Recently, the two high-standard aggregate production lines (400 tons per hour each) contracted and constructed by Guangdong HPower Mining Equipment Co., Ltd. (hereinafter referred to as HPower Mining) in Guinea have completed full installation, commissioning and trial production, and officially entered mass production. The combined total capacity of the dual lines reaches 800 tons per hour. As a landmark benchmark project of HPower Mining for deep cultivation of the African market and supporting infrastructure construction in West Africa, the project adopts customized crushing and shaping technologies for high-end complete sets of equipment to stably produce high-quality sand and aggregate on a large scale, powering the large-scale manufacturing of high-standard aggregates in local Guinea.
Rooted in Core West African Market, Precisely Meeting Surging Infrastructure Demand
Guinea is a resource-rich West African country endowed with abundant mineral resources. In recent years, rapid urbanization has brought a spate of infrastructure projects covering highways, railways, housing construction, water conservancy and other fields, driving skyrocketing market demand for high-quality, high-specification sand and aggregates. For a long time, local sand and aggregate production has adopted extensive and outdated modes with backward crushing equipment and simplistic technological processes. The finished aggregates suffer from high flaky and elongated particle ratios, discontinuous gradation and inconsistent quality, while aggregates dedicated to high-grade engineering projects largely rely on costly imports with unstable delivery cycles, severely delaying the construction progress of local infrastructure.
With over 20 years of R&D and manufacturing experience in mining crushing equipment, technological strengths as a national high-tech enterprise, and mature experience from overseas projects covering more than 50 countries worldwide, HPower Mining identified local market pain points and supply-demand imbalances. The company tailor-made two independent 400t/h premium aggregate production lines for Guinean clients, forming a combined total capacity of 800 tons per hour through coordinated operation. Upon full commissioning, the project can fully satisfy the aggregate demand of large-scale local infrastructure in Guinea, with finished aggregates also exportable to neighboring West African nations including Mali and Senegal. It improves the regional supply chain of sand and building materials and lays a solid raw material foundation for large-scale infrastructure development across West Africa.
Full Set of Independent R&D Core Equipment, Optimized Process Delivers Superior High-Standard Aggregate Capacity
Both production lines adopt a proven full-process technical route: primary crushing → secondary crushing → shaping → multi-stage screening. All core main machines are flagship models independently developed by HPower Mining, balancing three core advantages: ultra-large processing capacity, excellent aggregate particle shape and long-term stable continuous operation. Key configuration details for one single 400t/h production line are listed as follows:
-
Primary Crushing Unit: C110 Jaw Crusher Serving as the primary core equipment at the feed end of the whole line, the C110 jaw crusher is specially adapted for crushing hard raw stones such as granite and basalt. Equipped with a heavy-duty cast steel integrated frame and high-wear-resistant crushing liners, it features a large feed opening and high crushing ratio, efficiently processing oversized raw ores and producing evenly sized semi-finished coarse materials to guarantee stable overall line capacity.
-
Secondary Crushing Unit: HP5 Multi-Cylinder Hydraulic Cone Crusher Designed for secondary crushing of high-hardness ores, it operates on the interparticle crushing principle and integrates hydraulic cavity clearing and automatic overload protection systems. It delivers outstanding crushing efficiency, effectively cutting the proportion of flaky and elongated aggregates to form regular, smooth finished particles while greatly reducing wear loss of vulnerable parts, making it ideal for long-duration full-load continuous operation in overseas sites.
-
Shaping Unit: PFS1715 High-Power Three-Chamber Vertical Shaft Impact Crusher The core polishing and quality-upgrading equipment for finished aggregates, its unique vortex crushing chamber and three-stage crushing structure integrate fine secondary crushing and aggregate shaping functions. It further refines and optimizes particle materials discharged from the cone crusher, greatly boosting aggregate roundness and optimizing particle gradation. All indicators of finished products fully meet the usage specifications of high-standard engineering including expressways and large bridges.
-
Screening Unit: 3075 Double-Shaft Vibrating Screen + 2460 Vibrating Screen Combined large and small screens form a multi-stage grading screening system. The high-throughput 3075 double-shaft vibrating screen undertakes main screening tasks with large handling capacity and high screening efficiency; the 2460 vibrating screen performs fine sorting to accurately separate finished sand and aggregates of various sizes, ensuring clean classification and uniform particle size to satisfy diversified material demands of different engineering scenarios.
Overcoming Difficulties for Smooth Delivery & Commissioning; Chinese Intelligent Manufacturing Continues to Penetrate African Overseas Markets
Since project signing, HPower Mining has coordinated full-chain services including production scheduling, cross-border ocean shipping and on-site installation & commissioning guidance by professional technical teams. The team overcame numerous obstacles such as hot and rainy complex climates in West Africa, lengthy ocean logistics cycles, crude wild construction sites and inconvenient supply of supporting materials. The whole process covering equipment factory inspection, cross-border shipment and on-site assembly was strictly controlled in line with international engineering construction standards. Engineers provided one-on-one guidance for installation alignment, pipeline layout and equipment leveling, inspected installation precision machine by machine, and debugged linkage logic of the complete technological flow. All civil construction work for the two production lines has been finished, followed by successful no-load single-machine debugging and full-line linkage test runs with all operating parameters qualified. The project is now officially commissioned and running continuous mass production.
As a benchmark domestic enterprise providing complete set solutions for sand and mining equipment, HPower Mining boasts core competitiveness including integrated whole-line delivery, stable equipment performance, outstanding comprehensive cost performance and closed-loop full-cycle pre-sales and after-sales services. The smooth commissioning of this dual 800t/h high-standard aggregate project in Guinea marks another typical practice of HPower Mining’s "Chinese Intelligent Manufacturing Going Global" strategy. Moving forward, HPower Mining will further deepen its layout in Africa’s sand and mineral market. Relying on customized crushing and sand-making solutions, self-developed high-end main equipment and localized operation & maintenance service systems, the company will help more overseas clients solve bottlenecks of low efficiency and poor aggregate quality at crushing plants. It will continuously export premium complete mining technologies and equipment, contributing the power of Chinese manufacturing to global infrastructure development.
