Deploy high-durability and energy-efficient solutions for the complex slurry transportation and aeration tasks typical of modern Indian flotation cells.
India is experiencing an unprecedented industrial expansion. Rapidly rising demand for steel, aluminum, and electricity has driven massive volume increases in iron ore flotation, bauxite extraction, copper concentration, and coal washing. Industrial zones across Odisha, Jharkhand, Chhattisgarh, and Karnataka are operating under strict operational efficiency targets to keep up with national demand.
However, processing low-grade minerals requires advanced flotation systems that generate substantial froth. Standard heavy-duty slurry pumps consistently fail under these conditions. Entrained air forms a dense pocket at the eye of the impeller, causing air locks, surging discharge, and hopper overflows. This leads to costly downtime, loss of valuable minerals, and increased maintenance overheads.
To solve this, industrial operators require specialized Foam Slurry Pumps. Engineered with an open conical hopper and a unique tangential inlet, these pumps allow frothy slurry to enter the impeller smoothly while venting out trapped air, ensuring continuous slurry handling and process stability.
Indian processing environments present severe abrasiveness and chemical corrosiveness. Traditional high-chrome cast iron impellers and liners wear down rapidly in acidic flotation circuits or high-silica coal slues, requiring replacements every few months.
Shandong Zhangqiu Blower Co., Ltd. addresses this challenge by pioneering ceramic slurry pump technologies (exemplified by the TZJK-TD series ceramic slurry pump). Silicon carbide composite liners offer up to 4 times the service life of metal liners in highly corrosive and abrasive duties. This significantly reduces the Total Cost of Ownership (TCO) for mineral processing operations.
For operations requiring metallic systems, our high-chrome alloy impellers are manufactured with proprietary countercurrent cooling and anti-sticky wear technologies, assuring maximum uptime and structural reliability.
Our manufacturing scale and performance statistics highlight our capability to support heavy industrial infrastructure worldwide.
Shandong Zhangqiu Blower Co., Ltd. (formerly known as Shandong Zhangqiu Blower Works) is a leading manufacturing enterprise with over 50 years' blower design and manufacturing experience. We have set up two Sino-Japanese Joint-ventures and one USA branch, becoming the first company in the Chinese blower industry to establish an overseas branch. We are the leading enterprise in the Zhangqiu local industry, and our main product, the Roots Blower, occupies a top rank in the domestic market.
Our overall developing strategy is centered around the concept: “Develop main business, pioneer new fields and innovate, cooperate to be a great company”, paired with our core working concept, “Do the best”. Today, we are a modern company integrated in the design, manufacturing, and sales of high-performance Roots Blowers, Centrifugal Blowers, Industrial Fans, Slurry Pumps, Pneumatic Conveying Systems, MVR Evaporator systems, Concentration and Crystallization plants, and Environmental Waste Water Treatment solutions.
In 2005, the company relocated to a newly built, high-standard modern industrial park spanning 430,000 square meters. The facility provides an advanced manufacturing space equipped with cutting-edge machining systems.
On July 7th, 2011, the company was officially listed on the Shenzhen Stock Exchange (Stock Code: 002598), representing a major milestone. By 2020, our parent company realized an operating income of 1.5 billion yuan and a profit of 150 million yuan. Currently, Zhang Drum company controls 20 holding companies, with four key manufacturing bases located in Wuxi (Jiangsu), Dongguan (Guangdong), Chenzhou (Hunan), and Jinchang (Gansu), alongside four dedicated R&D centers in Beijing, Shanghai, Shijiazhuang, and Wuxi.
ZhangGu company is the executive director of the China General Machinery Industry Association and the vice president unit of the Fan Branch. We are the primary drafting unit of national standards for Roots Blowers, highlighting our engineering authority.
In recent years, our R&D teams have secured 69 authorized patents (including 5 invention patents) and 2 copyrights. Key proprietary technologies include countercurrent cooling, fan noise reduction, anti-sticky wear surfaces, special seals, grease lubrication systems, and twisted-leaf impeller designs. Our manufacturing processes are certified under ISO9001, ISO14001, ISO50001, ISO10012, occupational health systems, CE, and the Safety Mark for Mining Products.
We provide complete 3D CAD modeling within 24 hours of customer drafts, ensuring proper alignment with existing pipelines and layout restrictions before casting.
All pumps and blower casings undergo hydrostatic, dynamic balance, and non-destructive ultrasonic flaw detection before leaving the production line.
We offer local technical engineers, installation supervisors, and testing personnel on-site in major Indian mining regions for commissioning support.
Equipped with high-precision CNC machining centers, five-axis machining tools, and computer-aided testing facilities.

Handling flotation froth is a complex fluid dynamics challenge. In mineral beneficiation processes like froth flotation for copper, lead, zinc, or iron, chemical reagents generate a highly stable, mineral-laden froth. When this fluid enters standard centrifugal pumps, the mechanical shear causes air bubbles to separate from the liquid phase. These air bubbles collect in the center of the impeller, creating an air pocket that restricts the flow of slurry. This causes pump surging, flow loss, and potential hopper overflow.
Our Foam Slurry Pumps address this problem with an integrated engineering system. The key components include:
This design maintains stable flow rates and consistent pump performance, eliminating the surging and priming issues that disrupt mineral recovery circuits.
Beyond slurry pumps, Shandong Zhangqiu Blower provides aeration support for flotation circuits using our high-efficiency roots and centrifugal blowers. High-pressure tri-lobe roots blowers (such as our ZG Series) and high-speed centrifugal systems provide precise, oil-free aeration to maintain consistent bubble generation in the flotation cell.
By coordinating the foam slurry extraction pumps with stable air supply systems, operators can control the size, density, and flow rate of flotation bubbles. This balance is critical for optimizing grade recovery in modern gold, copper, and iron processing facilities.
