5.Method and Process
(1)Dry process production process: first hand picking brought from a quarry of calcite, limestone, chalk, shells, etc., to remove the gangue; Then use crusher to coarse crushing of limestone, reoccupy Raymond (pendulum) grinding pieces get fine lime stone powder, finally with classifier to grading flour, meet the requirements of the particle size of powder as product packaging warehousing, otherwise returns mill flour again.
(2)Wet production process: first put made from dry powder suspending liquid in further grinding mill, by dehydration, drying, after making the superfine heavy calcium carbonate.
6.packing:25kg inner with plastic film bag,outer with P.P woven bag,or as your need.
7.Delivery:7-10days after received the 50% TT in advance.
8.sample:free and timely.
