Abstract
An atmospheric storage mechanical weigh batch blend plant is shown with atmospheric storage for providing a dry, pre-blend, oilfield cement ready for mixing at the wellhead for slurry injection into a well head upon adding the proper amount of water and other fluids. The batch blend plant has three separate weighing mechanisms for (a) larger or bulk quantity materials, (b) intermediate quantities of materials, and (c) small amounts of additives to be included to the mixture. The entire weigh batch blend plant can be disassembled and moved. A pneumatic system is used to move the materials and mixture.
