In the redirection roller scraper device. At the redirection roller conveyor belt along the scraper set, eliminate redirection roller material bonding problem and solve the local damage caused by roller sticky material conveyor belt. Conveyor head, tail and intermediate transfer transition of improvement. Conveyor head, tail and reproduced in the transition length and the transition way among them, a great influence on the service life of the conveyor belt. Must to design a reasonable transition, should try to reduce wear on the surface of the rubber conveyor belt, and make sure no conveyor belt fold, middle bump phenomenon, blanking of a material not leakage. Conveyor at the concave transition pressure pulley. Carry out a proof, steel cable conveyor belt transverse strength is insufficient, startup, conveyor belt pulley cause local force is too large, lead to tear conveyor belt, brings pressure all round instead of pressure roller, can thoroughly solve the problem. Big lightening of balancing machine boom conveyor belt. Coal yard stacker system boom conveyor belt service life is very short, originally under the heavy weight design is a conveyor belt tension is too large, cracked aging prematurely. In heat resistant conveyor belt tension on the basis of carrier material, reduce weight, to extend service life in delivery of coal by 1.5 million t 4.5 million t. Material piling and taking machine 200000 t mine system counterweight boom conveyor belt the original design of 25 t (including counterweight roller weight), original German import tensile steel wire with homework in less than 3 million t serious stretch scrap, after twice weight lightening reduce 6 t, domestic ordinary steel wire belt, down more than 8 million t.
