PT Semen Padang conducts Silica and Limestone mining business in Bukit Karang Putih, Indarung, Lubuk Kilangan District, Padang City. In mining at PT Semen Padang there is a conveying activity in which in this activity the transportation of material that has been crushed is transported to storage. There are many types of storage for Padang Cement, starting from Indarung II, III, IV, V and VI. In conveying activities at Semen Padang there are 2 lines, namely the old line and the new line which is called the longbelt. At PT Semen Padang, belt conveyors come in a variety of sizes, and depending on the route taken for delivery, the capacity of each belt for the delivery of raw materials varies. As a result, the minimum production capacity will determine the belt conveyor's production capacity.
