  • How to Conduct Right Maintenance for the Sludge Thickener

    Sludge thickener is the most widely used equipment in the mineral processing plant, in which every concentration and dewatering process need sludge thickeners. However, during the actual operation process, the failure rate of sludge thickener can reach 37%, so in order to reduce the failure rate of sludge thickener, daily maintenance is the key

    Thickening is the first step of sludge treatment which is used to increase the content of sludge solids by removing a portion of the liquid fraction. It is useful for further processing, namely to reduce the capacity of the tank and the equipment needed, the amount of chemicals required for conditioning the sludge, and the amount of heat/fuel needed by the digester/heat drying.
