Definition Comminution is a generic term for size reduction. Crushers and grinders are types of comminuting equipment. (1) have a large capacity, (2) require a small power input per unit of product, (3) yield a product of the single size or the size distribution desired. An ideal crusher or grinder
The RETSCH Mixer Mills are used for size reduction and pulverization of small volumes of hard, medium-hard and brittle samples as well as for soft, elastic or fibrous ones. Thanks to the high energy input, grinding times are usually very short. The CryoMill is ideal for grinding temperature-sensitive materials and samples with volatile components.
The mill uses grinding tools that can be interchanged to handle a range of soft to medium-hard materials, providing the advantages of customized grinding in one housing. After outlining the universal mill's components, operation, and maintenance, this article gives information on grinding tools, special applications, and mill selection.
Size Reduction. Size reduction is a process of reducing large solid unit masses into small unit masses, coarse particle or fine particles. Size reduction process is also referred to as commination and grinding. When the particle size of solid reduced by mechanical means it is known as milling. Size reduction operation divided into two category –.
