Limestone grinding mill production line

The limestone grinding mill’s production line equipment includes a jaw crusher/cone crusher, Raymond mill (host part), bucket elevator, electromagnetic vibrating feeder, powder selector, pipeline device, etc. The specific process flow is as follows:


1. Crushing the limestone

Firstly, the jaw crusher preliminarily crushes the quarried large limestone, then sends it to the cone crusher for further fine-crushing. The two crushing stages are chosen to fully dissociate the valuable substances in the raw ore and provide high-quality ore raw materials for the milling stage.

2. Grinding limestone to powder

Next, the crushed limestone is transported to the silo from the bottom upward by bucket elevator and then uniformly and quantitatively fed into the limestone grinding mill for deep grinding processing via an electromagnetic vibrating feeder.

3. Powder selection

Finally, the limestone powder, after grinding, will be classified through the powder selector, the fine powder that does not meet the fineness requirements will be sent back to the host machine for regrinding, and the limestone powder that meets the fineness requirements will be fed into the finished product silo through the pipeline device, and finally packaged the powder to bags.

Limestone grinding machine maintenance

  1. The limestone grinding machine’s spindle refueling time is once per shift, but it must pay attention to find that the oil in the oil cup, with no loss or loss, is too slow and should immediately clean the oil channel.
  2. Strictly prohibit metal blocks into the limestone mill; otherwise, it will damage the grinding rollers, rings, and hangers.
  3. Add material should be uniform, not more or less. Adding too much material will block the air duct, reduce the output, and make it easy to burn the motor.
  4. Air volume adjustment: located in the fan inlet pipe on the air volume control valve, generally open to a slightly more prominent position, according to the fineness, the output requirements of appropriate adjustment.
  5. Fineness adjustment: according to the size of the material, hardness and softness, water content, and specific gravity are different; the processing of coarse and fine degree is also other; you can adjust the upper analyzer, high speed, high fineness.
  6. The end-of-life limit of mill rollers and rings is that the remaining small wall thickness shall not exceed 10mm.
  7. When stopping, first stop feeding, the host continues to grind the residual material; after about one minute, you can turn off the host and analyzer motor, stop grinding work, and stop the fan motor.
