Breton microwaves resin-treating plant for granite slabs

Good morning,
I wish to inform you that, besides a polishing line for granite slabs “Levibreton KG 4000 PLUS”, we installed the first Breton resin-treating line using microwaves at CERESER MARMI, a company that has been working marble and granite for quite a while.

ADVANTAGES OF THE LINE
.
- IMPROVED RESTORATION OF THE SLAB, ensuring excellent results.
.
- POLISHING IS ENHANCED: resin betters polishing.
.
- REDUCTION OF WAIT TIMES: products are available for immediate delivery.

A loader with vacuum cups lifts the material from the A-frame supporting the “humid slabs” (installed on a rotating platform). 

The work cycle of this automatic loader makes it possible to process slabs arranged in the "diamond-match" pattern as well. 

Slabs are placed on a support platform resting on the pick-up station.

After being rotated 90°, the slab is conveyed to a station which is used as a bypass unit, meaning that catalyzed slabs can be unloaded and humid slabs (in transit to the conveyor) can be loaded at the same time.

The platform with the slab is placed in the drying area of the kiln.

Once the time required for drying is over, both the platform and the slab are removed and placed on the conveyor that transfers them to the resin-treating station. If slabs are to be reinforced, the operator applies automatically a fibreglass net on the material surface using the suitable device. 

The application of the specific resin for microwaves on the slabs, either to beautify them or to glue the net, is executed automatically under the spray-gun of the resin-treating unit.

Slabs pass through the catalysis kiln one by one, according to the cycle time of the line. 

MICROWAVE OVEN TECHNICAL DATA SHEET 
 - oven type: microwaves and hot air 
 - total power: 250 kW 
 - microwave unit: 9+9 magnetrons (microwave generators) 
 - air unit: 8 fans for magnetron cooling 
 - air recirculation unit: 4 fans for air recirculation + 1 fan for steam extraction 
 - dimensions: 9.74 x 3.16 (h) x 2.15 m 
 - surface: 30 sq.m 
 - cycle time: 4 min./slab 
 - production rate: 15 slabs/hour 
 - shielding: microwave-specific shielding 
 - insulation: 50 mm rockwool panels

After a possible manual retouching with resin, the unit transfers the supporting platforms to the lower conveyors.

The platforms with the resin-treated slabs are then conveyed to the cooling area of the catalysis station.

After a few minutes, cooled slabs are unloaded and conveyed to the bypass station where they are lifted so that the humid slabs can pass below.

The finished slabs are rotated 90° so that the automatic offloader can lift and unload them on the A-frame supporting the “resin-treated slabs” (installed on a rotating platform).

Well, that’s all for today.

I hope the resin-treating process of this Breton line is clear enough.

TOPWIRE 2 AXES - 2-axes shaping machine for marble and granite

TOPWIRE 2 AXES

2-AXES SHAPING MACHINE TOPWIRE 2 AXES
Machine for shaping and cutting marble and granite small blocks, provided with a motorized block-holding platform actuated by a brushless motor.

Through the interpolation of the vertical cutting axis and the horizontal axis for the trolley movement, the shaping machine generates profiles such as columns, cornices, components for funerary art and interior decoration.

Breton TOPWIRE 2 AXES is provided with special, swivelling wire driving pulleys installed next to the points where the wire gets into, and comes out from, the block, to follow the cutting direction. Its outfit is complemented by special drives for the axes positioning and a powerful, user-friendly CAD/CAM programming software to be installed on the PC of the customer.

BESTWIRE 4WD - Rail-mounted single-wire machine

BESTWIRE 4WD



RAIL-MOUNTED SINGLE-WIRE MACHINE

Machine for squaring blocks and cutting slabs and thick slabs, performing a programmed and automatic cutting of several blocks placed on the floor.
The machine features an arc-welded steel structure which is heat treated to ensure the required stiffness of the system and a top cutting precision. It is provided with a large diameter driving pulley to rotate the wires, actuated by belts and an inverter controlled asynchronous motor that optimizes the wire peripheral speed in accordance with the material to be sawn.
A driven pulley with the same diameter is constantly kept under tension by a pneumatic cylinder thus giving the wire the ideal tension. The assembly is complemented by two independent, upper driven pulleys and two wire driving pulleys installed next to the points where the wire gets into, and comes out from, the block.
The machine is mounted on motorized wheels sliding on floor-fixed rails. Extremely simple to be operated, the machine is provided with a programming software with user-friendly interface for the execution of multiple cuts.
