FAQs

How many pre-rolls can I produce per day with the RollCraft MRB? +

The RollCraft MRB can produce up to 10,000 pre-rolls per day at speeds reaching 1,250 per hour. Actual output depends on your workflow, material characteristics, and operator efficiency. The machine packs 72 or 143 pre-rolls in approximately 90 seconds per cycle. Using an efficient grinder such as the Mini-Revolution Commercial Grinder can help ensure your material is ready for consistent packing.

How does the MRB compare to the Mini RocketBox Plus? +

The RollCraft MRB provides a cost-effective solution for craft producers seeking automated filling. While the Mini RocketBox Plus+ offers higher packing force (98 ft-lbs), faster pack times (30 seconds to 1 minute), and industrial-grade heavy-duty steel frame construction, the MRB delivers excellent value with its 44 ft-lbs force, compact portable design, and the same 10,000 pre-rolls per day capacity and 1,250/hour speed—ideal for small-to-mid operations.

What tray sizes work with the RollCraft MRB? +

The RollCraft MRB is compatible with both 72-joint trays and 143-joint trays, giving you flexibility to scale production or accommodate different batch sizes. This dual compatibility ensures the machine can grow with your operation as demand increases, and supports all common cone sizes including standard cones and slim cones.

What does the low/high power setting control? +

The low/high power settings adjust the packing force to accommodate different material densities and moisture levels, ensuring consistent results across various flower types. This allows you to dial in the optimal fill density for your specific flower or blend without over-compacting or under-filling, delivering repeatable weights batch after batch.

Is the RollCraft MRB portable? +

Yes, the RollCraft MRB features a compact and portable light-duty chassis that can be easily relocated as needed. This portability is ideal for craft producers who may need to move equipment between workstations or don't have dedicated production space. The compact footprint also makes it easy to integrate into small existing facilities without requiring dedicated floor space or facility modifications.

How much faster is the MRB than traditional knockbox methods? +

The RollCraft MRB operates 3-4x faster than traditional knockbox methods while delivering superior fill consistency and reduced operator fatigue. This speed improvement, combined with more reliable weights, significantly reduces your cost per unit and labor requirements. The efficiency gains are most noticeable during sustained production runs where manual methods suffer from operator fatigue and declining consistency.

Is the MRB suitable for my operation if I'm currently hand-filling? +

Yes, the RollCraft MRB is specifically designed for craft producers ready to transition from hand-filling to automated production. It offers an accessible entry point into automation with simple setup and operation, and for a complete workflow, it can be paired with a compatible pre-roll closer machine.
