Description
Technical field:
The utility model relates to the special-purpose ball mill of a kind of water-coal-slurry.Be applicable to grinding of water-coal-slurry.
Background technology:
Traditional ball mill divides two kinds of dry method mill and wet grinding mills.Dry method mill is fit to the grinding of moisture content less than 2% material.Wet grinding mill is fit to the grinding of moisture content greater than 60% powder.Because water-coal-slurry is to stir the liquid fuel of making by about 70% coal, about 30% water and dispersant.Be as required coal dust, water and dispersant feed to be pulverized the netted slurry of making to ball mill grinding by screw(-type) feeder.Water-coal-slurry through adding dispersant is coal, the water fluid-mixing with higher concentration, viscosity higher, and is mobile relatively poor, and certain deposition efficiency and size distribution requirement are arranged again.As adopt traditional ball mill then material be not easy turnover, easily stop up sieve aperture, grinding effect is poor, grinding and screening efficiency are low.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of grinding effect is good, grinding and the high special-purpose ball mill of water-coal-slurry of screening efficiency.
The purpose of this utility model is achieved in that the special-purpose ball mill of a kind of water-coal-slurry, comprise bearing, feed end slide shoe bearing seat, discharge end slide shoe bearing seat, revolving drum and edge transmission device, feed end slide shoe bearing seat, discharge end slide shoe bearing seat is forward and backward is installed on the bearing, the revolving drum two ends are installed on respectively on feed end slide shoe bearing seat, the discharge end slide shoe bearing seat, and the edge transmission device links to each other with revolving drum.
Above-mentioned revolving drum comprises cylindrical shell, shell liner, charging aperture, compartment grate plate, discharging grate plate and discharging opening, shell liner is lining on the cylinder inboard wall face again, the compartment grate plate is laterally in placing cylindrical shell, with forward and backward corase grind storehouse and the fine grinding storehouse of being separated into of feed bin in the cylindrical shell, charging aperture is arranged at barrel front end, discharging opening is arranged at cylinder back-end, and the discharging grate plate is laterally in the cylindrical shell that places the discharging opening front side.
Above-mentioned shell liner comprises rubber lining and press strip, and rubber lining is lining on the cylinder inboard wall face again, and press strip is stepped to be embedded on the rubber lining internal face.
Above-mentioned compartment grate plate, discharging grate plate comprise sieve plate, blind plate, center grid and header board gripper shoe, and the center grid is arranged at header board gripper shoe center, sieve plate, the forward and backward header board gripper shoe outside, the centering grid periphery of being connected in of blind plate.
Operation principle:
Material is by the corase grind storehouse of the spiral in the feed arrangement in charging aperture is forced the feeding ball mill barrel, material obtains pulverizing under the effect of the bigger abrasive body of average diameter (steel ball) impact grinding, be crushed to the material of certain particle size, enter in the header board gripper shoe before the blind plate by compartment grate plate sieve plate, enter the fine grinding storehouse by getting rid of in the gripper shoe again to the center grid.Material is further ground by little abrasive body in the fine grinding storehouse, and the fine powder that reaches the fine grinding requirement enters drawing mechanism by discharging grate plate, discharging opening and is discharged from, and levigate abrasive body remnants are produced by the revolution screen drum in the drawing mechanism.
The utlity model has following characteristics:
1, the slide shoe bearing supporting is adopted at this machine two ends, can be axially when making the ball mill revolution, radially positioning automatically, and the revolution stationarity is good.
2, this grinding machine divides two storehouses, all uses the staged rubber lining, forms the helical form material casting, more helps flowing of material, makes material time of staying in mill chamber long, can reach the size distribution requirement of water-coal-slurry after grinding.Therefore grinding effect is good.
3, novel combination type compartment grate plate and discharging grate plate are forced the material casting discharge, have improved grinding and screening efficiency.
4, this machine adopts monolateral pair of transmission, stable drive.
