Breton Drying of Slabs,Catalysis Unit Before Resin Treating

THE DRYING OF SLABS BEFORE RESIN-TREATING

Different techniques for the slab drying were tested (static hot-air drying with air dehumidification, hot-air passage, irradiation passage, static radio-frequency, etc.) and their advantages and disadvantages in terms of output and operating costs were crosschecked.

Breton suggests the most suitable drying techniques according to the type of resin used, the material to be resin-treated (marble or granite) and the required production capacity.As for the static hot-air drying with air dehumidification, Breton developed special multi-decker vertical kilns ensuring a “homogeneous” drying of all the slabs housed in the kiln.

Depending on the requirements, slabs move along the automated resin-treating line while they are held up by special, rigid steel supports.Breton suggests the most suitable catalysis techniques according to the type of resin used, the material to be resin-treated (marble or granite) and the production capacity.As to the static catalysis of the resin-treated slabs, Breton developed special vertical multi-decker kilns with hot-air circulation which ensure an ideal catalysis of the slabs housed in the kiln.

The catalysis of marble slabs treated with polyester resin may also be performed in line, while they return to the loading point and move on a conveyor placed under the processing line along its longitudinal axis, with no need of kilns.
