Corn Cob Blast Media

Corn Cobs

Agricultural media offers a softer, more environmentally friendly alternative to other media types such as steel, plastic or aluminum oxide. Milled corn cob is a popular choice for various blasting, tumbling, polishing, deburring and deflashing applications. A mild abrasive, corn cob blasting media is available in fine, medium and coarse grains as well as in treated formulas where the media is blended with additives to enhance its cleaning and polishing properties.

Key Corn Cob Media Properties and Characteristics

Corn cob media typically exhibits a blocky or angular shape and features a Mohs hardness in the range of 2.5 to 3.5. Perhaps the most unique corn cob polishing media property is its ability to absorb many times its own weight in moisture, making it an excellent choice for drying and degreasing applications.

In addition, corn cob offers strong resistance to attrition — despite its light weight and seemingly fragile composition, it provides remarkable durability and can withstand the rigors of heavy-duty finishing processes.




Corn Cob Media Applications

Corn cob is able to clean and polish delicate surfaces such as brick, stone, glass and wood, as well as aluminum, acrylics and precious metals such as gold and silver. It is also frequently used in the final stage of the tumbling process to enhance the appearance of the finished product, and in various parts drying processes. Examples of specific applications include:

  • Deflashing, deburring, burnishing and polishing of metal stampings, die castings and molded plastics
  • Jewelry polishing
  • Surface preparation prior to painting
  • Cleaning log home timbers prior to sealing
  • Cleaning boat hulls
  • Removing soil and grease from the ceilings of manufacturing facilities
  • Cleaning and degreasing heavy machinery such as generators, motors, transformers and insulators
  • Pump and pipe cleaning

What Are the Benefits of Using Corn Cob Blasting/Polishing Media?

The many corn cob media benefits include:

  • Affordability: Corn cob is a relatively inexpensive abrasive media that can be used repeatedly, which results in tremendous long-term cost savings.
  • Eco-friendly: Corn cob is an all-natural material that is also biodegradable, which can help your company remain compliant with today’s increasing stringent environmental regulations.
  • Versatility: The multi-purpose nature of corn cob media means you can use it for several applications, which reduces the need to purchase different types of abrasive media types.
  • Safety: Corn cob blasting and polishing are nontoxic processes that do not produce dust or pollutants, which helps to create a less hazardous environment for your workforce.
  • Efficiency: Corn cob abrasive blasting is a more efficient dry finishing process. You can avoid the extra time-consuming steps involved with wet blasting.
