Wet Ball Mill Procedures

May 7, 2023 nflg 0 Comments

mining companies or raw materials manufacturers use ball mills in the process of grinding ore, minerals or other materials. The wet ball mall is the key piece of equipment for grinding the ore after the crushing process completes.

Wet ball mill Viscosity

To use a wet ball mill appropriately, it is important to match the viscosity of the batch to the material being ground. Low-viscosity batches excessively wear the wet ball mill, while high viscosity batches prevent the material from being ground correctly.

Batch Size

Batch size determines the time needed to complete the batch. As wet ball mill grinding is a tedious, often long process, a larger batch may exceed an eight-hour working shift. Adjust batch size to ensure sufficient material fills all voids and slightly covers the grinding media, keeping in mind the space needed for the ball charges.

Determining Ball Charge Size

Calculate ball charges and viscosities by using smaller-sized balls for the lower viscosities and the larger-sized balls for higher viscosities. For lower viscosities, use small flint pebbles as an example, 1-1 1/2 inch or use 1-1 1/2-inch porcelain balls, 75 to 90 Kreb units (a measurement of viscosity as defined by the American Society for Testing and Materials, ASTM) and 600-1,100 centipoise, a dynamic measurement of viscosity.

Wetting Agents

Correct wetting agents or surfactants increase batch size and decrease grinding time because the agents help break down the aggregated particles’ surface tension, allowing for a greater stability of the finished product.
