Problems solved by technology

However, in the preparation process, the mined raw ore was not screened, and all the mined raw ore were crushed step by step, which caused some small-sized raw ore to fail to crush during the primary or secondary crushing. , thereby increasing the energy consumption of production and reducing the efficiency of production
The current gypsum ore is not preheated before calcination, so it needs to consume a lot of energy during calcination, thus increasing the cost of production

Abstract

The invention discloses a gypsum powder preparation process and system. The system comprises a conveying device, a jaw crusher, a hammer crusher, a feeding device, a rotary kiln calcining pot and a centrifugal pulverizer which are arranged in sequence, wherein the conveying device comprises a primary conveyer belt, a secondary conveyer belt and a third conveyer belt; discharge baffle plates are correspondingly mounted on the primary conveyer belt, the second conveyer belt and the third conveyer belt; a primary collecting plate which communicates with the jaw crusher, a secondary collecting plate which communicates with the hammer crusher and a third collecting plate which communicates with the feeding device are additionally arranged on a rack; a waste heat channel is formed between the feeding device and the rotary kiln calcining pot; and the centrifugal pulverizer is connected with a storage tank. As ores are graded in a conveying process, energy consumption for continuously crushingthe ores can be reduced, and the ore crushing efficiency can be improved; and in addition, due to adoption of the waste heat channel and a novel centrifugal pulverizing component, the product qualitycan be further improved, and the energy consumption cost for production can be lowered.

Description

technical field [0001] The invention belongs to the technical field of gypsum powder preparation, and in particular relates to a gypsum powder preparation process and system. Background technique [0002] Gypsum powder, whose main component is calcium sulfate, includes natural gypsum and industrial gypsum. Among them, industrial gypsum, also known as industrial by-product gypsum, is a by-product of some industrial production processes, mainly including phosphogypsum and desulfurization gypsum, of which phosphogypsum accounts for more than half of industrial by-product gypsum. The main component of industrial gypsum is dihydrate gypsum, which is an excellent raw material for the production of building materials and the basic raw material for the production of gypsum blocks, gypsum bricks, gypsum boards, gypsum wallboards, and plastering gypsum. To produce good gypsum products, first of all, the industrial by-product gypsum, dihydrate gypsum, must be dried and calcined into q...
