Development of a model estimating energy consumption values

Most of the costs in open pit quarry operations occur in crushing and grinding processes. Therefore, the management of crushing–grinding processes is very important. Many researchers investigated the effects of pile size distribution and specific charge values occurring as a result of blasting on crusher energy consumptions and A limestone mines are opencast type and is nearby plant area and clays mines also found nearby to save transportation cost. After drilling and blasting, the limestone is excavated from open cast mines and loaded into dumpers and transported to crusher se4ction for crushing.

Modern Technological Applications for Limestone Mining

Rippers can be used for limestone mining as limestone is a ‘rippable’ sedimentary rock (refer to Sect. 3.1.1) Using rippers in small mines or for a group consisting of more than one mine is economical and productive. Instantaneous blasting or blasting with delay detonators in mines are executed in circuits.For the sedimentary rocks (Siltstone) the specific crushing energy is approximately 1.26 kJ/kg.

Predicting the overall specific energy requirement of crushing

Observed vs predicted conventional crusher specific energy. No-load power tends to be relatively high in conventional crushers and hence net power is significantly lower than the motor input power. From examination of the 18 crusher data sets the motor input power was found to be on average 35% higher than the net power.Size reduction control of cone crushers has received fairly little attention over the past few decades. Consequently, the most common control objective is still to regulate the crusher load (crusher power or crusher main shaft piston pressure) or the closed side setting (the shortest distance between crushing liners), not the actual size Size reduction control in cone crushers ScienceDirect

Physical Bauxite Processing: Crushing and Grinding of Bauxite

3.1 Introduction to Crushing and Grinding of Bauxite. The most common initial process step to feed an alumina refinery with bauxite is the crushing or sizing of the raw bauxite material that is extracted from the mine. The feed material is crushed or sized so that it is conveyable, as well as correctly dimensioned, for the next step in the process.The specific energy value was determined from the stirred ball mill power of 178 Nm/s by filling ratio of 70% (the solid mass concentration was 20%).
