Different Treatment Strategies Required in Stone Processing

Different treatment strategies required in stone processing will be discussed here. If you are curious, stay with us.

Chemical Post-treatment

Stumbling, slipping and falling have been at the top of the accident statistics for years and even exceed road traffic accidents. The cause is frequently insufficient anti-slip precautions for the flooring. Especially highly polished stone floors often do not meet the requirements, so that retrospective changes are necessary. Chemical post-treatment is one possibility of improving anti-slip properties. The anti-slip agent reacts with the minerals in the floor covering, releases these partly and roughens the stone. The microscopically small depressions improve the anti-slip properties.

Mechanical Operations

Mechanical operations on hard materials like granite, marble, concrete, etc. generate a lot of heat that can damage the tool and or the product. Often direct water cooling is applied to dissipate the heat and to flush the stone dust resulting from the mechanical operation away from the product.

Different Treatment Strategies Required in Stone Processing

To add more, the stone dust may partially dissolve, emulsify and or suspend in the wastewater, creating various problems. Depending on size and state, different treatment strategies are required to address these problems.

Grinding

For different stones there are different instructions before and during the process; and depending on the kind of stone, one must take special precautions in order not to damage the stone. One of these is filling of the pores and cracks of the stone with resin, cement, etc.

Resin Work

Often before the grinding phase, in order to increase the strength of stone and create a uniform-looking surface, a resin such as Epoxy, polyester or the new UV resin is used. The last resin, after being filled-in the stone, the stone must be put in a UV oven or before sunlight.

Leathering

In this process there is no limitation on the type of stone and all kinds of stones can be leathered. However, travertine and marble stones are most often used, during which process the weaker parts are broken off and a surface of ups and downs is created.

Hammering

From the ancient times, the stones used in road-building were hammered by a tool looking like a mason’s hammer having metal nail-line protrusions and a wooden handle. By this method, the degree of slipperiness of the stone surface and the danger of sliding on the stone was thus reduced.

Tumbling

The aim of antiquing is to make the stone look old and antique. This process is used mostly on travertine stones, and the process is done by either of a chemical or mechanical method.

Weathering

The weathering or wind-erosion process in done after mining. The mined stone is hit by a hand-held sledgehammer so some thick layers get broken off the stone’s surface.

Serration

To serrate the stone is done by sandblasting, shot-blasting and flaming methods.

Natural Stone Processing

Stone is a versatile material and the experience of watching finished stones which feature diverse colors and shapes, emerging out, are truly mesmerizing. A process of natural stones begins at the quarry, where a segment of solid rock is being found and blocks are segregated from it by minimizing the damage to stones Heavy devices are used for transporting stone blocks from quarry of processing yard, where they are sawed into slabs and tiles. Next sawing trims down the slabs into dimensional stonework.
