Highly wear-resistant rubber hoses, specially designed for river sand mining, mine slag removal, and dredging projects, are core components for sand pumps and mud pumps used to transport sand, gravel, slurry, and silt. They are wear-resistant and durable, with a service life far exceeding that of ordinary rubber hoses. Widely used in river sand dredging, mine slag removal, dredging projects, and tailings transportation in Africa, they are a cost-effective choice for transporting sand and slurry in sand dredging operations.
