The wet milling machine benefits make them attractive investments. IKA wet milling machines are based on the rotorstator principle. Exhibiting a high level of shearing energy input, milling machines can achieve particle sizes of 10 µm and below. IKA wet mill machines are capable of processing products with a broad spectrum of viscosity.

The water can wash away the fine particles in time to avoid overgrinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.

It is very noisy machine. 3. Ball mill is a slow process. 4. Soft and sticky material cannot be milled by ball mill 5. At low speed, the balls will slide or roll over each other and only negligible amount of size reduction will occur. 6. At high speed the balls will be thrown out to the wall by centrifugal force and no grinding will occur.

Now that we have a basic understanding of the industrial milling process, let's examine the difference between wet milling and dry milling. Dry milling typically uses particleonparticle contact to reduce materials' size, while wet milling involves dispersing the material in a liquid and using solid, grinding elements to reduce size.

Ball mill diameter, media size and mill revolutions per minute (rpm) control the process of powder mixing and particle size reduction (Upadhyaya, 1998). For given mill size and media, too low an rpm extends the process time, whereas too high an rpm leads to poor cascading of media, leading to inefficient particle size reduction. Other ...
