animal bedding machine

Start with your target output. Different materials yield different throughput on the same machine. Wood gives you the highest output; straw and grass drop by 30–50%; paper sits somewhere in between. For a 520 model (ring die diameter 520mm), expect roughly 1.5–3 T/H for wood, 1–2 T/H for straw, and 1.5–2.5 T/H for paper. Also consider your feedstock availability – if you can only run 8 hours a day, oversizing the mill wastes capital. If you plan to run 24/7, invest in a robust gearbox and automatic lubrication.

Our rule of thumb: size the mill 20% above your target – it gives you breathing room for material variations and die wear. Tell us your material and desired daily output – we’ll match the model.

It varies by material – and getting this wrong is the 1 reason pellets fall apart.

For wood, aim for 13–18% moisture. Too dry? The pellets won’t bind. Too wet? They’ll expand and crack. Straw and grass need 12–15% – but grass is trickier because it absorbs moisture unevenly. Paper can tolerate slightly higher, up to 15%, but anything above that and you’ll see die blockage. For fermented bedding (probiotic‑laced mixes), keep it around 14–16% – the sticky nature demands tighter control. Peat? Low compression ratio (1:4–1:6) means moisture matters less, but we still recommend 12–14%.
Pro tip: invest in a moisture meter. It pays for itself in saved downtime.

Absolutely – if you have a steady waste paper stream. Cardboard, newspapers, office paper – these are cheap (or free) feedstocks. Our paper pellet mills turn them into lightweight, highly absorbent pellets with minimal dust. Output ranges from 0.3 to 5 T/H, so even small operations can be profitable.

The catch? Paper needs more careful moisture control – too wet and it clogs; too dry and it won’t bind. We use stainless steel feeders and polished dies to reduce friction. Also, paper pellets are lighter than wood, so shipping cost per ton is higher – factor that into your business model. But if you’re near a paper waste source? The margins are solid.

Yes, the same mill can produce both – but the pellet specs differ.

For small pets (hamsters, rabbits, rats), you want small‑diameter pellets (2–4mm), ultra‑low dust, and high softness – paper and wood pellets work well here. Livestock bedding (cattle, horses, pigs) demands larger, denser pellets (6–10mm) that hold up under heavy weight and moisture – wood and straw are the go‑to choices. The machine itself doesn’t care – we just swap the die and adjust the compression ratio. But here’s the catch: if you’re producing for both markets, you’ll need to clean the system between runs (especially if switching from paper to straw) to avoid cross‑contamination. Also, livestock pellets are produced at higher volumes – a 520 model gives you 1.5–3 T/H for wood, while small‑pet runs are often much smaller.

It depends on your priorities. Wood pellets (sawdust, shavings) are the gold standard – highly absorbent, low dust, and they break down slowly. Horses and cattle prefer them. But they cost more. Straw pellets are cheaper and more available if you’re near grain farms – they’re softer underfoot and compost better. But they’re less absorbent and break apart faster, so you’ll use more.

Our recommendation? If you’re running a commercial feedlot, wood is worth the premium – it reduces bedding changes and labor. If you’re a smaller farm or have straw as a by‑product, straw pellets make economic sense. We can tune the compression ratio: 1:6–1:10 for wood (dense and durable), 1:10–1:15 for straw (softer but still stable). Both work – just match your material to your budget and animal type.

Three specialty materials, three different approaches.

Peat – high moisture retention, popular in large livestock barns (especially Europe). We use a low compression ratio (1:4–1:6) to avoid over‑compacting.
Fermented bedding – mixed with probiotics that break down waste, reducing cleaning frequency. The material is sticky, so we add a variable‑speed feeder and run the mill cooler to prevent paste‑up.
Tofu/soy fiber – primarily used as flushable cat litter, but also works for small pets. It needs a stainless steel die and a scraper blade to prevent the mold from sticking together. Each requires tailored die specs, motor RPM, and feeder design.
