This disclosure describes methods to separate solids from liquids in a production facility. A process separates components in the process stream by using a mechanical device to separate the solids from the liquids based on a density difference. The process produces the liquids and solids, which may be further processed to create valuable animal feed products.

There is provided a particle classification system comprising: a classifier including: a vat defining an interior cavity, a feeder conduit upstream of the interior cavity, an overflow conduit in fluid communication between a top of the interior cavity and outside the vat, an underflow conduit downstream of the interior cavity and a controllable underflow valve fluidly connected to a bottom of the interior cavity, the underflow valve controlled to be either in an open configuration in which the interior cavity is in fluid communication with the underflow conduit or in a closed configuration in which the interior cavity is sealed from the underflow conduit; a feed preparation circuit upstream of the feeder conduit; a rejection circuit downstream of the overflow conduit, and a beneficiation circuit downstream of the underflow conduit. There is also provided a method of classifying fluid-borne particles comprising obtaining a feed containing high-density particles.

A coarse coal slime classifying system and method are disclosed. The system includes: a coal slime bucket, an arc-shaped sieve, a hydraulic classifying cyclone, a coal slime centrifuge, and a coal slime chute. The coal slime bucket is connected to a coal slime water incoming pipe. The hydraulic classifying cyclone is connected to the arc-shaped sieve and the coal slime bucket. The arc-shaped sieve is connected to the coal slime bucket and the coal slime centrifuge. The coal slime centrifuge is connected to the coal slime chute and the coal slime bucket. The coal slime bucket, arc-shaped sieve, hydraulic classifying cyclone, coal slime centrifuge, and coal slime chute are arranged to classify coarse coal slime, which improves the product quality and the yield. The system is simple in overall structure, convenient to maintain, and low in cost.

A Cannabis trichome separator. At least one storage vessels are provided, each vessel having an open top and adapted to receive a plant material and chilled or ice water mixture. A mechanism for agitating the mixture is also provided. Another mechanism raises, lowers, and pivots the agitating mechanism, so the agitating mechanism can be placed over the open top of each of the at least one storage vessels. The mixture can be agitated in each of the storage vessels, seriatim. Also disclosed is a method for processing raw plant material. A plant material and chilled or ice water is introduced into each of at least one storage vessels. The agitating mechanism agitates the mixture in a first of the storage vessels, pivoting the agitating mechanism from a first position to a second position, and agitating the mixture in subsequent storage vessels, seriatim.

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.
