The crushed ore is conveyed to a traversing rock box and thence to one of two crushed ore bins adjacent to the main hoisting shaft. A loading station conveyor is interlocked with the winder to provide automatic ore hoisting.All phases of ore handling have been mechanized as completely as possible. Results to date indicate this policy has been ...

Newcrest had people watching the bins to ensure they didn't overfill – but it was an unpleasant job. Now, using Microsoft Azure, Newcrest takes data from its crushed ore bin soft sensor, then uses intelligent edge AI and data science techniques leveraging a machine learning algorithm that predicts the level of crushed ore in the bin.

collect the caved ore from drawpoints and tip the ore into run-of-mine (ROM) ore bins feeding jaw-gyratory crushers. The crushed ore is subsequently passed to surge bins that provide material onto a series of collection conveyors. The main trunk belt fed by the collection conveyors transports the ore to the surface at a conveyance rate of 4600 ...

The challenge facing Newcrest at Cadia was managing the levels in the underground crushed ore bins. If the bins overfill, they have to be manually emptied introducing lengthy and expensive production delays. Conversely, if the level drops too low it is unable to effectively feed the collection conveyor. Newcrest had spotters, physically ...

The ore is crushed underground to minus 6 in. and hoisted to 140-ton surface bins. From there it is fed to a 7-ft. cone crusher after passing over a double-deck screen that removes 1¼-in. undersize from the crusher feed. The product of this crusher plus the product of all other crushing units in the plant is then conveyed to …

Crushed ore bin conveyor and reversible conveyor; Two crushed ore bins with 2,260 t capacity each (wet basis) Two crushed ore bin belt feeders; Ball mill feed …

CALAVERAS COUNTY. 61 Reduction jjlant: The ore is hauled from mine bins in 5-ton cars by25-ton locomotive to crushing plant, where the ore is crushed by No. 3type D Gates gyratory crusher to 1J-inch size; crushed product iselevated to 18x72 trommel and screened to f-inch size, oversize fromtrommel to 24x36 ]IcFarland rolls, fines conveyed to

Ore Bin (Silo) Safety. Around these ore storage bins or areas there are three possible places of work, on top, under, and in. Each one has their own brands of danger, and methods of safety and …

The best ore contained 60-65% copper. (Left) These massive timbers supported the 400-ton crushed ore bins. Next the ore was passed through a trommel. Oversize material went to conveyors where the highest grade ore pieces were hand-picked for direct shipping to the smelter in Tacoma, Washington.

All the ore delivered to the Mill's ore bins were first crushed to a more uniform size (2 inch maximum), then transferred to elevators for additional processing in the upper levels of the Mill. Name: Preparing Argo equipment for display. Date: Circa 1980 Phase: Maxwell years

He said, during a period of six months, the mine experienced 4,780 minutes of downtime due to sensor failure in one of the crushed ore bins. The new solution can pull data from upstream sensors (tonnes tipped, apron feeder speeds, weightometers, etc), and the AI model then analyses the data to predict the level of crushed ore in the bin and ...

The secondary crusher product is screened by a vibratory screen and sent then to fine ore bins. The oversized product is transferred to tertiary cone crusher for crushing. Finely crushed ore is stored in two ore bins with 250tonne and 350tonne storage capacities. The grinding circuit consists of two ball mills and are fed independently from ...

Although every plant uses a different form of ore storage, there are 3 basic types of storage used in the oil sands: (1) stockpiles, (2) concrete silos and (3) surge bins. TYPE 1. STOCKPILE. The simplest form of ore storage comes in the form of a stockpile, a technology borrowed largely from the coal mining industry.

The sinking of No. 7 shaft, to provide for the more efficient mining of the ore developed in the southern end of the Broken Hill South Mine leases, necessitated reorganisation of the winding and coarse crushing plant at the mine. ...
