Summary of the invention

The purpose of this utility model provides a kind of three novel discaling roll Sizing Crusher, it has reduced the body height with respect to the kibbler roll of two-stage up and down, be beneficial to installation and maintenance, and broken discaling roll will be lacked relatively, rigidity and intensity, cloth effect also will be got well, total is concentrated compact, helps transportation, installs, debugs and safeguards.

The technical solution of the utility model is as follows: a kind of three discaling roll Sizing Crusher, form by frame, power set, breaker, charging and discharging mouth, casing, power set drive the breaker motion, it is characterized in that described breaker breaks tooth plate by three discaling rolls and a limit and forms, wherein two discaling rolls move relatively and form the broken operative minor of one-level, the broken tooth plate in another discaling roll and described limit forms the broken operative minor of not outer one-level, and the broken operative minor of described two-stage is on a horizontal plane.

The broken operative minor of one-level that described two discaling rolls move formation relatively can be driven by cover power set and set of gears transmission device, and the 3rd discaling roll drives with cover power set separately.

Each is all driven described three discaling rolls by cover power set.

Also be provided with two classification tooth plates on the described three discaling roll Sizing Crusher, described classification tooth plate is corresponding with the broken work of two-stage parafacies respectively, makes material after the fragmentation through classification tooth plate, separation of material.

Adopt three discaling roll Sizing Crusher of this mode, owing to be the mode of the combination fragmentation that intensifies of being marred by a scar, etc. of broken and limit wall with the centre, leak down by slit classification between classification tooth plate and the pair roller through qualified little material after the one-level fragmentation, big grain material finally reaches the broken requirement of material along with the discaling roll motion is broken or the limit wall is broken in the middle of participating in once more.This disintegrating machine is the disintegrating machine of two-stage relatively up and down, and the body height is less, is beneficial to installation and maintenance; Its length is 2/3rds of identical tonnage two rod-toothed crusher length basically, and overall width is that two rod-toothed crusher width add a discaling roll diameter and add classification tooth plate wall thickness basically; Because broken discaling roll will be lacked relatively, rigidity and intensity, cloth effect also will be got well, and total is concentrated compact, help transportation, installation, debugging and maintenance.
