crushed ore is fed into a SAG/Ball mill circuit with a median size of approximately 12,000 microns. Most SAG Mills are operated in closed circuit with a screen. The screen fi lters undersized ore, normally minus inch, to a ball mill discharge sump. The combined mill discharg-es are pumped to undergo classifi cation, normally via hydrocyclones

The new Metso MD series of mill discharge slurry pumps encompass all of this experience coupled with an understanding of today’s market needs and demands for
The auxiliary grinding bodies are transported into the agitator ball mill and out of the latter via a closed circuit by means of a hydraulic conveying medium. US9216418B2 - Hydraulic milling ball feed and discharge for stirred ball mills - Google Patents
Apr 01, 2013 How a Grate Discharge Ball Mill Works | Mining & Metallurgy. … with the ball mill discharge in a common sump and is pumped to 840mm … mill discharge chute design – Crusher South Africa The mill discharge flows into the sump through a movable chute fixed below the discharge launder
(24.8 lb) of ball mill feed sample from plant survey. Sample is reconstituted with water to be the same percent solids as the plant ball mill discharge. Mill speed: 35.2 rpm (65 percent of critical speed) Length of time of test: 363 seconds Average torque reading: 1,056 in-lbs Mill HP = (1,056 in-lbs / 12 in./ft) x (35.2 rpm
2. From the ball mill discharge size distribution calculate the %+75 μ as: 100 – 26.5% = 73.5% +75 μ. 3. Calculate the CSE as the average: (80.7 + 73.5) 2 = 77.1% + 75 μ. In this example the ball mill circuit classification system efficiency is 77.1 per cent at 75 μs. This means that
One of our Ball Mills keeps losing pressure on the high pressure pump. It will run fine when starting the Mill and suddenly after a while sometimes 1hrs the pumps will loose pressure. We have just grinded the journal and installed new white metal bearings. After startup this afternoon after about 1hrs the pumps low and high just lost pressure
Mar 21, 2007 The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal
Metso Outotec mill discharge pumps have been designed for mill circuit applications, such as SAG/ball mill discharge pumps and hydrocyclone feed. Special emphasis has been placed on components that have to withstand exceptional wear from coarse heavy solids and flow turbulence, the company says
The right pump for the job improves results. This is something that the Bucim copper mine witnessed when they replaced their existing pump with Metso’s MDM300 mill discharge pump. Challenge In 2014, the mine experienced serious control issues with its hydrocyclone pump, resulting in dry running, inconsistent feed and low throughput
Pump Model: 450MSR. MSR pumps belong to SME MS series pumps which are specially designed for severe duty applications such as ball mill cyclone feed in minerals processing plants.. MS pumps are available in MSR and MSU two types of different constructions: MSR – 1. Split Outter Casing — Ductile Iron 2
