Lime powder is made by grinding limestone through a mill. Lime powder is widely used in the construction industry. It can be prepared into lime mortar for masonry or plastering projects, and can also be used to make building foundations, ground cushions and roads. Pavement base is an indispensable raw material in many fields.

Lime powder is commonly used in pulverizers and ball mills, but since the output particle size of the ball mill is only about 200 mesh, and its equipment investment is large, and the floor area is relatively large, the pulverizer is a better choice. The type structure occupies a small area, is low in price, low in operating costs, and the finished product can be adjusted arbitrarily between 80 mesh and 800 mesh, which can meet the needs of more users, and is especially suitable for grinding lime.

Broken stage

1: Coarse crushing

Main equipment: jaw crusher
Limestone chunks are evenly fed by the vibrating feeder through the silo, and transported to the jaw crusher for coarse crushing. After the coarse crushed material is screened by the vibrating screen, it is transported to the impact crusher by the belt conveyor.

2: medium finely crushed

Main equipment: impact crusher, sand making machine
After the coarse crushed materials transported to the impact crusher are crushed by the impact crusher, the circular vibrating screen is used to screen the crushed materials, and the larger particle materials (limestone particle size ≥ 25mm) are returned to the impact crusher for re-crushing; if more For fine products or shaping, the crushed materials are sent to the sand making machine for further crushing and shaping.

Milling stage

1. Raymond Mill

Raymond mill is a “classic” equipment in the mill industry. The number of finished products can be adjusted between 80-325. It appeared earlier, with technology precipitation, ingenious workmanship, three-dimensional structure design, small footprint and low investment. , users choose more, and the market share is quite high.

2. Vertical mill

It integrates multiple functions into one body, making the production safer and more reliable, and the production capacity more prominent and excellent. It is a comprehensive large-scale grinding equipment integrating five functions of crushing, grinding, powder selection, drying, and material transportation. item features.

The lime powder grinding production line is composed of a series of equipment. In addition to the grinding machine, the whole set of grinding production equipment also needs jaw crusher, grinding machine, bucket elevator, electromagnetic vibrating feeder, and dust collector, sorting machine, etc.
