How was a 120,000-ton-per-year grinding mill production line built in Qinghai?

A 120,000-ton-per-year ore grinding production line has been built in Qinghai Province. Many difficulties were encountered during construction, but all were overcome. The following is an introduction to this grinding production line:

Ore Grinding Production Line Construction Plan Consulting

Project Overview:

Raw Material: Light-burned magnesia

Capacity: 120,000 tons/year

Output Fineness: D90 < 12μm; D50 < 5μm

Finished Product and Uses: High-density, high-purity magnesia (for refractory materials)

Equipment Configuration: 8 SCM micro-powder grinding mills

Project Challenges

1. Special Material Characteristics

Magnesium oxide is chemically unstable and easily absorbs moisture from the air during grinding, causing blockages, reduced production, and other problems. This makes it more difficult to process than other materials.

2. Environmental Challenges

The project is located in Qinghai Province, at an altitude of 1800-2000 meters. Unlike plains areas, thin air is a natural phenomenon at higher altitudes, requiring extremely high-performance fans to ensure stable operation.

3. Limited Space

This project involves layout design within an existing factory building, requiring consideration of both production line flow design and end-product manufacturing processes. Compared to previous open designs, the site constraints are greater, increasing the design complexity.

4. Reduced Costs and Increased Production

The client is highly focused on operating costs and return on investment, demanding that production efficiency be improved while minimizing operating costs.
