Essential Considerations for Limestone Powder Grinding-Raymond mill

Limestone powder is a widely used material across various industries, including construction, agriculture, and chemical production. To process limestone into powder, a grinding process is required.
Today, we will share key considerations regarding limestone powder grinding mills and limestone powder grinding plants to achieve efficient and eco-friendly production.
Applications of Limestone Powder
Fineness of Limestone Powder | Applications |
---|---|
Coarser than 200 Mesh | Lightweight bricks, soil conditioners, etc. |
200 Mesh – 325 Mesh | Desulfurization powder, cement, glass, chalk, etc. |
400 Mesh – 800 Mesh | Rubber, plastics, sealing materials, chemicals, toothpaste, etc. |
1250 Mesh – 1500 Mesh | Coatings, stationery, cables, cosmetics, pharmaceuticals, etc. |
2000 Mesh – 3000 Mesh | High-end papermaking, high-end PVC, high-end fillers, high-end silica gel, etc. |

The Raymond mill is an early and commonly used grinding machine. It can grind rocks with a Mohs hardness of no more than 9.3 and a moisture content of less than 6%.
The fineness range of the finished limestone powder is 80-325 mesh, which can meet the fineness requirements of most industries.
In addition, with the development of technology, the structure and function of Raymond mills have also been improved.

The specific improvements are as follows:
The powder separator has been changed from the drag-and-drop transmission inside the cavity to the suspended transmission outside the cavity, which has enhanced its stability and durability.
The grinding roller rotates around the central axis to maximize the grinding force.
The cylindrical structure can prevent the bellows and air ducts from being blocked.
The electrical system adopts centralized control, reducing labor costs.
Precautions for limestone grinding process

Ensuring grinding efficiency and reducing dust pollution are the two most important aspects of limestone powder grinding.
The former is the main factor for achieving the expected economic benefits. The latter is an important measure for protecting the environment and achieving sustainable development.
Ensure grinding efficiency
The production capacity of the grinding machine is a very important factor affecting profits. How to ensure the grinding efficiency of the grinding machine during the grinding process?
Control the spindle speed
When the working power is insufficient or the drive belt wears out, the spindle speed will decrease, resulting in a reduction in grinding speed. Therefore, during the powder processing, it is necessary to pay attention to whether the milling machine has sufficient operating power and replace the worn transmission belt in a timely manner.
Check the wearing parts
The wear of vulnerable parts such as grinding machine blades, grinding rollers and grinding rings will also reduce the powder output rate. Therefore, inspecting and replacing vulnerable parts is also an important component of ensuring grinding efficiency.
Inspect the pipeline
Poor sealing can clog the air duct, leading to an increase in dust. Therefore, the seals of the grinding machine need to be carefully inspected before operation. Once the air duct is blocked, stop the operation and clear the pipeline in time.
