An apparatus for producing pozzolanic material from consumer waste includes a glass separator unit to remove glass material from the waste and a size reduction unit downstream the glass separator unit. The glass separator unit includes a tubular outer member and an inner helical member extending inwardly from the inner surface of the tubular outer member and defining an open central bore. The tubular outer member and the open central bore define respective coaxial longitudinal axes that are disposed at an angle relative to a horizontal reference plane, with the inlet higher than the outlet. Non-glass/non-ceramic material is output through the open outlet end of tubular outer member utilizing a flow of water. The glass/ceramic material is output to the size reduction unit through the open inlet end of the tubular outer member utilizing the rotating inner helical member of the glass separator unit.

An environment-friendly construction waste treatment equipment for civil engineering is provided, including a main frame, a wringing frame, first fixing columns, a second fixing column, an electric motor, etc. wherein the first fixing column is provided on each of front and rear sides of a left side of an upper portion of the main frame, the wringing frame is provided between the first fixing columns, the second fixing column is provided on rear and left sides of the upper portion of the main frame, and the electric motor is provided on the second fixing column. The electric motor is turned on, the wringing wheels wring the construction waste, the wringed construction waste falls onto the conveying belt, and then is transferred to the filtering plate via the conveying belt. In this way, as the construction waste is conveyed via the conveying belt, the equipment is prevented from being blocked.

A system for processing solid and liquid waste includes a first shale shaker, a second shale shaker, a submersible pump, a centrifugal pump, a first collection tank, a second collection tank, a mud cleaner assembly, a variable frequency drive (VFD) centrifugal solid-liquid separator, and a water clarifying assembly. The first shale shaker is in fluid communication with the second shale shaker through the submersible pump. The second shale shaker is in fluid communication with the centrifugal pump through the first collection tank. The centrifugal pump is in fluid communication with the mud cleaner assembly. The mud cleaner assembly is in fluid communication with the VFD centrifugal solid-liquid separator through the water clarifying assembly. Resultantly, the system discharges a flow of usable water through the VFD centrifugal solid-liquid separator as an initial load of solid and liquid waste is inputted into the first shale shaker.

A lumber use designation system includes a building construction plan that shows the layout, wall thickness, wall height, ceiling angles, etc., of a structure, which are color coded from a series of color codes each corresponding to a preselected, standard board size and length of lumber that should be selected for constructing a particular portion of the structure. The system includes a supply of lumber boards marked with a color code correlating to the color code found on the construction plans. The lumber boards may be imprinted by an ink spray head. A method of installing lumber during the construction of a structure is disclosed.

Apparatus (200) for sorting mixed waste materials, comprising: a housing (260) configured to be vibrated to assist sorting; a screen (210) supported by the housing (260) and having an inlet end (212) for receiving waste materials and an outlet end (214) for discharging at least some waste received at the inlet end (212), the screen (210) comprising at least one portion (220) pivotally coupled adjacent the inlet end (212) to a substantially horizontal axle (222) mounted in the housing (260); and drive means (224,228) configured to pivot the at least one portion (222) of the screen (210) about the axle (222) with a controlled reciprocating action.

The concrete sludge recycling and recovering method comprises a concrete sludge treatment step consisting in separating aggregates, contained in the concrete sludge, from the water loaded with laitance contained in the concrete sludge; a clarification and dewatering step consisting in clarifying the water loaded with laitance which has been separated during the concrete sludge treatment step and dewatering the laitance contained in the water loaded with laitance; a first use step consisting in using the separated aggregates as raw material for concrete manufacturing; and a second use step consisting in using at least part of the clarified water resulting from the clarification and dewatering step as a raw material for concrete manufacturing.

A modular industrial reducing machine is provided. The reducing machine includes a removable cutting tray releasably coupled to a first and second axial endwalls in a base frame. Additionally, the removable cutting tray includes a plurality of non-rotating anvils designed to interact with a plurality of cutters during reducing operation to reduce material in the reducing compartment.

A method and apparatus for producing liquified Alternative Supplemental Cementitious Material (ASCM) from an uncured concrete slurry. Uncured concrete slurry is received into a receiving hopper, diluted with water, and pumped upward through a slurry discharge conduit to an aggregate separator that screens the gravel and sand for separate discharge. The remaining ASCM entrained water flows into a holding tank. The ASCM settles to the lower portion of the holding tank. The holding tank stores the remaining water for re-use diluting uncured concrete slurry. The ASCM is liquified and moved towards the ASCM discharge port by an agitator system located in the bottom of the holding tank. From the discharge, a pump delivers the liquified ASCM through a conduit for discharge. The discharged ASCM can be used as a partial replacement for Ordinary Portland Cement and as an ingredient in flowable fills.
