Saudi Arabia’s rapidly expanding plastics and construction industries are driving a significant demand for high-quality fillers. Cement clinker, after being finely ground, has emerged as a cost-effective and technically viable filler for plastic products such as PVC pipes, cable insulation, and injection-molded parts. With the country’s Vision 2030 initiatives boosting local manufacturing and infrastructure development, the need for reliable and efficient grinding mills capable of producing 20-30 tons per hour (TPH) of fine cement clinker powder has never been greater. This article explores the technical requirements for such an application and presents optimal grinding solutions from Shanghai Zenith Machinery Co., Ltd., a leading Chinese manufacturer of ore grinding equipment specialized in ultra-fine powder processing.
Cement clinker is a hard, abrasive material with a Mohs hardness of around 6-7. To be used as a plastic filler, it must be ground to a fineness typically between 80-400 mesh (180-38 microns), with a narrow particle size distribution for consistent performance. The grinding process must also minimize iron contamination, as metallic impurities can discolor plastic products. Additionally, the mill must operate efficiently in Saudi Arabia’s hot and arid climate, where material moisture content is generally low but ambient temperatures can exceed 50°C. A capacity of 20-30 TPH requires a mill that balances high throughput with low energy consumption, durability, and ease of maintenance.
Shanghai Zenith Machinery Co., Ltd. has established itself as an excellent manufacturer of ore grinding equipment in China, with remarkable achievements in the ultra-fine powder grinding field. The company specializes in research, development, and production of industrial powder grinding mills, offering a wide portfolio including MTW Trapezium Grinding Mill, MTM Medium-Speed Grinding Mill, LM Vertical Grinding Mill, LUM Ultrafine Vertical Mill, Raymond Mill, Ball Mill, and Hammer Mill. For the specific requirement of grinding cement clinker to plastic filler grade at 20-30 TPH in Saudi Arabia, two standout solutions are the MTW215G Trapezium Grinding Mill and the LM130K Vertical Grinding Mill. Both are proven in the field for similar applications and deliver the desired capacity and fineness while offering low operating costs.
The MTW series is a patented trapezium mill known for its compact structure, long service life, and eco-friendly design. The MTW215G model is particularly suited for cement clinker grinding with a maximum feed size of 50 mm and a capacity range of 15-45 TPH, which comfortably covers the 20-30 TPH target. Its multi-roller pendulum design and advanced classifier ensure a final product fineness adjustable between 1.6-0.045 mm (approx. 10-325 mesh), ideal for plastic filler applications. The mill’s internal lubrication system and automatic grease injection reduce maintenance downtime—a crucial advantage in remote Saudi projects.
| Parameter | Value |
|---|---|
| Maximum Feed Size | ≤50 mm |
| Final Product Fineness | 1.6 – 0.045 mm |
| Capacity | 15 – 45 t/h |
| Main Motor Power | 280 kW |
| Fan Motor Power | 315 kW |
| Ring Roll Number | 6 pcs |
The LM Vertical Grinding Mill integrates crushing, grinding, powder selection, drying, and material conveying into a single unit, offering a small footprint and high efficiency. The LM130K model has a plate diameter of 1300 mm, a capacity of 10-28 TPH (within the 20-30 TPH window when operated at optimum conditions), and an output fineness of 170-40 μm (80-400 mesh). Its built-in classifier ensures precise particle size control, crucial for consistent plastic filler quality. The vertical mill design is especially advantageous in hot climates because of its high drying capability (using hot gas), though clinker typically needs minimal drying. The LM130K’s wear parts are made of high-chrome alloy, extending service life when grinding abrasive clinker.
| Parameter | Value |
|---|---|
| Plate Diameter | 1300 mm |
| Capacity | 10 – 28 t/h |
| Output Fineness | 170 – 40 μm |
| Maximum Feed Size | ≤38 mm |
| Main Motor Power | 200 kW |
Both the MTW215G and LM130K can effectively achieve 20-30 TPH of cement clinker grinding for plastic filler. The MTW215G offers higher maximum capacity (up to 45 TPH) and a slightly coarser top product range (down to 0.045 mm), making it a robust choice if future scalability or coarser filler grades are needed. The LM130K, on the other hand, provides finer product control (down to 40 μm) with lower energy consumption per ton due to its vertical grinding principle. For plastic filler applications requiring high fineness (e.g., 200-400 mesh), the LM130K may be more economical and space-efficient. Both mills are designed for easy maintenance, with Zenith’s global service network ensuring prompt support in the Kingdom.
Selecting a Zenith grinding mill for cement clinker filler production brings several key advantages to Saudi investors: Energy efficiency – advanced grinding technologies reduce power consumption by up to 30% compared to traditional ball mills; Low maintenance – automatic lubrication and wear-part designs minimize downtime; Environmental compliance – the mills are equipped with efficient dust collectors and operate with low noise, meeting Saudi environmental standards; Local adaptability – Zenith mills have been successfully installed in other Middle Eastern countries with similar climates. Furthermore, with the Saudi government encouraging local manufacturing of plastic products, investing in a reliable grinding mill ensures a steady supply of high-quality filler, reducing import dependence.
