The FC Bond Work Index Test Ball Mill was designed by F C Bond for use in determining the Bond Index a measure of grindability and power required for grinding appliions The FC Bond Mills are used in laboratories throughout the world A copy of Fred C Bond's Method of Crushing and Grinding for determination of the Bond Index is .

· Equations for power draft, capacity and work input for predicting the performance of industrial grinding mills are derived based on torque measurements using a laboratory instrumented mill. These derivations are based on mechanical principles and on the firstorder kinetics of the grinding process. Rittinger's, Kick's and Bond's laws express work input as work index (Wi) times a particle ...

Bond's Law (1952) The work required to form particles of size Dp p from a very large particle size is proportional to the square root of the surface to volume ratio ( O𝑝 R𝑝) of the product. 𝜑𝑠= 6 O𝑝𝜑 𝑝, 𝑅 O𝑝 R𝑝 = 6 𝜑 𝑝 𝑊 = I ∝ O𝑝 R𝑝 𝑝 𝑊 = I =𝐾 6 𝜑 𝑝𝑝 =𝐾 1 𝑝𝑝 •Where, 𝐾 = Bonds constant Energy required to reduce ...

The Bond Index conforming rod charge consists of: 6 rods of " diameter and 21" length. 2 rods of " diameter and 21" length. The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a waveshaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.

Steel Ball Mills Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls .

Milling Equipment bonds work index ball mill manufactuering design and bonds A class of machinery and equipment that can be used to meet the production requirements of coarse grinding, fine grinding and super fine grinding in the field of industrial finished product can be controlled freely from 0 to 3000 mesh.

laboratory ball mill. if the mill diameter is greater than The cylindrical . Feed Characteristics . The laboratory ball mill was designed for grinding limestone, meaning that the work index required for the specific power calculation was assumed to be the work index of limestone, which is KWh/t, with a specific gravity of g/cm. 3

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones. The ...

· The Bond Ball Mill Work Index can be used in the design calculations and simulations using JKSimMet of a new grinding circuit. 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 .
