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.

Key words: power draw, cement, dry grinding, ball mill ... right mill for the specified duty is the most critical for circuit design, since it has the ... Bond method has been used for ball mill selection in both mineral and cement.

Dec 30, 2012 · Posted December 29, 2012. I would suggest that you build a rod mill if you want to get the material down to a fine power, a ball mill usually is used to make bigger item smaller, big rocks down to little rocks, and then the material goes into a rod mills to take it down to a powder.

Abstract: One of the methods for the design of a ball mill is Bond method. In this type of machine operating conditions are critical and any change affects your design. In this paper a numerical program (BMCrush) was developed with the purpose of providing a tool for the design of a ball mill using the following methodology: (1) the sizing of ...

Typically R = 8. Rod Mill Charge: Typically 45% of internal volume; 35% – 65% range. Bed porosity typically 40%. Height of bed measured in the same way as ball mills. Bulk density of rods = tons/m3. In wet grinding, the solids concentration 1s typically 60% – 75% by mass. A rod in situ and a cutaway of a rod mill .

Jan 03, 2020 · Grinding Studies. Two kinds of mills, BBM and LBM, were used to achieve the desired P 80 passing percentage of 150 μm with an acceptable range of hematite liberation (> 75%) at optimum grinding time. The BBM is a standard ball mill having a length and diameter of 300 mm × 300 mm with smooth liner as shown in Fig. rotating drum is attached to a gearbox and has adjustable speed knob.

Simulations indied that the target would be achieved at a 15% ball charge level using the Bond equilibrium ball size distribution. Validation. A new laboratory test was conducted with torque mill considering a 15% ball charge level that was determined by simulation.

Sepor's batch ball and rod mills are designed to give size reduction of laboratory quantities of minerals and ores. Feed size should generally be 1/8″, for ball mill and 1/2″ for rod mill. They are of a sturdy, rugged design to handle frequent use with hard materials. The batch ball and rod mills require a drive roll to rotate the mill ...

Due to the limitations of the Bond method for designing industrial grinding circuits, simulation using phenomenological mathematical models has been increasingly used for projects destined to design and to improve the ball mill performance. The simulation method also allows assessing the integrated performance of comminution circuits.

Yes, we can assist with optimisation. To achieve this at both the design and operating stages, we will require some representative sample for specific comminution test work. The test work will entail industry standard tests such as the Bond Rod Mill Work Index, Bond Ball Mill Work Index, JK/DWi tests and then some specific batch mill tests.

Nov 16, 2015 · The VRM for cement grinding offers a significant advantage in power savings. Typically, the VRM uses 50% less power than a ball mill when grinding the same clinker to 3900 Blaine. VRMs are also much more adept at handling hot feed compared to ball simple and compact vertical mill layout is cost competitive to build and offers many options for layout, even in existing plants.
