Re: Preblending (Stacking And Reclaiming) Page 1 Of 1
Preblending (stacking and reclaiming) question 1. while our plant was designed in 1998, the necessity of preblending stacker and reclaimer system was not incorporated based on the ground that run of mine limestone quality is very consistent(cao standard deviation 0.60 per cent) and silica, iron or alumina oxide are very less in the range of 0.6,0.1,and 0.3 per cent respectively.
Reclaimer reclaimer consists of a hoe or a rake which extricates crushed material in layers of small thicknesses. extricated material falls on conveyor running across the width of the pile and drops it on a belt to take it to respected feeding hoppers of grinding section. thus the hoe and conveyor also move on rails for entire length of the pile.
Reclaimers generally operate on a side stream of 1–3 of the total amine circulation rate. reclaimer sizing depends on the total inventory of the plant and the rate of degradation expected. reclaimer operation is a semicontinuous batch operation. the reclaimer is filled with hot amine solution and, if necessary, soda ash is added.
