The Vital Importance of Dust Collection

and Bulk Material Handling for the Ethanol Industry

CAMCORP led the way for solving fugitive dust emissions for the Ethanol industry more than 10 years ago when ethanol was intended to be a less expensive alternative fuel source. CAMCORP has dust collection solutions installed in more than half of the ethanol plants in the U.S. While the industry is managing through a volatile market, many of the original ethanol plants are still operating and are seeing the impact on their dust collectors from the caustic nature of producing ethanol.

Dust is generated in the grain receiving, grain milling, Dried Distillers Grain with Solubles (DDGS) loadout, and DDGS cooling. Dry milling is the most common process to produce ethanol, however, there are some wet milling processes. In either process, dust collectors remove the dust and other harmful particulates prior to being released into the atmosphere. They also capture dust from the air where the material is being moved either for collection or removal which would otherwise be released within the ethanol plant.

Our diverse product offering for ethanol production starts from the truck or rail car unloading to pneumatic conveying blowers to providing preventive maintenance, inspection, and feasibility studies. And since CAMCORP provides turnkey dust collection systems per application requirements, ethanol plant managers and engineers don’t need to juggle several equipment suppliers.

All fields are required.

Ethanol Applications

Here are common Ethanol applications where CAMCORP has extensive experience:

Receiving & Storage

Almost all dust found in a grain elevator or facility is created at the grain receiving pits. Dust generated by elevator legs, transfer points, and scale bins can be ducted to a single fabric dust collector to reduce housekeeping and the chance of an explosion. Ducting a dust collector to a dryer is also recommended.  When grain is emptied into storage bins and silos, dust is created as the air is displaced as the storage vessel is filled.  Bin vents installed on top of these bins collect the dust as it’s created.

  • Truck and Railcar Loading and Unloading
  • Grain Storage and Transfer
  • Grain Receiving
  • Grain pre-cleaning

Dry Grinding of Corn

As the corn is needed for further processing, it is conveyed to screeners, separators, aspirators, stoners, and scourers all of which create dust that can be ducted to a single or multiple dust collector(s).  Maximize DDGS yield from the hammermill with a dust collector and pneumatically convey it back to the process.

  • Screening and Separating
  • Destoning and Scouring
  • Hammermill Grinding

DDGS Loadout, Cooling, and Storage

A dust collector is critical when loading DDGS into silos, bins, or hoppers. A fine dust cloud is created and a properly sized dust collector for the application will minimize dust from areas that are not rated for combustible dust. In addition to fire and ignition safety, CAMCORP can help to mitigate the loud noise that is created from pneumatic conveyor blowers by providing a blower package complete with a sound enclosure.

  • DDGS cooling interim storage
  • Transferring of large amounts of co-products

Pulse Jet Baghouse

CAMCORP is best known for manufacturing highly specialized Pulse Jet Baghouses including high-pressure, high-vacuum, and explosion-containment designs. CAMCORP also offers a complete range of standard Pulse Jet Baghouses with styles ranging from bottom or top loading bags to walk-in clean air plenums with a variety of inlet configurations.

  • All welded heavy-duty construction
  • Structural supports engineered for location
  • Pressure/vacuum rating +/- 20” W.C. or as required
  • Standard materials of construction: carbon steel, stainless steel, and special alloys
  • Standard electrical: NEMA 4 timer and solenoid enclosures, or as required
  • On-demand cleaning timer board
  • Instrumentation for remote monitoring
  • Explosion venting suppression per NFPA 68
  • OSHA approved service platforms
  • Paint: standard white or envirogreen industrial 2-part epoxy

Vertical Cartridge CAM-AIRO™

The CAMCORP CAM-AIRO is uniquely engineered to solve nearly all dry dust
and fume collection challenges. The vertical design of the CAM-AIRO cartridge
collector optimizes virtually 100% of the filter media area, unlike horizontal designs that can sacrifice nearly 30% of the filter media area over time.

  • All welded heavy-duty construction
  • Housing rated for: +/- 25” W.C.
  • Interior dirty air plenum primed
  • Exterior primed and finished standard white or envirogreen industrial 2-part epoxy
  • Cartridge elements factory installed
  • Standard 80/20 cellulose/synthetic blend filter media
  • Access ladders and service platforms
  • NEMA 4 electrical enclosures
  • Explosion venting or suppression
  • On-demand pulse cleaning optional

Reverse Air

Reverse Air models HVP™ (Medium Pressure) & SWF™ (Low Pressure) dust collector series are the premium choice for processing and manufacturing industries where high air volumes and heavy dust loading are common.

The CAMCORP reverse air dust collector requires no plant compressed air. CAMCORP leads the industry with the most standard sizes and customize-able configurations available to solve virtually all dust collection challenges. Capacities range to over 250,000 CFM.

Bin Vents

Bin vents by CAMCORP have the features and benefits of a pulse jet baghouse and cartridge filter collectors.  Bin vents do not typically incorporate a hopper, but instead are mounted on top of dust generating equipment such as silos, mixers, scale hoppers, and mechanical conveyors.  Instead of discharging the captured dust into a hopper, when using CAMCORP bin vents, the pulse-cleaned dust falls directly back into the process equipment it has been mounted to.  A CAMCORP bin vent dust collector is also designed to meet critical combustible dust standards and can include OSHA approved service platforms and ladders.  The filtering system can be designed to use bags and cages, or cartridges, or tailored to fit your application.

  • Correct selection of filter media to meet the application requirements
  • NEMA 4, 4X, 7, 9 or 12 electrical enclosures on all collectors
  • Explosion venting per NFPA 68
  • Paint selected for the application
  • On-demand cleaning timer board
  • Instrumentation for remote monitoring
  • OSHA approved service platforms

Pneumatic Conveying
& Bulk material handling

Pneumatic conveying is essential for automating manual processes that improve production efficiency, provide quality control and reduce labor costs.

  • Dilute phase pneumatic conveying
  • Filter Receivers
  • Bag dump stations
  • Airlocks
  • Blower packages
  • Central vacuum system
  • Bulk bag unloader
  • Negative airlift
