Reasons And Solutions For The Stones Thrown At The Discharge Port Of The Ball Mill. When the feeding amount exceeds a certain limit value, the ball mill will throw out unground broken stones from the outlet, and the amount of stones thrown out is still large, which not only increases the power consumption of the ball mill, but also increases the labor of the personnel. strength

Oct 19, 2016 In such cases as those, a light weight sheet steel discharge housing is supplied by the user to accommodate the local plant layout in conjunction with the discharge launder. Ball Mill Lubrication Procedure. TRUNNION BEARING LUBRICATION. For the larger mills with trunnion bearings provided with oil seals, we recommend flood oil lubrication

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e

Discharge of pebbles, finer rock, ball scats and slurry from mills and its flow through trommels, and into other processing operations has strong impacts on overflow ball mill performance

Trommels remain widely and often work with the screening of mill discharge streams. Tumbling mill (AG, SAG, rod, and ball mills) discharge streams usually pass through a trommel screen attached to the mill outlet to prevent grinding media scats from reaching subsequent processing equipment, and the case of AG/SAG mills, to extract pebbles to

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight

The milling circuit then involves two rod mills, followed by spiral classifiers and then two ball mills to ensure material is the appropriate size for liberation by flotation at approximately 74 microns. ... The circuit feed is sampled on each of the rod mill discharge launder by automatic samplers

A guide to maximising ball mill circuit classification . 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

If a ball mill uses little or no water during grinding, it is a ‘dry’ mill. If a ball mill uses water during grinding, it is a ‘wet’ mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills

Jun 24, 2015 The discharge end of the Grate Discharge Ball Mill has at least ten times the discharge opening area, through the grate slots, compared to the common trunnion overflow type mill. The discharge grates are designed to run clean and free of any blinding or choking. The pulp level in the mill may be varied by merely changing the pulp dilution

Apr 25, 2016 The two types of ball mill in general use are the grate mill and the open-end mill. Most manufacturers make both kinds; the difference between them is that the grate mill has a steel grid clear across the discharge end, but the open-end mill has only an open trunnion at the discharge end, through which pulp flows freely

Feb 02, 2016 Lime slurry and sodium cyanide solutions are also added to the ball mill feed chute at a rate of 250 litres per hour and 80 litres per hour respectively. The ball mill is an overflow type discharge mill, and is designed for a 45% ball charge. Balls should be added on a regular basis as they are consumed in the mill

Is your ball mill as grate or overflow discharge? By feed launder, you mean ball mill feed chute (as in the mill is full) OR the launder feeding the mill (as in the material full is too viscous)? What size grinding balls are you using? What P80 grind size to you want to get from the ball mill?
