Cremulators & processors

What a cremulator does

Cremation does not reduce the skeleton to fine powder. What remains are calcified bone fragments together with metal from coffin fittings and medical implants. After cooling, operators remove the metal, often with magnets and by hand, and then place the fragments in a cremulator or processor that reduces them to a uniform granule size suitable for an urn or scattering.

The quality of this step matters to families. Consistent, clean ash without visible fragments or foreign material reflects the care of the crematorium. Processors also affect staff health because they handle fine dust, so enclosure and extraction are important.

Types of processors

• Rotating drum processors with steel balls or beaters, valued for consistency and low maintenance.
• Blade or cutter processors that work quickly and suit high-throughput sites.
• Integrated cooling and processing stations that combine cooling, metal separation and processing in one enclosure.
• Pet-specific processors sized for small volumes and individual identification.

Each design has trade-offs in speed, noise, dust and how well it handles residual metal. Ask manufacturers how the machine tolerates small metal items that slip through separation, because damage to blades or drums is a common maintenance cost.

Metal separation and recycling

Orthopaedic implants such as hip and knee replacements contain valuable metals. Many crematoria, with the consent of families or under local policy, send recovered metals to specialised recycling programmes, sometimes donating proceeds to charity. A good processing station makes separation efficient and safe, with magnetic separators and sieves that keep metals away from the processor.

Dust control and operator safety

Bone ash is fine and can become airborne. Look for fully enclosed processors with local exhaust ventilation and HEPA filtration, plus ergonomic loading heights. In many countries occupational health rules set exposure limits for respirable dust, so the processor should be part of your workplace risk assessment.

Identification and chain of custody

Every crematorium must ensure that the remains returned are those of the person cremated. Processors should allow the identification disc or tag to stay with the remains throughout, and some stations integrate barcode or RFID scanning with the cremator's data system. Ask how each supplier supports traceability.

Buying advice

Processors are often bought separately from the cremator, and many sites use a different brand. Consider throughput (minutes per case), noise level, footprint, power supply, ease of cleaning between cases, availability of wear parts and warranty. Ask for a demonstration with real cremated remains, and check whether the processor can handle pet and human remains if you plan to serve both markets.

Because processors are relatively affordable compared to the cremator itself, it is tempting to treat them as an afterthought. In practice they are used for every single case, so reliability and a clean, dignified result are worth paying for. Include processors in the same tender as your cremator, or in a separate lot, so suppliers price them transparently.

Budget also for spares: a set of blades or drum liners, filters and seals kept on site can prevent days of disruption. Ask suppliers how quickly parts ship to your country and whether local distributors hold stock.

Processors in pet crematoria

Pet crematoria process many small individual remains each day, so speed of cleaning between cases and reliable identification are critical. Compact processors with removable bowls simplify cleaning and help ensure each family receives only their own pet's ashes. If you serve both humans and pets, consider separate processors to maintain clear separation and reassure families.
