F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.

Fig. 6 shows one set of results, where the circuit capacities are shown in three-ball-size ternary diagrams for various feed sizes with a circulation ratio of 2.5 at a size reduction ratio of 45:1 using a 1 m diameter ball mill. It can be seen that maximum contour lines stay in the bottom of …
If rods are used instead of steel balls, the mill is referred to as a 'rod mill'. Closed-Circuit or Open-Circuit. Ball mills may operate in a closed-circuit, or open-circuit. Closed circuits return a certain amount of the ball mill's output back to the ball mill for further size reduction.
Crusher Reduction Ratio I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.
End Peripheral discharge and center peripheral discharge rod mills are described in detail on pages 28 and 29. Feed and discharge heads of Rod Mills are conical in shape providing important advantages over a mill with straight heads. 1. They provide the essential feed pocket and also a space for the pulp to squeeze from the rod mass.
Calculation of reduction ratio in crushing [image: (135-5-3)] Crushing Equipment The selection of the right crushing equipment is influenced by many factors some of which are upstream of the crushing plant (e.g. blasting pattern and mining method) and others which are downstream of the crushing plant (e.g. mill and grinding circuit selection).
Jun 12, 2015· Impact crushing, particularly the kind that uses the most suitable cage mill available, has a number of advantages over compression crushing. Cage mills produce a more cubical product of consistent high quality, and they are capable of a very high ratio reduction.
The reduction ratio R in rod mills varies from 2 and 20 depending on the characteristics of the ore The usual reduction ratio is about 8 According to Bond 4 the reduction ratio is a function of length and diameter of the mill The optimum reduction ratio R RO can be written as.

Reduction ratios of 15:1 used to be the norm for quality applications (e.g. engineering steels) some 10-20 years ago, but even this expectation has fallen with the advent of modern continuous casting practices. Reduction ratios as low as 8:1 are currently acceptable for many high quality long product applications: Residuals
in a combination bar and rod mill, both the Morgan Rod Reducing/Sizing Mill and Morgan Bar Reducing/Sizing Mill are integrated to work with the same single-family pass design. High mill efficiency can be maintained without regard to order of product size. • The patented combination drive unit provides a compact footprint for tight
A: Forging reduction is generally considered to be the amount of cross-sectional reduction taking place during drawing out of a bar or billet. The original cross-section divided by the final cross-section is the forging ratio (say 3:1). There is an equivalent reduction on upsetting for forgings being upset during forging (gear blanks, for example).
EF6 – Reduction ratio (rod mill). Chat Now. Ball Mill Instruction Manual (PDF) - BICO Inc. The F.C. Bond Ball Mill is a small universal laboratory mill used in calculating the grindability of all ..... when the reduction ratio R/ = r/P is less than 8, the cal-. Chat Now.
Rod mills with high reduction ratio. Rod Mill Design Calculations 911metallurgist The mill diameter, low or high ratio of reduction, and oversize feed factors also must be applied to the calculated grinding power When calculating rod mill power for a rod millball mill circuit, do not allow for improvement in the ball mill performance due to receiving rod mill feedget price
Dependent upon the Material and the Process! I seen feed as large as 100mm on soft material. There are specialty rod mills where you target a low ratio of reduction such as end and center peripheral discharge than feed need to be targeted to product size required based upon the calculate reduction ratio in the rod mill.
The reduction ratio r in rod mills varies from 2 and 20 depending on the characteristics of the ore the usual reduction ratio is about 8 according to bond 4 the reduction ratio is a function of length and diameter of the mill the optimum reduction ratio r ro can be written as.
crushers and cone crushers whereas rod m ills and ball mills, ... All crushers have a limited reduction ratio m eaning that size reduction will take place in stages.
The reduction ratio, R, in rod mills varies from 2 and 20 depending on the characteristics of the ore.The usual reduction ratio is about 8. According to Bond [4], the reduction ratio is a function of length and diameter of the mill. The optimum reduction ratio, R RO, can be written as
Reduction Ratio; Under given load and particle size requirement, capacity is a function of mill length and diameter: Q = kLD 2+N. N is related to mill diameter which decreases with larger diameters k a constant equal to π /4. A chart showing rod mill capacity vs. mill diameter [image: (135-8-5)] A chart showing rod mill capacity vs. mill length
Nov 27, 2015· Good figures for rod and bar mills are 90 % to 93 %, for structural mills, the good mill utilization figures are 75 % to 78 %. If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs …
Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.
The mill diameter, low or high ratio of reduction, and oversize feed factors also must be applied to the calculated grinding power. When calculating rod mill power for a rod mill-ball mill circuit, do not allow for improvement in the ball mill performance due to receiving rod mill feed.
