The comparison of the performance of the Stripa with that of the Baum jig indicates that Stripa can be used in coal preparation circuits as an alternative to jigs in the size range of − 100 + 10 mm. Simplicity, low initial investment, and low operating and maintenance costs make the Stripa a plausible candidate for coarse coal cleaning.
The Batac jig can treat coarse as well as fine sizes of coal. In other words, it can handle any of the sizes now being washed in the various types of Baum jigs installed in this country. The standard Baum jig uses either plunger-type air valves or rotary valves. The Batac jig uses flat discs which are electronically and pneumatically controlled.

These two actions are combined in a Jig by slurry pulses generated mechanically or by air. Coal Jigs (Baum type) Suitable for coarse load, feed size range maximum 175 - 200 mm (7 - 8 inch), minimum 40 - 60 mm (1.5 - 2.5 inch). • Air pulsation type • Two or three products • Automatic discharge
Jigs represent one of the earliest types of process equipment employed in mineral separation. Jigging became a popular and efficient method for coal cleaning over the last century. The underbed – pulsated BATAC jig is newly developed and has a significant improved performance compared to the BAUM jigs.
At the heart of the plant is a PLC Baum Jig Wash box that does the majority of coal cleaning. The clean coal is then wet screened at 15 - 100 mm and 6 - 15 mm.To . History of coal .

This chapter discusses the cleaning of coarse and small coal, defined as particles greater than approximately 1.0 mm in size. 1 Section 10.1 discusses the layout of a generic coal handling and preparation plant (CHPP) with parallel streams of material in different size fractions, and introduces the technology options available in each size range.
The jig is normally used to concentrate relatively coarse material. Good separation is possible if the feed is closely sized (e.g. 3 – 10) and if the sp. gr. difference is large. Many large jig circuits are still operated in the coal, cassiteriite, tungsten, gold, barytes and iron-ore industries.
Distribution curves for 81 sets of coal cleaning data covering six coal washing methods were studied using six different mathematical models. The importance of selecting a distribution curve model based on the shape characteristics of the curve as well as the normal statistical tests is illustrated. 8 references.
