Whether you're setting up a pilot plant, expanding a small factory, or processing high-value specialty minerals, these compact ball mills deliver industrial-grade grinding performance with flexible dry or wet operation, ceramic or steel lining options, and precise batch control. A proven choice for small-scale feldspar, quartz, glaze, frit, chemical, and metal powder production worldwide.
Our small ball mills (Φ600×1200 / Φ900×1200 / Φ900×1800) are batch-type horizontal grinding systems built for real production output in compact spaces.
Materials & Process Flexibility
Core Applications & Materials:
· Ceramics: Feldspar, quartz, kaolin, ball clay, glazes, frits — for tableware, tiles, sanitaryware
· Industrial Minerals: Calcium carbonate, barite, bentonite, talc, silica sand — for fillers and specialty powders
· Glass: Glass batch, cullet, silica, dolomite — for small glass factories
· Chemicals & Pigments: Titanium dioxide, iron oxide, dyes, catalysts — for batch chemical processing
· Metallurgy: Metal powders, ores, ferroalloys — for pilot testing and small-scale production
· Refractories: Alumina, magnesia, zircon sand — for refractory brick and castable production
Process Options:
| Feature | Specification |
|---|---|
| Grinding mode | Wet batch (slip/slurry) or dry batch (powder) |
| Lining options | High-alumina ceramic (92-99% Al₂O₃), rubber, or manganese steel |
| Media options | Alumina balls, flint pebbles, or forged steel balls |
| Batch capacity | 60-400 kg per batch (depending on model and material density) |
| Typical cycle time | 4-12 hours per batch (depending on target fineness) |
| Discharge | Manual port (wet slip) or tilted/vacuum discharge (dry powder) |
Load Materials — Raw materials, water (if wet grinding), and grinding media are loaded through the charging port. Media-to-material ratio is typically 1.5:1 to 2.5:1 by weight.
Seal & Set — The charging cover is bolted tight. The digital timer is set (typically 4-12 hours), and the mill starts rotating.
Grind — As the cylinder rotates, the balls cascade and grind the material by impact and attrition. The fixed recipe ensures consistent results batch after batch.
Sample Check — Periodically, the mill is stopped and a small sample is taken to check fineness on a standard sieve (45µm or 63µm).
Discharge — Once target fineness is reached, the slurry or powder is discharged. Wet slip flows into an agitator tank; dry powder is removed through the discharge port.
Clean & Reload — A quick water wash prepares the mill for the next batch — same material, or a completely different recipe.
| Model | Cylinder Size (mm) | Effective Volume (m³) | Batch Capacity (kg/batch) | Motor Power (kW) | Speed (r/min) | Liner Options |
|---|---|---|---|---|---|---|
| 600×1200 | Φ600×1200 | 0.15 | 60–100 | 1.5 | 38 | Alumina / Rubber / Steel |
| 900×1200 | Φ900×1200 | 0.35 | 150–250 | 3.0 | 35 | Alumina / Rubber / Steel |
| 900×1800 | Φ900×1800 | 0.55 | 250–400 | 5.5 | 35 | Alumina / Rubber / Steel |
| 1200×1800 | Φ1200×1800 | 1.0 | 500–800 | 7.5 | 28 | Alumina / Rubber / Steel |
| 1200×2400 | Φ1200×2400 | 1.35 | 700–1100 | 11 | 28 | Alumina / Rubber / Steel |
Case 1: Tableware Factory, Southeast Asia
· Model: 2 × 900×1800 ceramic-lined small ball mills (wet batch)
· Material: Feldspar, quartz, kaolin, ball clay for porcelain tableware
· Product: Casting slip, density 1.68 g/cm³, 45µm residue <0.5%
· Result: 300 kg slip per batch, 3 batches per day per mill = 1,800 kg/day total. Alumina-lined mills maintained body whiteness with zero iron specks. Replaced old pebble mills, output up 40%.
Case 2: Glaze Production Workshop, South Asia
· Model: 600×1200 alumina-lined small ball mill (wet batch)
· Material: Frit granules, color stains, kaolin for wall tile glazes
· Product: Glaze slurry, 325 mesh >98% passing
· Result: 80 kg per batch, 4 batches per day. Small batch size allowed 15+ different glaze colors per week. Ceramic lining prevented cross-color iron contamination.
Case 3: Calcium Carbonate Pilot Plant, Middle East
· Model: 900×1200 steel-lined small ball mill (dry batch)
· Material: Limestone chips (-20mm) for GCC filler testing
· Product: Dry powder, D97=15µm
· Result: Pilot data from the small mill was used to design a 100,000 TPY continuous ball mill plant. Scale-up prediction was within 5% accuracy.
Production-Grade Construction: Our small ball mills use the same thick steel shells, industrial bearings, and gear drives as our full-size mills — not light-duty lab equipment.
· Certified Ceramic Components: High-alumina bricks and balls are certified for Al₂O₃ content (92%/95%/99%), density, and water absorption. Mill certificates provided with each delivery.
· Pre-Delivery Assembly & Testing: Each mill is test-assembled and run without load before shipping. Ceramic brick lining is inspected for joint tightness and surface quality.
· Iron-Free Guarantee (Ceramic-Lined): We contractually guarantee iron contamination <20 ppm for ceramic-lined small ball mills. If your white product is discolored due to our mill, we provide replacement liners and media.
