Embodiments of the present disclosure provide for systems, apparatuses, and methods of securing screen assemblies. Embodiments include a system having a compression assembly with a compression pin and a pin assembly having a pin. The compression assembly may be attached to a first wall member of a vibratory screening machine and the pin assembly may be attached to a second wall member of the vibratory screening machine opposite the first wall member such that the compression assembly is configured to assert a force against a first side portion of a screen assembly and drive a second side portion of the screen assembly against the pin of the pin assembly. The pin assembly may include a pin that is internally or externally mounted and that is adjustable and/or replaceable.

Vibratory separator screens separate solids and/or fluids, methods form said screens and vibratory screen apparatuses utilize said screens. The vibratory separator screens, methods and apparatuses have a mesh portion having a first side of the mesh portion and an opposite second side of the mesh portion, a first hem crimp affixed to the first side of the mesh portion, and a second hem crimp affixed to the second side of the mesh portion.

A screening machine includes wall members, screen assembly guide members, a screen assembly and a compression assembly. The screen assembly includes a frame with a plurality of side members and a screen supported by the frame. The compression assembly is attached to at least one wall member and forms the screen assembly into a concave shape.

A flip-flow screener machine includes a carrier frame with primary, drive-induced vibration, to which a vibrating frame is coupled in a freely oscillating manner by means of elastic transmission elements and is excited and set to vibrate secondarily by the carrier frame via said transmission elements, transverse carriers being arranged on the carrier frame and on the vibrating frame, a transverse carrier on the vibrating frame lying downstream of a transverse carrier on said carrier frame, with a flexible screen bottom being arranged between two transverse carriers and detachably secured to said transverse carriers, each of the screen bottoms including at least one undercut portion by means of which they can engage behind an undercut on the transverse carrier, and two adjacent screen bottoms abutting one another directly at their front ends.

Vibratory separator screens separate solids and/or fluids, methods form said screens and vibratory screen apparatuses utilize said screens. The vibratory separator screens, methods and apparatuses have a mesh portion having a first side of the mesh portion and an opposite second side of the mesh portion, a first hem crimp affixed to the first side of the mesh portion, and a second hem crimp affixed to the second side of the mesh portion.

A building material manufacturing apparatus includes a sieve portion 10 and a receiver 30 that receives a building raw material M that has passed through the meshes of the sieve portion 10. The sieve portion 10 includes a series of sheets that are each capable of performing a wave motion when the apparatus is operating, that have an inclination, and that are arranged in a direction of the inclination. The series of sheets include a sieve sheet 12 and a sieve sheet 13 positioned below the sieve sheet 12. In the sieve sheet 12, meshes having an identical size are arranged at a regular pitch in a sheet width direction W. In the sieve sheet 13, meshes having two or more different sizes are arranged or a mesh region R1 and a non-mesh region R2 are arranged, in the sheet width direction W. The receiver 30 is movable below the series of sheets. The building material manufacturing method includes, by using the apparatus, forming a mat on the receiver 30, the mat including a first layer formed from a part of the building raw material M that has passed through the meshes of the sieve sheet 12 and a second layer formed from a part of the building raw material M that has passed through the meshes of the sieve sheet 13.
