Shaking table separation is the gravity concentration process in which the combined action of the asymmetric reciprocating motion of the table and the water flow on the thin inclined layer separates the mineral particles according to their densities on a wide inclined table. Shaking table separation is suitable for separation of fine particle ...

Based on a lab-scale setup, the thermal and flow performances of a single spiral-tube ground heat exchanger under certain operation mode (6 h on and 18 h off) were examined in terms of the influence of Reynolds number (3000–8000) and backfill materials (native sand, and sand/kaolin blend with 5% adding ratio of kaolin). The convective heat …

The spiral conveyor combines the advantages of gentle product handling and vertical transport with vibration technology for bulk products suitable for feeding or in combination with thermal treatment.
