Open circuit grinding consists of one or grinding mills, either parallel or in series that discharges a final ground product without classification equipment and no return of coarse discharge back to the mill. We are prepared to support remotely via phone, Skype, TeamViewer and VPN.Jul 31, 2014 There are efficiency factors for dry grinding, open circuit ball milling, mill diameter, oversize feed, grinding finer than 75 microns and too large or too small reduction ratios. For cement application, the dry grinding (EF1), mill diameter (EF3), oversize feed (EF4) and fine product (EF5) factors are relevant.
This study was conducted in Mouteh grinding circuit. Mouteh gold processing plant is located in Esfahan province,center of Iran, close to Mouteh open pit mine. One of the main problems in this circuit is low efficiency grinding operation. In this study, first grinding circuit and its performance parameters are evaluated. Laboratory.Filtration. Grinding is carried out in a fully autogenous (AG) mill. The mill operates in closed circuit with a pebble crusher. Throughput is approximately 380 tph. Cyclone overflow from the grinding circuit is fed into a flotation circuit for the recovery of lead, zinc and silver. Two concentrates are produced (lead and.
Keywords Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.The main parameter influencing particle size from the circuit is ore feed rate. Although other factors like water addition, grinding media loading, etc. play a minor role, it was assumed that these in circuit parameters remain constant for purposes of the control strategy. Water addition at Cyclone 1 is used to control particle size.
