The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing mm (6 mesh) to product size in the range of 45150 µm (325100 mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work ...

Ball mills are sometimes used in singlestage grinding, receiving crusher product. The circuits of these mills are often closed with classifiers at highcirculating loads. These loads maximize throughput at a desired product size. The characteristics of ball mills are summarized in the Table, which lists typical feed and product sizes.

Working Principle Operation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the ...

B : Capacities are based on tests with grinding material of 80% and mm in pass particle size to produce products of 80% and 74mm (approximately 200 mesh). However, the raw material particle size shows new feed rate to the mill, the product particle size shows overflow rate from classifier, and the processing capacity shows new feed rate (i ...

umClosing: The closing mesh size the test was run at, also called P 100 or P 1. Convert to µm, if needed, before entering into the database. F 80: Sample feed size in µm (and usually will provide a particle size distribution) P 80: Sample finished product size in µm (and usually will provide a particle size .

The particle size distribution, the number of particles of different sizes, is responsible for important physical and chemical properties such as solubility, flowability and surface reaction. In many industries such as food, pharmaceutics and chemistry traditional sieve analysis is the standard for production and quality control of powders ...

Besides, some materials can reach 2000 ball mill is widely used in refractories, cement, new building materials, glass ceramics, silicate products, black and nonferrous metal beneficiation and other production industries. Moreover, the equipment can also be divided into drytype ball mill and wettype ball mill.

The ground product is discharged from the mill through discharge slots provided in the mill tube, through a discharge wall or through the end trunnion. The design and setting of the discharge slots or discharge wall determine the grain size distribution of the ground product.

P = The 80% passing size of the ground product in µm F = The 80% passing size of the feed in µm . The test is a closed circuit dry grindability test performed in a standard ball mill. It can be performed at mesh sizes ranging from 28 mesh to 400 mesh. The normal finishing size is 100 mesh. Feed Sample Requirements 10 kg of minus 6 mesh
