"If you're grinding the wrong product, it will affect [machine] life. You will also lose production," says John Foote, Morbark. "If you know you're going to be [grinding] something with a lot of contamination, select 'protection' options or consider a low-speed, high-torque grinder rather than a high-speed grinder."
Selecting the right teeth and screens is also important, says Jason Morey, Bandit Industries. Screens range from 1 to 8 in. in diameter, so matching them to the task is relatively easy. However, Morey notes that Bandit offers about 20 teeth options, ranging from splitter and shingle teeth to pallet teeth. You can also use a combination of a couple different designs for optimum grinding ability.
As such, it pays to consult with your grinder equipment supplier to determine which teeth type(s) can give you top performance based on the material you plan to process.
