive body and material in comb hole that concentric circles arranges, material to pass through resistance little, the more and castor hole of throughput is difficult for stopping up.
(4) description of drawings
Fig. 1 is the structural representation that has the grate plate of arranging radially in the castor hole now.
Fig. 2 is the structural representation of the grate plate of concentric circles arrangement for a kind of castor of the utility model hole
Wherein:
Grate plate matrix 1, comb hole 2, installing hole 3.
(5) specific embodiment
Referring to Fig. 2, the utility model relates to a kind of castor hole and is the grate plate that concentric circles is arranged, and it comprises grate plate matrix 1, and grate plate matrix 1 is provided with installing hole 3 and several comb holes 2, and comb hole 2 is concentric circles arranges, and liner plate matrix 1 material adopts potassium steel.
Claims (2)
1. a castor hole is the grate plate that concentric circles is arranged, and it comprises grate plate matrix (1), and grate plate matrix (1) is provided with installing hole (3) and several comb holes (2), it is characterized in that: described several comb holes (2) are concentric circles and arrange.
2. a kind of castor according to claim 1 hole is the grate plate that concentric circles is arranged, and it is characterized in that: the material of described grate plate matrix (1) adopts potassium steel.
