Size Reduction and Energy Requirement ScienceDirect For size reduction of ore in a closed circuit reduction process, Bond derived the specific energy for grinding as (33) E G = 10 W i 1 P − 1 F kWh / t Equation is the result of fundamental work by Bond It has now been accepted universally

More2016-1-1 In closed circuit, the product from the stage of size reduction is separated into relatively fine and coarse fractions. The coarser fraction is then collected and re-crushed in the same unit as seen in Figure 3.2.In doing so, the load on the equipment for size reduction is increased and a circulating load is established, but the total number of units required for obtaining the same degree of ...

MoreParticle size reduction is a critical unit process in many industries including mineral processing, cement, food processing, pigments and industrial minerals and pharmaceuticals The aim is to take large feed material and as efficiently as possible reduce the size of the particles to a target size range.

MoreThe Size Reduction Process Minerals being crystals have a tendency to break into endless numbers of sizes and shapes every time they are introduced to energy. The difficulty in size reduc-tion lays in the art of limiting the number of over and under sizes produced during the reduction.If this is not controlled, the mineral will follow its ...
