A lead needle and lead slime separator for treating thin lead grid of waste lead-acid storage battery, includes: a barrel body, corrosion-resistant and wear-resistant balls, a feed device, a bracket device, a discharge device and a driver. A feed hole is arranged at one end of the barrel body, a discharge port is arranged at the other end of the barrel body. The feed device is mounted at the feed hole, and the discharge device is mounted at the discharge hole. The bracket device is connected to the barrel body, the driver is connected to the barrel body. The corrosion-resistant and wear-resistant balls are arranged in the barrel body. The separator can make the thin lead grid separation complete, clean and impurity-free. It does not need to be melted at high temperature in the melting furnace.

A method for preparing clean aggregate from a waste stream including sizing the incinerator combined ash to recover a first material; wet screening the first material with a first screen to recover the material of disparate sizes; and processing each of the groups.

A slurry handling apparatus includes at least one reception hopper includes a base, a rear wall and opposing side walls, and an opening provided in the base. Slurry delivered into the reception hopper from a tanker can pass through the opening in the base, and a respective first dewatering screen having an apertured screening deck is located beneath the at least one reception hopper so that slurry passing through the opening is delivered onto the deck of the respective screen, with undersize material and water passing through the apertures of the deck to be received within a sump, and with oversize material passing over the deck to be discharged from a downstream end of the deck.

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 method for converting municipal solid waste to a stable solid fill-material (backfill) in the form of a multiplicity of compacted pieces, the method including mechanically reducing solid-waste piece size to form a solid-waste stream, heating the solid-waste stream and thereby killing bacteria in such stream, adding an antimicrobial agent to the solid-waste stream, and pelletizing the solid-waste stream.

Apparatus and method for recovering precious metals from contaminated cement, comprising, in order of process, a crusher, in which a cement-metal conglomerate is placed, a sieve, a dispenser, a first container, suitable for collecting the metal on the bottom through the action of a magnetic stirrer, an expander, a second container, a drainage tank, and a sieve. The present invention relates in particular to the recovery of precious metal from the batch of cement contaminated by precious metals, such as platinum, rhodium, gold, or silver. In the production of glass fibers for reinforcement, dies made of an alloy of precious metals, in particular platinum and rhodium, are used. These dies are supported by a special cement structure. During the months of production life of the die, part of the precious metal diffuses into the cement on account of the high temperatures. Given the value of the metals, it is economically advantageous to recover them from the supporting cement at each change of the die.

The subject matter proposes an automated compact depackaging system. The depackaging system includes a receiving hopper, a vertical depackager, dumpsters and a sedimentation unit. The vertical depackager simultaneously removes and cleans packaging materials and the materials that exit the system are clean and organics free. The system also includes a dosing device for dosed discharge of waste or bulk material into the hopper. The hopper may also receive the organic wastes directly from trucks. The dosing device is fitted with metal to identify metals in the bulk material. The assembly includes a grabber on an overhead crane to pick up the metal piece once located. The hopper comprises air doors and air roofs to keep off from smell spreading into the room. The organics that are extracted from the waste are free of plastics and other packaging material.
