A close-tolerance gear pump coupled with a properly designed drive system will result in consistent, repeatable delivery of sand. There are fit tolerances for any gear-style pump that must be maintained in order to allow the parts to move against each other.
Mixing of any material or combination of materials is accomplished by moving the materials together against themselves. The mixer, regardless of design or materials to be blended, exists only to accomplish a uniform distribution of the components. Whether mixing concrete, polymers, liquids, powders, or silica sand with differing chemical system, the purpose of the mixing machine is to move the materials against themselves. In our industry we are mixing sands with very small amounts of ...
