Abstract: A roasting drum has a main body and at least one opening formed through the main body. The main body has a first end, a second end opposite the first end, and multiple drums. The multiple drums are mounted around one another in sequence, are fastened to one another, and communicate with one another. Each one of the multiple drums has a blending blade formed on an inner surface of the drum. The blending blade is spiral and extends from the first end toward the second end. The blending blade of one of the multiple drums twists along a clockwise direction from the first end toward the second end. The blending blade of another one of the multiple drums that is mounted around the drum twists along a counter-clockwise direction from the first end toward the second end.

Abstract: The invention relates to a method for adjusting concrete rheology requiring only that load size and target rheology value be selected initially rather than requiring inputs into and consultation of a lookup table of parameters such as water and hydration levels, mix components, temperature, humidity, aggregate components, and others. Dosage of particular rheology-modifying agent or combination of rheology-modifying agents is calculated based on a percentage of a nominal dose calculated with reference to a nominal dose response (“NDR”) curve or profile. The NDR profile is based on a correlation between a rheology value (e.g., slump, slump flow, yield stress) and the rheology-modifying agent(s) dose required to change rheology value by one unit (e.g., slump change from 2 to 3 inches) such that exemplary methods can employ corrective dosing based on the NDR and the measured deviation by the system.

The mixer employs a straight bulk cement inlet, five annular recirculation jet and five annular water jet orifices located downstream of the recirculation jets so that all of the jets discharge at an angle towards the mixing chamber. The five annular recirculation jets are located in alternating longitudinal alignment within the mixing chamber relative to the five annular water jets. This five jet, intersecting flow design allows for more thorough wetting of the cement powder with a smaller, lighter, less expensive and more durable mixer that is less inclined to foul and easier to clean.

Abstract: A process is disclosed for preparing a silver halide emulsion comprised of serially receiving a silver halide emulsion at an upstream location, supplying the silver halide emulsion in a further prepared form at a downstream location, and transporting the silver halide emulsion between the upstream and downstream locations while it is being further prepared. The silver halide emulsion is divided into discrete segments as it is received at the upstream location. The discrete segments of the silver halide emulsion are transported between the upstream and downstream locations in the sequence of their formation. The emulsion can be finished as it is transported to the downstream location. The silver halide grains can be shelled during transport. In still another application a converted-halide emulsion can be formed during transport to the downstream location.
