[Two-Pass Grinding]

In most cases, a two-pass grinding process is more economical than a one-pass grinding process. When finished product sizing is critical for things like mulch and compost a two-pass regrind is optimal. Pregrinding material on the first pass for feedstock reduction with large-holed hex grates, and regrinding material for sizing with small-holed round grates offers faster production, lower fuel consumption, and a more consistent end product.
