Non-metallic Mineral Processing & Purification Line Design from China

Kaolin & feldspar processing and purification lines

We design complete non-metallic mineral processing and purification lines from China — our main direction is wet processing and iron-removal purification of kaolin and potassium/sodium feldspar (feldspar in wet and dry-powder routes), with silica sand and quartz sand lines alongside. A process package, not a spare-parts catalogue.

K-Na feldspar ball-mill whole line — 3D animation 2:18 — Walk-through of a complete potassium/sodium feldspar line: loader and hopper feeding, jaw crusher, ball mill in closed circuit, wet drum magnetic separators and a slurry electromagnetic separator, thickener, dewatering, and loading of the finished product.
Kaolin water-washing whole line — 3D animation 2:22 — Walk-through of a complete kaolin wet-processing line: feeding and dispersion, spiral classification and desanding, slurry pools and pumps, water-cooled electromagnetic iron removal, filter press dewatering and product loading. Floating blue labels are in Chinese.

Main lines

Both lines come with process outline (feldspar has two routes: a wet ball-mill line and a dry powder line from our 2017 India project), a headline overview, and the free sample test for registered members; the full equipment lists, layout drawings and test reports are available to registered members. Register to get the free sample test (5–10 kg, report within 5 days).

Raymond-mill line animation, lab sample test, dry powder iron-removal test and more.

K-Na feldspar Raymond-mill (dry grinding) line — 3D animation 2:19 — Second feldspar flowsheet variant: crushing and screening, dry grinding with Raymond-type mill and collection silos, followed by magnetic iron removal stages, thickener, filter press and product loading.
Dry powder iron-removal test on a magnetic separator 0:34 — Short factory clip of a dry powder test: an operator pours dry powder into the feed of a magnetic separator, and the treated powder is collected in a container below. This is a dry process — no slurry is used.
Lab sample test — from powder to slurry to iron removal 4:00 — Behind the scenes of our sample test (first 4 minutes): white powder is made into slurry, density is checked, the slurry is run through a laboratory wet magnetic separator with a matrix of steel-wool/mesh discs, and the iron-removed slurry is collected. Send us 5–10 kg and we report within 5 days.

Full equipment lists, layout drawings and test reports remain for registered members — Register or log in.
