Aside from the marked increase in safety the difference in mill availability that comes from using a professional reline crew and a lesser alternative can translate to 1 3 in mill availability When ore prices are low and economically times are tough there are a number of plants where that percentage of mill availability increase makes the.
SAG mill availability was expected to be 94 giving an annual processing rate of 17Mtpa of monzonite ore As the deposit contains around 9 percent of a harder.
The conditions of the liners grinding ball percentage and overall charge level inside the SAG mill without the need to pull the feed chute presents a huge opportunity for improving mill availability comminution optimization and associated cost reductions liner life prediction and reline planning and comparisons of.
Complete two other equipment checks in order to get a more complete picture of machine utilization Confirm performance that is listed on the nameplate of the machine by its makers.
Observe and measure the machines performance for a performance cycle to see if the nameplate promise is met by the machine Keep in mind that the nameplate figure is akin to your cars speedometer in that it is an estimation of the machines performance and not an exact measure Trust your own numbers if they are different from what the maker claims is the machines capability.
Include also in your evaluation of machinery the measurement of its quality Count the number of correct quality pieces the machine produces within any given cycle Next count the number of faulty or flawed pieces produced within the same cycle Deduct the number of bad pieces from the number of good pieces For instance if the total of produced pieces is 100 and 15 of the total is no good your machine quality is rated at 85 percent.
Safe and speedy replacement Thinner mill liners result in a larger volume inside the mill This means you can have a higher charge level Using composite liners also cuts the weight of the liners to about 50 percent of standard steel cast liners making it possible to work with a higher ball charge level without increasing the total weight of the mill.
Downtime and faulty products can dramatically impact productivity.
Costs energy and wear The high availability of the equipment is also essential to maximize production and profit To reach this key objective continuous and reliable information about the mill operation is vital An innovative tool which can deliver information about in mill.

Apr 01 2017nbsp018332The mill was attached to a drive shaft supported on bearings and driven by a freely suspended gearbox and motor The torque on the drive assembly was measured on line and the average value was used to calculate power The surging of the mill load caused the torque to oscillate Mill charge fillings of 30 and 40 were tested.
The grinding circuit for the Copper Mountain project consists of one FLSmidth SAG mill and two FLSmidth ball mills Figure 1 Overview grinding circuit The Copper Mountain SAG mill is 10363 mm 34 feet in diameter and 6096 mm 20 feet long It is a grate discharge mill with an inside diameter of 10363 mm 34 feet and a grinding length of 5334.
SAG mill is an investment that can produce handsome returns if extra production is needed or simply to give the mine the option to mill the hardest ores at design throughput rates Typical tests required to define a hardness variability function are given below in Figure 1.

If stored uncovered use bales harvested early in the season first and try to sell or feed all bales before the following spring.
If stored outside place bales on a well drained surface such as gravel old tires or pallets rather than directly on the ground.
The way you store hay after baling can have a big effect on hay quantity and quality losses so its worth investing additional resources money labor and equipment in hay storage.
