Limestone milling is generally divided into limestone coarse powder processing (0 - 3MM), fine powder processing (20 mesh -400 mesh), and ultra-fine powder limestone deep processing (400 head - 1250 mesh) and micro powder processing (1250 mesh - 3250 mesh ) Four types.

The first stage: broken

Limestone large pieces of material are broken by a crusher to enter fineness (15mm-50mm) into the mill.

The second stage: flour

The crushed limestone small pieces of material are sent to the silo by the elevator, and then sent to the grinding room of the mill by the vibration feeder for uniform and quantitative grinding.

The third stage: classification

The pulverized material is graded by the classifier, and the unqualified powder is graded by the classifier and then returned to the main machine for pulverization.

The fourth stage: Set powder

Powder in line with fineness is separated and collected by air flow into the dust collector through pipelines, and the collected finished powder is sent to the finished warehouse by the conveying device through the discharge port...
