The Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a pre-defined media and ore charge. The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits. The test requires a minimum of 10kg of sample that has been stage-crushed to passing size of <3.35 mm.

Score: 0 Accepted Answers: 5.26 kW For Q.No. 3 the actual power consumption, when efficiency of the grinder is 15%, is 35.1 kW 49.6 kW 78.9 kW None of the above No, the answer is ...

work constituents to understand the process flow of base mix preparation, and identify the areas for improvement and make modification to achieve higher production. This project is all about Hammer mill failure during flux crushing. The Hammer Mill consists of roller; hammer beams and hammers type of configuration.

I cannot substantiate my information but I think they were to run around 1100 RPM at the cylinder in the mill. Watch the rate you feed the mill and it should work at the 1100 rpm speed. There is a determination method for establishing the feet per minute of the hammers that is used to establish the RPM.

Hammer mills - The hammer mills grind by means of a high-speed rotating steel "hammer" and has a sieve in the periphery through which the sample leaves the grinding chamber. By selecting different sieves, the particle size distribution in the sample can be varied. The hammer mill is typically used to produce a fine and homogeneous sample.

This is because work index frequently changes as a function of the product size in comminution. If target grind size during a project is changed, or if the test is run at the wrong product size, then it is necessarily to provide a correction. The goal of this work is to create an equation to adjust a Bond ball mill work index from one P 80 basis

Chronologically, the hammer mills have emerged after the (high speed) motorized wheel mills. The rotation speed ranges indeed differ significantly between the two different types of mills, from 200-1200 rpm for wheel mills and 2500-6000 rpm for hammer mills, this speed does not allow a manual, nor animal-driven drivetrain.

WORK INDEX •Work Index, Wi, is the gross energy requirement in kilowatt hour per ton of feed (kWh/ton of feed) to reduce a very large particle to such a size that 80% of the product will pass through a 10micrometer, or 0.1 mm screen. •If Dp is in mm, 𝑊𝑖=𝐾 1 𝐷𝑝𝑝 𝐾 = 0.1𝑊𝑖=0.3162𝑊𝑖 I =0.3162𝑊𝑖 1

Grinders like hammer mills, rolling-compression mills, tumbling mills, etc. Grinders are . n = 3/2, Bond's Law: 4. . Bonds law is often written in terms of the work index (Wi) as, Where the work index is defined as the energy required per unit mass in kWh/ton to reduce

Swing hammer type fibrizer is used in preparation & excellent in operation for in sugar industry. Preparation index is depended on power, grid plates, front wall etc. This is helpful with modification in so that preparation index is increased also it is easy in working, less maintenance, less power consumption & cost reduction machine.

The rod mill work index laboratory test is conducted by grinding an ore sample prepared to 80% passing 12.7 mm (½ inch, the original test being developed in imperial units) to a product size of approximately 1 mm (in the original and still the standard, 14 mesh; see Chapter 4 for definition of mesh), thus determining the rod mill work index (Wi R or RWi).
