1. What are the uses of gypsum powder?
Gypsum powder can be used as a raw material for concrete expansion agents, crack prevention agents, and self-leveling mortars, as well as a composite mineralizer for special cement production. By adding an appropriate amount of activator, anhydrite cement and cementitious materials can be produced, suitable for foundation reinforcement. Wall plastering, mechanical models, tunnel support, fiber pressure plates, etc. In decoration, gypsum powder is generally used for foundation treatment, such as filling joints, adjusting internal and external corners, and leveling the first layer of putty on the walls of rough rooms. Gypsum powder can also be used in industries such as building materials, chemicals, molds, food, and casting. As a well-known manufacturer in the field of gypsum grinding equipment, Hefei Hengcheng is full of confidence in the development of gypsum vertical grinding machines and continuously strives to produce high-quality gypsum vertical grinding equipment that can effectively improve the market value of gypsum and create more profits.

2. Grinding principle of gypsum powder vertical mill
The electric motor drives the grinding plate to rotate through a reducer, and the material falls into the center of the grinding plate from the feed inlet, while hot air enters the grinding chamber from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the edge of the grinding disc, and large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding disc for re grinding, and qualified fine powder is discharged with the airflow, Collect in the powder collection device, which is the product. Materials containing moisture are dried during contact with hot gases to achieve the required product moisture.

Specifications And Technical Parameters Of HVM Gypsum Vertical Mill

In terms of production and manufacturing of vertical mills, Hefei Hengcheng Industrial Equipment Technology Co., Ltd. has strong development capabilities and rigorous production processes. Each product has a strict set of factory inspection standards. For gypsum powder vertical mills, the production process of gypsum powder vertical mills is scientific and reasonable, and the design structure is advanced, making it the best choice for casting high-quality gypsum powder.

Advantages of HVM gypsum vertical mill as a production equipment for building gypsum powder:
① High efficiency of grinding and dehydration. The vertical gypsum mill uses the principle of material bed grinding to grind materials, and uses gas transportation to increase the specific surface area of the finely ground materials. It has sufficient contact with hot gases. In this thermal dynamic environment, gypsum fine powder is easily dehydrated quickly and thoroughly.
② Uniform particle grading, product three-phase (soluble anhydrous gypsum β The proportion of semi hydrated gypsum and residual dihydrate gypsum is stable. The material only stays in the mill for 2-3 minutes, while the rotary kiln or frying pan takes 10-20 minutes.
③ The process is simple and the building area is small. During the operation of the vertical gypsum mill, high-temperature hot air is introduced, and the materials are ground fine while being dehydrated and dried. Dust containing gases can directly enter the high-temperature resistant bag dust collector and be collected as products. Therefore, the process flow is simple and the layout is compact, which is about 20% to 30% of the construction area of the same production scale using rotary kilns or frying pans.
④ Low noise, low dust, high automation level, and high operation rate.
⑤ Low investment and quick results.
