Abstract
The invention discloses a separation bin grid plate of a cement grinding mill, relates to a grid plate, particularly relates to a separation bin grid plate for a cement grinding mill, and belongs to the technical field of cement grinding mills. The separation bin grid plate comprises a grid plate body made of wear-proof alloy cast steel, wherein the two ends of the grid plate body are respectively provided with a bolt hole, the middle of the grid plate body is provided with a plurality of grid gaps, the cross-sectional shape of each grid gap is a trapezoid, and the small end of each trapezoid is provided with a chamfer. According to the cement grinding separation bin grid plate provided by the invention, the cross-sectional shapes of the grid gaps are trapezoids, the small end of each trapezoid is provided with the chamfer, the chamfer can play the role of guidance through the grid plates, and the general resistance of a material is smaller; and when the grid plate is installed, the trapezoid big end of each grid gap faces to a discharge end, materials passing by the grid plate have less possibility of being blocked, and the grid gaps have less possibility of being subjected to a blocking phenomenon.
Description
Technical field
The present invention relates to a kind of grate plate, specifically relate to a kind of compartment grate plate for cement grinding mill, belong to the cement grinding mill technical field.
Background technology
Cement grinding mill is after the material crushing, the key equipment of pulverizing again.It is widely used in cement, silicate product, New Building Materials, refractory material, chemical fertilizer, black or the 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 for screening materials carrying in the cement grinding mill, and the comb seam of existing compartment grate plate does not have guide function, and material is large by resistance, and the seam of combing easily stops up.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, provide a kind of material to pass through the little and not susceptible to plugging cement grinding mill compartment grate plate of seam of combing of resistance.
The object of the present invention is achieved like this: a kind of cement grinding mill compartment grate plate, comprise the grate plate body that adopts wear-resistant alloy cast steel to make, the two ends of grate plate body arrange respectively bolt hole, the middle part of described grate plate body arranges several seams of combing, the cross sectional shape of each seam of combing is respectively trapezoidal, and trapezoidal small end arranges chamfering.
The cross sectional shape of comb of the present invention seam is trapezoidal, and trapezoidal small end place is provided with chamfering, and chamfering plays guide function to material by grate plate, the current resistance of material is less, and the trapezoidal large end of seam of combing when grate plate is installed is towards discharge end, and the material that passes through is difficult for getting stuck, and the seam of combing is difficult for blockage phenomenon.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
As shown in Figure 1, be cement grinding mill compartment grate plate, comprise the grate plate body 1 that adopts wear-resistant alloy cast steel to make, the two ends of grate plate body 1 arrange respectively bolt hole 3, the middle part of grate plate body 1 arranges several seams 2 of combing, and the cross sectional shape of each seam 2 of combing is respectively trapezoidal, and trapezoidal small end arranges chamfering 4.Should make the seam 2 trapezoidal large ends of combing towards discharge end during installation, can not be anti-loaded, the compartment grate plate mainly is subjected to extruding and the friction of abrasive body, and the power that is hit is large, so whole 1 material of grate plate adopts wear-resistant alloy cast steel.
Claims (1)
1. cement grinding mill compartment grate plate, it is characterized in that: comprise the grate plate body that adopts wear-resistant alloy cast steel to make, the two ends of grate plate body arrange respectively bolt hole, and the middle part of described grate plate body arranges several seams of combing, the cross sectional shape of each seam of combing is respectively trapezoidal, and trapezoidal small end arranges chamfering.
