Industrial Machinery
Ball Mill
A horizontal ball mill (1.6-210 t/h, up to 3550 kW) that grinds dry minerals into fine powder with steel or ceramic media, for mining, cement, chemicals and building materials, with continuous feed and energy-saving drive.
Shape sand, grind powder, recover metal
Beyond crushing, aggregate and mineral plants need shaping, grinding and separation. VSI sand-making machines shape crusher output into cubical manufactured sand; washers clean it. Raymond and ball mills grind minerals to fine powder, and magnetic separators and flotation recover valuable metal from ore.
These machines are engineered for continuous, high-tonnage duty with wear-resistant internals and energy-saving drives. OCALWA supplies them as single units or integrated into complete sand-making and ore-beneficiation lines, matched to your material and output, from a verified factory.

Frequently asked questions
The VSI shapes and sizes crusher output into manufactured sand, typically in the 0-5 mm range with a cubical shape and controllable fines, adjusted by rotor speed and feed mode. A washer removes excess powder.
Raymond mills suit soft-to-medium minerals (limestone, gypsum, calcite) to a fine powder with a small footprint and low cost. Ball mills handle harder ores and higher tonnage, and are used in ore grinding circuits. We match the mill to your material and fineness.
Magnetic separators recover magnetite and other magnetic minerals; flotation recovers copper, gold, lead-zinc and more. The right route (magnetic, flotation, gravity or leaching) depends on the ore, which we design as a flowsheet.
Both. Buy a single VSI, mill or separator, or a complete sand-making or ore-beneficiation line with feeder, crushers, mill, classifier, separation and dewatering, delivered turnkey. We size everything to your output.
Lead time is a few weeks to a couple of months by size, ex-works or FOB China, with a 12-month warranty on main parts and wear parts (liners, hammers, screens) as consumables. Exact terms come with each quote.
Yes. A single VSI, mill or separator can be matched to your current crushers and screens, or we design a full sand-making or beneficiation line. Send us your current setup, material and target and we specify the fit.
Yes. Beyond single machines we deliver complete crushing, sand-making and ore-beneficiation lines turnkey (EPC): layout design, manufacture, shipping, on-site installation, commissioning and operator training, from a verified factory. OCALWA has supplied a complete production line to Colombia.
