processing principle of comminution
Comminution - Wikipedia
Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with many types of mill. In dentistry, it is the result of mastication of food. In general medicine, it is one of the most traumatic forms of bone fracture.

Comminution - Mineral Processing Metallurgy
Thus the process of deducing energy relationships is largely empirical and related to particular conditions and types of reduction machinery. The present position regarding the investigation of the laws of comminution can probably be fairly summed up as follows. The problem involves extreme difficulty in the fundamental measurements.

Comminution Testing Equipment in Mineral Processing
The First Principle of Comminution It sometimes happens that the obvious is long disregarded, and this applies to the first principle of comminution. Over the years many careful laboratory investigations of comminution phenomena have been made and published. These included accurate measurements of energy input and product size particle distributions, but the results differed among themselves ...

Mineral processing - Wikipedia
Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle
MoreWhat are the Four Types of Mineral Processing?
Anything that takes large particles and makes them into small particles falls under the umbrella of comminution – this aligns with the first principle of mineral processing by creating heterogeneity. Sizing; In conjunction with comminution, there is usually some type of screening or size separation device used along with comminution equipment.

Froth flotation - Wikipedia
Principle of operation. Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution) so that the various minerals exist as physically separate grains.This process is known as liberation.The particle sizes are typically less than 0.1 mm (100 µm), but sometimes sizes smaller than 7–10 µm are required.
