The R&D team at Hosch has identified that there is a demand in the bulk material handling industry, for a system that addresses the dangerous issues caused by spillage at the loading point of a conveyor system. The new Hosch conveyor skirt system FD has been designed to address these issues.
Spillage typically occurs due to material overflow, asymmetric feeding, bouncing material and air borne particles. This creates a highly dangerous work environment for employees, potential loss of material, damage to the plant and environmental problems.
The new Hosch conveyor skirt system is a reliable unit that will prevent spillage around the loading point and ultimately eliminating the dangerous issues caused by spillage. Each skirt system has sealing boards that are stainless steel or galvanised steel option. Each skirt board is equipped with rubber sealing blocks that can be adjusted to form a seal with the belt and individually adjusted to increase sealing efficiency. In order to achieve maximum sealing efficiency or as the blocks wear with minimum wear the sealing blocks must be in light contact with the belt.
The Hosch R&D team conducted one of their trials of the FD system on several belts at the RWE Power Plant Ville in Germany. This particular plant is an old lignite-fired power plant and is sometimes used to provide steam for the paper industry and lignite block pressing facilities. Occasionally wooden refuse is added to the lignite in order to increase the efficiency. Due to the age of the plant the conveyors have varied belt widths. To make sure that the material is conveyed properly the small belts have continuous covers and the belt speeds have been increased.
The results of these trial installations have been very successful and the client RWE Power Plant Ville was very satisfied as the cost for these systems are minimal compared to the upgrade of the complete conveyors, which otherwise would be required.
