Dense medium machine processing method for palm kernel/ shell separation

Journal of Applied Sciences and Environmental Management, 2018
A machine processing method for the separation of cracked palm kernel from the shells using dense medium is presented. Cracked palm kernel is a mixture of kernels, broken shells, dusts and other impurities.

Multi step prediction of dense medium clean coal ash content based on time series alignment and TCNformer

Gong-kuang zidonghua
Due to the different positions of various sensors during the dense medium separation process, there is a time lag between the main process parameters of dense medium separation and ash content, which affects the results of clean coal ash content.

Experimental validation of a fluid dynamics based model of the UF Falcon concentrator in the ultrafine range [PDF]

, 2012
The process of separating ultrafine particles, say below 80 μm, on the basis of density is a true technical challenge. Indeed, the separation process itself becomes very much size dependent with such fine particles, so that large enough density ...
