In April 2025, a mid-sized pet food manufacturer based in Birmingham, UK, purchased one bone grinding machine (model: TZ-500) from our company to enhance their processing capacity for beef and lamb bones.
The machine was officially put into operation in May 2025 and has since significantly improved the factory’s output and product quality.

Customer background
This UK-based customer specializes in high-end, natural pet food production. Their product formulas rely heavily on finely ground bone meal as a calcium-rich ingredient.
Prior to this purchase, they were using a conventional crusher with low efficiency and inconsistent particle size, which impacted the consistency of their final products.
Customer requirements
During our consultation, the customer outlined the following key requirements:
- A stable processing capacity for both dry and wet animal bones.
- Final product particle size of at least 3 mm for dry bones.
- Full compliance with UK and EU food-grade hygiene standards.
Recommended configuration: TZ-500 bone grinding machine
We recommended the TZ-500 bone grinding machine, which meets all of the client’s expectations. Key specifications are as follows:

The machine features high-strength alloy blades and a robust internal screen system, making it ideal for long-term continuous use. It also supports quick disassembly for thorough cleaning, ensuring strict hygiene in food processing.
Real-world results
Since the bone grinding machine was installed, the customer has reported excellent results:
