A major iron ore mine faced challenges of low resource utilization and poor economic returns. Its ore is a complex mixed type containing multiple minerals such as magnetite, hematite, and limonite. Traditional magnetic separation processes could only effectively recover strongly magnetic magnetite, while large quantities of weakly magnetic hematite and limonite were lost with the tailings, resulting in resource waste and operational losses.
Solution and Core Equipment
To address this challenge, the project team introduced an advanced “ultrafine grinding-high-gradient magnetic separation” combined process. Its core equipment is the high-gradient magnetic separator, featuring two prominent characteristics:
High field strength and high gradient: Generates a magnetic field far exceeding conventional separators, exerting powerful magnetic attraction on fine-grained weakly magnetic minerals.
Precision Capture: Specifically targets finely ground, fully liberated micro-sized hematite and limonite for highly efficient recovery.
Outstanding Advantages and Implementation Outcomes
This solution delivered significant technical and economic benefits:
Substantially Enhanced Resource Recovery: Post-upgrade, the comprehensive iron metal recovery rate saw a marked improvement, yielding over 150,000 tons of additional iron concentrate annually—transforming former “waste” into valuable resources.
Substantial Economic Benefits: The project generates substantial annual profits for the mine while significantly reducing environmental impact and tailings pond maintenance costs through decreased tailings discharge.
Broad Technical Adaptability: This successful case provides an efficient, reliable technical pathway for processing similarly complex, difficult-to-process ores, demonstrating the immense potential of advanced magnetic separation technology.
This case demonstrates that selecting high-performance magnetic separators tailored to specific mineral characteristics can effectively overcome bottlenecks in traditional processes. It represents a key technology for achieving efficient and clean utilization of mineral resources, possessing high value for widespread adoption.

Background:
A specialty ceramic materials manufacturer faced severe powder mixing challenges during production of new high-hardness ceramic cutting tools. The formulation included alumina, silicon carbide, and multiple trace metal binders—materials with vastly differing densities, extremely low trace component ratios, and stringent uniformity requirements. The conventional mixer previously used frequently resulted in localized clumping and uneven component distribution. This led to hard spots and brittle layers within the sintered ceramic parts, causing the product yield rate to drop below 85%.
Solution:
The manufacturer introduced a three-dimensional motion mixer. This equipment employs active tilting, rotation, and translational multi-dimensional compound motion to achieve comprehensive “turbulent" diffusion and convection of powders within the mixing vessel. To address the tendency for clumping, the customer selected an integrated crushing device that breaks down soft agglomerates during mixing. The entire mixing process occurs in a fully sealed environment, preventing foreign material ingress and dust leakage.
Results and Value:
Quality Enhancement: Mixing uniformity (CV value) improved from over 15% to a stable level below 5%, with exceptionally even distribution of trace components.
Yield Leap: Post-sintering yield for ceramic tools surged from 85% to over 98%, significantly enhancing performance consistency.
Efficiency and Cost: Mixing cycles shortened by 30%, while reducing costs from material waste and rework. Annual production cost savings are projected to exceed 200,000 yuan.
Cleanliness and Safety: The sealed design enables dust-free operation, meeting cleanroom requirements and improving the working environment for employees.
This case demonstrates that targeted, high-efficiency mixing solutions are a critical factor in enhancing the quality and production efficiency of high-end powder materials.

A medium-sized feed production enterprise utilized traditional bucket elevators within its existing production line to transport crushed corn meal to mixers. However, this equipment presented multiple issues: poor sealing led to severe dust leakage and harsh working conditions; residue accumulation during elevation caused cross-contamination between feed batches; and high operational noise levels coupled with frequent malfunctions impacted overall production efficiency and product quality.
To address these issues, the company implemented a technical upgrade by installing an LS315 shaftless screw conveyor as the vertical lifting solution. This model's core advantage lies in its seamless steel tube housing paired with shaftless spiral blades. During installation, engineers designed a 70-degree inclined configuration reaching 15 meters in height to perfectly meet vertical lifting requirements based on the site's spatial constraints.
The results were immediately evident upon commissioning. First, its fully enclosed structure completely eliminated dust leakage, fundamentally improving the workshop environment. Second, the shaftless design prevented residue buildup during the conveyance of viscous, easily entangled corn flour, effectively avoiding cross-contamination between batches and ensuring the precision of feed formulations. Additionally, the equipment operates smoothly with significantly reduced noise and simplified maintenance, requiring only periodic inspections of blade wear.
This upgrade not only reduced energy consumption in this section by approximately 15% but also increased conveying efficiency by 20%. It ensures continuous and stable feed supply to subsequent mixing processes, laying a solid foundation for cleaner and more efficient production at the enterprise.

