Indonesia, as one of the fastest-growing economies in Southeast Asia, has witnessed an increasing demand for construction materials, especially aggregates and sand produced from natural stone such as granite. Granite aggregates are widely used in infrastructure projects, road bases, and concrete production. Efficient grinding and crushing of granite into fine and uniform aggregates not only enhance the quality of construction materials but also improve project efficiency.
In this context, selecting a suitable granite grinding mill is crucial. This article discusses the process and technology behind a 20–30 tons per hour (TPH) granite grinding system and highlights how Shanghai Zenith Machinery Co., Ltd. provides advanced, durable, and high-performance grinding equipment suitable for Indonesia’s demanding construction and aggregate market.
Granite is a hard igneous rock composed mainly of quartz, feldspar, and mica. Its durability, compressive strength, and resistance to weathering make it a preferred material in the construction industry. However, due to its hardness, granite requires high-efficiency grinding and crushing equipment capable of processing the material into uniform aggregates suitable for concrete and road construction.
A 20–30 TPH granite grinding plant offers a perfect balance between capacity and cost-effectiveness for medium-sized projects, such as city infrastructure development and regional road construction projects in Indonesia.
Shanghai Zenith Machinery Co., Ltd. is a leading manufacturer of ore grinding equipment in China, renowned for its innovation and reliability in ultra-fine powder and mineral grinding systems. With decades of experience in industrial grinding machines, Zenith has developed a range of professional mills suitable for different materials, fineness requirements, and production capacities.
The company specializes in R&D and production of industrial powder milling equipment and related devices, offering solutions for mining, metallurgical, chemical, and construction industries. For the Indonesian granite aggregate market, Zenith provides customized solutions covering the entire grinding process—from coarse crushing to fine powder classification.
To achieve a stable output of 20–30 tons per hour, the grinding system should combine high efficiency, stability, and reduced downtime. Two of Zenith’s products stand out as optimal solutions for this capacity range:
Both models are ideal choices for medium-scale aggregate plants in Indonesia due to their high adaptability to local materials, ease of operation, and compliance with environmental standards.
The MTW series by Zenith integrates advanced European grinding technology with long service life and environmental friendliness. It is suitable for grinding hard materials such as granite into fine particles with controlled fineness. The built-in powder separator ensures consistent output quality.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Fan Motor (kW) |
|---|---|---|---|---|---|
| MTW138Z | <35 | 1.6–0.045 | 6–17 | 90 | 110 |
| MTW175G | <40 | 1.6–0.045 | 9.5–25 | 160 | 200 |
The MTW175G model, with a capacity range of 9.5–25 t/h, can be used for lower-end 20 TPH configurations, while an MTW215G or additional mill line can achieve the upper 30 TPH target depending on material hardness and feed fineness.
For customers looking for an integrated system combining crushing, grinding, drying, and classification, Zenith’s LM Vertical Grinding Mill is a highly efficient choice. It minimizes space requirements and offers stable performance. The LM Vertical Mill is suitable for large-scale continuous operation, making it ideal for granite-based construction aggregate production.
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Max Feed Size (mm) | Main Motor (kW) |
|---|---|---|---|---|---|
| LM130K | 1300 | 10–28 | 170–40 | <38 | 200 |
| LM190K | 1900 | 23–68 | 170–40 | <45 | 500 |
The LM130K Vertical Mill can easily handle 20–30 TPH granite grinding with excellent fineness control, offering energy savings of up to 30% compared to conventional ball mills. Its vertical design ensures low vibration and efficient material drying, which is beneficial in humid Indonesian conditions.
When designing a 20–30 TPH granite grinding plant, engineers must consider the following parameters:
Modern grinding systems are not just about capacity—they also must align with environmental and sustainability goals. Zenith’s mills are designed with dust-proof housings, low-noise fans, and efficient dedusting systems. These features ensure compliance with Indonesia’s environmental standards while reducing maintenance costs and energy consumption.
For Indonesia’s growing construction sector, the 20–30 TPH granite grinding line represents a key production scale that balances output, cost, and efficiency. With Shanghai Zenith Machinery’s advanced MTW Trapezium and LM Vertical Grinding Mills, contractors and producers can achieve superior quality aggregates while maintaining operational stability and compliance with environmental regulations.
By integrating Zenith’s advanced grinding technology into your production line, Indonesian aggregate producers can achieve not only higher productivity but also more sustainable and intelligent manufacturing.
