Discover our heavy-duty industrial series manufactured under state-of-the-art standards. Designed to withstand severe abrasion and chemical corrosion in global mineral processing applications.
In modern mineral processing plants, lead and zinc mineral extraction relies on sophisticated chemical flotation techniques, gravity separation, and hydrocyclone classification. The resulting slurries are extremely demanding on pumping systems due to the sharp, high-density solids generated during crushing and grinding circuits. Lead ore (Galena, PbS) has a high specific gravity of approximately 7.5, while zinc ore (Sphalerite, ZnS) has a specific gravity of around 4.0. Moving these heavy particles in a fluid medium requires pumps engineered for both high hydraulic efficiency and outstanding mechanical endurance.
Traditional slurry pumps suffer rapid hydraulic degradation. High-pressure impact at the impeller inlet, combined with chemical attack from flotation reagents (collectors, frothers, and modifiers like copper sulfate and xanthates), leads to rapid pitting, cavitation, and wall thinning. Consequently, modern heavy industry is moving toward Silicon Carbide (SiC) Ceramic Slurry Pumps. Silicon carbide exhibits a hardness second only to diamond, providing wear resistance 3 to 5 times greater than that of high-chrome alloys.
Lead-zinc slurries carry heavy particles that cause extreme wear. Our specialized ceramic coatings prevent micro-cutting and mechanical erosion in high-velocity zones.
Strong acids, alkalis, and complex copper/zinc flotation collectors require chemically inert wetted parts to prevent accelerated galvanic corrosion.
Preventing unexpected down-time through mechanical design optimizations like double-suction balance, advanced mechanical sealing, and thermal monitoring.
Shandong Zhangqiu Blower Co., Ltd. (formerly known as Shandong Zhangqiu Blower Works) has over 50 years of experience in blower design, engineering, and manufacturing. As the leading enterprise in China's blower industry, we maintain top-ranked domestic market occupancy for Roots blowers.
Our overall development strategy is to “develop main business, pioneer new fields and innovate, cooperate to be a great company”. Guided by our work concept of "do the best," we are a modern corporation integrating design, manufacturing, and sales of Roots blowers, centrifugal blowers, fans, industrial slurry/water pumps, pneumatic conveying systems, electrical equipment, and MVR (Mechanical Vapor Recompression) evaporation and crystallization systems.
In July 2011, the company was officially listed on the Shenzhen Stock Exchange (Stock Code: 002598). By 2020, our parent company realized an operating income of 1.5 billion yuan with a profit of 150 million yuan. Today, ZCBC operates 20 holding companies with four manufacturing bases in Wuxi (Jiangsu), Dongguan (Guangdong), Chenzhou (Hunan), and Jinchang (Gansu), supported by R&D centers in Beijing, Shanghai, Shijiazhuang, and Wuxi.
International mining operations face pressure to lower total cost of ownership (TCO) while complying with strict environmental and safety standards. Major lead-zinc producers in Australia, Canada, Peru, China, and South Africa require robust equipment that offers maximum run-time and low maintenance costs.
Modern processing plants are adopting IoT sensors on pumping systems to track real-time vibration, casing temperature, seal leakage, and hydraulic pressure. This allows operators to perform predictive maintenance before catastrophic wear occurs, avoiding costly unplanned downtime in flotation operations.
Lead-zinc froth flotation relies heavily on controlled air injection. Roots blowers, centrifugal blowers, and air-foil bearing blowers must supply consistent, oil-free low-pressure air. These systems prevent gas dispersion fluctuations, ensuring maximum bubble attachment and mineral recovery.
Furthermore, water management has become critical. Zero Liquid Discharge (ZLD) regulations require advanced treatment of tailing wastewater. ZCBC addresses these environmental needs by offering complete systems featuring Mechanical Vapor Recompression (MVR) evaporation, concentration, and crystallization. This allows lead-zinc concentration facilities to recycle up to 95% of process water while recovering valuable byproducts.
ZCBC is a leading manufacturer of Roots blowers, centrifugal blowers, vacuum pumps, industrial pumps, and pneumatic conveying systems. As a key drafter of national standards for Roots blowers in China, we are committed to engineering excellence.
Equipped with nearly 100 sets of advanced machinery—including CNC machining centers, five-axis machining centers, three-coordinate measuring instruments, and ultrasonic flaw detectors imported from Japan and Germany—we ensure precise manufacturing tolerances. We implement Product Lifecycle Management (PLM), Computer-Aided Manufacturing (CAM), and Computer-Aided Process Planning (CAPP) systems to shorten design cycles and maintain consistent product quality.
Our dedicated research team includes senior engineers and industry experts supported by a postgraduate workstation. We collaborate closely with top academic institutions—including Tsinghua University, Xi'an Jiaotong University, China University of Mining and Technology, and Shandong University—to keep our fluid machinery technology at the forefront of the industry.
ZCBC has been authorized with 69 patents (including 5 invention patents) and holds ISO9001, ISO14001, ISO50001, and ISO10012 certifications. Our mining products carry safety marks, CE compliance, and mandatory 3C certifications.
To serve global mining projects, ZCBC has established a robust international sales and support network. In addition to our joint ventures and overseas branches in the United States, we export our products to more than 70 countries and regions—including Germany, Italy, Russia, Australia, and Brazil.
We understand that each mine has unique operational conditions. Our engineering team can provide custom 3D CAD drawings within 24 hours based on customer-submitted sketches or process flow diagrams. This ensures seamless integration into existing pipelines and structural footprints. Additionally, all mechanical components comply with localized environmental and safety standards, such as the US Environmental Protection Agency (EPA) guidelines, CE machinery directives, and ATEX certifications for explosive dust atmospheres commonly found in deep underground mines.
Our localized branch networks facilitate fast spare parts distribution and field engineering support, reducing lead times for critical maintenance.
Equipment is certified for mining applications, featuring explosion-proof motors, pressure-tested casings, and reliable slurry seals.
We provide complete design, installation, commissioning, and operation services for wastewater treatment, pneumatic conveying, and MVR evaporation projects.
