DESCRIPTION: A flowsheet of Coarse gravity concentration followed by flotation circuit. ORE TREATED: On ores wherein base metals or gold bearing pyrite free at a coarse size. ADVANTAGES: This flowsheet illustrates the application of a concentrating table in the ball mill classifier circuit, followed by flotation of the classifier overflow at a finer mesh.
Ball grinding mill is Formed a closed system with air classifier.Coarse material will be back to ball mill to grind again, and qualified material will go to be packed by worker or packing machine. Advantage (1) It equiped with ceramic liners and grinding media is ceramic balls to keep free of iron impurity.

(The crushing plant runs 11 h per day, the mill 24 h/d.) The mill power (and media consumption) is higher and the mill grinding length is a bit longer in the open case. Is there any other side-effects associated with feeding a ball mill with 16 kW-h/tonne feed which is coarser (closed P80 of 13.4 mm vs. open P80 of 15.4 mm i.e.2 mm coarser)?
b) Feed Preparation – With more widespread use of coarse ball milling it is increasingly important to present a suitable feed material top-size to the ball mill. Significant inefficiencies are introduced as a result of the need for larger (and, as a result, fewer) grinding balls. Furthermore, as mill performance is related to the complete size distribution of the feed material, all ...
The calculated.ball mill power consumption is 13.8 Kwhr/Ton of crude. The cyclone overflow is deslimed, and upgraded in finisher magnetic separators. Diameter to Length Ratio in Mills Rod mill L/D ratio is about 1.4:1. Pilot scale tests suggest that this should be revised to about 2:1 in the case of primary ball mills.
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as …

Ball mills can be used for coarse grinding as described for the rod mill. They will, however, in that application produce more fines and tramp oversize and will in any case necessitate installation of effective classification.
Functional performance analysis of ball milling has been described previously by Mclvor. "Coarse" versus "fine" or product particle cut-off size is first selected, usually equal to some benchmark passing size of the circuit product (e.g., 80%). The function of the grinding circuit is to generate new product size material (or "fines") from "coarse" particles in the circuit feed ...

Hello Dear Experts, I bought a new ball mill which's 900x3000 size. I am planning to grind river sand that has %60 silica in it's chemical proportion. But for me it's unnecessary to grind very fine like 600 micron or near, I just want to receive 0-3 mm final product. My feed size is : 3 mm . to 25
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
