What is the difference between the sand mill and the ball mill?

The sand mill and the ball mill are two commonly used grinding equipment, and they have some significant differences in design, working principle and application:

How it works:

Sanding machine: The use of high-speed rotating grinding medium (such as sand) in the liquid medium for fine grinding of materials. It mainly relies on the collision and friction between the grinding medium to achieve the refinement of the material.

Ball mill: The use of a group of metal balls or ceramic balls (grinding medium) in the cylinder body tumbling and impact, crushing and grinding of the material, suitable for dry grinding or wet grinding.

Grinding medium type:

Sand mill: Usually use a small particle grinding medium, the diameter is generally between 0.1 and 3 mm, suitable for high fineness requirements of the material.

Ball mill: The use of large grinding medium, the diameter can range from a few millimeters to tens of centimeters, suitable for the grinding of large granular materials.

Applicable material status:

Sand mill: mainly used to deal with liquid state materials, usually used for suspension or slurry materials, suitable for high viscosity materials.

Ball mill: can handle dry powder or wet pulp, a wider range of application.

Granularity control:

Sanding machine: Fineness can be controlled more precisely by adjusting the type, size and flow rate of the grinding medium.

Ball mill: fineness control is relatively not flexible, usually more dependent on the running time of the mill and the type of grinding medium.

Application field:

Sand mill: widely used in coating, ink, medicine, cosmetics and other products requiring high fineness.

Ball mill: used in mining, metallurgy, building materials, chemical and other industries, suitable for coarse crushing, fine grinding and mixing in the process.

Construction and cost:

Sand mill: The general structure is more complex, and the manufacturing cost may be relatively high.

Ball mill: simple structure, relatively low manufacturing cost.

In general, both have advantages and disadvantages, and the choice of equipment depends on the specific application needs, material properties and production process requirements.
