The area influenced by any given hole is found as follows: (1) Divide angle at hole by 180°. (2) Multiply total area of entire prism by above result. (3) Multiply area found by (2) by the average thickness (found by solution of the formula) of ore in the hole, which thus transforms this smaller prism into volume.

Crusher Efficiency Calculations 911 Metallurgist. 19 · Sep 15, 2014 · The screen area needed under the jaw crusher is 38/189 = 201 sq ft For the 1in screen below the roll crusher the capacity has no correction factor and the area needed is 32/21 = 152 sq ft To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in wide

The gyratory crusher is the main coarse crushing equipment for iron ore [2,3], its performance directly affects the quality and cost of subsequent iron purification. During the operation of the gyratory crusher, the crushing chamber is a component that directly interacts with the ore, the performance of the gyratory crusher is mainly determined ...

It mainly includes crushing process control, crushing appliance fault diagnosis, and automatic distributing control. Crushing Process Control. To ensure the continuous, stable, and safe operation of the ore crushing production process, it is necessary to monitor the running state and parameters of key equipment (such as crusher and belt conveyor) …

The distance between rolls is calculated to be 3m. Next, determine the specific gravity of the ore. This is 2.75 tons per cubic meter. Finally, calculate the roll crusher capacity using the formula above: C = V*L*D*S*60. C = 50*2*3*2.75*60. C = 49,500 tons per hour. Enter the linear speed of material, width of the rolls, distance …

the crusher and scalp out fi nes. Primary gyratory crushers – ideally suited to all high-capacity primary hard rock crushing applications. Jaw crushers – we have more installed jaw crushers than anyone in the world. The lead-ing choice due to their high reduction ratio and heavy duty design. Cone crushers – capacities available to suit all

1. Introduction. Due to the decreasing reserves of high-grade iron ore and secondary resources used for steelmaking, it has become an important research and development area to improve the grade of iron ore through crushing (Gul et al., 2014).The quality of iron ore crushing directly affects the performance of pellets and sinter, so as to …

The ore is to be broken down in a jaw crusher to pass through a 11.5 cm screen. The undersize is scalped before feeding to the jaw crusher. Assuming the maximum feed rate is maintained at 30 t/h and the shapes of feed and product are the same and the crusher set is 10 cm, estimate the size of jaw crusher required and the production rate ...

This mod adds the following recipes to the crusher: Ore - 10 stone, 10 work amount. Coal - 10 stone, 20 work amount. Sulfur - 20 stone, 20 work amount. Quartz - 40 stone, 30 work amount. Pal Fluids - 3 Paldium for 2 fluids. There are 2 variations of this mod. You only need 1! Base.

2.2. Samples analysis after comminution2.2.1. Particle size distribution. The gold ore sample of 200 kg was first fed to the primary crusher (PEX-150 × 250 mm) and secondary crusher (XPC-60 × 100 mm) to ensure all the sample could pass through a sieve of 20 mm.The comminuted ore was then thoroughly mixed and divided, fed to the single …

Also t10 is related to reduction ratio for the same ore Fig 6.6. All good. I'm trying simulating a two stage iron ore crushing circuit to produce a maximum of lump and all I know is that the top size of the shot rock is 600 mm and the Crushing Work Index is 8-9 kW-h/tonne. Let's say a very similar ore is giving a lump to fines split of 40:60.

Crushing in Mineral Processing. In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock ( geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them ...

(pinion) power, whereas the measurement of motor power is usually based on motor input power. I have attached a calculation of operating work index that includes the motor efficiency correction, and the result is WiO=22.4 (compared to your 21.5). This correction is minor and can probably be ignored.
