Comminution

Grinding Equipment

Grinding equipment further liberates crushed mineral particles, creating the particle size range required by downstream processes such as flotation, magnetic separation, gravity separation or leaching. The mill you select defines the capacity and energy profile of your comminution circuit.

Grinding Equipment manufactured by Xinhai — Grinding Equipment

Equipment in this category

On this page you compare mill types and work through the selection variables that testwork settles. Your decision balances capital cost, operating cost and metallurgical necessity for the specific orebody.

The catalogue range spans from primary autogenous mills to fine grinding vertical stirred mills. Energy Saving Ball Mills, Grid Type and Overflow Type Ball Mills handle wet or dry grinding across diverse tonnage. Rod Mills tend to intermediate sizes and coarser products. Raymond Roller Mills serve fine dry grinding duties.

What decides the selection

Test programmes typically settle the specific energy requirement using Bond work index or measured grinding energy. Then throughput and product particle size targets define the mill size and number of grinding stages. Closed-circuit classification arrangement and liner selection follow from the duty and wear considerations.

Parameter boundary

The catalogue states that a rolling-bearing design saves 20-30 percent energy against conventional sliding bearings. This is a manufacturer product claim. Actual savings must be verified against a defined baseline machine, the ore duty and measured power draw.

Technical parameters

189 models across 8 machine types, as published in the Xinhai equipment application manual.

Parameter boundary

These are standard-model catalogue figures. Actual capacity, power draw and wear life shift with ore properties, feed gradation and circuit conditions. Treat them as a shortlisting aid, not as a performance guarantee for your duty. Final selection rests on testwork, flowsheet calculation and a written confirmation from the manufacturer.
