Problems solved by technology

At present, some well-known professional crusher manufacturers in the world generally adopt the structure in which the full width of the single grate bar runs through the grate frame. The grate bar of this structure is easy to be damaged. Once damaged, it is difficult to guarantee the particle size of the product. products are difficult
At the same time, the processing of this kind of grate is difficult, and the requirements for materials are also high.

Embodiment Construction

[0009] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0010] see figure 1 and figure 2 , a grate plate with integral casting and a grate bar and a grate slot, in the vertical direction of the grate slot 1C formed between the grate bar 1B and the grate bar 1B, there are semicircular concave teeth arranged in an orderly shape 1A.

[0011] The working principle of the present invention is that when the material flow is between the grate and the rotor, since the grate plate is cast with regular semicircular concave teeth in the transverse direction, the chance of the material being hit between the grate and the rotor is increased, and part of the material is here The area is further crushed and then discharged from the grate slot. Compared with other types of discharge grates, this kind of grate...

Abstract

The present invention relates to integrally cast grate plate. The integrally cast grate plate has grate bars, grate slots and semi-circular concave teeth perpendicular to the grate slots. The present invention has grinding function and smooth material discharge for subsequent grinding, long service life and convenient maintenance and repair.

Description

technical field [0001] The invention relates to crushing equipment for medium-hard brittle materials, in particular to an integrally cast grate plate used in a single-stage hammer crusher. Background technique [0002] The single-stage hammer crusher is a crusher with a large crushing ratio. It is mainly used for crushing raw materials for cement production. It can crush the raw ore from the quarry to the required particle size for grinding. For the single-stage hammer crusher, while ensuring the production capacity, how to obtain finer products to reduce the power consumption of subsequent grinding is a technical problem. At present, some well-known professional crusher manufacturers in the world generally adopt the structure in which the full width of the single grate bar runs through the grate frame. The grate bar of this structure is easy to be damaged. Once damaged, it is difficult to guarantee the particle size of the product. products are difficult. At the same time...
