Embodiment Construction

[0030] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to embodiments and drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0031] Such as figure 1 with figure 2 As shown together, a classification treatment cycle system for the production of heavy calcium carbonate and a classification treatment cycle system for the production of heavy calcium carbonate are arranged in sequence according to the direction of the raw materials with a raw material tank 1, a batching tank 2, a wet mill 3, and a cyclone Device 4, finished slurry tank 5, centrifuge 6, dryer 7 and finished product tank 8.

[0032] The raw material tank 1 is connected to the batching tank 2 through a screw conveyor, a wet mill buffer tank 9 is also arranged between the ba...

Abstract

The invention discloses a grading treatment circulating system for producing ground calcium carbonate. A raw material tank, a burdening tank, a wet mill, a cyclone, a finished pulp tank, a centrifugalmachine, a drying machine and a finished product tank are sequentially arranged in the raw material direction. The cyclone is a hydrocyclone. The hydrocyclone further comprises an overflow opening and an underflow opening. The underflow opening communicates with a recovery barrel. The recovery barrel is of a cylinder structure and is provided with a coarse material outlet. The overflow opening communicates with a division barrel. The division barrel is of a cylinder structure and is provided with a pulp outlet. The pulp outlet communicates with the finished pulp tank through a pipeline. The coarse material outlet communicates with a feeding opening of the wet mill through a pipeline. According to the circulating system, the pulp grading process is achieved, the problem that wet-milling pulp cannot be graded in domestic is remedied, the product particle size distribution is quite narrow, and the product fineness is more uniform.

Description

Technical field [0001] The invention relates to the technical field of heavy calcium carbonate production equipment, in particular to a grading treatment cycle system for producing heavy calcium carbonate. Background technique [0002] Calcium carbonate is generally divided into heavy calcium carbonate and light calcium carbonate. Heavy calcium carbonate, also known as ground calcium carbonate, or heavy calcium for short, is prepared by physical processing methods; light calcium carbonate, also known as precipitated calcium carbonate, or light calcium for short, is prepared by chemical processing methods. Heavy calcium carbonate is a calcium carbonate product obtained by physical methods. Generally, high-purity limestone (such as calcite, chalk, etc.) is used for grinding. The density of heavy calcium carbonate is heavier than that of light calcium carbonate, and the sedimentation volume is larger. low. [0003] The production system of heavy calcium carbonate is divided into dry...
