The WEIWEI 800 and 1000 are built to remove the stick. Material goes onto a belted infeed table and is carried into the cutting chamber, where a hold-down roll presses it onto the rotor instead of relying on gravity. Both rotors turn at 9.8 r/min — slow, but with enough torque that a fork of green branches is drawn in rather than batted back. That is the whole point of the "forced feed" layout: the machine decides the feed rate, not the person standing next to it.
Both models run the same 22 kW main motor on a standard three-phase supply, with no tractor and no PTO shaft. That matters for a nursery, a municipal yard or a landscaping contractor working from a shed with a 63 A breaker rather than a farm tractor. The 800 measures 3,460 × 1,500 × 1,750 mm and is rated 1–5 t/h; the 1000 measures 3,500 × 1,400 × 1,700 mm and is rated 5–6 t/h. The difference between them is chamber length and belt speed, not motor size — which is why a buyer who only compares kilowatts will pick the wrong one.
Discharge height and direction are the other half of the job. Material that comes out onto a concrete slab has to be picked up twice; material that comes out at trailer height does not. The discharge is set to throw into a trailer, a bunker or a windrow for composting, and the rotor screen decides whether the output is a coarse mulch for weed suppression or a finer material for composting.
Typical duty is prunings, palm fronds, hedge cuttings, bark and light construction offcuts — the material a municipality or estate collects every week and has to pay to dispose of. Running the same machine on dry pallet wood is possible but wasteful; the forced-feed layout pays for itself on wet, bulky, irregular green waste, which is exactly what landfill sites are trying to stop accepting.
Zhengzhou Weiwei Machinery has manufactured agricultural and wood machinery in Henan since 1980 and holds CE and ISO 9001 certification. Tell us the material, the moisture and how high your trailer sits, and we will tell you whether the 800 or the 1000 is the honest answer — and what the discharge chute should look like.
