The use rate of limestone in industry is very high. The processed limestone powder can be formulated into lime paste, lime water, lime pulp, etc. In addition, it can also be used as coatings, adhesives, etc. in the construction industry. Since limestone powder has so many functions, what is the production process of lime powder?What equipment is needed?Here to answer for you：

What equipment is needed for lime powder production?

1 crusher

Crushing is the forefront stage of limestone production. First, a jaw crusher is used to roughly crush large pieces of material into small pieces, and then counterattack is used to break it into smaller particles again.

2 grinder

There are many grinding equipment on the market that can grind stone ash powder, but it is recommended to choose a Raymond mill. The discharge particle size of the Raymond mill is between 80-325 mesh, and there are many types of ore that can be broken, which can fully meet the production needs of most customers. In addition, it adopts a three-dimensional structure and occupies a small area. It can form an independent production system with smooth operation and low cost. Moreover, its operation is environmentally friendly and up to standard!

Limestone powder production process

1. Crushing: Large pieces of limestone are fed into the jaw crusher for rough crushing through a vibrating feeder, and then evenly sent to the silo from the bottom up by the bucket elevator.；

2. Grinding: The limestone debris in the silo evenly enters the Raymond mill for grinding and processing, and the user can adjust the fineness of the discharge powder as needed.；

3. Powder selection: The fine material after grinding is graded and sieved by the powder separator, and the unqualified fine powder must be returned to the mill for re-grinding.；

4. Packaging: After the powder is selected, the qualified limestone powder enters the storage silo through the pipeline device, and can be uniformly packed by the powder tanker.

What are the uses of limestone powder after milling?

Limestone is ground by a limestone mill to prepare limestone powder. Limestone powder has a wide range of uses according to different specifications.：

1．Single flying powder: Used in the production of anhydrous calcium chloride, it is an auxiliary raw material for the production of sodium dechromate.The main raw materials for glass and cement production.In addition, it is also used in building materials and poultry feed.

2．Shuangfei powder: It is a raw material for the production of anhydrous calcium chloride and glass, a white filler for rubber and paint, and building materials.

3．Sanfei powder: Used as a filler for plastics, paint putty, paint, plywood and paint.

4．Sifei powder: used as a filler for wire insulation, rubber molded products, and asphalt linoleum.
