Phosphogypsum Grinding Equipment and Application

Release date: 2022-11-14

Phosphogypsum is mainly gray-black and gray-white, with a particle size of 5 to 50 μm and a crystal water content of 20% to 25%. Phosphogypsum is a solid waste produced in the wet phosphoric acid process, and its main component is calcium sulfate dihydrate. The composition of phosphogypsum is quite complex. In addition to calcium sulfate, there are also incompletely decomposed phosphate rock, residual phosphoric acid, fluoride, acid insoluble matter, organic matter, etc. Among them, the existence of fluorine and organic matter has the greatest impact on the resource utilization of phosphogypsum.  The random discharge and accumulation of gypsum seriously damage the ecological environment, which not only pollutes groundwater resources, but also wastes land resources.

1. What is the use of phosphogypsum after processing?

Phosphogypsum has a large output, is widely used, and can be recycled and reused. The use of phosphogypsum after grinding is as follows:

(1). It can be used in the production of sulfuric acid and cement. The phosphogypsum-to-sulfuric acid co-production cement technology makes the sulfur in the phosphogypsum regenerate into sulfuric acid, and other components form cement clinker;

(2). Can be used as cement retarder. Phosphogypsum is used alone or mixed with dihydrate gypsum in an appropriate proportion as a cement retarder. The performance of the prepared cement is equivalent to that of natural gypsum, but the dosage is lower than that of natural gypsum, which can reduce the cost of cement production;

(3). It can be used for the production of chemical raw materials. Phosphogypsum is rich in calcium and sulfur resources, which can be commercialized through certain production processes.

2. Selection of phosphogypsum grinding equipment

A vertical mill is recommended for phosphogypsum grinding equipment. Guilin Hongcheng has pioneered research and development of a drying and grinding system based on the development trend of the industry, aiming at the bottleneck of traditional mills with low output, high energy consumption and high maintenance costs. The HLM vertical mill, which integrates grading, grading and conveying, has set off a frenzy of imitation in the field of large-scale milling, and has become the mainstream equipment in the field of coal, cement, slag, and non-metallic ore milling.
