Description
Technical field
The utility model relates to a kind of impact sand production trimmer and its wear-resisting block assemblies.
Background technique
Impact sand production trimmer is real using the mutual collision between the material to run at high speed and wear-resistant block collision and material
The crushing of existing material.The primary structure of impact sand production trimmer is as shown in Figure 1 to Figure 3, including main shaft assembly 1, impeller assembly
2, lower body branch 3, upper machine body branch 4, upper cover branch 5, hanging scaffold branch 6.The course of work is as follows: material passes through upper cover branch 5
It in into crusher and falls in hanging scaffold branch 6, then by entering high-speed rotating impeller assembly 2 among hanging scaffold branch 6, by impeller
High speed is cast away out of impeller channel after assembly 2 accelerates rapidly.What the material cast out was fallen with feed hopper surrounding first
Another part material impact is broken, then impacts on the material lining of upper machine body branch 4, impacts obliquely together after being repelled
It rebounds at the top of crusher chamber ring seat, then at the top of the chamber ring seat that is broken and changes direction and move downward.Launch from impeller channel
Material form continuous material curtain, in this way, one block of material is crushed in crusher chamber by multiple impact, friction and abrasive action.
Broken material leaves crusher chamber under the effect of gravity and enters discharging in 3 dump skip of lower body branch.Shape in upper machine body branch 4
At material lining, protect casing not by impact wear.
