Counter-current rotating pan mixers incorporate a Rotor as the primary agitator in the mixing process (shown in the figure below). As discussed in a previous blog post (What is a Counter-Current High Shear Mixer?), global material transport within the pan (mixing vessel) is facilitated through the rotation of the pan itself, which also has the added benefit of producing more homogenous mixes with higher yields. Because the rotor is not needed for global material transport, it can be custom-configured in shape and speed as well as rotational direction to suit a variety of applications. It can change speed and direction at will if so needed. It also allows for fast liquid distribution without the use of atomizing nozzles.read more
Most technical books on mixing equipment rarely include information about Counter-Current High Shear Mixers. Yet, these mixers have been successfully satisfying industrial mixing needs for over half a century. So, how are they different from, and in many ways superior to, other mixer designs?
To best understand the benefits of a counter-current high shear mixer we’ll use the common home kitchen mixer for comparison, as both types of mixers share key components such as an agitator and a vessel where the mixing occurs. In kitchen mixers the agitator is mounted to a motor and the vessel remains locked in place and the rotational axis of the agitator may be fixed or move in an orbit. After mixing our ingredients for some time, we stop the agitator and scrape the bowl to get the unmixed materials near or adhering to the walls to where the agitator runs for better dispersion. We re-start the agitator to finish the mixing step before transferring the wet cake mix to a baking tray, again scraping with a spatula to make sure all the mix is transferred.
Costs to dispose of coal combustion products (CCP), including fly ash and boiler slag, continue to rise in the utility sector, but there are many financial and environmental benefits to converting this waste into marketable end-use products.
Enhanced EPA regulations imposed on power plants require various levels of on-site air pollution control to make air emissions cleaner. What comes out of the air, however, goes into the solid waste, which is costly to dispose of and contributes significantly to landfills. Several other facets must be factored into disposal costs such as transportation and regulatory requirements. It is for these reasons that a growing number of utility companies are turning this costly by-product into a source of revenue.
Fly ash and bottom ash can be used to produce road base materials, manufactured aggregates, flowable fills, structural fills, and embankments. Coal ash is also used to replace natural materials in the production of portland cement. Other applications for CCPs include wallboard manufacturing, roofing tiles and shingles. CCPs are also used for waste stabilization, snow and ice control, soil modification, as mineral fillers, in agriculture and mining and for very specialized uses. For example some CCPs have properties suitable for metal castings in the aerospace and automotive….read more
