The Syrian glass manufacturing industry, although affected by regional challenges, continues to demand high-quality raw materials, especially talc powder. Talc is a critical component in the production of flat glass, container glass, and fiberglass, where it acts as a flux to lower melting temperatures, improve thermal shock resistance, and enhance the mechanical strength of the final product. For a production scale requiring 20 to 30 tons per hour (tph) of finished talc powder, selecting the right grinding equipment is essential to ensure consistent quality, energy efficiency, and operational reliability. Shanghai Zenith Machinery Co., Ltd., a leading manufacturer of ore grinding equipment in China, offers advanced solutions specifically designed for such demanding applications.
In glass making, talc (hydrous magnesium silicate) is primarily used as a source of magnesia (MgO) and silica (SiO₂). It replaces more expensive raw materials like dolomite and alumina, reduces the melting temperature by 100–150°C, and improves the workability of the molten glass. Talc also contributes to the clarity, brilliance, and resistance to thermal cycling of the final glass product. The ideal talc powder for glass applications typically has a fineness of 200–325 mesh (75–45 microns) with a controlled particle size distribution. A throughput of 20–30 tph is common for medium-to-large glass manufacturing lines, making it necessary to deploy robust grinding mills that can operate continuously with low maintenance.
Syria’s industrial sector faces unique conditions, including variable electricity supply, limited access to spare parts, and extreme climatic conditions. Therefore, grinding mills intended for the Syrian market must be durable, energy-efficient, and easy to maintain. Additionally, the local talc ore may have varying moisture content (up to 6%) and hardness. Zenith’s grinding mills are designed to handle these challenges, incorporating wear-resistant materials, intelligent control systems, and modular construction for quick replacement of parts. The company’s extensive experience in the Middle East and North Africa has led to tailored solutions that ensure maximum uptime even under harsh operating environments.
Based on the required capacity and final product fineness, Zenith offers two outstanding series that perfectly match the 20–30 tph requirement: the MTW Trapezium Grinding Mill (specifically the MTW215G model) and the LM Vertical Grinding Mill (specifically the LM190K model). Both machines have proven track records in talc grinding applications worldwide and comply with the highest environmental standards.
The MTW series is a patented trapezium mill known for its compact structure, long service life, and eco-friendly design. The MTW215G model offers a capacity range of 15–45 t/h, easily covering the 20–30 tph target. It accepts feed material up to 50 mm in size and produces final powder from 1.6 mm down to 0.038 mm (10–400 mesh). This wide flexibility allows glass manufacturers to adjust fineness according to their specific batch formulas. The mill features a bevel gear integral transmission, which reduces energy consumption by up to 30% compared to traditional Raymond mills. Its double-row anti-leakage sealing system ensures no powder leakage, protecting both the environment and operator health.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Fan Motor (kW) |
|---|---|---|---|---|---|
| MTW215G | <50 | 1.6–0.045 | 15–45 | 280 | 315 |
The LM series vertical mill integrates crushing, grinding, drying, and classifying in a single unit, offering a small footprint and simple operation. The LM190K model has a capacity of 23–68 t/h with an output fineness of 170–40 microns (approximately 80–400 mesh). Its grinding roller and table are made of high-chrome alloy, ensuring a long service life even when grinding moderately abrasive talc. The built-in classifier provides precise particle size control, which is critical for glass making where oversize particles can cause defects. The LM190K is also equipped with an automatic lubrication system and a PLC control panel, making it ideal for remote or partially automated plants in Syria.
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Max Feed Size (mm) | Main Motor (kW) |
|---|---|---|---|---|---|
| LM190K | 1900 | 23–68 | 170–40 | <45 | 500 |
Both the MTW and LM mills utilize the principle of layer grinding, where material is crushed between rolling elements and a grinding ring or table. In the MTW series, the trapezium-shaped rollers and ring ensure even distribution of material, improving grinding efficiency by 15–20%. The LM vertical mill, on the other hand, uses a conical roller profile that creates a high-pressure grinding zone, reducing energy consumption per ton of product. Each system includes a high-efficiency classifier that rejects coarse particles and returns them for regrinding, while fine powder is collected via a bag filter or cyclone. Additionally, both mills can be equipped with hot air drying systems to handle talc with moisture content up to 6% without pre-drying, a valuable feature for Syrian operations where raw material moisture may fluctuate.
Choosing Zenith’s MTW215G or LM190K for talc grinding offers several specific benefits for the Syrian market:
In a similar project for a glass manufacturer in the Middle East, Zenith supplied two MTW215G mills operating in parallel to produce 40 tph of 325-mesh talc powder. The customer reported a 25% reduction in energy costs and a 10% increase in glass production efficiency due to more consistent talc quality. Another Syrian client using an LM190K vertical mill for dolomite and talc grinding achieved 30% less wear on mill internals compared to a previously used ball mill, thanks to the vertical mill’s lower impact forces and superior grinding bed stability.
For glass manufacturing in Syria requiring a talc grinding capacity of 20–30 tph, Shanghai Zenith Machinery Co., Ltd. provides two outstanding solutions: the MTW215G Trapezium Grinding Mill and the LM190K Vertical Grinding Mill. Both offer exceptional reliability, energy efficiency, and product consistency, backed by Zenith’s decades of experience in the grinding equipment industry. Whether you prioritize a smaller footprint (LM) or the proven trapezium design with high flexibility (MTW), Zenith can customize the solution to your specific raw material and site conditions.
