Algeria, as a rapidly developing North African nation, has witnessed a continuous surge in infrastructure and construction projects. From highways and bridges to residential and commercial buildings, the demand for high-quality construction aggregate is ever-increasing. Limestone, being one of the most abundant and cost-effective natural resources in Algeria, serves as the primary raw material for producing crushed stone, sand, and fillers. To transform raw limestone into usable construction aggregate, efficient grinding and milling processes are essential. This is especially true when the desired output is fine powder or manufactured sand with specific particle size distributions for concrete, asphalt, and road base applications.
Construction aggregate typically requires material with a particle size ranging from coarse gravel (e.g., 20-40 mm) down to fine sand (0-5 mm) and even finer filler powder (e.g., 0-0.075 mm). While primary crushing and secondary crushing handle the coarse stages, grinding mills are often deployed to produce fine sand (< 5 mm) or limestone powder for use as mineral filler, cement additive, or in manufacturing artificial sand. In Algeria, many aggregate producers operate at a moderate capacity of 5 to 10 tons per hour, where mobile or compact grinding solutions can be effectively integrated into existing crushing plants.
The selection of a suitable grinding mill depends on several factors: feed size, required product fineness, moisture content, abrasiveness of limestone, and operational cost. For limestone with a Mohs hardness of 3-4, open-circuit or closed-circuit grinding with a medium-speed mill is often optimal. A throughput of 5-10 t/h is well-matched with small to medium-sized mills that offer both flexibility and energy efficiency.
Shanghai Zenith Machinery Co., Ltd. is an excellent manufacturer of ore grinding equipment in China, having made great achievements in the field of ultra-fine powder grinding. Specialized in the research, development, and production of industrial powder grinding equipment and other related devices, Zenith offers a comprehensive range of mills including MTW Trapezium Grinding Mill, MTM Medium-Speed Grinding Mill, Raymond Mill, LM Vertical Grinding Mill, and LUM Ultrafine Vertical Mill. With decades of experience and thousands of installations worldwide, Zenith provides reliable and cost-effective solutions for the Algerian aggregate industry.
For the specific capacity requirement of 5-10 tph for limestone grinding in Algeria, we recommend two proven and efficient models: the MTW110Z Trapezium Grinding Mill and the MTM130 Medium-Speed Grinding Mill. Both models are widely used in similar applications around the world and are known for their robust construction, low maintenance cost, and excellent product quality.
The MTW series is a flagship product of Zenith, featuring multiple patents. The trapezium-shaped grinding rollers and rings enhance grinding efficiency and reduce energy consumption. The MTW110Z model offers a capacity range of 3-10 t/h, making it an ideal choice for the 5-10 t/h target. It can produce final product sizes from 1.6 mm down to 0.045 mm (325 mesh), which covers both sand and powder applications for construction aggregate. The integrated classifier ensures precise particle size control.
Another excellent option is the MTM130, which adopts world-leading powder processing technology. It is an upgraded version of traditional Raymond mills, with higher efficiency and lower energy consumption. The MTM130 can process limestone with a feed size up to 30 mm and deliver a capacity of 6-11 t/h, comfortably fitting the 5-10 tph window. The final fineness can be adjusted between 1.6 mm and 0.045 mm, providing flexibility for different aggregate specifications.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor Power (kW) | Fan Motor Power (kW) |
|---|---|---|---|---|---|
| MTW110Z | <30 | 1.6 – 0.045 | 3 – 10 | 55 | 55 |
| MTM130 | <30 | 1.6 – 0.045 | 6 – 11 | 75 | — (main unit integrated) |
Note: The MTM130’s main motor power is 75 kW; the fan motor specifications can be customized per installation.
Consider a typical limestone quarry in the Setif or Constantine region of Algeria. The raw limestone is first crushed by a jaw crusher and then a cone crusher to a size of ≤30 mm. This pre-crushed material is fed into an MTW110Z mill. The mill produces fine limestone powder (0-0.6 mm) which is used as mineral filler in asphalt concrete, while the coarser fraction (0.6-1.6 mm) is blended with crushed sand for concrete production. With the mill operating at a steady 7 t/h, the plant meets the local construction demand efficiently. The built-in dust collector and low noise operation comply with Algerian environmental regulations.
Both the MTW110Z and MTM130 are designed for easy installation and maintenance. The compact footprint saves valuable floor space, especially when integrated into existing crushing circuits. The grinding rollers and rings are made of high wear-resistant alloy steel, extending service life and reducing downtime. In addition, the automatic lubrication system and intelligent control panel allow operators to monitor and adjust parameters remotely, minimizing manual intervention. For the Algerian climate, which can be hot and dusty, the sealed bearing design and efficient dust extraction ensure reliable operation even under harsh conditions.
Algeria’s growing construction sector demands reliable and efficient limestone grinding solutions for aggregate production. With a capacity range of 5-10 tph, the MTW110Z Trapezium Grinding Mill and MTM130 Medium-Speed Grinding Mill from Shanghai Zenith Machinery are the perfect choices. Their proven performance, robust build, and cost-effective operation ensure that limestone can be processed into high-quality construction aggregate with minimal environmental impact.
