Abstract
The utility model relates to a grate plate, in particular to a diaphragm grate plate used for a ball grinder, and belongs to the technical field of ball grinders. The diaphragm grate plate comprises a grate plate base body (1), two ends of the grate plate base body (1) are provided with mounting holes (3) respectively, a plurality of grate holes (2) are arranged in the middle of the grate plate base body (1), the section of each grate hole is in a trapezoid shape, a chamfer is arranged at a small end of each trapezoid, and the grate plate base body (1) is made of high manganese steel. Since the section of each grate hole is in a trapezoid shape, and the chamfer is arranged at the small end of each trapezoid, the chamfer has a guiding function for materials through the grate plate, and passing resistance for the materials is lower. As a large end of each trapezoid faces to a discharge end when the grate plate is mounted, the materials are not easy to jam and the grate holes are not easy to block.
Description
(1) technical field
The utility model relates to a kind of grate plate, specifically relates to a kind of compartment grate plate that is used for ball mill, 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.The compartment grate plate is the parts that are used to sieve material in the ball mill, and the comb hole of existing compartment grate plate does not have guide function, and material is big by resistance, and the comb hole 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 material by the little and comb hole not susceptible to plugging ball mill compartment grate plate of resistance.
The purpose of this utility model is achieved in that a kind of ball mill compartment grate plate, it comprises the grate plate matrix, and grate plate matrix two ends are provided with installing hole, are characterized in: be provided with several comb holes in the middle of the grate plate matrix, the cross sectional shape in comb hole is trapezoidal, and trapezoidal small end place is provided with chamfering.
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 ball mill compartment of the utility model grate plate, the cross sectional shape in its comb hole is trapezoidal, and trapezoidal small end place is provided with chamfering, chamfering plays guide function to material by grate plate, the current resistance of material is less, and the trapezoidal big end in comb hole was towards discharge end when grate plate was installed, and the material that passes through is difficult for getting stuck, and the comb hole is difficult for blockage phenomenon.
(4) description of drawings
Fig. 1 is the generalized section of a kind of ball mill compartment of the utility model grate plate.
Wherein:
Grate plate matrix 1, comb hole 2, installing hole 3.
(5) specific embodiment
Referring to Fig. 1, the utility model relates to a kind of ball mill compartment grate plate, and it comprises grate plate matrix 1, and grate plate matrix 1 two ends are provided with installing hole 3, the centre is provided with several comb holes 2, comb hole 2 cross sectional shapes are trapezoidal, and trapezoidal small end place is provided with chamfering, should make the trapezoidal big end in comb hole towards discharge end during installation, can not adorn anti-, the compartment grate plate mainly is subjected to the extruding and the friction of abrasive body, and it is little to be hit, so grate plate matrix 1 material adopts potassium steel.
Claims (2)
1. ball mill compartment grate plate, it comprises grate plate matrix (1), and grate plate matrix (1) two ends are provided with installing hole (3), it is characterized in that: be provided with several comb holes (2) in the middle of the grate plate matrix (1), the cross sectional shape in comb hole (2) is trapezoidal, and trapezoidal small end place is provided with chamfering.
2. a kind of ball mill compartment grate plate according to claim 1 is characterized in that: the material of described grate plate matrix (1) adopts potassium steel.
