BMH spare parts maintain the capacity, availability, and lifetime of your equipment.

BMH supplies spare parts for the full range of equipment in solid biomass handling and waste refining lines, including receiving, shredding, crushing, separating, conveying, and storage equipment. We deliver parts for every BMH-built machine throughout its lifetime and can also supply spare parts for equipment from other manufacturers across European markets.

Yes, BMH supplies spare parts for equipment from other manufacturers, primarily in European markets. For parts outside the original BMH design, our specialists start with an on-site visit and measurements to ensure the parts fit correctly and perform reliably in your line. For BMH-built equipment, spare parts are available globally throughout the lifetime of the machine.

The typical shredder spare parts that wear out fastest are knives, counter knives, and screen mesh. In TYRANNOSAURUS® shredders, these are typically replaced a few times per year, though exact intervals depend on your material stream, operating hours, and shredder configuration.

Well-performing wear parts directly affect process quality: sharp, correctly fitted knives produce a cleaner cut and more consistent particle size. In TYRANNOSAURUS® shredders the opposite edges of each knife can be utilized by turning them 180°, effectively doubling knife service life.

The fastest-wearing parts across a TYRANNOSAURUS® production line are knives, counter knives, chains, wear rails, and the stars of the star screen. These components carry the highest mechanical load in daily operation, and their condition has a direct effect on your line’s throughput and output quality. Well-maintained wear parts keep throughput steady and end product quality consistent. Replacement intervals vary depending on your material stream, operating hours, and line configuration. For an assessment of your line’s current condition, our specialists offer shutdown planning inspections.

Original BMH spare parts protect your line’s performance, extend wear intervals, and reduce total operating cost. BMH spare parts are designed to fit the equipment exactly, made from hardened materials developed over decades, and manufactured through audited suppliers under our ISO-based quality system. Non-OEM spare parts may cost less upfront, but they typically wear faster, may not fit correctly, and can accelerate wear on surrounding components, costing more over the lifetime of your equipment.

Spare parts delivery time depends on the specific part, current stock, and urgency of the situation.

For planned replacements, we work with you to schedule orders in advance, often through shutdown planning inspections that identify needed shredder spare parts and other wear parts well before your maintenance window. For standard orders, our network of trusted suppliers helps us keep delivery times as short as possible. For urgent needs, we prioritise the fastest possible solution. Certain critical parts, such as shredder knives, are kept in limited stock at BMH for unexpected breakdowns.
