Our client from UK have ordered a 70m length scraper conveyor from SRON, today our client shared the scraper convryor picture in their workshop,and spoke highly of the quality. The success of the 70m length scraper conveyor again provced SRON technical calculation and manufacture capacity, since according to the national code, the scraper conveyor length is better no more than 80m, that means the 70m length is an extreme value in practice. After a rigorous calculation, we choose the resonable power SEW brand motor and reducer, no waste.
