Scraper conveyor (scraper) application materials and use environment
The scraper conveyor can be used for horizontal transportation or inclined transportation. The inclination angle of the coal seam shall not exceed 25° when transporting along a slope, and the inclination angle shall not exceed 20° when transporting downwards. When the inclination angle of the coal seam is large, anti-skid devices should be installed. The bendable scraper conveyor allows 2°～4° bends in the horizontal and vertical directions.
The working principle of the scraper conveyor is to use the open chute as a bearing part for coal, gangue or materials, and fix the scraper on the chain (to form a scraper chain) as a traction member. When the driving part of the machine head starts, the sprocket on the driving head shaft rotates, so that the scraper chain circulates and moves the animal material along the chute until it is unloaded at the machine head. The scraper chain bypasses the sprocket and runs in a stepless closed loop to complete the transportation of materials.
Coal powder, crushed coal, soot, carbon black, ammonium bicarbonate, pyrite powder, ammonium chloride, copper concentrate powder, alumina powder, gypsum powder, limestone powder, soda powder, urea, activated carbon, sodium chloride, Calcium silicate, asbestos powder, synthetic resin, rubber powder, calcium carbide, clay, synthetic fertilizer, powdered pesticides, barium ammonium sulfate, soda ash powder, granular medicine, wheat, soybeans, rice, sugar, starch, crushed charcoal, wood chips, Sawdust, vinyl chloride alcohol synthetic detergent, fly ash phosphate fertilizer, etc.
For scraper conveyors, the bulk density r of the conveyed materials is generally less than 1.0. The general-purpose scraper conveyor is not suitable for conveying high temperature, toxic, explosive, flammable, abrasive, corrosive, highly adhesive, highly suspended, and particularly fluid , Hard and brittle materials that do not want to be broken. When the scraper conveyor is needed for materials with these characteristics, it can be designed as special models such as high temperature resistant, corrosion resistant, wear resistant, fully airtight and explosion-proof.
