Granite grinding mill for Turkey decorative stone

Granite Grinding Mill for Turkey Decorative Stone

Turkey is one of the world’s leading producers and exporters of natural stone. The country’s rich granite reserves, combined with a strong decorative stone industry, have created a large demand for efficient and reliable granite grinding equipment. Decorative stone products – including terrazzo tiles, engineered stone slabs, mosaic pieces, and architectural panels – often require finely ground granite powder as an aggregate or filler. The quality of this powder directly affects the strength, appearance, and durability of the final product. Therefore, choosing the right grinding mill is essential for Turkish manufacturers and investors.

Shanghai Zenith Machinery Co., Ltd. is an excellent manufacturer of ore grinding equipment in China and has made great achievements in the field of ultra-fine powder grinding. The company specializes in the research, development, and production of industrial powder grinding equipment and related devices. Its main products include the MTW Trapezium Grinding Mill, Ball Mill, MTM Medium-Speed Grinding Mill, Raymond Mill, LM Vertical Grinding Mill, LUM Ultrafine Vertical Mill, XZM Ultrafine Grinding Mill, and Hammer Mill. Among these, the MTW Trapezium Grinding Mill and LUM Ultrafine Vertical Mill provide ideal solutions for granite decorative stone powder production in Turkey.

Characteristics of granite and its decorative applications

Granite is a hard, crystalline igneous rock with high compressive strength and excellent wear resistance. It is widely used in building decoration, kitchen countertops, stair treads, floor tiles, and outdoor paving. During the processing of granite slabs and blocks, significant quantities of waste powder, dust, and small chips are generated. Instead of being discarded, these by-products can be collected and processed into high-value decorative stone powders. These powders are used as fillers in terrazzo, artificial stone, paints, plastics, rubber, and sealants.

For decorative stone applications, particle size distribution and consistency are very important. Coarse powder around 80 to 120 mesh can be used in terrazzo and aggregate boards, while finer powder from 200 to 400 mesh is suitable for artificial stone and coatings. Ultra-fine powder with D97 below 30 microns is increasingly demanded in premium engineered stone and polymer-based decorative products. A grinding mill must be able to produce a stable and adjustable fineness to meet these diverse specifications.

Why granite grinding requires a specially designed mill

Granite has a hardness of about 6 to 7 on the Mohs scale and contains high levels of silica and feldspar. This makes it highly abrasive to grinding parts. A standard mill may suffer from excessive wear, high energy consumption, and unstable output if it is not designed for hard materials. The MTW Trapezium Grinding Mill manufactured by Zenith is a patented grinding machine with a compact structure, long service life, and eco-friendly operation. Its trapezium-shaped grinding rollers and ring reduce material slip, increase grinding efficiency, and help extend the life of wearing parts. The air-pressurized sealing structure prevents leakage of dust and keeps the working environment clean.

The MTW mill accepts a maximum feed size up to 50 mm, depending on the model, and can grind materials to a final fineness from 1.6 mm down to 0.045 mm. This range covers the majority of decorative stone powder applications. For medium-to-large Turkish producers, the MTW175G is a highly recommended model. It accepts feed sizes smaller than 40 mm, produces final product from 1.6 to 0.045 mm, and has a capacity of 9.5 to 25 tons per hour. The main motor power is 160 kW, and the fan motor power is 200 kW. This machine offers an excellent balance between output, energy consumption, and product quality.

The need for ultra-fine granite powder and the LUM mill

As the Turkish decorative stone market becomes more sophisticated, many manufacturers are moving toward value-added products that require ultra-fine powder. For example, engineered and agglomerated stone panels often use granite powder with a D97 of 5 to 30 microns. Producing this fineness reliably and economically demands a mill with superior classification ability and stable grinding force. Zenith’s LUM Ultrafine Vertical Mill is designed for this exact duty. The LUM mill integrates grinding, drying, classifying, and transportation into one unit. It occupies a small footprint and can produce powder with a high content of end-fines. With an intelligent control system, operators can easily monitor and adjust the process, reducing maintenance burden and improving operation safety.

The LUM1632 model is particularly suitable for Turkish decorative stone processing lines. Its main machine power ranges from 280 to 315 kW, its capacity is 2.0 to 13.5 tons per hour, and its product size distribution is D97 5 to 30 microns. When producing ultra-fine powder from pre-crushed granite, this mill provides a high-quality output that can be used in premium artificial stone, high-end paints, and specialized polymer composites. For companies that want both medium-fineness bulk powder and ultra-fine powder, a combination of MTW and LUM mills can be designed as a complete production system.

Complete granite grinding process for decorative stone

In a typical Zenith granite grinding line, the process starts with a hopper and vibrating feeder, which deliver raw granite to a jaw crusher. The crusher reduces large blocks to smaller particles smaller than 30 to 40 mm. The crushed granite is then conveyed by a bucket elevator to a storage bunker. From the bunker, a vibrating feeder and a batching device send the material into the grinding mill at a controlled rate. Inside the mill, the granite is ground between the roller and ring or between the roller and millstone. The ground powder is carried upward by the airflow to a classifier, where particles that are too coarse are returned for further grinding. Fine powder is collected by a cyclone collector and a bag filter. The clean air is discharged by an induced draft fan, meeting environmental requirements.

Zenith offers complete turnkey solutions for this process, including crushers, feeders, conveyors, mills, classifiers, collectors, and control systems. The company has extensive experience in the design and commissioning of powder grinding plants for marble, granite, limestone, talc, feldspar, and many other minerals. This experience ensures that the equipment selected for a Turkish decorative stone project is reliable, efficient, and precisely matched to the raw material and final product.
