Used Colloid Mills

Aaron Equipment Company buys and sells unused and used colloid mills. A colloid mill is a machine that is used to reduce the particle size of a solid in suspension in a liquid, or to reduce the droplet size in emulsions. The high tip speeds, combined with an extremely small shear gap, produces intense friction on the material being processed. The friction and shear that result is commonly referred to as wet milling. The rotor and stator are cone shaped, and have three stages of increasingly fine serrations, or grooves. The stator can be infinitely adjusted to obtain the desired gap setting between the rotor and stator. The grooves change directions in each stage for increased turbulence. Colloid mills are used across many manufacturing industries, especially in the pharmaceutical, food and chemical industries. It is great for making small to medium-sized batches of product, which could include anything from toothpaste to peanut butter.
