What is a good grinding machine for 800 mesh lime powder?

A good grinding machine for achieving 800 mesh (or 20 micron) lime powder is a ball mill or a vertical roller mill. Both types of mills are commonly used for grinding lime powder and other materials in the mining, chemical, and construction industries.

1. Ball mill: A ball mill is a type of grinder used to pulverize materials into fine powders. It works by rotating a drum filled with grinding media (steel or ceramic balls) around a horizontal axis. The rotation creates a centrifugal force that causes the balls to impact and grind the material in the drum. Ball mills are available in various sizes and can process capacities up to 1000 metric tons per hour.

2. Vertical roller mill: A vertical roller mill is another type of grinder used for producing fine powders. It consists of a roller, which is rotated at a high speed to grind the material, and a separator that collects the fine powder. Vertical roller mills are typically used for high-capacity applications and can achieve particle sizes down to 20 micron (800 mesh).

When selecting a grinding machine, consider the following factors:

* Production capacity: Ensure the machine can handle your desired production rate.

* Final particle size: Choose a machine that can achieve the desired particle size (20 micron or 800 mesh).

* Energy efficiency: Consider the energy consumption and operating costs of the machine.

* Maintenance and safety: Choose a machine with a good maintenance record and safety features.

It is essential to consult with an experienced supplier or manufacturer to determine the best grinding machine for your specific application and requirements.
