Processing Plant & Equipment — Wet-Process Production Line

Our processing plant houses a complete wet-process production line — from primary crushing through wet grinding, multi-stage magnetic separation, classification, dewatering, and drying. Over 40 million CNY has been invested in this equipment specifically because wet processing achieves iron content (Fe2O3) levels 2-5 times lower than dry processing from the same ore. This investment is the foundation of our quality advantage.

Crushing Station

Raw ore from the quarry first passes through our two-stage crushing circuit. The primary jaw crusher handles large boulders (up to 800mm), reducing them to approximately 150mm. The secondary cone crusher further reduces the material to 10-20mm — the optimal feed size for wet ball milling.

Vibrating screen — classifying crushed material by size

Conveyor belt system — transporting crushed ore between stages

Wet Ball Milling

Crushed ore is mixed with water and fed into large ball mills where grinding media reduce the particle size to 100 mesh (K100 grade) or 200 mesh (K200 grade). The wet grinding process is critical: water slurry liberates individual mineral particles — including tiny iron-bearing inclusions trapped inside larger grains — making them available for magnetic capture in the next stage. This liberation step is impossible in dry grinding, which is why wet-processed products achieve dramatically lower iron content.

Slurry pump station — moving ground material between stages

Magnetic Separation

This is where our quality advantage is created. The ground slurry passes through multiple stages of high-intensity wet magnetic separators (HIWMS). Each stage progressively removes finer and more weakly magnetic iron-bearing particles — from strongly magnetic magnetite in stage 1, to moderately magnetic biotite in stage 2, to weakly magnetic hornblende and ilmenite in stage 3. This progressive multi-stage approach is why our K200 achieves Fe2O3 of just 0.08%.

Classification, Dewatering & Drying

After magnetic purification, the clean slurry passes through hydrocyclone classifiers for precise particle size control, concentrator tanks for water recovery, and filter presses for dewatering. The filter cake enters rotary dryers where hot air reduces moisture to below 1.0%. Recovered water is recycled in a closed-loop system.

Packaging & Support Equipment

Dried nepheline powder is packaged using automated filling equipment into either 1,200kg FIBC jumbo bags or 50kg PP woven bags. Our plant includes overhead cranes for bag handling, a packaging machine for accurate weight filling, and a control room for monitoring the entire production line.
