For Concrete Batch Plants
Griffin
Environmental offers numerous models within the Clean-A-Batch system capable of
providing dust free operation for your batch plant. Whether your needs are for
Transit Mix (dry), Central Mix (wet) or Combination; whether it is high or low
production; a stationary or portable plant; we have the equipment to give you
the assurance of meeting today's environmental standards.
There are
three steps during the batching operation where dust must be controlled. These
three are the silo filling, weigh batching and truck loading. The company offers
two alternatives for your equipment selection. There can be a single Central
Baghouse which draws the dust from each of these points, or smaller Individual Dust Collectors located at the points of dust
generation.
Your local Griffin dealer or our factory engineers are
available to help you decide upon the most effective and economical approach for
your particular plant. Either way, these systems are capable of dust control far
exceeding the 99% efficiency required for clean operations.
