Ground calcium carbonate prodction process

The production methods of heavy calcium carbonate mainly include dry method and wet method. The dry There are two main production methods of ground calcium carbonate: dry method and wet method. Dry method generally produces ground calcium below 2500 mesh. If it produces ground calcium above 2500 mesh, it is technically feasible, but it is not economically feasible due to high energy consumption and high cost. The production of superfine ground calcium carbonate above 2500 mesh is mainly done by wet grinding, while dry grinding is the first step of wet grinding.

Paper industry research report: demand recovery guides cycle deduction, the layout is at the right time

The inventory cycle is divided into four stages: (1) active replenishment: the demand recovers and the inventory turnover accelerates, the enterprise actively increases the inventory, the growth rate of operating revenue and inventory increases, and the profit of paper enterprises increases first, and then changes with the fluctuation of the prices of raw materials and finished products; (2) Passive replenishment: industrial demand falls back, the adjustment of enterprise production behavior lags behind, the growth rate of income falls back, the inventory is still rising, but will come to the end of the inventory upward stage; (3) Active destocking: with the decline of external demand, the inventory turnover rate decreases, enterprises reduce production and take the initiative to reduce the inventory level, and the inventory growth rate and income growth fall back; (4) Passive destocking: external demand has bottomed out, but enterprises still maintain a low level of production, and inventory is accelerated. Corporate revenue growth stabilized and rebounded, and inventory growth declined, which is the end of inventory decline.
