Work Index Ball Mill, alluding to the grind ability list of Metals, is utilized to demonstrate the granulating trouble of the material. It is measured by a rule that to compute the work file ball plant in light of yield of every unrest of the factory after the material is ground to an adjusted state by the predetermined plan.
has to supply this energy and it has a different (higher) work index than the crusher (ie the ball mill is less energy efficient than a crusher and has to input more energy to do the same amount of size reduction). Hence from equation 7, to crush to the ball mill circuit feed size (x. 2) in open circuit requires specific energy equivalent to:
Bond Work Index Cone Crusher. a secondary crusher is a jaw crusher, cone crusher and impact crusher. type of fine grinder is the ball mill the power predictions for ball mills typically use the following form of the bond equation fred bond ball mill power draw ...

Figure 5 displays the plot of rod mill Work Index (Wi RM) versus UCS. These
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
Crushing means different things for different operations and the production goals are not always equal. In Mineral dressing, these two approaches are adopted: 1. Crushing of rock and gravel 2. Crushing of ore and minerals. There are three stages in crushing as stage 1, 2 and 3. In each stage the reduction in size ranges as referred to as R1,R2 ...

The Bond lowenergy impact crushing work index (more informally, the Bond crushing work index) is not as common as the Bond ball mill work index, and it is a notoriously noisy test.. The test is a 'perspecimen' test where individual specimens of prepared rock are handpicked by the test operator and placed into the apparatus.
The distribution is on the basis of mass. What is work index of this sample? No, the answer is incorrect. Score: 0 Accepted Answers: 4) A material is crushed in a Blake jaw crusher such that the average size of particle is reduced from 100 mm to 20 mm with consumption of energy 10 points
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to m. Product: 300mm (for transport) to .
30/07/2020 · A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s). Sample requirements: A minimum of 8 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus mm, as required for the Bond Ball Mill Work Index test feed.
GRINDABILITY TESTS Bond Rod mill work Index • The rod mill work Index is also normally distributed with and average and median of /t • It is common to observe difference between the ball and rod mill caused by variation in ore hardness • The test has been mainly used for the design of rod mill or primary ball mills. http ...
