Experimental study on a sludge mixing and crushing machine used in aerobic composting
|
Abstract:
A sludge mixing and crushing machine was developed to match the requirements of particle size and moisture in aerobic composting of municipal sewage sludge.Machetes of spiral layout were used to mix,crush and transport sludge and amendments(including mushroom residues and sludge compost) successively.Experimental data showed that mixture with right particle size(less than 20 mm) and moisture(about 60%) could be got by changing the mix ratio of sludge and amendments.The volumetric mix ratio(R) of sludge and ...
