This paper reports a research project on the removal of sulphur from coal using a combination of gravity concentration and flotation methods. Humphrey's spiral was used Heavy mineral particles sliding down the spiral are extracted by adjustable concentrate ports or cutters located in the inner part of the spiral trough as shown in Fig. 1.Although the opening of the concentrate cutters is a strategic operating variable to control a spiral operation (Tripathy and Murthy, 2012) it was not possible to find a model of the An operational model for a spiral classifier ScienceDirect

Spiral Concentrator TON
Spiral concentrator is an effective, low-cost device for the gravity beneficiation of ores. In a plant operation, it is important to maintain a consistent feed rate to the spiral concentrator banks. The variations in feed tonnages to the spirals should not exceed 10%. It is also important to properly distribute the feed to each individualRake Classifier. The Rake Classifier is designed for either open or closed circuit operation. It is made in two types, type “C” for light duty and type “D” for heavy duty. The mechanism and tank of both units are of sturdiest construction to meet the need for 24 hour a day service. Both type “C” and type “D” Rake ClassifiersTypes of Classifiers in Mineral Processing 911 Metallurgist

Gravity Separation an overview ScienceDirect Topics
Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.Main Classification. Spiral classifier is a common classification equipment used in mineral processing plants. It has the characteristics of simple structure, reliable operation, large processing capacity, stable classification area and high classification efficiency.
