DEVELOPMENT OF HYDROHOISTS: SLURRY FEEDERS WITHOUT CONTAMINATION
Hydrohoists are often called lock-hopper feeders and are used for slurry transport, with minimum erosion in the equipment. However, contamination due to direct contact between mixture and clear liquid (such as clear water) had been a shortcoming of the hydrohoist. The author studied the performance of contamination of the hydrohoist, developed by new types of hydrohoists and came to the following conclusion: 1) The hydrohoists using gravity feed cannot prevent contamination. 2) In the horizontal hydrohoist adopting forced flow and special devices, the contamination of clear liquid by slurry is negligible. This type is fit for transport of coarse material. 3) In the vertical hydrohoist adopting separator and special devices, contaminations both of clear liquid and of mixture are negligible. This type is fit for transport of fine slurry.
