1. The sandstone washing operation can prevent the blockage of the mine bin, the chute, the funnel and the crushing and screening equipment, so that the processing capacity of the crushing and screening equipment is reduced, and when the blockage is serious, the production cannot be performed normally. 2, some minerals can be made useful minerals enriched by washing qualified concentrate obtained, for example, some deposition of manganese ore, apatite ore, iron oxide ore. 3, limestone can be removed by washing to improve the quality of the mine to meet the smelting requirements, such as Chuanshan limestone mine, Wulongquan limestone mine. There are many types of sand washing equipment. Commonly used are cylindrical washing machines, screen scrubbing machines, trough scrubbers, and hydraulic washing screens. In addition, various screening equipment (such as fixed strip screens, roller screens, vibrating screens, etc.) and spiral classifiers can also be used for washing. Sand and stone washing operation principle: The sandstone washing operation is a process of scrubbing the ore which is cemented by clay or contains more mud with water or mechanical force, crushing the ore, washing the fine mud on the surface of the ore and separating it. Sand mines and deeper ore levels of oxidation and weathering are necessary preparations before ore mining or beneficiation . The sand and gravel washing can avoid the muddy materials in the mud mineral raw materials blocking the crushing equipment and the screening equipment, and the raw materials containing the soluble useful or harmful components should also be washed. According to the difficulty of washing the ore in the ore, it is divided into difficult to wash, medium washable and easy to wash, mainly related to the nature, content and existence state of the clay in the ore. Washing can be carried out in a scrubber or in a screening and sorting facility . Common sand washing equipment is: 1 hydraulic washing sieve. A washing method using a water gun to rinse on a fixed strip screen for easy-washing ore. 2 tubular washing machine. Includes cylindrical screen and cylinder scrubber. The rotary screen has a high rotating speed, and the inner wall of the screen cylinder is provided with a longitudinal lifting plate, an annular baffle and a high-pressure water spraying device to improve the breaking ability and is used for easy washing ore. 3 cylinder scrubber. The cylinder is divided into two sections, the front section has no holes, which is used to soak and disintegrate the ore, and the latter section has holes for the separation of mud and stone. 4 spiral stone washing machine. It is often used for difficult to wash ore and has a strong scrubbing effect. Pre-soak the ore, set high-pressure water spray during the washing process, apply vibration, add a small amount of chemicals (such as 1% concentration of NaOH), etc., can improve the efficiency of sand washing. The efficiency of sand and gravel washing has a great influence on the beneficiation.
Tert-Butyl peroxybenzoate (TBPB) a chemical compound from the group of peresters. It is often used as a radical initiator in polymerization reactions, such as the production of LDPE from ethylene, and for crosslinking, such as for unsaturated polyester resins.
TBPB is a low volatility ,high purity,liquid, aromatic peroxuester.it is effective as medium of a broad spectrum of monomers e.g .styrene.ethylenn,acrylics.it is also used to cure (copolymerzation) unsaturated resins .
TBPB is a clear light yellow liquid, which is little soluble in water but well in many organic solvents such as ethanol or phthalate.
