Pre-Roll & Grinder Equipment

A pre roll machine replaces hand rolling with tray-based filling, so each cone gets an even fill and a consistent weight. Start with a Futurola Knockbox or Mini-RocketBox for smaller runs, then move to a RocketBox 2.0 or PRO with a commercial grinder as volume grows.

Types of Pre-Roll Equipment

Cone Filling Machines

The STM Mini-RocketBox PLUS+ packs 72 cones in 30 to 45 seconds with no pre-weighing. The RocketBox 2.0 fills 453 cones per cycle, and the RocketBox PRO runs five independent stations. Futurola Knockbox kits fill 100 or 300 cones per run, with devices for standard, slender and Fatboy cones.

Grinders and Shredders

For bench batches, the STM Mini-Revolution grinds about a pound every 1 to 2 minutes. The Revolution 2.0 handles 15 to 30 lb an hour, and the GreenBroz Model G is rated at 100 lb an hour with three screens. The High-Tech Shred Sifter screens out 99.5% of stems in the same pass.

Bulk Cones and Line Modules

RAW, Elements and Futurola cones come in boxes of 500 to 5,400, from 70 mm to 109 mm king size. STM's Cone Lander loads a 72-count tray in 2 to 3 seconds. The Atomic Closer folds a Dutch crown on 72 cones in 39.8 seconds.

How Growers Use Pre-Roll Equipment

Grind to an even particle size first, since it sets how evenly each cone fills. Mobius ships 2 and 3 mm screens for pre-roll work, and STM runs best on flower at 7 to 10% moisture. Load, fill, close, then check weights on the STM LaunchPad.

Frequently Asked Questions

How many pre-rolls can a pre roll machine make?

It depends on the size of the machine. The Mini-RocketBox PLUS+ packs 72 per 30 to 45 second cycle. The RocketBox 2.0 fills 453 in about three minutes, up to 20,000 a day. The RocketBox PRO turns out 360 to 715 per minute, over 3,000 an hour with a 2 to 3 person crew.

What is the best grinder for pre-rolls?

Match the grinder to your volume and keep the particle size even. The STM Mini-Revolution suits small batches at about a pound every 1 to 2 minutes. The GreenBroz Model G is rated at 100 lb an hour with three screens, and the Shred Sifter removes stems with a #8 mesh.

How do you fill pre-roll cones?

Load empty cones into a tray, pour in ground flower, then let the machine pack them. The Mini-RocketBox PLUS+ uses a nitrogen airbag and lift plate to pack from the bottom up, up to 1.2 g per cone. Close the tops with a crowning tool or the Atomic Closer, then weigh.
