Method of manufacturing a composite granular grouting material
A method of manufacturing a composite granular grouting material according to the present invention comprises: mixing bentonite and auxiliary component; forming spherical composite granules by agglomerating the mixture of bentonite and auxiliary component; drying the formed composite granules; and forming bentonite layer having lower density for forming slurry outside the composite granules by mixing bentonite with the spherical composite granules and agglomerating the same. The grouting material according to the present invention has excellent thermal conductivity and water blocking capability.
PELLETIZED SPENT LIME AND PROCESS OF MAKING SAME FROM WASTEWATER TREATMENT RESIDUE
Water-dispersible pellets are provided that includes spent lime particles present from 80 to 99.5 total weight percent. A binder component is also present from 20 to 0.5 total weight percent. The pellets have a mean pellet domain size. The spent lime particles, and the binder component present in a form such that contact with water causes pellet dispersion into more than 100 pieces. A process of forming spent lime pellets is also provided that include spent lime being dewatered to a free-flowing powder. A binder is then added under conditions to induce agglomeration of the free-flowing powder to the form the pellets. A process of treating a target crop is also provided based on such pellets.

DRY POWDER PROCESSING
A method for forming a pelletised evaporite mineral product, the method comprising: pulverising an evaporite mineral feedstock to form a dry powder, mixing the dry powder with a binder in the presence of a liquid to form an intermediate blend; and processing the intermediate blend using a pelletiser to form pellets principally composed of the evaporite mineral.

APPARATUS FOR POWDER COATING OF PARTICLES
An apparatus for coating pharmaceutical particles such as drug dosage forms or pellets is provided which includes a drum assembly mounted for rotation about a cylindrical axis of the drum and which includes an outer drum section and an inner perforated drum section mounted concentrically on an interior of the outer drum section such that an annular chamber is formed between the perforated inner drum section and the outer drum section. Two or more baffle plates are attached between an outer surface of the inner perforated drum and an inner surface of the outer drum which are configured to act as baffles to restrain or regulate the flow of air which define two or more compartments depending on the number of baffle plates. One end of the drum assembly includes an end plate with a central aperture for use in loading pellets into the drum and provide access to coating constituents that are pumped into the drum interior during the coating process. An air distribution plate is attached at the other end of the drum and has air flow passageways and is interfaced with an air introduction plate having air inlet and outlet passageways. As the drum rotates the air flow passageways in the distribution plate alternately come into flow communication with the air inlet and outlet passageways in the air introduction plate thereby providing a flow path of air into the perforate inner drum and out of the drum assembly.
