5 FAQs of Manufacture ball mill for gold mining 900×3000 ball mill grinding machine

What are the key technical specifications of the 900×3000 ball mill for gold mining? The 900×3000 ball mill has a drum diameter of 900 mm and length of 3000 mm, powered by a 55–75 kW motor. It operates at a rotation speed of 36–38 RPM and holds a maximum grinding media load of 3.5 tons. Designed for wet or dry grinding, it efficiently processes gold ore into fine particles, with a discharge size adjustable between 0.074–0.4 mm. Its robust construction includes high-quality steel plates and liners for durability.

What is the processing capacity of the 900×3000 ball mill? This ball mill processes 1.5–2.5 tons of gold ore per hour, depending on ore hardness, feed size, and desired output fineness. For softer ores, throughput may increase, while harder ores require longer grinding cycles. Optimal performance is achieved when paired with a classifier to recycle coarse material, ensuring consistent particle size and maximizing gold recovery rates.

What grinding media materials are suitable for this ball mill? Steel balls (high-carbon or alloy steel) are standard due to their density and wear resistance. For gold ores requiring minimal contamination, ceramic or rubber-lined drums with stainless steel or alumina balls are recommended. Media size (25–100 mm) should match ore characteristics—smaller balls for fine grinding, larger ones for coarse feed.

How often does the 900×3000 ball mill require maintenance? Routine checks include lubricating bearings every 8–10 hours and inspecting liners every 3–6 months. Replace worn liners or grinding media when thickness drops below 60%. Gear and motor inspections should occur every 6–12 months. Proper maintenance reduces downtime and extends the machine’s lifespan to 8–10 years under normal use.

What safety features are included? The mill includes overload protection to halt operations during voltage spikes or mechanical stress, emergency stop buttons, and safety guards covering rotating parts. Ventilation systems minimize dust exposure, and anti-vibration pads reduce noise. Operators must follow lockout/tagout procedures during maintenance. Compliance with ISO and mining safety standards ensures reliable operation in harsh environments.
