Crusher Power Consumption And Nip

Establishment of energy consumption model

Compared with the traditional cone crusher, under the same chamber size and particle size distribution, mass fraction of crushed products below 12 mm increased by 11.83%, total energy consumption of the same throughput reduced by 19.16%, the energy consumption ratio increased by 8.18%, throughput increased by 26.5%, which can effectively reduce the energy consumption and improve the crushing

Roll Crushers - ScienceDirect

01/01/2016· Power Consumption of Roll Crushers. Within the same reduction ratio the power consumption of roll crushers varies widely. The power required could be expressed by the general equation (6.8) P = capacity × reduction ratio × work index. In industry, the low pressure smooth surfaced rolls are designed to draw 8–50 kW of power under dry conditions. The heavy duty rolls draw

Tips to maximize crushing efficiency - Pit &

13/05/2019· The closed-side setting of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degrees. Too large of an angle causes boiling in the crushing chamber. This is where the jaw plates cannot grip onto the rock, and it keeps slipping up and down, avoiding being crushed. The nip angle gets flatter as the machine is set tighter. The settings on a jaw crusher are designed

Building a shear crushing specific energy

The energy consumption in single particle shear crushing was measured and the fractal theory was introduced to analyze the mass distribution of crushed particles. With the help of crushing specific energy consumption, a fractal prediction model of crushing energy consumption was established, and R-R model was used to correct the model.

01/01/2016· Power Consumption of Gyratory and Cone Crushers. To compute the power consumption of gyratory crushers, knowledge of the ore work index and crusher capacity is necessary. In its simplest form, the power consumption is given by (5.5) P = W i Q F 80 − P 80 F 80 100 P 80 where P = power (kW) W i = work index (kWh/t) Q = capacity (t/h)
