GR764 Pulsar Aluminum Crank Grinder – 4pc – 2.5″

The crank mechanism on the Pulsar GR764 replaces the standard lid-twist grinding motion with a hand crank that rotates the grinding plate in one continuous direction. The crank is attached to the top of the grinder and is turned with one hand while the grinder body is held stationary with the other. Each rotation of the crank drives the diamond-shaped teeth across the herb loaded in the chamber, shredding it progressively with each turn. The single-direction continuous crank motion requires less grip strength than the back-and-forth twisting of a traditional grinder and reduces the repetitive wrist motion that can cause discomfort during heavy grinding sessions.

The clear acrylic top lid of the Pulsar GR764 allows users to watch the herb being ground inside the chamber as they crank the mechanism. In a standard grinder with an opaque lid, the only way to check grind consistency is to stop and open the grinder. The clear top eliminates this interruption by providing a continuous view of the grinding surface. Users can stop cranking when the herb has reached their preferred consistency, whether that is a coarser chop for bowls or a finer grind for rolling. The clear lid also lets users see when the chamber is running low and needs to be reloaded without opening the grinder and risking spills.

Yes. The GR764 is a 4-piece grinder with a sifting screen and pollen chamber at the base. Ground herb falls from the grinding chamber through drop-down holes into the storage compartment above the screen. The finest particles, including trichomes and pollen, continue through the mesh screen into the pollen chamber at the base. Over multiple sessions, a supply of concentrated kief accumulates in the bottom chamber. The included scraper tool is used to collect kief from the chamber walls and surface when enough has built up to be harvested.

The crank mechanism on the Pulsar GR764 is a mechanical addition to the standard grinder body and is subject to the same wear considerations as any moving part. User reviews indicate the crank functions well for regular daily use, though heavy or aggressive cranking can stress the mechanism over time more than a standard lid-twist grinder would experience. Using the crank with smooth, consistent rotation rather than rapid or forced cranking extends the life of the mechanism. Pulsar includes a 1-year limited warranty that covers manufacturing defects in the product. If the crank develops issues, the grinder body itself continues to function as a standard grinder with the lid attached, as the teeth and threading are not affected by the crank.

The Pulsar GR764 Aluminum Crank Grinder is available in multiple color options. Common available finishes include black, blue, green, gunmetal, and rasta, though specific availability at Haze Smoke Shop may vary based on current inventory. Each color option uses the same anodized aluminum body, clear acrylic top, crank mechanism, and internal components. Color selection does not affect grinding performance. Contact Haze Smoke Shop to confirm which specific color options are currently in stock.

For routine cleaning, use a small brush to clear herb debris from the diamond-shaped teeth and the holes in the grinding plate after each session. Separate the four pieces by unscrewing the lower sections and use a brush and the included scraper to collect ground herb and kief residue. For a deeper clean, soak the aluminum components in isopropyl alcohol for 20 to 30 minutes, brush away dissolved residue, rinse with warm water, and dry completely before reassembling. The clear acrylic top lid should be wiped clean with a damp cloth rather than soaked in alcohol, as prolonged alcohol exposure can cloud or damage acrylic. Do not submerge the crank mechanism in liquid; wipe the crank pivot point with a dry cloth.
