Business Solution Overview
Lower Energy Consumption: The mill is described as saving 20% to 30% power consumption compared with a ball mill. For powder producers, this can improve operating efficiency and reduce energy cost over continuous production cycles.
Integrated Processing Functions: By combining crushing, drying, grinding, separating and conveying in one machine, the system can simplify plant layout and reduce the need for multiple standalone process units.
Supports Moisture Handling: The machine offers strong drying capacity and can dry and grind raw materials with moisture content as much as 15%. This helps processors handle a wider range of feed conditions within one grinding solution.
Cleaner, Quieter Operation: The vertical grinding mill uses totally closed negative-pressure operation to reduce dust during operation. Noise is also stated to be 20 to 25 decibels lower due to no direct contact between grinding rollers and grinding disc.
Reduced Wear and Contamination: The stated metal wear rate of only 5 to 10 g/t supports lower wear-related maintenance and helps limit metallic pollution in processed powder.

Why Choose CLUM Ultrafine Vertical Powder Grinding?
High Grinding Efficiency
The mill is stated to save 20% to 30% power consumption compared with a ball mill. Energy savings can increase further as moisture content rises.
Strong Drying Capacity
It can dry and grind raw materials with moisture content as much as 15%. This supports more flexible feed handling in mineral powder production.
Multiple Functions in One System
The machine integrates crushing, drying, grinding, separating and conveying. This makes it suitable for streamlined powder processing lines.
Low Noise Design
Because there is no direct contact between the grinding rollers and grinding disc, metallic impact is avoided. Noise is stated to be 20 to 25 decibels lower.
Closed Dust-Controlled Operation
Totally closed negative-pressure operation is employed by the mill. This helps prevent dust during operation.
Low Wear and Reduced Metallic Pollution
Metal wear is stated at only 5 to 10 g/t. This supports lower wear rates while helping reduce metallic contamination in the finished powder.
