Overview
Techtongda's grinder is a stainless steel commercial mill rated for 30-60 kg/h of dry material, aimed at grinding grains, beans and spices rather than home-kitchen quantities.
A 2200W motor drives it at 1500 rpm, with fineness adjustable from 50 to 150 mesh and magnetic devices at the outlet to catch stray metal wear particles. Techtongda specifies dry grain only, ruling out wet or oily ingredients.
- Production rate 30-60 kg/h (66-130 lb/h)
- 2200W copper wire motor at 1500 rpm
- Adjustable fineness, 50-150 mesh
- Overload protection with simple on/off controls
Who it's for
Aimed at small shops, processors or high-volume home users grinding dry grains, seeds or nuts. One buyer's experience suggests it is not the right tool for fine herb or leaf grinding.
What buyers say
From Amazon customer reviews.
The single review describes returning the unit after finding metal scrapings in the ground material at the tightest setting, with the noise going away only when loosened, which then gave a coarser grind than needed. The same reviewer called the motor and overall build well made, and suggested the mill is better suited to seeds and nuts than to a fine herb powder.
Strengths and trade-offs
Drawn from this product's published specifications.
- 2200W motor with overload protection
- Adjustable fineness from 50 to 150 mesh
- Stainless steel food-contact parts
- Magnetic filters catch metal particles
- One reviewer found metal scraping at the tightest setting
- Not rated for wet or oily ingredients
- May not reach a fine powder for soft materials like herbs
Performance notes
The mesh setting trades fineness against smooth operation. According to the one detailed review on file, tightening the mill enough for a fine grind produced metal-on-metal contact and metal scrapings in the output, while loosening it to stop that noise left the grind coarser than the reviewer wanted for herbs.
