The calcium carbonate is a tasteless and odorless white solid. It’s the important material, and widely used for many industries. According to the different producing method, it can be divided into heavy calcium carbonate and light calcium carbonate. For filter press in chemical industry, there are lots of filter press types. However, our chemical engineering filter press is best suitable for it.
The calcium carbonate produce method includes physical method and the chemical method. Generally, the heavy calcium carbonate has big specific gravity, so it usually use the physical method to produce. And the light calcium carbonate is made by chemical method, and the chemical method includes carbonization method and the precipitate reflect method. It uses limestone calcination or uses the calcium chloride reflecting with the carbonate to produce the calcium carbonate, then it’s through washing, dewatering, drying and collection to get the final product.
For the dewatering, our chemical filter press has important effect. Because the filter press has good filtering performance and the best filtering effect. Using the filter press to dewater, the filtrate will be reused for next cycle. Then the filter cakes will be dried and packed. If you want to know more info on China filter press, pls contact us.
