Stage 2 Crusher: High-Capacity Industrial Bone Processing
The Stage 2 Crusher is a versatile, heavy-duty processing solution engineered to meet the rigorous demands of the pet food industry, agricultural operations, and laboratories.
Designed for high-volume environments, its primary function is the effortless pulverization of pre-broken animal bones into precise particle sizes ranging from 3mm to 15mm.
Step 1: Vital System Integration (Input)
Important: This unit is specifically engineered to refine material that has already been reduced in size.
For optimal efficiency, this unit is best paired with our Stage 1 Pre-Breaker. The output from Stage 1 (shown in the photo) is the ideal feed size to maximize the speed and longevity of the Stage 2 Crusher.

INPUT MATERIAL: Pre-crushed bones from Stage 1
? Operational Insight: Why is 2-4 Inches the Ideal Input Size?
Based on the "Stage 1 Output" images and the machine's design as a secondary processor, the recommended input bone size is approximately 2 to 4 inches (50mm – 100mm). Here is why this size is critical for performance:
- 1. The "Pre-Breaker" Standard:
This "fist-sized" chunk is exactly what your Stage 1 Pre-Crusher produces. It is small enough to easily fall into the crushing mechanism but large enough for the rollers to grab effectively. - 2. Machine Longevity:
The Stage 2 Crusher is a "finisher." It is designed to refine material, not break whole carcasses. Feeding it pre-broken chunks (2-4 inches) ensures the 440C blades face consistent wear rather than the shock impact of large, whole bones. - 3. Throughput Speed:
This specific size allows for a continuous flow. If bones are too large (e.g., whole leg bones), they may bounce on top of the rollers before catching, which slows down your 4500 kg/hr production rate.
Step 2: Final Product Results (Output)
The Stage 2 Crusher transforms the rough input into a consistent, high-quality mince ideal for pet food and fertilizer production.

Premium Construction & Hardened Components
Built for endurance and sanitation, the Stage 2 Crusher is constructed entirely from high-grade stainless steel to strictly adhere to food-grade standards. The internal crushing mechanism is engineered for maximum longevity, featuring:
- 440C Material Roller Blades: Hardened for superior wear resistance and extended edge retention.
- Stainless Steel Roller Shafts: Ensuring high strength and corrosion resistance at the machine's core.
The unit also features easy-to-clean technology that provides convenient access to these internal workings, ensuring a bacteria-free sanitization process and minimizing downtime.
Operational Versatility
While capable of crushing various bone types, the Stage 2 Crusher is optimized for processing fresh bones.
It is designed for seamless integration into existing production lines, equipped to discharge directly into a 200L Euro-type buggy or connect to a conveyor system for continuous workflow.
