Problems solved by technology

However, said method means that a lot of impregnating agent is consumed and likewise means that it turns into a stage where it is difficult to recycle and reuse
Much would be gained by changing to a preparation that has the potential to increase the strength of the stone product without the need for impregnation which can become expensive in the long run

Embodiment Construction

[0014] The present invention relates to a method for producing a slab-shaped stone product 1 from natural stone 2 , comprising removing, in thinner slabs 1 , the stresses occurring in said stone 2 . The method implies that the stone 2 is dried so that a stress relief of the stone 2 is obtained. According to the invention, the stones 2 are dried therein from the inside by using a microwave dryer 3 in which the stones 2 remain for a certain period of time so as to obtain their stress relief.

[0015] By housing the stone 2 inside the microwave oven 3 for a certain time, the entire stone 2 is efficiently dried from the inside 4 .

[0016] After drying in said microwave oven 3, the stones 2 are heated to at least 100° C. for a certain time. Preferably, the stone 2 is further heated and dried by using infrared radiation 5 of the stone 2 .

[0017] After said heating of the stone 2, said stone 2 is cooled to room temperature of about 18 to 25°C. Acquiring this cooling varies quic...

Abstract

The invention concerns a proceeding for the production of slab-shaped stone products (1) from blocks (2) of natural stone. According to the invention, occurring stresses in the stone block (2) are removed, before saw-cutting of said stone block (2) into thinner slabs (1), by drying the stone block (2) internally by utilising a micro wave dryer (3) and thereby attaining stress relief of the same. The invention also concerns a plant for carrying out a proceeding according to the invention.

Description

technical field [0001] The invention relates to a method for producing pan-shaped stone products from natural stone blocks, and to a device for carrying out said method. Background technique [0002] It is previously known through SE470185B to increase strength in conjunction with the production of disc shaped stone products to allow sawing of thin discs from stone. Likewise, suitable stone products as well as devices are therefore expected to be protected thereby. However, said method implies the consumption of a lot of impregnating agent and likewise means its transition to a stage where it is difficult to recover and reuse. Much would be gained if instead it was possible to increase the strength of the stone product without impregnating a formulation which would become expensive in the long run. Contents of the invention [0003] The main object of the present invention is therefore mainly to solve (among others) said problems in a technically efficient manner and als...
