Ball Mill We bring forth a highly advanced Ball Mill specifically engineered for both wet as well as dry cement grinding applications Classified depending on the circuit design bearing grinding type and drive the selection is made on the basis of the product fineness quality and nature of raw material site conditions and specific requirements
The feed of the ball mill contains grinding balls In order to effectively reduce the direct impact of materials on the ball mill feed bushing and improve the service life of the ball mill feed bushing the feeding point of the groove in the feeding part of the ball mill must be as close to the side of the mill barrel as possible
Jul 18 2016018332Operation and Elements of a Closed Circuit Ball Mill System Cement ball mills typically have two grinding chambers The first chamber is filled with larger diameter grinding media and lined with lifting liners The first chamber coarsegrinds the feed material and prepares it for the second chamber The second chamber is the fine grinding chamber
Keywords Ball mills grinding circuit process control I Introduction Grinding in ball mills is an important technological process applied to reduce the
Ball mills are the most common grinding machine employed in the mining industry Grinding occurs in a single stage or multiple stages Multiple stages may include a rod mill followed by a ball mill two stage circuit or a semiautogenous grinding SAG mill followed by a ball mill two stage circuit
grinding circuit so that the energy required to process a given ton of ore is optimal Furthermore overgrinding an ore and the subsequent production of fines can reduce the efficiency of later stages in the circuit such as flotation in conventional ball and rod mill grinding 5 to 250 mm
There are two basic types of ball grinding systems open circuit and closed circuit In the open circuit system the mill product has the fineness required for the next stage of the process In the closedcircuit system the mill product is classified in a separator in a fine fraction that is then taken to the next stage and a thick fraction

Outotec174 MH Series Grinding Mills offer a costeffective and easy to operate and maintain grinding solution across the mill lifecycle The MH Series includes a range of SAG ball and rod mills in standardized sizes with a capacity of up to 31 MW installed power and is based on over 100 years of experience with grinding technologies
Ball Mill Grinding Circuit The ball mill is in closed circuit with a sump and three cyclone classifiers The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added The slurry from the ball mill is pumped out of a sump into two cyclone separators The underflow from the
milling circuit consists of a rod mill followed by a ball mill in series Crusher product 9 mm is fed to the rod mill and the water is fed in ratio to the ore feed mass The rod mill discharge is pumped without any further water addition to the first ball mill The ball mill discharges to a sump where water is
The circuit comprises a SAG mill 12 m diameter by 61 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 bidirectional rotational capacity
Converting grinding circuits to singlestage operation AG mill operating only ball mill switched off requires some modifications to the piping layout and circuit operating philosophy Operating in singlestage requires the hydrocyclone underflow stream from the ball mill circuit to be redirected to the AG mill
Fragments of grinding media eventually accumulate in the ore being processed and can cause serious damage to other equipment in the grinding circuit such as pumps and hydrocyclones The foremost reason to use a trunnion magnet system in a ball mill is to replace the deadweight of ball
In a ball mill circuit the quotoutputquot can be defined as the production rate of fines of the circuit As for any output ball mill circuit output is a function of both its inputs and efficiencies There are two quotinputsquot to a ball mill circuit the ore fed to the circuit and the power delivered by the grinding mill
