Abstract. It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.

Power input to the shaft = Power input to the crusher / Transmission efficiency = 731.7 / 0.9 = 813 kW Answer Calculate the efficiency of the crusher. Efficiency of the crusher = Power input to the crusher / Power input to the shaft = 731.7 / 813 = 0.90 or 90% (rounded to two decimal places) Therefore, the efficiency of the crusher is 90%.

The power of the electric motor is determined taking into account the power expended to overcome all resistance forces during the operation of the crusher: NDR = N. 1 + N 2, (1) . where N1 – the power required for crushing the material; N2 – power expended on friction in the bearings; η – transmission efficiency.
The actual capacity may vary depending on the specific design and operating conditions of the impact crusher. Power Calculation: The power consumption of an impact crusher is influenced by various factors such as the size and hardness of the feed material, the feed rate, the efficiency of the crusher, and the properties of the …
The results clear that increasing the crusher's rotational speed decreased the crusher's efficiency at any sieve diameter. Fig. 6 reveals that increasing the crusher's rotational speed from 1200 to 1800 rpm decreased the crusher's efficiency from 61.13 to 48.62, 75.18 to 52.93, and 92.85 to 67.63% at 6, 8, and 10 mm sieve hole diameters ...
Currently, the dimensions of the largest Blake-type jaw crusher in use are 1600 mm × 2514 mm with motor ratings of 250–300 kW. Crushers of this size are manufactured by Locomo, () and others. The crusher is the C 200 series having dimensions 1600 mm × 2000 mm driven by 400 kW motors. Table 4.1.

Crusher Efficiency Calculations. Sep 15, 2014 It must be at least 36 in wide for an 18 x 36 jaw crusher So a 4ft by 8ft screen would be acceptable The 1in screen is a second deck for the 38 tph from the jaw crusher, so the deck correction factor is 090 and that screen capacity is 21 x 09 = 189 tph/sq ft The screen area needed under the jaw ...
(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.
A Crusher Production Management System (CPMS) is specialized software meticulously crafted to optimize and streamline production processes within crusher and mining operations. It offers a suite of tools and features aimed at enhancing efficiency, safety, and profitability. Developed after extensive research, including direct visits to various ...
Educational Resources. Efficiency can be defined by the ratio of the work done by a machine to the energy supplied to it. To apply what this means to your crusher, in your reduction process you are producing exactly the …
It is seen that for a reduction ratio of 1.32, the relative efficiency of crushing a multi-layer of particles is 72%. Note that crushing ratios in a ball mill are not well defined, but are believed to range up to 1.5 or even 2.0. In a second series of measurements, the particle size was not uniform—a distribution of particle sizes ...

At 2220 rpm the relationship was. kW = 21.8 + 1.55 (tonnes/hr) It can be seen that in terms of the conventional Bond calculation, the crusher appears very inefficient; typically less than 10%. In terms of the modified calculation, however, it can be quite efficient. In reality, the true efficiency will not be quite as high as this modified ...
The capture of a crushed piece occurs due to the stop located on the roll (see Fig. 1 ); in this case, the condition for formation of a complex stress state in the crushed piece is observed, and the energy consumption is reduced by 39–40% [ 9 ]. Fig. 1. Schematics of the crusher with stops on a roll. Full size image.
Let's assume the density of the specific crusher run is 2500 lbs/yd³. Using the formula provided, we can calculate the amount of crusher run needed: CR = (50 x 10 x 0.5) x 1.25 / (2500 / 2000) ≈ (250) x 1.25 / 1.25 = 250 tons. So, for this particular area, approximately 250 tons of crusher run gravel would be require.
