Specifications
- This machine is used for leveling and polishing the surfaces of mosaics and stones.
- Belt sanding machines are available in models with 3 to 15 heads, in either geared or pneumatic types, with adjustable sanding levels for each head.
- The machine features a mosaic transfer system via a conveyor belt, which is automatically controlled, with the conveyor belt driven by a gearbox.
- The arrangement of the heads in this system is designed such that the initial heads are dedicated to rough and coarse surfaces and are equipped with diamond abrasives. Typically, 1 to 3 initial heads in each machine have diamond abrasives, while the remaining heads use sanding stones. As the stone or mosaic approaches the final heads, the abrasiveness decreases, so that in a belt sanding machine with multiple heads, the final heads usually perform only surface polishing.
- The initial heads equipped with diamond abrasives operate with a 15-horsepower electric motor, while the heads with sanding stones and without diamonds operate with a 10-horsepower electric motor.
- The machine requires 50 amps of electricity.
- For sanding the back of mosaics, a 2- or 3-head sanding unit can be used in this machine, with an automatic mosaic flipper placed between the units.
Sanding Stone
Mosaic sanding stone is a category of high-density construction flooring. This concrete product achieves its density through pressing or vibration (vibratory) methods. Mosaics come in various types and designs and are produced in different dimensions. The materials used in mosaics include cement, sand, fine and coarse aggregates, stone powder, water, and additive colors. Sanding stones are also used for restoring and renovating stones. Using sanding stones can address other issues, such as leveling uneven stone surfaces.
Mosaic Belt Sanding
Sanding the mosaic surface is part of the production process that occurs after molding and pressing, and it is the most critical stage in achieving the aesthetic and external appearance of the mosaic. Up to this stage, the produced mosaic has a hard and uneven surface, and the details of the design and embedded stones are not visible.
Additionally, mosaic belt sanding is performed when the stone is damaged by substances like acid or vinegar, leaving marks on the surface. This issue is resolved through stone sanding, resulting in a shiny stone.
Stone Sanding Machine
To achieve optimal results, various mosaic sanding methods are used with a stone sanding machine, which are briefly discussed below:
- Traditional Sanding: A common method in the past, where a rotating abrasive stone disc was used on the mosaic surface.
- Automatic Sanding: A mechanized version of the traditional method, where the mosaic surface is sanded by a large abrasive stone disc after being placed on the machine’s supports. Older automatic sanding machines consisted of two jaws and a moving abrasive stone disc, powered by an electric dynamo.
- Belt Sanding: Used in large factories. Belt sanding grinds, polishes, and finishes stones. In this machine, mosaics move via an automatic conveyor belt and are sanded by various stones. The degree of sanding, polishing, product dimensions, and surface roughness or smoothness can be adjusted and monitored.
Sanding Stone
This multi-head machine, available in geared and pneumatic types, allows for the adjustment and control of stone sanding levels based on customer requirements. This result is achieved by installing 3 to 15 heads along the mosaic sanding path. To enable each head to independently sand the stone or mosaic surface to a specific level of smoothness and polish, a system consisting of a pressure gauge and stone holder is installed on them. The arrangement of the heads along the sanding path varies based on their sanding capacity. Diamond-equipped heads, designed for rough and coarse surfaces, are placed at the beginning of the path, followed by heads with medium sanding, and at the end, the sanding process becomes polishing.
