摘要： Methods, systems, and apparatus for winnowing. In one aspect, a method includes loading an initial material into a winnowing system via a feed member; feeding the material into a fluidically accelerated winnowing cavity, where the initial material impacts at least one plate member to yield chaff material and processed material, and where the processed material and the chaff material circulate in the winnowing cavity; and separating the chaff material and the processed from the winnowing cavity based on density. Other aspects include yielding intermediate material, where the intermediate material reimpacts the at least one plate member until yielding chaff material and processed material, preprocessing the initial material, controlling the flow of initial material into the winnowing cavity with a feed gate, where the chaff material egresses the winnowing cavity via a chaff chute, where the chaff material collects in a collection cavity, and/or more.

摘要： The invention relates to a method and system for the environmental remediation of materials that are contaminated with heavy minerals, such as heavy metals. The invention finds utility in removing heavy minerals from materials such as soils, sediments, mine tailings and ores. The invention provides a means for removing heavy minerals from contaminated materials without the use of water while reducing the generation of dust. Thus, the invention provides an environmentally friendly method for the remediation of sites that are contaminated with heavy minerals.

摘要： A vertical roller mill provided with a cyclone-type fixed separator that separates fine powder and allows the separated powder to flow out to the outside, the cyclone-type fixed separator being provided inside a housing, wherein the fixed separator is configured so that a solid-gas two-phase flow is introduced from a fixed blade inlet window opening on a cone into the inside and the solid-gas two-phase flow is swirled using a fixed blade attached in the inside vicinity of the fixed blade inlet window, whereby the fine powder flows out to the outside from a pulverized coal outlet in an upper portion of the vertical roller mill through the lower end side of an inner cylinder provided inside the cone, a surface layer in which the rebound coefficient of collided particles is higher than in an iron plate surface being formed in the outer surface of the inner cylinder.

摘要： An aerodynamic recirculating separator of bulk materials that includes an air blower capable of forming an air stream, an outlet stream directing means, a separation chamber including two inlets and two outlets, a loading hopper, at least one discharge channel, a return air duct including a plurality of turning portions, and at least one residue collection chamber. An outlet of the air blower connects to the first inlet of the separation chamber, an outlet of the loading hopper connects to the second inlet of the separation chamber, the first outlet of the separation chamber connects to the return air duct, and the second outlet of the separation chamber connects to the at least one discharge channel. The air blower, the separation chamber, and the return air duct are consecutively connected so as to form a recirculation channel. The separator forms a material particle flow from the loading hopper to the separation chamber, to distribute commercial particles by their aerodynamic parameters in the separation chamber as the commercial particles fall from the loading hopper and are blown by the air stream formed by the air blower, and to remove the commercial particles through the at least one discharge channel. The separator forces remaining material particles into the at least one horizontally flared portion, directs at least a part of the remaining material particles into a residue collection chamber by way of gravity, and injects air into the separation chamber via the discharge channels. The first downstream horizontally flared portion includes a downwardly curved bottom wall and an opening in communication with said flared portion and the external environment. The opening is disposed in a smooth turn zone from said flared portion to the first of the plurality of turning portions, which has an upward turn.
