Primary size reduction
Prepare bone for the next process—not a finished powder
The SGJ series uses claw-type crushing and optimized blade holders to apply shear and impact across irregular animal bones. The official output range is 5–80 mm, so this equipment should be treated as a primary or intermediate crusher. Fine bone meal or paste normally requires a defined downstream milling, emulsifying or separation stage.
Selection starts with bone species, fresh or dry condition, maximum incoming size, moisture, temperature and required downstream particle distribution. Capacity varies from 100–200 kg/h on SGJ-300 to 3,000–6,000 kg/h on SGJ-1050, but the correct model also depends on bridging risk, feed presentation and the largest piece that can safely enter its chamber.

Process sequence
Control feed before chasing throughput
Meter
Present bone at a controlled rate by hand or conveyor without overfilling or bridging the soundproof hopper.
Crush
Alloy-steel claws shear and impact the material; blade setting influences the resulting particle size.
Verify
Screen samples, record oversize and fines, monitor motor load, temperature rise and accepted kilograms per hour.
Crushing architecture
Adjustable, resharpenable alloy-steel blades
- Optimized claw-type blade holder distributes force and supports shear and impact resistance.
- Front-mounted blades increase cutting angle for efficient, more uniform reduction.
- Specially heat-treated alloy-steel blades are designed for durability.
- Retractable, adjustable blade mounting allows resharpening after wear.
- Stainless feed hopper includes soundproofing to reduce operating noise.
- Motor overload protection and a power-interlocked feed section support operator protection.
- Optional conveyor loading and discharge can reduce manual handling.
Particle-size adjustment method and screen configuration are not detailed on the exact page. Confirm the supplied rotor, blade gap, screens if applicable and changeover method for every required product.

External dimensions are withheld pending confirmation. The official source table contains obvious missing-zero or transcription errors in several rows, including entries such as 100 × 700 × 1090 and 1450 × 110 × 150 mm. Request a signed model-specific general arrangement rather than designing the room around those records.

SGJ bone crushing and discharge
What to inspect in the footage and trial
Watch the feed rate, hopper behavior, discharge flow and apparent particle spread. Note whether long or flat pieces bridge, whether output accumulates under the machine and how operators access the collection bin.
Video confirms machine architecture but does not prove capacity or a 5–80 mm distribution for every bone. A witnessed trial must use representative species, moisture and incoming dimensions, followed by sieve analysis.
Exact official machine range
Match chamber size to the largest incoming piece
Larger nominal capacity does not automatically solve uncontrolled feed. If bones exceed the safe hopper or chamber envelope, define upstream sawing or breaking. A metering conveyor should be interlocked to crusher load so it stops before overload or a dangerous jam develops.
For downstream broth or extraction, particle surface area and fines affect heat transfer, filtration and yield. For pet food or bone meal, oversize can overload the next mill while excessive fines increase dust. Specify a particle distribution, not only a maximum size.
Choose the right process
Bone crusher, saw or separator?
SGJ bone crusher
Reduces bones into smaller particles for extraction, milling, broth, pet-food or ingredient processes.
Bone saw
Creates saleable bone-in portions or defined cuts while preserving recognizable product geometry.
Meat-bone separator
Mechanically separates soft tissue from hard material; it is selected by yield and residual-calcium criteria.
Safety, hygiene and maintenance
Control stored energy before opening the chamber
Feed protection
Verify reach distances, hopper interlock and conveyor stopping so hands and tools cannot enter the rotor zone.
Jam recovery
Lock out power, prove zero motion and use an approved removal method; never reverse or probe an energized chamber.
Blade service
Define inspection, sharpening, balance, fastener torque and replacement criteria for every blade set.
Sanitation
Demonstrate access to hopper, chamber, blade holders and discharge without creating unsafe manual handling.
Bone fragments can be sharp and heavy, while dry material can create dust. Assess PPE, dust collection, noise, lifting aids and collection-bin ergonomics. Confirm stainless grade, ingress protection, cleaning chemicals, drainage and food-contact documentation in the quotation.
Factory acceptance test
Measure capacity and the complete particle distribution
Define the FAT lot by species, fresh or dry condition, moisture, temperature and minimum/maximum dimensions. Record gross input, accepted screened output, oversize, fines, losses, motor current, temperature rise, noise, vibration, bridging and interventions. Run long enough to expose blade heating and accumulation.
Use agreed sieves to quantify particle distribution at each required setting. Demonstrate overload response, feed interlock, emergency stop, restart prevention, safe jam recovery, blade access and full cleaning. For conveyor integration, test upstream stop logic and downstream bin-full or transfer faults.
Buyer questions
SGJ Industrial Bone Crusher FAQ
What bones can the SGJ series process?
The official page lists fresh and dry cattle, pig, sheep and fish bones. Maximum geometry and condition still require model-specific trials.
Does the machine make bone powder?
The published output is adjustable from 5 to 80 mm. Fine powder generally requires downstream milling; confirm the full process for the target specification.
Why are overall dimensions not shown?
The source table contains multiple obvious transcription errors. This page preserves reliable chamber, capacity and power values and requires a signed general arrangement for dimensions.
Is there an exact operating video?
Yes. The official product page exposes video ID ylv3lLxOgUA, embedded here after the process and specification sections.
