There are a number of design considerations which influence the selection of a suitable pitch and trough shape for a new spiral separator. The separation requirements impose certain constraints on the total design envelope and mutual interaction between some of the requirements and the conflict between metallurgy and materials handling requirements often …

From the detailed literature review above, it is evident that prior studies investigated the thermal performance of spiral/coiled-type vertical GHEs where coils were uniformly distributed (see Table 1).Since the thermal gradient amid GHE working fluid and ground soil around the spiral GHE is higher in the initial part (leading turns) than in subsequent parts (trailing turns), hence heat ...

The spiral separator/ spiral chute is the earliest mining machine. It has been used to classify the granularity of 0.3-0.02 millimeters fine grain like iron, tin, tungsten, tantalum-niobium, gold ore, coal mine, monazite, rutile, zircon, and other metals. The non-metallic minerals have a big enough specific gravity difference.

A spiral classifier and a hydrocyclone are the two main classification equipment. For decades, the spiral classifier has been widely used in ore dressing plants as first-generation grading equipment. As second-generation grading equipment, hydrocyclones quickly occupy a place in the grading equipment of the concentrator due to their small footprint and high …

The spiral chute is mainly composed of six parts: a feeding homogenizer, a feeding groove, a spiral groove, a product intercepting groove, a receiving hopper, and a groove support. When a certain concentration of slurry is fed into the upper part of the spiral ore separator, the slurry rotates downward along the spiral groove.

Only enough water is necessary to keep the solids in full teeter. As the sands accumulate in the classifier pockets the effective density of sand-water mixture increases and thumbscrews on the valve rod assemblies may be adjusted to discharge sand from each compartment as required.
