The engineered stone industry in Indonesia is experiencing significant growth, driven by robust construction and interior design sectors. A critical component in the production of high-quality engineered stone, such as quartz surfaces and solid surfaces, is finely ground gypsum powder. This powder acts as a crucial filler and binder, influencing the final product’s strength, consistency, and aesthetic appeal. Achieving the precise particle size distribution and purity required for engineered stone necessitates advanced, reliable grinding technology. For production lines targeting a capacity of 10 to 20 tons per hour (TPH), selecting the right grinding mill is paramount to ensuring efficiency, product quality, and long-term operational profitability.
In engineered stone production, gypsum (calcium sulfate dihydrate) is processed into a fine, consistent powder. This powder must meet stringent specifications regarding fineness (typically ranging from 170 mesh to 325 mesh or finer), moisture content, and chemical purity. The grinding process directly impacts the reactivity of the gypsum with resins and other additives, the smoothness of the slurry, and the final surface finish of the stone slab. An inconsistent or coarse grind can lead to weak points, poor texture, and increased resin consumption, thereby raising costs and compromising quality.

For Indonesian producers aiming for a 10-20 TPH output of gypsum powder, several factors must guide the equipment selection:
Shanghai Zenith Machinery Co., Ltd., a leading manufacturer of ore and industrial powder grinding equipment, offers ideal solutions for this specific application. With extensive expertise in ultra-fine powder processing, Zenith’s mills are engineered for high performance, reliability, and eco-friendly operation. For a 10-20 TPH gypsum grinding line for engineered stone, two of our products stand out as particularly suitable: the LM Vertical Grinding Mill and the MTW Trapezium Grinding Mill.
The LM Vertical Grinding Mill is a premier choice for modern mineral processing plants. Its standout feature is the integration of five functions—crushing, grinding, powder selection, drying, and conveying—into a single, cohesive unit. This integration makes it exceptionally space-efficient and simplifies the entire process flow. For gypsum grinding, its built-in hot air system can effectively dry the material during grinding, which is a significant advantage in humid climates like Indonesia’s. The grinding roller and plate are designed for long service life and easy replacement, ensuring stable, continuous output.
For a 10-20 TPH requirement, the LM130K model is perfectly matched. Its technical parameters are detailed below:
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Max Feed Size (mm) | Main Motor (kW) |
|---|---|---|---|---|---|
| LM130K | 1300 | 10-28 | 170-40 (approx. 80-400 mesh) | <38 | 200 |
As shown, the LM130K’s capacity range comfortably encompasses the 10-20 TPH target, with room for future expansion. Its ability to produce powder as fine as 40μm (approx. 400 mesh) meets and exceeds the fineness requirements for high-grade engineered stone fillers.

Another excellent option from Zenith’s portfolio is the MTW Trapezium Grinding Mill. This mill incorporates multiple national patents and is renowned for its curved surface duct, internal lubricating system, and efficient cyclone powder collector. It offers superior grinding efficiency, lower noise levels, and is designed with environmental protection in mind. Its structure is robust yet allows for easy access to key components for maintenance.
For the specified capacity, the MTW138Z model is highly recommended. It is engineered to deliver stable, high-volume output of fine powder with excellent particle shape.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) |
|---|---|---|---|---|
| MTW138Z | <35 | 1.6-0.045 (adjustable) | 6-17 | 90 |
The MTW138Z operates at the higher end of the 10-20 TPH spectrum. Its advanced grinding curve and efficient transmission system ensure lower energy consumption per ton of product, making it a cost-effective solution for medium-to-large scale engineered stone producers in Indonesia.
