Provided is a building material manufacturing apparatus and a building material manufacturing method that are suitable for efficiently manufacturing a building material while suppressing clogging of a sieve portion for sieving the building raw material. The building material manufacturing apparatus of the present invention includes, for example, a sieve portion 10 and a receiving tool 30. The sieve portion 10 includes a receiving and sending sheet 11 with no sieve openings, onto which the building raw material M is dropped, and at least one sieve sheet 12 with sieve openings that is located below the sheet. The receiving and sending sheet 11 and the sieve sheet 12 can perform undulating motion, are inclined, and are arranged side by side in the inclination direction. The receiving tool 30 is for receiving the building raw material M that has passed through the sieve openings of the sieve portion 10. In the building material manufacturing method of the present invention, for example, in a state in which the receiving and sending sheet 11 and the at least one sieve sheet 12 are performing undulating motion, the building raw material M is dropped onto the receiving and sending sheet 11, moved from the receiving and sending sheet 11 onto the sieve sheet 12, subjected to sieving by the sieve sheet 12, and the portion that passes through the sieve openings of the sieve sheet 12 is accumulated on the receiving tool 30, whereby a mat with at least one layer is formed.

A sieve device for fine-cleaning of grainy material after preliminary cleaning in an aspirator, having an inclined body made of separably integrated frames, in which replaceable stationary sieve are placed one below the other, the upper sieve having openings corresponding to the size of the grain, and the lower sieve having openings smaller than the grain, while a charging hopper is mounted in the upper, peripheral part of the body above the upper sieve. The each sieve consists of cascading identical flat sieve segments connected in sequence by z-shaped connectors, so that the planes of all sieve segments are parallel and above each z-shaped connector there is a set of plates mounted pendulously and independently on a bracket mounted on the frame of the body above the sieve, parallel to the z-shaped connector, the combined width of the plates in the set corresponding to the width of the sieve segment.

An apparatus having a screen frame with a first screening surface and multiple openings is disclosed. The openings can be bounded by at least one mating surface. One or more screen filter unit having a second screening surface can be disposed in one of the openings of the screen frame. The one or more screen filter unit can have one or more sealing surface that can be coupled to the at least one mating surface of the screen frame.

An apparatus and method for facilitating recovery of lubrication beads is provided. The apparatus includes a hydrocyclone, for separating drilling fluid into a high density stream and a low density stream containing a major portion of the lubrication beads; a receiving pump, for pumping drilling fluid to the hydrocyclone; a discharge pump, for pumping the high density stream from the lower end of the hydrocyclone to further processing; and a hose for flowing the low density stream from the upper end of the hydrocyclone to the cleaned fluid handling system. A method for integrating the apparatus for facilitating recovery of lubrication beads from a drilling fluid into a solids control apparatus includes positioning an end of a first hose to receive the drilling fluid; arranging an end of a second hose in communication with the first shaker's filter screen; and setting an end of a third hose to empty into the cleaned fluid handling system. A method for facilitating recovery of lubrication beads from a drilling fluid by a shaker system includes receiving drilling fluid in a hydrocyclone; separating the drilling fluid into a high density stream and a low density stream containing a major portion of the lubrication beads; and flowing the high density stream to a first shaker of the shaker system, and directing the low density stream to a second shaker of the shaker system.

A disclosed screening apparatus includes a subgrid, and a screen element attached to the subgrid via laser welding at a plurality of attachment positions such that, under vibrational excitation, the screen element has a pre-determined profile of vibrational motion relative to the subgrid. The screen element may be attached at a maximal number of attachment locations to the subgrid to minimize relative motion of the screen element and the subgrid under vibrational excitation, or the screen element may be attached a sub-set of the maximal number of attachment locations to allow vibrational motion of the screen element relative to the subgrid. A disclosed method may include attaching a plurality of screen elements to a respective plurality of subgrids, attaching the plurality of subgrids to one another to form a screening pre-assembly, and cutting edges of the screening pre-assembly to form the screen assembly having a perimeter with a pre-determined shape.

A screen assembly for use in vibratory separators, e.g., shale shakers. The screen assembly has a support with first and second sides, and support surfaces bounded by and connected to at least a portion of the first and second sides. Overlying and adhered to at least portions of the support surfaces is a screen which has alternating planar and undulating portions of screening material.

A sieve bend can include a support structure supporting a screening arrangement. The screening arrangement can include a first screening segment having a first screening element configuration and at least one further screening segment having a second screening element configuration different from the first screening element configuration.

A method for recording motion patterns (210) of tumbler screening machines (410) is disclosed, wherein the method comprises applying of an active or passive optical marking (500, 510) at a tumbler screening machine (410), recording an image of the optical marking (500, 510) during operation of the tumbler screening machine (410), establishing image data for a motion curve (200), and internally or externally evaluating the recorded image data and determining machine parameters and diagnosis data. Furthermore, a device for recording motion patterns (210) of tumbler screening machines (410) is introduced.

The present invention is directed to a drilling fluid reclaimer The reclaimer has at least one adjustable screen assembly for providing a leveling filter for reclaimed drill fluid. Used drill fluid is placed at the screen assembly at the front the of the screen assembly. The at least one screen is vibrated to separate large particulate matter from liquid drilling fluid. A second screen is provided for additional filtering. Large particulate matter is expelled by a chute at the back of the screen assembly. Drilling fluid passing through the screen is reclaimed for use with a drilling system.

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.
