摘要： The invention relates to a method and system for the environmental remediation of materials that are contaminated with heavy minerals, such as heavy metals. The invention finds utility in removing heavy minerals from materials such as soils, sediments, mine tailings and ores. The invention provides a means for removing heavy minerals from contaminated materials without the use of water while reducing the generation of dust. Thus, the invention provides an environmentally friendly method for the remediation of sites that are contaminated with heavy minerals.

摘要： The present invention provides a fiber raw material processing system and its operation method. The fiber raw material processing system is composed of a cutting module, a bulk pulping module, a salt slurry processing module, a pressure screen, a separation module, an inclined screen module, and an extrusion module and a recycling module, which are connected in series. The operating method of the fiber raw material processing system is to process absorptive articles such as diapers or sanitary napkins, etc., which are retained and made into fluff fiber raw materials through the purification and separation steps performed by the modules of the fiber raw material processing system.

摘要： An apparatus for processing a waste battery is proposed. The apparatus includes a conveying unit having a conveying belt rotated by a plurality of rotating shafts which are rotated to convey the supplied waste battery in one direction, a pulverizer disposed on a position along a travelling direction of the conveying unit to pulverize the waste battery, a heater disposed on a downstream side of the pulverizer to heat dust formed by the pulverizer, a collector collecting the dust which passes through the pulverizer and the heater, a filter part filtering a pulverized material of the collector, a mixer supplying an additive to the dust discharged from a discharge pipe of the filter part, and a compressor compressing a mixture mixed in the mixer.

摘要： The present invention relates generally to the field of waste processing. The method comprises separating waste into at least two parts, comprising: (i) mainly food waste (fines) and (ii) mainly paper and other recyclable material (overs). The overs are pulped and washed to obtain a cellulose-rich biomass and the fines are optionally processed separately to recover a cellulose-rich biomass and the cellulose-rich biomass from both the fines and the overs may be combined.

摘要： 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.
