High-efficiency, premium heavy-duty process pumps and air blower packages deployed globally in large-scale mineral processing operations.
Chile, as the global epicenter of copper mining and lithium production, presents some of the most punishing environments for fluid transport machinery. Operating mainly in the high-altitude Andean Cordillera, such as the Antofagasta and Atacama regions, mining systems handle extremely dense ore pulps, abrasive quartz-rich tailings, and highly acidic process media. Traditional metal-lined and rubber-lined pumps suffer from rapid degradation, cavitation, and erosion-corrosion cycles, leading to unscheduled shutdowns and high operational costs.
With water scarcity driving the industry to recycle process water or pump desalinated seawater uphill from the coast, the chemical composition of slurries has become increasingly aggressive. The mixture of high salinity, chemical reagents, and coarse solids demands a paradigm shift in materials science. Specialized ceramic slurry pumps utilizing Silicon Carbide (SiC) and Alumina composite liners have emerged as the definitive solution to maximize equipment uptime in these demanding operations.
Under the high-velocity impact of copper concentrate and coarse tailings (typically containing over 60% solids by weight), metallic oxide layers (such as those on high-chromium alloys) are instantly stripped away. This exposes fresh metal to immediate chemical attack by acid and chloride-heavy process waters.
Specialized ceramics, with an industrial hardness second only to diamond (reaching Mohs 9.5), exhibit absolute chemical inertness to acids and brine solutions, providing a wear-life 4 to 8 times longer than Cr27/high-chrome irons.
| Material Type | Mohs Hardness | Average Wear Life (Months) |
|---|---|---|
| High Chrome Alloy (Cr27) | 6.5 - 7.0 | 3 - 6 Months |
| Natural Rubber / Elastomer | 3.0 - 4.0 | 4 - 8 Months |
| Sintered Silicon Carbide | 9.2 - 9.5 | 18 - 36 Months |
Understanding the engineering behind our ceramic solutions designed for mining mills and tailings transport.
Our pump wet-end components (volute liners, impellers, throatbushes) are cast using advanced reaction-bonded or sintered Silicon Carbide. This ensures zero porosity, complete acid/alkali tolerance, and superior resistance to high-velocity particle impact.
Mean Time Between Failures (MTBF) is extended up to 300% compared to traditional metallic slurry pumps. This structural longevity drastically minimizes down-time losses in copper concentrators and continuous flotation cells.
Precision-molded ceramic impellers feature perfectly smooth interior surfaces, reducing fluid frictional losses. This increases hydraulic efficiency by 3% to 7%, translating to significant electrical energy savings on megawatt-scale motor drives.
Over 50 Years of Engineering Excellence, Scientific Innovation, and Worldwide Infrastructure Supply.
Shandong Zhangqiu Blower Co., Ltd. (formerly known as Shandong Zhangqiu Blower Works) has established itself as an industrial titan, with over 50 years of engineering, manufacturing, and R&D experience. ZCBC operates two Sino-Japanese Joint-Ventures and one USA-based subsidiary, marking it as the first company in China’s blower and industrial fluid machinery industry to build overseas branches. Our strategic corporate vision—"Develop main business, pioneer new fields and innovate, cooperate to be a great company"—fuels our relentless commitment to engineering quality.
Today, ZCBC is a modern enterprise integrating mechanical design, precision manufacturing, and international sales. Our production lines cover Roots Blowers, Centrifugal Blowers, Industrial Fans, Specialized Slurry Pumps, Desulfurization Pumps, Pneumatic Conveying Systems, Electrical Control Equipment, MVR Evaporators, and Water Treatment Systems. In July 2011, ZCBC was listed on the Shenzhen Stock Exchange (Stock Code: 002598), solidifying our financial stability and capacity to invest in state-of-the-art technological R&D.
