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.
Claims9
A method of processing steel grit being used to treat a structure, said method comprising:
- receiving a vacuum pressure airflow at a heat process bypass path of a steel grit dryer;
- applying the vacuum pressure airflow from the heat process bypass path to a vacuum hose extending from the steel grit dryer used to vacuum the steel grit into the steel grit dryer after the steel grit has been blasted against the structure and prior to being reused by a steel grit blast machine;
- transitioning the steel grit from the vacuum pressure airflow prior to drying the steel grit;
- drying the steel grit vacuumed into the steel grit dryer to produce dried steel grit;
- bypassing the vacuum pressure airflow past heated air in which the steel grit is being dried;
- and
- re-entraining the dried steel grit back into the vacuum pressure airflow to cause the dried steel grit to be vacuumed from the steel grit dryer.
