Grinding :

Mechanical process aimed at reducing the particle size of a solid material using various mechanisms such as compression, impact, shear, etc.

Particle distribution size :

The distribution of particle sizes in a sample or material.

Micronization :

Reduction of particle size on the scale of micrometers (microns).

Hammer Mill :

Type of mill using rotating hammers to crush or pulverize materials.

Ball Mill :

Grinding device using metal balls to reduce the particle size in a rotating medium.

Roller Mill :

Mill consisting of two rotating cylinders used to crush or compress materials between them.

Impact Mill :

Mill where particles are struck by hammers or beaters to reduce them in size.

Blade Mill :

Mill where rotating blades cut or chop materials.

Disk Mill :

Mill using rotating disks to reduce materials to fine powder.

Attrition Mill :

Mill where particles collide with each other, causing wear and size reduction.

Cryogenic Mill :

Mill using cryogenic temperatures to make materials brittle and reduce them in size.

Size reduction :

Decrease in the particle size of a material.

Sieving :

Process of separating particles of different sizes through a sieve.

Aggregat :

Solid particle aggregate used in construction, typically derived from the grinding of rocks or similar materials.

Air-Jet Mill :

Mill using an air jet to produce fine particles.

Reduction Ratio :

The reduction ratio measures the size reduction of a material after grinding compared to its initial size. It is usually expressed as a percentage and reflects the efficiency of the grinding process.

Hardness :

The hardness of a material in the context of grinding refers to its resistance to being reduced in size. Harder materials often require more powerful grinding methods.

Friability :

Friability assesses how easily a material can fragment or break. In grinding, friable materials are more easily reduced to smaller particles.

Moisture content :

Moisture content measures the amount of water present in the material. In grinding, high moisture content can influence the viscosity of the material and its behavior during the grinding process.

Dry process :

Dry grinding is done without the addition of water. It is often used for dry materials or when moisture can be avoided for performance or specific finished product reasons.

Energy consumption :

Energy consumption in the context of grinding measures the amount of energy needed to reduce the particle size. It depends on the type of mill, material properties, and the process used (dry or wet). Lower energy consumption is generally desirable for economic and environmental reasons.
