First grid section installation ring stand includes the first curved support plate and the second curved support plate of parallel arrangement, and first
The circular arc direction uniform intervals of curved support plate and the second curved support plate upper edge curved support plate are disposed with several grid section installations
Hole.
The grid section rotation screens circle includes two, is the first grid section being located on the first grid section installation ring stand inner ring respectively
It rotates screens circle and the second grid section on the second grid section installation ring stand inner ring rotates screens circle.
The adjustable range for combing seam is 0 ~ 10mm.
The grid section is the frustum of a pyramid structure with eight ribs.
The fan-shaped frame material is ordinary steel, and grid section material is alloy wear-resisting cast steel.
Advantageous effect：
A kind of comb slit width degree of the utility model is adjusted grate plate and is had the advantages that relative to existing grate plate structure：
Firstth, comb well format and comb hole width, comb slit width degree tune can be voluntarily adjusted according to grinding material changes in process parameters
0 ~ 10mm of adjusting range, to adapt to the requirement of different material changes in process parameters；Thick object is advantageously reduced with stylish comb well format
The phenomenon that material and breakdown mill filter medium clogging comb hole.
Secondth, position easy to wear using replaceability is designed, special wear-resisting material can be used to position material easy to wear
Matter or special process processing, can save material cost, while can also extend the replacement cycle of a whole set of compartment grate plate and discharge grid plate.
To sum up, it can be achieved that improving production efficiency, drop can subtract the effect of consumption.
