New SGB-420/30T scraper conveyor mine explosion scraper conveyor conveyor scraper conveyors manufacturers scraper conveyor for coal mining, chemical mines, metal mines and power plants and other means of transport used to transport important materials. It is composed of central trough, chain, scraper and traction system. Among them, the middle groove is a major part of the scraper conveyor, steel central trough nearly a hundred years of history, in the long course of the following disadvantages: ① weight, installation and removal time consuming; ② central trough is generally by the 6 ~ 15mm of steel plate, when subjected to greater impact deformation, repair more difficult; ③ poor corrosion resistance; ④ poor wear resistance; ⑤ materials and Central trough friction coefficient, power scraper conveyor partially depleted in friction materials and central trough, resulting in excessive power consumption, increased investment.

The scraper conveyor cough adapt and level uneven floor uneven convex bending and other conditions, transference without disassembly, and coal volume also increased, as the prevailing model SGW-44 type scraper conveyor is at this stage representative products. Since the 1960's the emergence of hydraulic support, 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, etc. belong to this stage of the product.
