Coating process: production process of light calcium carbonate

Core tip: raw material, high calcium limestone (bluestone) chemical formula: CaCO3 The calcium content is 52-55, the block (4-10cm) is calcined into ash block (the calcium oxide content of the burnt ash block is 90-96), and then enters into the pulper after screening to remove the unburned core After settling in the coarse slurry tank, it enters into the medium slurry tank for sedimentation, and then it is pumped into the slag remover for slag removal The slurry after slag removal flows into the refined slurry tank, and then it is pumped into the carbonization tower by the refined slurry tank for carbonization (the compressor is used for carbonization The carbon dioxide produced in the furnace is pressed into the carbonization tower by the compressor until the mortar is carbonized to the pH value of 9-9.5 Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Paint Home News: raw materials, high calcium limestone (bluestone) chemical formula: CaCO3 The calcium content is 52-55, the block (4-10cm) is calcined into ash block (the calcium oxide content of the burnt ash block is 90-96), and then enters into the pulper after screening to remove the unburned core After settling in the coarse slurry tank, it enters into the medium slurry tank for sedimentation, and then it is pumped into the slag remover for slag removal The slurry after slag removal flows into the refined slurry tank, and then it is pumped into the carbonization tower by the refined slurry tank for carbonization (the compressor is used for carbonization The carbon dioxide produced in the furnace is pressed into the carbonization tower by the compressor until the mortar is carbonized to the pH value of 9-9.5, then the slurry can be discharged The carbonated slurry is put into the mixing tank, and then the prepared slurry flows into the slurry storage tank to pump the slurry into the high tower, which is transported to the centrifugal machine by the differential pressure for drying The dried materials are sent to the dryer for drying, and the light calcium after drying is broken by the dispersing machine before entering the vibrating screen (the mesh fineness is 120 mesh) The light calcium after screening can be bagged as finished products The fineness of the finished product reaches D97 The whiteness of the finished product is over 93 and pH value 7-9 is the best With an annual output of 50000 tons, 6-7 million investment in plant construction and equipment, the production line is highly automated There are 17-18 production personnel in each shift (60 are required for the three eight shifts of the whole plant, including management personnel) The production capacity of each shift is 50 tons, the annual output is 45000-50000 tons, and the net profit per ton is 60-80 yuan Feeding and calcining section, 3-man-made pulp and slag removal section, 2-man-made carbonization test section, 2-man pulping pool, 1-man centrifuge, 1-man (2 automatic centrifuges), feeding and drying section, 2-man finished section, 3-4 man-machine repair, 1-man electrician, coating house, focusing on coating, diatom mud, paint coating, coating technology, coating technology, fire-resistant coating news and coating, diatom mud, paint coating, coating technology, fire-resistant coating decoration Knowledge and decoration renderings,
