Jigs & Coal Preparation
Traditionally in coal processing jigs have been used to clean the coarse coal fraction, the +3/8″ or +¼" material. Today with the advent of modern fine coal jigs in the United States, its place was moved from the coarse to the intermediate coal circuit, the 3/8″ x 100 mesh. Recent theoretical performance and economic evaluations indicate ...
Size by Size Separation Characteristics of a Coal …
The present communication examines size by size separation characteristics of a Batac jig cleaning metallurgical coal. The characteristics have been measured by Probable Error in Separation, Imperfection and Organic Efficiency. Effect of NGM on the separation characteristics, if any, has also been investigated. 1 Introduction.
Mathematical modeling of mineral jigs
Batac jig shows an improved performance over that of the side pulsated Baum jig in terms of the spread of the pulse wave more uniformly over the entire deck area, even when the jig sizes are increased. The efficiency improvement is well recognized adjacent to the sidewalls of the jig, where the Baum jigs show poor performance. ...

Air Pulsated Jigs
An air-pulsated jig has teen widely adopted as a main coal washer. It may be mainly because of its many technical and economic features such as large capacity, low running cost, long life, etc. However, the recent increasing demand of fuel coal requires a higher productivity and efficiency of the air-pulsated jig. To fill this requirement ...
Cleaning of coarse and small coal (250 mm×0.5 mm)
The BATAC jig, shown in Fig. 12.4, used a different configuration than the classic Baum jig in that the air chambers providing the pulsations were mounted directly under the bedplate. The use of more sophisticated fast acting valves allowed much better control and optimization of the pulsation cycle. By eliminating the U-Tube configuration ...

Gravity Concentration By Jigs Engineering Essay
CC = 1.5 – 1.25 ( 6mm ) Jigging is a kind of gravity concentration method. This method seperates minerals of different specific gravity by their relative movement in response to gravity and ore or more other forces the latter often being the resistance to motion offered by a viscous fluid, such as water or air.
