Grinding circuit. In general lines, the grinding circuit gets composed from a powdering or pulverizing process and a classification process. In most sites a ball mill gets used for grinding, to produce fine particles, and a (hydro) cyclone gets used for classification, to separate the fine particles from larger particles. The main objectives ...
Hello everyone, 1. a 40 000 tpd plant with a 15 MW primary SAG mill and 2 pcs 10 MW secondary ball mill. If you try to change the H/C feed pump without stopping or just during a short shut down of the grinding line, you may not get a single drop of slurry into the stand by pump because the feed sump is half full of ball scrap and coarse rock, blocking the pump inlet pipe of the standby pump.
Feed to the grinding circuit has the following screen analysis, which assays: The grinding mill is a 5′ x 5′ lefthand Type "B" steelhead Ball Mill with a righthand "V" to flat drive on the feed end of the mill. The ball mill is powered with a 50Hp.,, 440 volt Westinghouse Synchronous Motor.
When the cyclone returns ore to the ball mill, both the total volume of ore and the slurry density increase in the grinding circuit. This recycled ore is referred to as the circulating load. If the grinding process becomes less efficient, the circulating load will continue to rise until it exceeds the circuit's handling capacity.
There are 4 pumps (2 operational and 2 in standby) that transfers the material to a cyclones battery and then to two ball mills. When the material is fed into the SAG box, its distribution is irregular making that the pumps suck different particle sizes resulting in an irregular feed to both of the cyclones and to the ball mills.
In those days, 3 stages of crushing, and rod and ball mill grinding, were common in comminution flowsheets. Bond's Rod Mill Work Index (RM Wi) and Ball Mill Work Index (BM Wi) tests provided good designs for grinding mills. If the design was 1200 t/d, each stage had to be able to produce 1200 t/d or (54 t/h at % availability).
Grinder Pumps utilise a grinding device at the inlet with a hardened stainless steel cutting blade rotating inside a cutting ring with a number of teeth. This powerful mechanism reduces all solids down to fine particles, much smaller than a cutter pump, and allows small diameter pipes to be used. Behind the shredding mechanism is a highhead ...
Grinding Mill Control in Closed Circuit. The principle objective for controlling grinding mill operation is to produce a product having an acceptable and constant size distribution at optimum cost. To achieve this objective an attempt is made to stabilize the operation by principally controlling the process variables.
The processing plant operates with a standard SABC comminution circuit, and was the first to use the largest domestic Φ × m SAG mill ('diameter' represents nominal diameter, and 'length' of the mill represents the effective grinding length inside the end liners and discharge grates), Φ × m overflow ball mill and ...

Grinding circuit PID especially considering that minimum capital expenditure would be involved since most of the required instrumenta tion, control and communication equipment, software and servers are often already in place. ... The MPC system thus allows weighting the water split between the ball mill and pump box to reach the lowest ...
In this flow sheet there is a Rod mill, Pump, Classifier, and Ball mill. The ore travels through the Rod mill and is pumped to the classifier. This is the heart of the grinding circuit. The entire milling process is controlled "by using this piece of equipment's product as a guide. There are three different types of Classifiers, SPIRAL ...
Simple 1 "Closed Circuit" Ball Mill with Cyclone Grinding Circuit/Flowsheet. This is the path that the ore takes in this circuit. The ore comes from the fine ore storage area to be added to the mill. Again it is ground but this time the ground material is pumped to a classifier to be classified by size. The material that has not been ground ...

Similarly, Steyn and Sandrock (2013) aimed to optimize grind for an industrial singlestage closed autogenous grinding (AG) mill circuit. Grind curves were developed in terms of mill filling and mill inlet water and indicated an approximate region where optimal grind occurs. A supervisory model predictive controller was used to maintain the ...
