Abstract: A mobile steel grit dryer used to dry steel grit may be configured with a number of different functions and features to assist a contractor in performing steel or other structure maintenance when using steel grit in resurfacing the structure. The steel grit dryer may be configured with a heat process vacuum bypass so that an off-board vacuum, such as a vacuum on a grit recycling system, may be utilized as opposed to having an onboard vacuum. The dryer may include multiple modes so that an operator may use different modes for different environmental conditions. An exoframe may provide for better durability when being transported to different jobsites. A variety of automation and safety features may also be provided to simplify and improve safety for operators.
