Live ChatClosed circuit systems The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.

Live ChatBall mills are the classic grinding plants Around the world they are the most common installations. Ball mills convince thanks to their simple principle and low maintenance needs They are robust, durable and extremely reliable in operation. By using ball mills in closed circuit with a separator, their efficiency can be increased even further.

Live Chatto the second milling circuit that runs in closed circuit with its own cyclone (Cyclone 2). Ball mill 2 discharges to a sump where water is added before the slurry is pumped to Cyclone 2. Cyclone 2 overflow gravitates to a distributor and is combined with Cyclone 1 overflow before gravitating to the flotation circuit. Cyclone 2 underflow circulates back to Ball Mill 2. SCADA system

Live ChatABC closed circuit, Autogenous Ball Mill Crusher. Another similar technique is the ABC open circuit where the crusher product feeds the ball mill rather than the autogenous mill. Crusher product is typical feed to a ball mill using large diameter balls but not much grinding of 20 25 mm ore can be accomplished in an autogenous mill.

Live ChatThe circuit comprises a SAG mill, 12 m diameter by 6.1 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW gearless drive motor with bi directional rotational capacity.

Live ChatGenerally, the output of the closed circuit ball mill is 15% ~ 25% higher than that of the open circuit ball mill with the same size. However, the superiority of the closed circuit grinding system is closely related to the comprehensive performance of the powder concentrator, the selection of ball mills technological parameters, the arrangement method of pipeline and the level of production management.
