Semiautogenous mills or SAG mills as they are often called can accomplish the same size reduction work as two or three stages of crushing and screening Often used in grinding at modern mineral processing plants SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stagesView Details
b Semi autogenous grinding in which the pebble fraction of mill discharge ½ in is taken out through pebble ports for separate crushing and ball milling The minus ½ in fraction of mill discharge is recycled to the SAG mill through a classifier The circuit isView Details
With over 90 years of experience we have established a profound expertise and a broad customer base in almost every application in the wet grinding and dispersing industry From fullvolume up to highenergy bead mills we set the technology standards for efficient sustainable wet grinding processesView Details
The gratedischarge type of Ball Mill has a grate at the outlet of the shell and causes less excessive grinding compared to the overflow type Therefore generally it is best suited to grind materials up to the particle sizes ranging from 60 to 100 meshView Details
These enhancing technologies accompany our grinding mills and make the grinding process more efficient which adds significant value to the whole concentration process These technologies include online particle size analyzers for the feed and discharge Outotec RockSense and Outotec PSI particle size analyzers mill charge measurementView Details
When fully in the trunion this device is able to keep enough pulp inside the grinding chamber to change the mill discharge to an overflow one with an 8 to 10 power drawn reduction When fully out it has no effect at all The mill is back to its original grate discharge conditionsView Details
specified as 2 and Cyclone 2 particle size is 30 300 µm the control loop will attempt to add water to Cyclone 1 sump to achieve a particle size of 15 300 µm If the hardness of the ore increases the particle size in the mill discharge from ball mill 1 will increase With the same water addition to sump 1 the particle size of Cyclone 1View Details
The mill grinding rate through the size of interest 150 µm the circuit target P80 calculated from the plant survey data using the functional performance equation was 00568 t kWh The ‘energy specific cumulative grinding rates’ for the survey calculated from ball mill feed and discharge sizeView Details
