View DetailsQuartz & mineral color sorter
A mineral color sorter is not a grain sorter with a wider chute. Quartz, feldspar, calcite, baryte and fluorspar arrive as dense, angular rock with dust on the surface, so the machine has to hold every particle steady in front of the camera, see a colour difference of a few percent, and then reject it with an air pulse strong enough to move real weight. A quartz sand sorting machine that cannot do all three is just an expensive way of moving waste from one pile to another.
JIACUI builds this ore optical sorter around the belt platform instead of a gravity chute: a heavy-duty anti-wear belt, high-resolution CCD optics with optional near-infrared channels, and a positive-pressure optical enclosure that survives quarry dust and wash-line humidity. The same industrial stone color sorting equipment handles silica sand, feldspar, calcite, baryte, talc and fluorspar, and returns a predictable, repeatable cut between product and waste — whether you are chasing SiO2 purity and whiteness for glass and engineered stone, whiteness for ceramics, or consistent grade for metallurgical and filler buyers.
Applications
Colour and texture are the two signals that decide the sale price of an industrial mineral. The matrix below shows, material by material, which defects a JIACUI optical sorter rejects and what that rejection is worth at the end of the line.
| Mineral / material | Defects and waste removed | Quality and value gained |
|---|---|---|
| Quartz & silica sand | Yellow skin, iron-stained patches, black mica and foreign rock. | Raises SiO2 purity and optical whiteness for glass, slab and engineered-stone production. |
| Feldspar & calcite | Dark inclusions, iron oxide spots and discoloured stones. | Meets the high-whiteness requirements of ceramics, glaze and industrial filler grades. |
| Baryte & talc | Impurity-laden gangue, mud lumps and off-colour rock. | Stabilises specific gravity and gives a consistent chemical grade shipment after shipment. |
| Fluorspar & calcium carbonate | Low-grade waste stone, yellow-green impurities and silica contamination. | Lifts metallurgical and industrial grade, protecting the commercial value of the finished lot. |
Engineering
Four design decisions separate a machine that survives a quarry from one that survives a showroom. Each of them is visible in the numbers you get at the end of the line.
Unlike chute-type sorters, the flat belt on a belt type mineral sorter stops material from rolling and bouncing, so high-density, large-particle ore keeps a steady trajectory from 0.5 mm up to 50 mm+. That stable presentation is what makes consistent sorting of lump ore possible.
Industrial cameras resolve ultra-fine colour difference — faint yellow streaks, subtle shade drift and small dark inclusions that a human picker cannot hold a standard on. Both visible-light and near-infrared channels are available for low-contrast minerals.
An enclosed optical compartment with positive-pressure air purging and IP-rated sealing, built for quarry dust, wash-line humidity and continuous 24/7 duty rather than a clean plant room.
Ultra-hard alloy nozzles resist abrasive impact and deliver short, precise air pulses, so healthy mineral is not blown out with the reject. Nozzles are user-replaceable in minutes.
Belt vs. chute
Agricultural sorting usually runs on a gravity chute. Mineral sorting mostly should not: dense, angular rock does not slide — it tumbles. Three practical consequences follow, and each one shows up directly in your yield.
Material is carried, not dropped. Every particle reaches the camera at the same angle and speed, which is the single biggest reason belt sorters beat chutes on coarse, heavy ore.
Fine silica sand, gravel-sized aggregate and crushed rock can all run on the same belt with a feed-rate adjustment — no second machine for a different cut size.
No free-falling impact against the viewing window. Abrasion is concentrated on replaceable liners and the belt itself, which keeps maintenance cost predictable in a mining duty cycle.
FAQ
Yes. We supply water-resistant, wet-sorting belt configurations with high-efficiency water drainage and anti-fogging optical lenses, so washed quartz lines can be sorted straight after dewatering without drying the material first.
Capacity runs from about 3 tonnes per hour to over 20 tonnes per hour per machine, depending on particle size distribution, belt width and how evenly the feeder spreads the material. We confirm the exact figure on your own sample before quoting.
Key contact areas are lined with replaceable high-chrome anti-abrasion steel plate and polyurethane buffers, and the conveyor belt is reinforced. Ejector nozzles use ultra-hard alloy, so abrasive ore wears consumables instead of the frame or the optics.
Yes. Colour models are stored as recipes, so switching between white quartz and yellow quartz is a recipe recall on the touch screen, not a hardware change. The demo video on this page shows that switch being made on one machine.
Send us a sample of your raw quartz, feldspar or ore. If you are sizing a quartz color sorter or a complete mineral sorting line, our lab runs a full sorting test, measures the post-sorting purity and whiteness, and returns a tailored technical proposal with a factory-direct price — free of charge, no obligation.
