Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
SIZE REDUCTION Impact and attrition:(Fluid energy mill) Principle and operation: 1.Size reduction occurs due inter-particular attrition and impact on turbulent particles. 2.Made up of loop of pipe internal diameter 2 to 20 cm and height 1-2 m. 3. Pipe allows free movement of .
Let's take a look at the specific types of particle size reduction, so you can get a clear idea of what size they actually are. Crushing. Crushing is generally considered to reduce particles, like large rocks, to gravel-sized material. This translates to roughly 0 to 5 mesh. Grinding. Grinding is generally considered reduction to table salt ...
The result size of crushing down to 50 mm, while grinding size range from hundreds to tens microns or < 10 microns. Reduction ratio. Crushing is performed in several stages, reduction ratios are ranging from three to six in each stage. The reduction ratio in grinding can up to 100, therefore it consumes a considerable amount of energy.

Industrial Pulverizing Equipment Your Solution to Size Reduction. Request A QuoteSince 1834 Stedman Machine Company has been a consistent leader in size reduction technology and industrial rock crushing equipment manufacturing.Our size-reduction equipment is designed to increase profits by maximizing the production of marketable product and reduce equipment down time.
An initial size reduction from material several centimetres in diameter down to one centimetre, or so, is often termed primary crushing. This may be followed by further size reduction, secondary crushing, and then pulverising, or fine grinding. The term micronising has become popular for the reduction of particle size to this dimension.
Rittinger's Law — The energy required for reduction in particle size of a solid is directly proportional to the increase in surface area. E = K R f c (1/L 2 – 1/L 1) Kick's Law — The amount of energy required to crush a given quantity of material to a specified fraction of its original size is the same, regardless of the original size.

The beater plates (2) support the hammers (3), and distribute the particles around the periphery of the grinding chamber. The hammers grind the solid against the liner (4) of the grinding chamber. The beater plates rotate between 1600 and 7000 rpm (revolutions per minute) to reduce the size of the incoming particles.
