Stop trying to force a frozen block of beef into a standard meat mincer.
Last month, I walked into a pet food factory in Semarang (Indonesia). The floor manager was screaming because his 30kW grinder shaft had just snapped in half. Why? Because they were trying to grind -18°C frozen chicken frames directly.
If you skip the “Shredding” stage, you are destroying your downstream equipment. You need a Primary Breaker.
Whether you are making rich broth for Pho in Vietnam, Bakso paste in Indonesia, or exporting bone meal, you need to reduce the size before you grind. Here is the engineering reality of the Dual-Shaft Shredder and the Impact Bone Crusher.
Why are you still letting your workers manually chop heavy cow femurs with cleavers, risking injury and wasting 40% of the marrow? If you run a slaughterhouse or a central kitchen in Southeast Asia, you already know the brutal reality of prepping bones for Pho (Vietnamese noodle soup) or Kuah Bakso (Indonesian meatball broth). When the factory floor hits 36°C with 90% humidity, standard grinders overheat, their cheap blades chip, and your broth loses its rich, milky consistency. You need a real industrial animal bone crusher that doesn’t just crack bones, but shears them down to a micro-level. This isn’t about looking high-tech. It’s about maximum marrow extraction and protecting your profit margins.
Definition: A high-shear, heavy-duty mechanical reduction system designed to fracture and pulverize dense animal byproducts—specifically bovine and porcine femurs—down to a 0.178mm micro-paste for optimal nutrient extraction in commercial broth and pet food production.
| Model | Inlet Size (mm) | Power of Motor (kW) | Output (kg/h) | Machine Weight (kg) | Product Size (mm) | Industry Reality Check (The “Hidden Rule”) |
|---|---|---|---|---|---|---|
| 280 Type | 220 × 230 | 5.5 | 150-200 | 600 | 1200×850×1100 | Good for poultry and fish frames. Don’t feed it heavy cattle skulls. |
| 400 Type | 300 × 230 | 7.5 | 300-400 | 750 | 1200×950×1100 | The sweet spot for pork bones and commercial pet food processing. |
| 600 Type | 500 × 230 | 11 | 600-800 | 1300 | 1300×1150×1100 | Requires stable 380V 3-phase power. Check your local grid before buying. |
(Note: Production finished material size across all models is strictly engineered to a 0.178mm fine paste).
Most suppliers will try to sell you on motor RPM alone. At the end of the day, if you don’t solve the kinetic impact absorption on the main shaft, all that speed just destroys your bearings. We use custom-treated alloy blades designed for high-stress cyclic loading. The Advantage: It shears raw, dense cow bones down to a 0.178mm emulsion without thermal degradation. We keep the cutting chamber temperature rise strictly under 3°C during the crushing phase——this in the 2026 industry standards, is the absolute baseline. The Benefit (Your Profit): Equipment reps love throwing around fake numbers like “efficiency increased by 30%.” Ignore them. Look at the reality. When processing raw beef femurs for Pho broth base, actual extraction yield on our 600 Type goes from 65% (using standard 10mm cracked bones) to 88% using our 0.178mm paste. It doesn’t sound like a massive revolution. But run that across a double shift, and you are saving 120 kg of raw bone stock every single day, while doubling the collagen concentration in your soup.
Southeast Asian processing floors are wet, hot, and highly corrosive. High ambient heat, constant moisture, and aggressive chloride-based cleaning foams will eat cheap carbon steel alive. The Advantage: We built this 1300 kg beast with a fully enclosed, safe-operation hopper and heavy-duty motor shrouds to dissipate heat effectively in tropical climates. The Benefit (Your Profit): Less catastrophic downtime. Here is a dirty little secret: when operators wash down a bone crushing machine, if they blast the main shaft labyrinth seals at a 45-degree angle with a high-pressure water gun, the grease washes out and the bearings seize within a week. We engineered a secondary purge gap and angled the water-shedding plates. You won’t be replacing bearings just because your sanitation crew got aggressive with the hose.
Q: Will this handle deep-frozen cow femurs directly? No. Don’t let any salesman lie to you. For the 0.178mm ultra-fine output, you must thaw the bones to at least -2°C, or use a coarse pre-breaker first. Feeding deep-frozen solid bovine femurs directly into a fine grinder will snap the alloy blades.
Q: How hard is it to source replacement parts in Thailand or Indonesia? We don’t use proprietary, locked-down electrical panels. The 5.5 kW to 11 kW motors run on standard SEA 380V 50Hz 3-phase power. As for the blades, we ship two extra sets with the machine. When they dull, you can have them re-sharpened at any local industrial machine shop using our provided CNC angle specs.
Q: Is it difficult to clean the crushing chamber? The front protective hopper swings open on heavy-duty hinges. You can access the entire cutting chamber for sanitation. Just remember the golden rule: clean the 0.178mm screen immediately after your shift ends before the bone marrow fat solidifies, and never point the high-pressure nozzle directly into the motor ventilation cowlings.
