Anthracite Vertical Mill with above structure, the course of work are as follows:
The millstone device 11 for being mounted on 14 top of speed reducer is driven to rotate by main motor 15, while hot wind is vertical from the entrance of hot-air mouth 17
In mill, material falls in the center of millstone device 11 of rotation from feeding inlet, and material is to 11 side of millstone device under the influence of centrifugal force
Edge is mobile, and material is rolled and crushed by Burnisher apparatus 7, continue it is mobile to 11 edge of millstone device, at by vane
Air-flow takes up, and bulky grain falls directly on millstone device 11 grinding again, when the material in air-flow passes through powder concentrator 8, coarse powder returns
Grinding again is fallen on millstone device 11, fine powder goes out to grind, collect in the dust arrester installation of system with air-flow.In the object of feeding
In material, it might have some material blocks for being difficult to crush and metal block accidentally fed in mill；Collet, which is crossed, when them reaches wind
When at ring, the air-flow for being not enough to be ejected is blown afloat, thus falls to hopper 12 along wind deflector, is scraped at dreg discharging box 16 by scraper plate
Discharge.
Anthracite Vertical Mill, is designed using micro-positive pressure described in the present embodiment, and can effectively mill anthracite；It is being ground using grinding roller
Ground material is directly rolled on disk, low energy consumption；It can change the size of grinding forces, by way of hydraulic loaded so as to increase
Big yield improves milling efficiency；Hydraulic system operation mill running is more stable, auto lifting roller and can fall roller, it can be achieved that empty (light)
It carries and starts, high safety and reliability；The setting of mechanical stop limiter guarantees to keep certain distance between grinding roller and mill, avoid resistance to
Grind the friction and collision between part and metal parts；By water injector, can the effectively stable bed of material, keep grinding machine more safety steady
Fixed operation；Cleaning wind system is devised, solves the problems, such as material accumulation；Sound Studies of Packaged Rotary Seper ators (selects powder
Machine) grinding efficiency height；It is equipped with and turns over roller arrangement, grinding roller can be routed up outside mill, easy access.
The above is only that preferred embodiments of the present invention will be described, is limited the scope of the present invention
It is fixed；The foregoing is merely a specific embodiment of the invention, are not intended to limit the scope of protection of the present invention；It is not departing from
Under the premise of design spirit of the present invention, this field ordinary engineering and technical personnel any is repaired to what technical solution of the present invention was made
Change, equivalent replacement, improvement etc., should fall within the scope of protection determined by the claims of the present invention.
