A sawmill loses money on residue not because the wood is bad but because the pile leaves the gate as one unsorted tonnage that no board line, MDF refiner, pellet mill or presswood pallet line can buy against its own spec. This page follows a graded-output decision on a Pulvz wood pulverizer machine: replaceable 780 to 1480 mm screens as the grading element, F-800 to F-1500 on 45 kW, 55 kW, 75 kW and 110 kW drives covering a nominal 1 to 8 t/h, infeed openings from 680 x 380 mm to 1350 x 450 mm, belt conveyor feeding, manganese steel hammer plates and one-piece liner, and a hydraulic open cover for hammer and screen access. Limits are stated plainly: nominal tonnage moves with species, moisture, infeed evenness and screen condition, the 5 mm figure is a screen-set target band rather than a guarantee, and magnetic separation is a project-confirmed stage.

A sawmill’s mixed pile of bark, slabs, edgings, trimmings, sawdust and shavings is refused at the gate on two measurable things: size distribution from dust to slab, and contamination from dirt, grit, stones and cut wire. This page follows that pile through a Pulvz wood pulverizer machine: F-800 to F-1500 on 45 kW, 55 kW, 75 kW and 110 kW drives covering a nominal 1 to 8 t/h, infeed openings from 680 x 380 mm to 1350 x 450 mm, replaceable 780 to 1480 mm high-hardness screens holding the discharge at a 5 mm target and finer, manganese steel hammer plates and a one-piece liner, belt conveyor feeding for an unsorted pile, and a hydraulic open cover for hammer and screen access. The boundaries are stated plainly: nominal tonnage moves with species, moisture, infeed evenness and screen condition, the 5 mm figure is a screen-set target band rather than a guarantee, and magnetic separation is a project-confirmed stage, not a standard item on every unit.

A sawmill that sells sawn timber also sells, or burns, a large share of every log as slabs, edgings, trimmings, sawdust and shavings. This page follows that residue through a PULVZ wood pulverizer machine: F-800 to F-1500 at 45 kW, 75 kW and 110 kW, nominal 1 to 8 t/h, replaceable 780 to 1480 mm screens holding output at 5 mm and finer, manganese steel hammer plates and one-piece liner, belt conveyor feeding for uneven mixed residue, and a hydraulic open cover for hammer and screen access. Boundaries are stated plainly: nominal tonnage varies with species, moisture, infeed evenness and screen condition, and metal separation is an upstream stage, not a machine feature.

A recycling yard that takes whole pallets, used formwork and block offcuts cannot feed a narrow-mouth machine. This page follows one wood pallet crusher decision from the pile to the settings that hold a long shift on a PULVZ wood pulverizer machine: an F-1500 infeed of 1350 x 450 mm taking whole units without pre-cutting, 5 to 8 t/h inside a 1 to 8 t/h range with 45 kW, 75 kW and 110 kW drives, belt conveyor feeding for continuous infeed, one-piece manganese steel liner and dynamic balancing technology, a hydraulic open cover for hammer and screen access, and a replaceable 780 to 1480 mm screen holding output at 5 mm and finer for the presswood pallet line.
