First grid section installation ring stand includes the first curved support plate and the second curved support plate of parallel arrangement, and first
Arcuately the circular arc direction uniform intervals of supporting plate are disposed with some grid section installations on curved support plate and the second curved support plate
Hole.
The grid section rotation screens circle includes two, is the first grid section on the first grid section installation ring stand inner ring respectively
Rotate 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.
Described fan-shaped framework material is ordinary steel, and grid section material is alloy wear-resisting cast steel.
Beneficial effect：
A kind of adjustable combination grate plate of comb slit width degree of the present invention has the advantages that relative to existing grate plate structure：
Firstth, comb well format and comb hole width can be voluntarily adjusted according to grinding material changes in process parameters, seam width adjusting model of combing
0 ~ 10mm is enclosed, to adapt to the requirement of different material changes in process parameters；With stylish comb well format advantageously reduce thick material and
The phenomenon in breakdown mill filter medium clogging comb hole.
Secondth, position easy to wear is designed using replaceability, can to position material easy to wear using special wear-resistant material 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.It is comprehensive
On, it can be achieved to improve production efficiency, drop can subtract the effect of consumption.
