The FD Series Cone Classifier introduces innovative desliming technology that transforms fine particle separation in mineral processing operations. This system creates exceptional settling efficiency through its conical design, addressing common classification challenges while enhancing recovery of valuable minerals. Its balanced approach to slurry processing delivers consistent results across varying ore conditions, making it valuable desliming equipment that adapts to diverse processing requirements without compromising separation precision or throughput capacity.
Features & Technical Advantages
Our proprietary conical structure creates ideal settling conditions through precisely engineered hydraulic flow patterns. This design maximizes separation efficiency while preventing short-circuiting, resulting in superior control of particle size distribution in overflow and underflow streams.
Achieves desliming efficiency of 33-45% while maintaining high throughput, effectively removing fine clay particles and slimes that can interfere with downstream processing. This significantly improves recovery rates and concentrate quality in subsequent beneficiation stages.
With settling areas ranging from 0.75 to 7 square meters and processing capacities from 2 to 2.16 t/m² h for coarse materials, our cone classifiers can handle operations from small plants to large industrial complexes with exceptional reliability.
Maintains stable underflow density in the 40-60% solids range, providing optimal feed consistency for downstream processes such as grinding circuits and flotation cells, while ensuring efficient operation without plugging or dilution issues.
Dedicated discharge configuration enables excellent control over the separation process, optimizing valuable mineral recovery while effectively removing unwanted fine particles. Adjustable parameters allow fine-tuning for various ore types.
Manufactured from high-quality wear-resistant materials, our cone classifiers are designed to provide extended service life in harsh mining environments, reducing maintenance requirements and operational downtime.
Our optimized design minimizes energy consumption while maintaining excellent desliming performance, reducing operational costs throughout the processing circuit. The gravity-based separation principle requires minimal external energy input.

Frequently Asked Questions
Cone classifier separation efficiency is influenced by several key factors: feed particle size distribution, feed solids concentration, settling area, residence time, feed flow rate, classifier geometry (diameter, cone angle), and material characteristics. These parameters need to be carefully considered and adjusted according to specific application requirements to achieve optimal performance.
Selection depends on multiple factors: required processing capacity (t/h), target cut point, feed material characteristics, settling area requirements, and space constraints. Key specifications include the classifier diameter, settling area, and volume. Our engineering team can help determine the optimal model based on your specific processing needs and material analysis.
Regular maintenance includes inspecting wear components (especially discharge pipes and valves), monitoring discharge concentration and flow rates, checking for abnormal buildup or blockages, and cleaning feed distribution systems to prevent plugging. Maintenance frequency depends on material abrasiveness and operating conditions, with inspections typically recommended every 2-4 weeks.
Yes, our cone classifiers are designed to process various minerals with different density and hardness characteristics. They effectively handle metallic ores (gold, copper, iron), non-metallic minerals, and industrial minerals. The adjustable operating parameters allow customization according to specific material properties.
While both separate particles based on settling principles, cone classifiers operate at lower velocities and pressures than hydrocyclones, making them suitable for more fragile materials and coarser separations. Cone classifiers typically have larger residence times, more consistent underflow densities, and are less prone to wear, while hydrocyclones offer higher throughput rates and finer separation points.
Discharge concentration directly impacts classification efficiency. Higher concentrations (50-60%) typically result in sharper separations but may increase the risk of coarse particles reporting to overflow. Lower concentrations (40-50%) provide more dilute underflow with potentially higher recovery of fines but may compromise separation sharpness. Optimal concentration depends on the desired cut point and material characteristics.
