The present disclosure relates to the field of mineral processing and separation, and in particular, to an underground coal hypergravity field separation system and a separation process. The separation system includes a grading hydrocyclone group, hypergravity field separators, feeding pumps, and conveying pumps. Coal collected underground is graded through a grading hydrocyclone first, then is fed into the hypergravity field separators for separation, and finally, is conveyed to a next link for dehydration through the conveying pumps. The separation system of the present disclosure has less supporting equipment, small floor area, and no complex pipeline, and is suitable for a downhole operation. In addition, the hypergravity field separators can provide a high-strength centrifugal acceleration, which can realize rapid separation of coal gangue particles in a radial direction and a tangential direction, and realize effective separation of fine coal gangue particles.

The present application is related to the process of automation of separation by identification, classification and quantification of grains and their possible pertinent materials through equipment that performs such events, aiming at the automation of the whole chain of separation, identification and classification. grain, thus eliminating the human action of the process and thus avoiding errors related to human interaction in the process. This process has 4 steps, as follows: grain and impurities entering the equipment; separation of impurities and grains: grain processing and qualitative and quantitative identification of grains and impurities. The process and equipment can be applied to the separation by identification, classification and quantification of grains such as soybeans, corn, among others, and their possible pertinent materials.

A system for separating materials from a waste stream includes multiple processing units arranged linearly, each configured to employ a density separation process. The system incorporates a paddlewheel or similar agitator in one or more of the units, thereby providing enhanced control over the agitation and forces used to separate heavier fractions from lighter fractions. By adjusting paddlewheel speed and other operational parameters, residence times in each unit can be optimized to maximize overall separation efficiency.

There is provided a system for treating a combination of a liquid and granular matter, which granular matter is larger than or equal to a minimum grain size and comprises two or more types of granular matter with different densities, wherein at least two of the different types of granular matter have densities being larger than the density of the liquid. The system comprises a stratification machine with a stratification or sorting chamber for holding the combination of liquid and granular matter, which stratification or sorting chamber has one or more side walls. The stratification machine also holds a movable plate arranged within the stratification or sorting chamber, where the moveable plate has sieve openings smaller than the minimum grain size of the granular matter to be treated to thereby maintain the granular matter above or on top of the movable plate. The stratification machine further holds a drive system for moving the movable plate in vertical upwards and downwards movements within the stratification or sorting chamber to thereby exercise or treat the granular matter within the liquid. There is also provided a method for treating the combination of a liquid and granular matter. The granular matter may include or consist of polymer granular matter.

The separation of materials according to their density is carried out in a fluid bath by floating ground light materials and carrying same over an overflow, as well as depositing ground heavier materials on a horizontal sieve base within the fluid bath. In order to improve the floating of the lighter materials, a displacement body is cyclically sunk into the fluid bath. The fluid bath is supplied with additional fluid in a synchronous manner with the cyclical movement of the displacement body. A control device for supplying the fluid can also be connected to pressure sensors or the drive of the displacement body.