ZCBC’s parent company generates an operating income of 1.5 billion yuan and a profit of 150 million yuan (including joint ventures). The company owns 20 holding companies and operates four manufacturing bases across China (Jiangsu Wuxi, Guangdong Dongguan, Hunan Chenzhou, Gansu Jinchang), supported by four dedicated R&D centers in Beijing, Shanghai, Shijiazhuang, and Wuxi.
Cost Control, Manufacturing Scale, and Advanced Metallurgy Delivered to Chile's Mining Districts.
For international copper miners operating in Chile, selecting a reliable supply chain partner is as critical as selecting the equipment itself. ZCBC leverages the unparalleled efficiency of China's industrial manufacturing ecosystem. Operating from a newly built, high-standard modern industrial park spanning over 430,000 square meters, we integrate vertical raw material sourcing, automated precision casting, and advanced quality verification. This ensures our ceramic slurry pumps are manufactured with higher consistency and significantly lower lead times compared to Western brands.
Our facility features advanced processing and testing equipment, including CNC machining centers, five-axis machining tools, three-coordinate coordinate measuring machines (CMM), and ultrasonic flaw detectors imported from Japan and Germany. By utilizing a Product Lifecycle Management (PLM) system combined with Computer-Aided Manufacturing (CAM) and Computer-Aided Testing (CAT), we accelerate engineering design cycles and guarantee that every ceramic component achieves a micron-level dimensional tolerance.
This high-precision manufacturing capacity is backed by a robust talent network. ZCBC employs an elite scientific research team composed of experts receiving special allowances from the State Council, along with senior doctorate-level researchers. We have established close partnerships with premier academic institutions, including Tsinghua University, Xi'an Jiaotong University, the China University of Mining and Technology, and Shandong University. This ensures that every slurry pump is hydrodynamically optimized for the slurry rheology specific to the Chilean Andes.
Reliability in mining operations requires fast local response times. ZCBC supports its international clients with dedicated engineering resources. Our design team can provide 3D pump and pipe layout drawings within 24 hours based on layout drafts or images sent from the field. This capability allows Chilean mine planners to easily retrofit existing pump stations with ZCBC’s specialized ceramic wear components.
ZCBC meets rigorous international regulatory standards, ensuring compliance with local environmental and safety requirements in Chile. Our management and manufacturing processes are certified to ISO 9001 (Quality Management), ISO 14001 (Environmental Management), ISO 50001 (Energy Management), and ISO 10012 (Measurement Management). Furthermore, our equipment holds CE certification, energy-saving certificates, and the Mining Product Safety Mark, satisfying the strictest requirements of major global mining houses.
Deploying specialized ceramic solutions in key minerals processing circuits across Chile.
Pumping underflow mill discharge slurries with high solids concentrations (up to 65% w/w) and large particles (d50 > 150 microns). Silicon Carbide liners withstand high-velocity sliding abrasion and impact.
Handling chemical froths loaded with xanthates, sulfates, and acidic water. The chemical inertness of ceramic slurry pumps prevents chemical erosion and ensures consistent hydraulic profile stability.
Moving large volumes of fine tailings to disposal ponds over long distances. High pump pressures and abrasive particles degrade traditional metals, while ceramics maintain stable clearances to prevent backflow and preserve efficiency.
For large EPC contractors and mining operators, procurement criteria extend beyond pump performance. It involves compliance with rigorous corporate standards for supply chain logistics, engineering documentation, and manufacturing transparency. ZCBC addresses these requirements by providing full material traceabilities, hydrostatic and dynamic balance test certificates, and complete performance testing curves from our automated water-testing facilities.
Our products are exported to more than 70 countries and regions, including the United States, Germany, and Italy. With a dedicated foreign trade corporation and a branch office in the USA, we understand the logistical requirements for shipping to major Chilean ports such as Antofagasta, Valparaíso, and Iquique. ZCBC manages transport details, export packaging, and customs clearance support to ensure on-time delivery to remote mine sites.
