Good morning everyone.
Last week I visited Campolonghi, an Italian company from Montignoso (MS), world leader in quality stone production.
Here you can get an idea of its projects!
They have just installed a Levibreton KG 4600 high-production line for polishing granite slabs. Here below you can see it in action.
The Levibreton KG granite polisher is a project of utmost industrial success, both for Breton as a producer and for customers who have bought it, with more than 1,300 machines produced to date.
LEVIBRETON
KG 4600 - THE REAL INNOVATION IN GRANITE POLISHING
- Polishing
width 2200 mm
- 19 8-brick polishing heads, 510 mm in
diameter: higher production thanks to
the increased number of operating bricks (152 bricks).
- 19 8-brick polishing heads, 510 mm in
diameter: improved surface levelling thanks
to the larger head diameter.
- 19 8-brick polishing heads, 510 mm in
diameter: reduced installed power:
reduced wattage (285kw vs 315kw needed for 21 heads).
- Super rigid
structure with 12 support legs.
- Improved dynamics
in beam acceleration ramps and greater belt speed control: with brushless motors.
- Coordinated
belt and beam speed: thanks to the usage
of brushless motors, when the beam inverts travel direction, the belt speed can
be increased so as to homogenize the permanence of the abrasives on the slab.
- Rigid,
lightweight and dynamic beam/spindle system:
the weight being equal, both the design and cross section of the beam
have been changed according to the increase of rigidity. lightweight spindles
and motors with aluminium casing.
- ultra
fast beam: max. speed up to 70 m/min.
- Slab profile
reader with photoelectric barrier: with
a 1x1cm resolution, it eliminates any possible reading problem on polished and
resin-treated surfaces.
- Ergonomics
and each single parameter under control:
positioned in proximity of each single spindle: selector switch for
raising/lowering the head, head pressure regulator, head pressure gauge and
head amp indicator.
- PC-automated
dynamic control of the working pressure for all heads offering improved polishing.
- Colour touch-screen
monitor and fully-developed user-friendly machining software, capable of
storing (and recalling) different working programs for various types of
material, with automatic control of the beam and belt speed, beam speed
interpolated with the belt speed, working pressure of the single heads,
interpolation between the pressure of the single heads and the beam exact
position.
- Transfer of
energy to the network: when the beam
slows down, the excess energy is fed back to the network thanks to "energy
recovery drives".
