How to Choose the Right Floor Grinding Machine for Your Project

1. Select working width based on project area

• 250mm single-disc floor grinder: Working width 250mm, lightweight & flexible. Ideal for <300㎡ projects, edge grinding, stair grinding, partial floor repair, old tile glue removal and small epoxy floor pretreatment. It is the best entry-level machine for startup contractors.
• 300–450mm planetary grinder: For medium warehouse, supermarket floor polishing over 500㎡, high grinding flatness for large-area curing floor.
• Ride-on big grinder: Over 3000㎡ industrial factory ground only.

2. Power & Voltage Matching

• 110V/220V single-phase electric: Standard for indoor residential & small commercial, mainstream for 250mm compact grinders, easy to plug into regular household power socket.
• 380V three-phase: High torque for heavy concrete removal, mostly for wide-body industrial grinders.
• Gasoline power: Outdoor open construction without power supply.

3. Confirm your grinding purpose

• Remove paint, epoxy, glue: Pick grinder compatible with PCD grinding discs.
• Concrete rough grinding & laitance removing: Match metal bond diamond pads.
• Terrazzo/marble fine polishing: Need resin polishing pad supported machine.All our 250mm floor grinders support full set of above three abrasives to realize multi-scene use.

4. Dust control configuration

Modern construction requires dust-free grinding. Prioritize grinders with standard vacuum outlet to link industrial HEPA vacuum cleaner, reduce onsite dust and improve working safety.
