Energy efficiency in the zeolite impact crushing plant of San Andrés (Holguín, Cuba)

Abstract

The present work deals with the impact crusher energy efficiency at San Andres Zeolitic Plant. Varying the operational parameters levels (rotor velocity, hammer row number and crusher capacity) were carried up two experimental series: First series was aimed to obtain the influence of the operational parameters on the power consumed by the crusher motor; the second series evaluated the crusher specific energy consumption behavior. First series empirical model obtained describes the influence of operational parameters on power consumption. Also the relationship among specific energy consumption and crusher speed and capacity were obtained. The most efficient operational regimen corresponded to 1100 rpm of the rotor velocity, 2 hammer row numbers and 15 t/h of crusher capacity.
