Abstract
The utility model belongs to special equipment used for agglomerate secondary crushing in metallurgical industry, which comprises a rack (10), wherein the rack (10) is installed with a motor (1), a speed reducer (2), a fixed roller device (3), a movable roller device (4) and a gear chain plate mechanism (5); and the key technical points are: the external teeth (7) of tooth rings assembling the fixed roller device (3) and the movable roller device (4) are axe-shaped, and a reinforcing rib (8) is arranged between the two teeth at the root. The crushing of the mineral-crushing machine on the material is changed to shearing crushing of the cutter teeth from the original extrusion crushing, thereby significantly reducing the content of powder in the discharge materials (capable of being less than 10%), being capable of better controlling the granularity uniformity and size of the crushed material, improving the agglomerate quality and reducing energy consumption.
Description
Affiliated technical field
The utility model belongs to plant equipment manufacturing field in the metallurgy industry, particularly a kind of sintering deposit second-time breakage special equipment.
Technical background
At present, the most of disintegrating machine of different structures such as jaw crusher, wolf's fang kibbler roll, model that adopts of sintering deposit second-time breakage carries out fragmentation, the material content of powder does not reach the requirement of blast furnace fine fodder technology to sintering deposit second-time breakage material " only ", " little ", " all " up to more than 30% after the sintering deposit second-time breakage.The granularity of powder is directly connected to the gas permeability of sinter mixture, and granularity is too big, though bed permeability has been got well, vertical sintering speed is fast, and the time compole abundant inadequately or under molten condition that liquid phase is generated is short; Too small powder size needs once more sintering to cause sinter quality to descend as returning charge, and energy consumption increases.Because the present sintering deposit recursher that uses, after the sintering deposit second-time breakage, cause material overbreak, content of powder too much, cause that quantity of return mines is excessive, energy consumption increases, cause very big waste.
Summary of the invention
The purpose of this utility model is a kind of uniformity that can improve the sintering deposit second-time breakage of design, guarantees the granularity of material, can reduces the discaling roll breaker that has cutter axe shape tooth of discharging content of powder in the material again.
The purpose of this utility model is achieved in that and includes frame, motor, reductor, stationary roll device, movable roll device, gear carrier bar mechanism, spring buffer mechanism are installed on frame, its technical essential is: the teeth circle external tooth that is assembled into stationary roll device and movable roll device is a cutter axe shape, has reinforcement between two teeth at tooth root place and forms.
When motor via reducer, transmission connecting mechanism drive stationary roll, movable roll and do relative differential rotation, staggered cutter axe shape teeth are carried out fragmentation with material shearing, splitting fragmentation, through shearing, the sintering deposit of splitting fragmentation can reach that the raw meal particle size diameter requires, epigranular, and the effect that the undersized content of powder is few

Among the figure: the 1-motor; The 2-reductor; 3-stationary roll device; 4-movable roll device; 5-gear carrier bar mechanism; 6-teeth circle; The 7-external tooth; The strong muscle of 8-; The 9-hood; The 10-frame.
The specific embodiment
The utility model is described in further detail in conjunction with the accompanying drawings.Motor 1, reductor 2, stationary roll device 3, movable roll device 4, gear carrier bar mechanism 5, spring buffer mechanism etc. are installed on frame 10, wherein, motor 1 drives stationary roll device 3 by reductor 2 and rotates, stationary roll device 3 drives movable roll device 4 through gear carrier bar mechanism 5 and rotates, movable roll device 4 is connected by gear carrier bar mechanism 5 with stationary roll device 3, can guarantee that two rollers system rotates by design velocity ratio, and two roller adjustable gaps joint.Movable roll device 4 is installed in the sliding tray, and give and certain prestressing force by spring buffer mechanism, and regulate gap between stationary roll device 3 and the movable roll device 4 by adjusting bolt or other governor motions, size with the control particle size after cracking, stationary roll device 3 and movable roll device 4 are a plurality of teeth circles 6 compositions are installed in rotating shaft, the external tooth 7 of teeth circle 6 is a cutter axe shape, has reinforcement 8 between two teeth at tooth root place.In order to prevent splashing of broken thing and flying upward of dust, stationary roll device 3 and movable roll device 4 are installed in the hood 9.
Because this broken ore deposit machine is to the fragmentation of material, become the shearing-crushing of cutter tooth by original attrition crushing to material, thereby significantly reduce the content of discharging powder in the material (can less than 10%), and can control the granule size and the uniformity of the thing that is broken preferably, improve the quality of sintering deposit well, reduce energy consumption, for metallurgy industry provides a kind of disintegrating apparatus well.
Claims (1)
1. two rollers break the ore deposit machine, include frame (10), motor (1), reductor (2), stationary roll device (3), movable roll device (4), gear carrier bar mechanism (5), spring buffer mechanism are installed on frame (10), it is characterized in that: the teeth circle external tooth (7) that is assembled into stationary roll device (3) and movable roll device (4) is a cutter axe shape, has reinforcement (8) between two teeth at tooth root place and constitutes.
