The main purpose of the crushing and grinding operation is not to reduce the ore particle size, but to dissociate the useful minerals from the gangue minerals. Therefore, the ultimate development goal of the grinding operation is to obtain the highest mineral liberation degree with the minimum energy input.
Selective grinding refers to a kind of grinding phenomenon in which the ore fragmentation degrees is different in the grinding process due to the difference in hardness between minerals. The main purpose of the crushing and grinding operation is not to reduce the ore particle size, but to dissociate the useful minerals from the gangue minerals.

In cylindrical grinding operation, the work is mounted between two centres and is rotated. A grinding wheel is mounted on a spindle and revolves at much higher r.p.m. than the work. The work centres are mounted on a table which can traverse at various feeds so that the entire length of the work passes to and fro in front of the wheel. The depth ...
Inside diameter grinding, also called as internal grinding, is used for grinding the inner diameter of tubular object. Workpiece or object will have already drilled hole and internal grinding process will be performed to finish the inner surface of workpiece with the help of small grinding wheel rotating at higher revolution per minute.
The main kinds of cylindrical grinders are standard, universal, automated, and limited-features. Grinders may also be classified by their method of work holding and method of control, manual or automated. Grinding wheels, maintenance, coolant, and grinding variables vary based on the operation and type of machine. Cylindrical grinding is a ...
What is the purpose of the grinder The most important purpose of the grinder is to keep the working tool in proper conditions and reduce costs of the purchase of a new tool. The working tool is in fact any cutting tools including knives, scissors, joiner´s and other tools having similar properties and functions.
Keep in mind that a grinding wheel is a form of cutting tool, and except in the case of wheel for general purpose grinding, the abrasive, grit size, grade and structure, bond type should be selected to fit the particular job on which the wheel is to be used, just as a cutter, drill or tap is selected for its specific job.
