A drum (100) for sorting objects is provided. The drum has a cylindrical shape, and said drum (100) comprises a cylindrical body (101), with an inner and an outer envelope surface. A plurality of pockets (104) are arranged on the inner envelope surface of the cylindrical body (101), and said pockets (104) are provided with openings (105) opening up into the outer envelope surface. At least one groove (106) is arranged on the outer envelope surface, said groove (105) interconnecting at least two openings (105). A machine (1000) comprising such a drum (100) and a method for manufacturing such drum (100) are also provided.

According to one aspect, a diffuser apparatus includes a first pipe having a first plurality of openings formed therein, the first pipe defining a first passageway that is adapted to receive a first portion of debris that is discharged from a well; a first housing within which the first pipe extends, the first housing comprising a first wall and a first outlet formed therein; and a first region formed between the first pipe and the first housing, the first region in communication with the first passageway via the first plurality of openings; wherein the first plurality of openings are circumferentially and axially spaced along the first pipe to pass the first portion of the debris from the first passageway to the first region; and wherein the first outlet is sized such that the first portion of the debris exits the first region via the first outlet.

A profiled strainer bar has a base region and a head region. A straining slot or a straining gap is produced between flanks of the straining slot at the head region. Each flank at the head region has a radius with a common center on the upstream and downstream side. A strainer, preferably in the shape of a strainer basket, has straining slots or straining gaps formed between profiled strainer bars. The strainer bars have a geometry at the strainer bar base region with the geometry being adapted to receiving recesses of support elements and being received in the receiving recesses. The strainer bars are permanently secured to the receiving recesses. The strainer bars are profiled such that each flank on the head region of the strainer bar has a radius with a common center on the upstream and downstream side.

Disclosed is a tool for cleaning debris from sand when pulled on the sand by a user which has a sieve and a handle, and which sieve is generally semi-cylindrically shaped, and has a pair of balloon tires rotatably mounted to the frame of the sieve, which tires are mounted colinear with the center of mass of the sieve. The frame of the sieve has a crossbar which is slightly off-center from said open mouth of said sieve, forming openings on either side of the crossbar, and allowing the handle, which is disposed on the crossbar, to effectively and easily rotate the sieve by being offset from the center of mass and center of rotation of the sieve. The handle is offset from the plane of the mouth of the sieve so as to further facilitate rotation and dragging in an in-use or not-in-use manner selectively.

A rock separator for separating rocks from soil, where the rock separator includes a mounting plate a plurality of elongate tines secured to the mounting plate, where the plurality of elongate tines define a curved shape across the mounting plate, a plurality of support members laterally joining the plurality of elongate tines and an attachment bracket on the mounting plate for releasably mounting to a machine. The mounting plate has a first major surface and a second major surface opposite the first major surface. The attachment bracket is attached directly to the mounting plate, where the plurality of elongate tines do not move relative the attachment bracket.

A rotary separation apparatus is deployed in a process for separating resinous trichomes rich in flavoring, aromatic and/or medicinal components produced in plant trichome glands from unwanted plant matter. A liquid freezing agent is introduced into a container of the plant matter to fragment the undesirable matter while the desired portion rich in trichome remain intact.

A stone sieve assembly includes a cutting blade, a back plate, and a plurality of bars. The plurality of bars are spaced apart from one another and extend between the cutting blade and the back plate. The plurality of bars have a leading section positioned proximate the cutting blade and a trailing section positioned proximate the back plate. The trailing section tapers inwardly as it approaches the back plate.

Methods and apparatuses for screening are provided. Embodiments include a screen basket apparatus for screening material, comprising a grid frame having a plurality of openings arranged in a lattice and a plurality of screening cartridge assemblies affixed to the grid frame to cover the respective openings of the grid frame. The screening cartridge assembly includes a case and a screen assembly fitted into the case, and may be affixed to a set of transversal member of the grid frame. The case may be formed of a single injection molded piece integrally formed by injection molding one of a polyurethane or a thermoset polymer. The screening elements together form a generally continuous screening surface across the exterior of the grid frame, which reduces blinding and is resistant to wear and tear.
