Belt Grinders - DBB

Trade name:
Double Bench Beltit (DBB)

DBB

Generic Description:
Bench mounted abrasive belt grinder

Power:
Electric - inverter converts single to 3-phase

Applications:
The Double Bench Beltit has created revolutionary new methods of work in Turbine, Glassware, China Ceramic and Porcelain industries.

Method:
Unique belt grinder operating two arms, enabling grinding and polishing at the same work station, at the same time.

An abrasive belt on one arm grinds out imperfections and a felt belt on the other arm polishes to provide an excellent, consistent finish.

DBB

Benefits:
Each item of work is handled only once which saves time and effort.
Use to overcome all rectification problems occurring throughout production processes, by grinding out and polishing imperfections.

Increase production:
Much faster than old methods of polishing stones/wheels/mops. Polish 250 pieces per hour, compared to 100 pieces*.

Reduce labour costs:
Inexperienced operators can be fully productive in two weeks.

Safety:
Emergency stop button, very safe controls with shrouded start button and RCD circuit breaker.

Low vibration and noise levels:
The low vibration levels (less than 2.5 m/s²) provide for greater operator safety. Greatly reduced workshop noise.

Operator comfort:
Safe, quiet and clean. Gentle cushion contact between item and belt.

Low energy:
Very low current consumption - less than 4 amps.

Very Reliable:
Inverter converts single to 3-phase. Stepless speed control (1,000 to 7,500 rpm).

Fan cooled inverter and motor are both fitted with overload and overheat protection.

As with all Beltits, the Double Bench Beltit is exceedingly reliable. Many End users work their machines on a continuous basis, working 3 shifts, 24 hours per day.

Proven Success:
Most UK and Irish ceramic and glassware manufacturers have changed their production ware rectification to make extensive use of the Double Bench Beltit. One end user has over 90 machines in constant use.

"The introduction of the Beltit machines into the finished polishing area revolutionised the method of rectifying faults at a very small capital outlay. Beltit finishing machines are now well established in all our grinding and polishing departments" (report extract courtesy of Spode Ltd, 1998).

China ceramic and porcelain:
Rectify surface imperfections - kiln dirt, decal fault, gold flake removal. Grind underglaze faults prior to glazing. Most on- or in-glaze faults can be totally removed.

Glassware:
Remove blisters and seam faults. Quickly repairs and achieves best quality. Excellent finishes on crystal glass.

Turbine rectification:
A range of arm attachments to enable grinding and polishing of difficult to access areas. “Single sided arm” enables abrasive belts to work right up against an edge.

Safe use of water:

  • Water feed versions provide operator with controlled flow of water to belts to give superb finish
  • RCD protection allows the use of slurry (compound and water)
  • Water feed option gives extra protection from isolating transformer
