scraper conveyor stages of development

Scraper conveyor in coal production and the construction Concrete Mixing Truck has gone through three stages. The first stage 30-40 Years, is detachable scraper conveyor, it can only be a straight line in the laying face, with the face of the advancing, The need to manually disassemble, move, assemble. Scraper chain plate, mostly single-chain, such as V-type, SGD-11 type,SGD-20 type and other low-power light-duty scraper conveyors. The second stage is the early 1940s by the German manufactured flexible Scraper conveyor, Concrete block machine, metal bracket with the realization of the mechanized mining. The scraper conveyor cough Adapt to uneven floor and level uneven convex bending and other conditions, transference without disassembly, and also the amount of coal The increases, such as the prevailing model SGW-44 type scraper conveyor is this phase of the representative products. Enter 60 years Since the emergence of hydraulic support on behalf of, in order to meet the needs of mechanized mining, scraper conveyor developed to the third stage,Developed a high-power heavy armored cough curved scraper conveyor, such as SGD-630/75 type, SGD-630/180 type and so on Belong to this stage of the product.
