Product Introduction
Grinding after crushing and before mineral separation.
A ball mill is a rotating grinding machine that uses grinding media to reduce crushed material to a finer product. It is commonly installed after crushing and before classification, flotation, magnetic separation or another downstream process.
Ball mills are discussed for gold ore, copper ore, iron ore and industrial materials when controlled grinding is required. Wet or dry operation follows the confirmed process route; see the wet vs dry ball mill guide for the main selection differences. For a typical classifier return loop, read how a ball mill and hydrocyclone closed circuit works. For a smaller gold ore project comparing a wet pan route with a ball mill circuit, see the wet pan mill vs ball mill buyer guide.
Main Features
What this machine does in practical operation.
- 01Impact and attrition
Grinding media and material move inside the rotating cylinder to reduce particle size.
- 02Wet or dry process
Feeding, discharge and auxiliaries are arranged for the confirmed process.
- 03Documented model range
Existing Zhongji technical sheets provide model, feed, product and motor references.
- 04Circuit integration
The mill can work with classification and downstream mineral-processing equipment.
- 05Replaceable liners and media
Liners and grinding media are selected and maintained for the confirmed mill and duty.

Technical Details
Grinding Principle
How a ball mill reduces crushed material.
The rotating cylinder lifts part of the grinding media and material. As they fall and move inside the cylinder, impact and attrition reduce the particles. The product then leaves through the configured discharge system.
Process stepWhat happens inside the millWhat the buyer should check
FeedingCrushed material enters the rotating cylinder through the feed end.Feed size, stability, moisture and upstream crushing condition.
GrindingGrinding media and material move together, producing impact and attrition.Material hardness, target fineness, media condition and operating load.
DischargingGround material leaves through the selected discharge arrangement.Required product size and whether closed-circuit classification is needed.

Maintenance & Installation Notes
Maintenance and Installation
Use records and inspection results to plan maintenance.
The checklist below is a planning framework. Exact intervals and procedures must follow the supplied manual, operating hours, process, material and site safety rules.
Daily / Each Shift
- Observe noise, vibration and temperature.
- Check lubrication status and visible leakage.
- Watch feed, discharge and circuit stability.
- Record abnormal operating changes.
Weekly
- Inspect accessible fasteners and guards.
- Check drive and lubrication points.
- Review product-size and output records.
- Check visible liner and discharge condition.
Monthly
- Review media and liner wear trends.
- Inspect alignment and support condition.
- Compare temperature and vibration records.
- Plan parts and media replenishment.
Annual / Major Shutdown
- Complete a qualified inspection of major components.
- Check drive, bearings, liners and supports.
- Replace confirmed worn components.
- Review spare-parts and maintenance records.
Safety: Stop, isolate and verify the power before inspection or entry. Confined-space, lifting and electrical work require qualified personnel and site procedures.
Installation preparation
Confirm foundation dimensions, anchor positions, centre-line alignment, feed and discharge connections, lubrication and maintenance clearance before delivery.
Grinding media and liners
Media grading, loading, liner profile and liner material must match the confirmed mill, material and process. Do not copy one fixed recipe to every application.
Commissioning
Check alignment, guards, lubrication and rotation direction, then complete the no-load and controlled-load checks required by the supplied instructions.
Common Operating Problems
Common Operating Problems
Check the whole grinding circuit before changing the mill.
These are general checking directions, not a substitute for the equipment manual or site safety procedure.
Observed problemPossible checking directionPractical response
Low output or coarse productFeed change, unstable feeding, media condition, classifier setting or circulating load.Check the complete circuit against the confirmed design condition.
Abnormal vibration or noiseLoose fasteners, alignment, foundation, drive parts, liner condition or unsuitable load.Stop for inspection instead of continuing under abnormal operation.
High bearing or drive temperatureLubrication, alignment, load, cooling or component condition.Stop safely and check the lubrication and drive system.
Wet-process leakageSeal, joint, liner fastening, feed or discharge connection.Locate the source after safe shutdown and repair the confirmed component.
