2016-1-1 For autogenous mills, like the dry Aerofall mills, MacPherson and Turner established that the power consumption was a function of mill diameter and length. For dry commercial AG mills they derived the power as (9.8) P M = 0.992 L D 2.8 ρ c where ρ c = bulk density of the mill charge (rock plus balls and water) (t/m 3 )get price
摘要. Semi-autogenous grinding pebbles were used as a grinding medium and compared to steel balls in terms of their effect the flotation behavior of the products and their industrial application. The pebbles increased the rate of copper recovery from the concentrated products by 3.30% to 86.89%. Industrial application showed that usingget price
2018-2-20 Autogenous mill, pebbles, ore sorting INTRODUCTION A well known natural phenomenon in autogenous (AG) mills is the build-up of pebbles.

The pebbles generated are formed primarily of dolerite,get price
2019-7-4 For autogenous mills C is usually in the range 0,6¬0,9 (60 90%). and the contact forces will mainly depend upon the average pebble size in the area. In autogenous mills the coarse pebbles normally segregates radially towards the periphery leaving an excess of fine pebbles in the upper central part of the charge. The forces andget price
2015-8-6 In autogenous mills the diameter is greater than the length. They can be as much as 40+ feet in diameter. Patented in 1959, AG Mills are not so popular any more. The 5-½’ diameter mill had both pebble ports and ½” wide slotted grates. The plus ½” mill product was crushed in a cone crusher and returned to the mill feed along withget price

The SAG Mill. SAG (semi-autogenous grinding) mills have the working duty of being a primary or first stage grinder. SAG Mills function similarly to the other mills, utilizing grinding balls, but the main difference is found in its semi-autogenous functionality.

Hardinge, inventor of the conical mill and a later inventor and manufacturer of wet and dry autogenous mills, described a pebble mill at an AIME meeting: (The feed) was 1 inch and finer. The mill contained 2000 pounds of 2 and 3 inch pebbles. The ore was crushed to 80 mesh size at the rate of 4 tons per hour at an expenditure of 17 hp.get price

2009-1-1 Nowadays most semi-autogenous mills incorporate a sensor that measures the overall noise level generated by the mill in motion. In some industrial plants, this signal is used as control variable to limit the mill operating speed and/or the feed flow rate. To verify this hypothesis, a dynamic model of a SAG mill-pebble crusher circuit wasget price

"IntroductionIn autogenous mills, grinding of the ore feed is accomplished by the direct action of the variously sized rocks making up the feed on each other and the mill interior. Size reduction is achieved without the addition of grinding media foreign to the mill feed, differing in this respect from rod, ball, and pebble milling.get price
