摘要:
There is provided a purification apparatus that packages two apparatuses that respectively perform separation treatment and purification treatment into a single apparatus, to reduce a size of the apparatus and facilitate easier transportation to the site, and to improve a treatment amount of contaminated earth and sand per unit time. The purification apparatus includes a drum rotatable around an axis, a sieve having a cylindrical shape and being fixedly accommodated in the drum, a first blade having a spiral shape and being provided between the drum and the sieve, and the second blade having a spiral shape and being provided in the sieve. In the purification apparatus, soil charged into the sieve is separated with the sieve, only the contaminated earth and sand are gathered in a treatment tank between the drum and the sieve, and a chemical agent is introduced into the treatment tank for the purification treatment.

A mixer including a rotatable mixing container including a container drive, a mixing head attached in the mixing container, a rotatably mounted mixing tool, and a tool drive to drive the mixing tool. The mixing tool includes a shaft and a frame arranged concentrically around the shaft. The shaft and the frame are interconnected by at least two circulating elements. The at least one shear pin is arranged on the frame and is configured to be guided during an operation by at least one shear groove disposed in the mixing head.

A high performance green concrete mixer and a high performance mixing method of green concrete are provided. The high performance green concrete mixer includes a pan mixer, plural drum mixers and a funnel. Each of the drum mixers is inclined relative to the pan mixer, while the funnel is connected between the pan mixer and the drum mixers.

Disclosed is a method for removing unburned carbon from fly ash at low cost and within a short time. The method comprises the steps of adding a collecting agent to fly ash directly, agitating/mixing the mixture in a mixer (5), adding water to the resulting mixed material in a mixing vessel (7) to yield a slurry, applying a shearing force to the slurry in a submerged stirrer (9), and performing flotation separation of unburned carbon in a flotator (15).

A concrete batch plant (1) includes a frame (2), a cement supply (3), an aggregate supply (4) and a transit mixer drum (6) having an open end and a closed end. The drum is pivotally coupled to the frame for movement between a first maintained position in which the open end is positioned to receive cement from the cement supply and to receive aggregate from the aggregate supply and a second maintained position in which the open end is positioned to discharge mixed cement and aggregate.

A continuous feed mixer for cement or other mixtures includes a mixing tube which is inclined downward from a feed end to a mixing end. Cement solids are deposited at the feed end. Water is introduced at various locations along the length of the mixing tube to provide a proper proportion of solids and water. The mixing tube is rotated to provide the desired mixing process. A scraper is positioned within the mixing tube to remove material from an inner wall of the mixing tube during the mixing process.
