Shaving device handle with hole

A mobile system and process for manufacturing cement additives and/or concrete admixture products comprises at least two tanks each containing a different raw material for manufacturing cement additives or concrete admixtures; a frame for mounting and transporting as an integral unit at least two pumps operative to transfer the raw materials into a blender which mixes the raw materials together to provide a cement additive or concrete admixture for dispensing at the destination site, which could be the manufacturer's new or remote manufacturing site, or even a customer's site such as a cement plant or a ready-mix concrete plant. The frame can be placed upon or attached to wheels, as in a truck or trailer frame, and the tanks may also be placed on or secured to the truck or trailer frame. A preferred skid-mounted system comprises pumps, valves, meters, and a computer processor unit which can control the equipment and permit adjustments to be made at the destination site. Tanks of raw materials may be transported to a destination site together with or separately from the frame-mounted equipment, and finished products can be blended and adjusted on site by computer-controlled operation drawing upon inputted information parameters such as the quality of limestone, cement, aggregates, water, and also by drawing upon customer profile information (desired product blends, performance features, etc.) at the destination site.

Mobile cement additive and concrete admixture manufacturing process and system

A mobile system and process for manufacturing and delivering concrete admixture finished products comprises: providing in separate transport tanks mounted on a vehicular frame at least two raw admixture materials (components); and blending together said at least two concrete admixture raw materials to provide a finished admixture product, whereby a finished admixture product is provided at a customer site, such as at a customer's mixing plant. Preferred processes and systems of the invention employ pump means for feeding admixture raw materials from the transport tanks to a blender, metering means for measuring the amount or rate of raw materials fed into the blender, and quality control units for monitoring physical characteristics of the finished product being delivered. Quality control units, such as devices for measuring certain physical properties such as total solids, specific gravity, pH, viscosity, volume, or other properties, may be employed to monitor, control, and track the nature of finished admixture product as they are made and/or dispensed, and even of the individual raw material components being processed in the system.
