Description
Technical field
Metal cutting apparatus is the utility model is related to, specifically a kind of live milling attachment of sintering mixer backing ring.
Background technology
Iron-smelter sintering uses mixer at present, and trommel mixer is one of visual plant in sintering, pelletizing system.It can use
In multiple uses such as raw material mixing, granulation, rolling coals, meet requirement of the sintering machine to raw material.The drive mechanism master of trommel mixer
By gear and gear ring engaged transmission backing ring is supported by 4 carrying rollers.Trommel mixer is provided with 1.5 ° of -4 ° of angles of inclination, makes cylinder
Body feeding mouth and discharge port center produce difference in height, material while mixing by material gravity component effect and constantly to
Preceding motion.Whole cylinder is seated on front and rear two groups of riding wheel apparatus, can freely be rotated.In preceding support roller group（Positioned at delivery end）Base
Gear wheel, gear wheel and rolling ring contacts side surfaces are housed on plinth seat, bear cylinder sliding force, constrain cylinder axial float.Transmission device
On the foundation base of cylinder side, nibbling platform by the bull gear on drive pinion and barrel device makes barrel body rotation.Cylinder
The course of work of mixer is that belt conveyor constantly inputs compound in cylinder directly or by batch meter, with circle
Cylinder rotates, in cylinder compound be continuously brought to certain altitude it is backward under leave rolling, and moved forward along cylinder, formation spiral
Shape moves, and from first to last, through multiple circulation, completes mixing, granulation and adds water in right amount, then reach afterbody and discharged through chute.It is mixed
Conjunction machine has very important status in the preparatory stage of whole raw materials for sintering, once mixer breaks down, by direct shadow
Sintering machine is rung to shut down.

Roller lifts, and then dismantles motor, reductor, the auxiliary device such as jacket, hoisting transportation to maintenance factory, maintenance factory's built-up welding,
The flows such as heat treatment, turning, modifier treatment, transported back after reaching technical requirements, equipment is reinstalled（4 carrying rollers of first positioning adjustment
And top wheel, then mounting rotary drum and centering, finally recover shield installation motor reducer）, last commissioning device, recover factory building knot
Structure.
Chinese utility model patent 201410666658.6 discloses《A kind of field turning device of steam roaster rolling ring
And its method for turning》, it can equally handle the problem of mixer shakes, but it has the following disadvantages：
Turning is continuous turning, larger to motor load.
Turnery processing is hilted broadsword head operation, is unfavorable for cutter head cooling, and the consumption to cutter head is larger.
Turnery processing can only process plane, it is impossible to process inclined-plane and vertical plane, the range of work is smaller.