Case Background
A craft brewery initially used a flexible screw conveyor to handle grains and malt raw materials. However, the equipment long suffered from severe wear, material leakage, and high maintenance costs. The PVC delivery pipe was prone to cracks due to abrasion from the spiral drill, requiring frequent repairs with tape by staff. Despite these efforts, material accumulation and contamination risks persisted, significantly impacting production efficiency and hygiene safety.
Solution: Upgrading to the Screw Auger Feeder System
To thoroughly address these issues, the brewery introduced a high-performance Screw Auger Feeder system, with core improvements including:
Structural Optimization: Adoption of a shaftless spiral design (for sticky and wet materials) and a stainless steel pipe body to prevent material entanglement and pipe wall wear.
Sealing and Pressure Resistance: Enhanced shell sealing design to prevent air leakage and material spillage, supporting high-pressure dense-phase pneumatic transportation suited to the brewery’s high-pressure environment.
Intelligent Control: Integration of variable frequency motors and sensors to achieve quantitative delivery (with precision up to 0.5%) and automated flow adjustment to match production line demands.
Implementation Results
Efficiency Improvement: Delivery capacity was upgraded from the original equipment’s susceptibility to clogging to a stable transportation rate of 6 tons/hour (Model SC-6T), meeting the brewery’s expansion needs.
Cost Reduction: The maintenance cycle was extended to over six months, eliminating raw material waste caused by leakage and reducing annual maintenance costs by 40%.
Safety and Hygiene: The fully enclosed stainless steel structure complies with food-grade GMP standards, avoids cross-contamination, and allows quick switching of material formulas via the CIP online cleaning system.
Industry Insights
The Screw Auger Feeder addresses the application bottlenecks of traditional screw conveyors in the food industry through sealing design, material innovation, and intelligent control. Its modular structure (e.g., addable inlets/outlets) further supports flexible expansion of production lines, making it a preferred solution for powder and particle transportation in industries such as chemicals and pharmaceuticals.
Industry Pain Points:
A chemical plant generated large amounts of corrosive and mildly toxic powdered waste during production. Previously, the waste was manually bagged and transported to the disposal area. This method was not only inefficient and labor-intensive but also posed health and safety risks to workers due to direct exposure. Additionally, spillage during handling caused secondary contamination of the plant environment.
Solution:
To achieve automated and enclosed waste handling,In our customer side, the plant installed a corrosion-resistant shaftless screw conveyor. This solution was selected based on the following considerations:
Superior Shaftless Design: The powdered waste was prone to sticking and tangling, which often caused blockages in traditional shafted conveyors. The shaftless screw conveyor eliminates central shaft obstruction, ensuring smooth material flow and virtually no clogging, enabling continuous operation.
Excellent Sealing and Corrosion Resistance: The trough is made of specially treated stainless steel, effectively resisting chemical corrosion. The fully enclosed process prevents any leakage of hazardous materials, ensuring operator health and safety.
Precise Directed Conveying: The conveyor directly transfers waste from the generation point to a sealed treatment tank, achieving automated "point-to-point" flow without manual intervention or intermediate exposure.
Application Results:
After the installation of the screw conveyor system, the waste handling process at the chemical plant was fundamentally transformed. Safety was significantly enhanced by completely eliminating manual contact risks. Efficiency increased severalfold thanks to continuous automated operation. Moreover, the plant environment became cleaner without secondary pollution. The project manager commented: "It is not just a conveyor—it is an essential guardian for achieving green and safe production, truly turning troublesome 'waste' into manageable 'treasure'."
