Classification Equipment

Classification equipment separates mill discharge into coarse and fine streams, returning oversize to the grinding circuit. It controls the particle size that reports to downstream recovery processes. The page covers hydrocyclones, cyclone units, spiral classifiers and high-frequency fine screens.

Classification Equipment manufactured by Xinhai — Classification Equipment

Equipment in this category

Selecting the right classifier turns on feed characteristics, target cut size and process layout. Readers typically evaluate single-stage or multistage arrangements, material wear life and integration with existing pump or gravity systems.

Hydrocyclones handle fine cuts and high throughputs in a compact footprint, often grouped as cyclone units. Spiral and submerged spiral classifiers suit coarser separations with a gentle action that preserves particle size. High-frequency fine screens deliver sharp size separation at fine cuts, while air classifiers serve dry processing where water is limited.

What decides the selection

Start with the target cut size and required throughput, then define slurry density and feed pressure. Pilot or laboratory testwork establishes achievable classification efficiency, overflow fineness and underflow density for your ore. These results, combined with wear data for lining materials, guide the selection of unit size and number of parallel lines.

Technical parameters

116 models across 9 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.
