Libya’s construction and infrastructure development sector relies heavily on a robust and efficient cement production industry. A key component in modern cement manufacturing is the use of supplementary cementitious materials (SCMs) or alternative raw materials to enhance performance and reduce costs. Basalt, a volcanic rock abundant in many regions, has emerged as a valuable material for this purpose. When finely ground, typically to a fineness of 150 mesh (approximately 100 microns), basalt powder can improve the mechanical properties and durability of cement. This article explores the technical requirements for grinding basalt to 150 mesh for cement production in Libya and presents optimal milling solutions.
Basalt is known for its hardness and abrasiveness, posing significant challenges for grinding equipment. The goal of achieving a consistent 150-mesh product for cement blending demands a mill that offers not only precise particle size control but also high throughput, energy efficiency, and exceptional wear resistance. Factors such as the harsh Libyan climate, potential for dust generation, and the need for reliable, low-maintenance operation further complicate equipment selection. The ideal solution must integrate crushing, grinding, drying (if the material is moist), classifying, and conveying in a system designed for industrial-scale production.
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. We are specialized in the research, development, and production of industrial powder grinding equipment and other related devices. With decades of experience, Zenith provides tailored solutions for processing hard and abrasive materials like basalt, ensuring high efficiency and long-term operational stability for projects worldwide, including in North Africa.
For the specific application of grinding basalt to 150 mesh for cement production, Zenith’s LM Vertical Grinding Mill and MTW Trapezium Grinding Mill stand out as the most suitable and efficient choices.
The LM Vertical Grinding Mill is particularly recommended for its all-in-one design. It integrates five functions—crushing, grinding, powder selection, drying, and material conveying—into a single machine. This is highly advantageous for processing basalt, as it simplifies the production line, reduces footprint, and minimizes dust emission. Its grinding roller and plate are made from high-wear-resistant materials, perfectly suited for abrasive basalt. The built-in high-efficiency classifier ensures precise control over the final product fineness, reliably achieving the 150-mesh target.
For a Libyan cement plant aiming for medium to large-scale production of basalt powder, the LM190K Vertical Grinding Mill is an ideal model. Its technical parameters are as follows:
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Max Feed Size (mm) | Main Motor (kW) |
|---|---|---|---|---|---|
| LM190K | 1900 | 23-68 | 170-40 (~90-325 mesh) | <45 | 500 |
This model’s capacity range comfortably covers typical demands, and its output fineness range easily encompasses the 150-mesh (~100 micron) requirement with high efficiency and stability.
Another excellent option is the MTW Trapezium Grinding Mill. Known for its multiple patented technologies, it features a curved surface duct, internal lubricating system, and arc air channel design. These features contribute to lower energy consumption, higher productivity, and more environmentally friendly operation. The MTW series is also highly adaptable and offers excellent wear protection, making it durable for basalt processing.
For this application, the MTW175G model offers a great balance of capacity and fineness control:
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) |
|---|---|---|---|---|
| MTW175G | <40 | 1.6-0.045 (~10-325 mesh) | 9.5-25 | 160 |
Its ability to produce powder in the range of 0.1mm (150 mesh) is well within its operational parameters, providing a reliable and cost-effective grinding solution.
Choosing Zenith’s grinding mills brings tangible benefits. The high grinding efficiency translates to lower power consumption per ton of product, a critical factor given operational costs. The robust construction reduces maintenance frequency and downtime, which is crucial for remote locations. Furthermore, the sealed and negative pressure operation of these mills effectively controls dust, ensuring a cleaner plant environment and compliance with environmental considerations. By producing a consistent 150-mesh basalt powder, cement manufacturers can improve their product quality, potentially reduce clinker factor, and enhance the sustainability profile of their final cement.
The successful integration of basalt into cement production in Libya hinges on deploying the right grinding technology. Achieving the optimal 150-mesh fineness requires mills that are precise, rugged, and efficient. Shanghai Zenith’s LM Vertical Grinding Mill and MTW Trapezium Grinding Mill are engineered to meet these exact demands. With their advanced design, proven performance on abrasive materials, and comprehensive after-sales support, they represent an ideal investment for Libyan cement producers looking to optimize their raw material processing, improve product quality, and strengthen their competitive edge in the market.
