STEP 01 · STRUCTURE

First determine the tank structure: vertical or horizontal?

The structure of the ball mill tank must match the movement mode of the equipment. Vertical tanks emphasize sealing and high energy input, while horizontal tanks are more suitable for rollers, bottle rollers and long-term uniform grinding.

How to complete crushing and mixing in the ball mill tank?

The equipment drives the tank to rotate, swing or vibrate, and the grinding balls impact, rub and shear the material under the combined action of centrifugal force, gravity and inertia.

01Load sample and grinding ballReserve reasonable free space

02Produce impact effectCrush larger particles

03Friction and shear refinementContinuously reduce particle size

04Obtain uniform powderComplete crushing and mixing

5-STEP SELECTION

It is recommended to follow these 5 steps to complete the selection

1Matching equipmentConfirm the movement method and fixture

2Confirm the pollution limitMetal and non-metal pollution boundary

3Compare material hardnessThe tank hardness is higher than the material

4Check chemical compatibilityAcid, alkali, solvent and temperature rise

5Determine capacity and processCharging amount, ball-to-material ratio and atmosphere

STEP 02 · MATERIAL

Select materials according to "pollution, hardness, corrosion, atmosphere"

No ball mill tank is suitable for all samples. Prioritize what is allowed to be introduced into the sample, how hard the material is, whether corrosive media will be used, and whether a vacuum or inert atmosphere is required.

01 / Contamination restrictions

What samples are allowed to be brought in?

The upper limit for the introduction of metallic elements, oxides or organic matter.

02 / Material hardness

Can the tank hold up?

The hardness of the tank and grinding balls should be higher than the material to be ground.

03 / Chemical Environment

Are acids, bases and solvents compatible?

Wet grinding media may change material stability.

04 / Atmosphere requirements

Are you afraid of oxygen or water?

Use a vacuum tank or inert atmosphere for protection if necessary.

Evacuate or fill with inert gas through the valve group.

Key: valves, seals and pressure levels

Important reminder: "Low pollution" does not mean "zero pollution". Before formal selection, it is recommended to conduct real material grinding samples and perform element or component testing on the ground samples.

STEP 03 · CAPACITY & PROCESS

The larger the capacity, the better: it must match the single batch sample volume and equipment

First confirm the tank shape, single tank mass and rotational speed range allowed by the equipment, and then infer the tank capacity based on the sample volume, ball-to-material ratio and free space.

DRY / WET

Dry grinding or wet grinding?

Dry grinding facilitates powder recovery; wet grinding helps dispersion and temperature control, but solvents, seals and subsequent drying conditions must be checked.

ATMOSPHERE

Vacuum / inert atmosphere

Samples that are easily oxidized, absorb water or are active should use vacuum tanks with valves, and check the vacuuming, filling and pressure-maintaining processes.

SAFETY

Temperature rise and sealing safety

Wet grinding and long-term operation may produce temperature rise and internal pressure. A safe space must be reserved and the speed, time and pressure must be controlled.

EQUIPMENT MATCHING

Match the ball mill tank according to the equipment movement mode

Planetary ball mill

High energy input and obvious combined movement require strict matching of tank size, total mass and clamping structure.

Laboratory drum ball mill

Emphasis on smooth rolling and long-term mixing, focusing on checking the tank diameter, length, load-bearing and roller spacing.

STEP 04 · GRINDING MEDIA

The grinding ball and the tank must be considered as a complete set

The material of the grinding ball determines the source of impact energy and wear; the combination of ball diameter affects the coarse particle crushing, refinement efficiency and final particle size distribution.
