Description

Flyash special efficient grinding machine
Technical field
The utility model relates to a kind of superfine powder grinding machine, is specially adapted to the cinder grinding in the flyash, can make the powder that does not reach I level, II level flyash, after this special use grinding machine processing, reaches the standard fineness of I level, II level flyash.
Technical background
At present in thermal power plant and the metallurgical smelting industry, burn coal and be still its main fuel, yet the fire coal for many years produces in the process of coal ash, coal ash has become a kind of pollution nuisance through accumulation, over past ten years, after both at home and abroad scientist makes great efforts to extract in the coal ash various metals and glass grain microballon, its a large amount of flyash fully obtains development and use, this utilization is that regeneration with good conditionsi is handled, because flyash burns from boiler after the cooling, granularity at 45 μ m between the 150 μ m, extract powder below the 45 μ m as industrial building materials materials by selecting powder processing back, yet still have a large amount of powders greater than 45 μ m need process once more levigate could be as industrial building materials materials, present domestic most enterprises all are as levigate equipment with tube mill, because the ball mill investment is big, volume is big, the energy consumption height, efficient is low, shortcomings such as floor space is big, and the big and abrasion part consumption of operating noise is big, product operating cost height, drop into also bigger, maintenance is big, and auxiliary equipment is many, so ball mill is not desirable milling equipment.Many enterprises do not have an optimistic view of powder-grinding process, cause the obstacle of the secondary fining-off of flyash, even discarded once more polluting.
The utility model content
It is even that technical problem to be solved in the utility model provides a kind of charging, and it is good to go out all neat operating mode of grind materials particle, and energy consumption is low, and the output height is pollution-free, economical and practical reliable flyash special efficient grinding machine.
For solving the problems of the technologies described above, the flyash special efficient grinding machine that the utility model provides, comprise upper machine body frame, lower body frame, main shaft, grinding roller frame, roller and main shaft lower carriage, on described upper machine body frame, be that the center circumferentially evenly is provided with batcher with described main shaft, be provided with material separating disc on the described main shaft in being in described upper machine body frame, the outlet material of described batcher drops on the described material separating disc, is that the center circumferentially evenly is provided with discharge opening with described main shaft on described main shaft lower carriage.
Described batcher is a meal lock wind metering speed governing batcher.
Described roller is dumbbell shaped roller or three pitch circle column rollers.
Described grinding roller frame is made disc and 4 or 6 or 8 kidney v notch vs is arranged, described kidney v notch v is located on the thickness direction of described grinding roller frame, staggered floor is arranged, the neck of described roller is installed in the gap portions of described kidney v notch v, described roller and lining ring contact site are big, increase mill efficiency and make the roller-way abrasion evenly.
The appearance of described upper machine body frame and lower body frame is welded with water jacket, feeds recirculated water, can effectively reduce body, lining ring temperature, prevents that liner plate from causing lining ring inefficacys of annealing too early because of bump produces high temperature, can be good at playing the effect that sound insulation is lowered the temperature simultaneously again.
Adopt the flyash special efficient grinding machine of technique scheme, motor drives main frame belt pulley main axis rotation by belt pulley, and the momentum of rotation is passed to material separating disc with main shaft and 8 secondary grinding roller framves rotate.4~8 rollers (dumbbell shaped or cylindric) have been installed on every secondary grinding roller frame equably, lining ring up and down is installed in last lower bearing bracket, under the main axis rotation state, roller is outwards dished out by centrifugal action, roller is close to lining ring and is rolled, both rotation was also revolved round the sun, because roller quantity is many, hierarchy number is many, and the probability of comminuting matter is also high, sizing, aggregation phenomenon can not appear, rationally adjust inlet amount, make it after forming the certain thickness bed of material between roller and the lining ring, promptly to have reduced the abrasion of roller and lining ring, do not produce the grinding phenomenon again, and made machine efficiency reach peak value again.Very effective decomposition glass grain microballon crumb structure, finished product ash fineness also reaches peak value.Owing on the upper machine body frame, be that the center circumferentially evenly is provided with batcher with the main shaft, charging is even, be provided with material separating disc on the main shaft in being in the upper machine body frame, material separating disc can evenly be given grinding roller frame and roller with material, be that the center circumferentially evenly is provided with discharge opening with the main shaft on the main shaft lower carriage, it is good to go out all neat operating mode of grind materials particle.
In the utility model, adopt to force impact mill crumbling method, be used in broken medium-hard material, be specially adapted to the meal fining-off of flyash.This machine efficiency height, it is good to go out all neat operating mode of grind materials particle, and reduced investment easy to maintenance has only the consumptive material 1/3 of tube mill; Power consumption is low, and is under equal milling capacity situation, more energy-conservation more than 50% than conventional tubular ball mill.Full-enclosed structure, good dustproof effect, floor space is few, has only with 1/5 of output ball mill, can substitute the tube mill in the fine break fully, also can form open circuit or closed circuit system works separately, be that a kind of adaptability is strong, handsome in appearance, the ultra-fine worn-off equipment of novel structure, efficient is tens times even hundreds of times of ball mill, reaches good effect and have better economic again on serviceability.
In sum, the utility model is a kind of ultra-fine material of medium hardness that is applicable to, be particularly suitable for the grinding machine that the flyash meal is milled, it is simple in structure, practical, long service life, cost are low, energy-conservation, consumption reduction, easy to maintenance, environmental protection, flyash special efficient grinding machine that operating mode is good.
