In the field of quartz beneficiation, the traditional gravity separation process often faces technical bottlenecks such as large fluctuation in recovery rate, high energy consumption and cost, and loss of fine-grained minerals. As a global leading mineral processing solution provider, Xinhai has constructed an intelligent quartz classification system by integrating six core gravity separation equipments to help customers realize a double breakthrough in beneficiation efficiency and economic benefits.
1. Pulse jigger unit
Adopting digitalized water flow control system, it realizes pulsation frequency adjustment with 0.01 second precision, which is especially suitable for primary enrichment of quartz sand of 3-25mm grain size. The bed status is monitored in real time by dynamic pressure sensors to ensure that the processing capacity is stabilized in the range of 150-300t/h.
2. Spiral chute
Chute is a simple gravity separation equipment, through the flow of slurry on the sloping surface, using the density difference of mineral particles for separation. The chute is suitable for processing coarse-grained ores, simple to operate and easy to maintain.
Xinhai spiral chute adopts the innovative design of corrugated plate + wedge bar composite trough surface, which improves the separation efficiency of coarse-grained quartz by 40%. Equipped with automatic flushing device to solve the downtime problem of manual slag clearing in traditional chute.
3. Three-dimensional dynamic shaking table
Shaking table is a kind of equipment that utilizes the asymmetric reciprocating motion of the bed surface and the action of inclined water flow to separate the ore particles according to the density and particle size. Shaking table is suitable for processing fine-grained ores, and can obtain high-grade concentrate.
Three-dimensional dynamic shaking table through XYZ three-axis linkage technology to strengthen the dispersion of mineral particles layering, 0.074-2mm fine grains of quartz can reach more than 92% of the sorting accuracy. Equipped with machine vision system to monitor the distribution of concentrate zone in real time.
4. Modular Drum Sorting Machine
Patented design of replaceable polyurethane liner, combined with frequency conversion speed control system (0-15rpm stepless adjustment), to realize the accurate matching of processing capacity and sorting particle size, and reduce the footprint of the equipment by 35%.
5. Double Screw Vortex Classifier
Double spiral structure made of 304L stainless steel shows excellent performance in quartz-feldspar separation. The unique secondary water curtain system can increase the recovery rate of -0.5mm micro-fine grains to more than 85%.
6. Intelligent Centrifugal Concentrator
Integrated centrifuge technology, through the G value adaptive control system (20-300G adjustable), the quartz concentrate grade is stabilized at over 99.5%. Equipped with automatic ore unloading device to realize continuous production.
1.Efficiency revolution: centrifugal unit is combined with traditional equipment to increase the comprehensive recovery rate by 15-30%.
2.Energy consumption optimization: Intelligent frequency conversion technology reduces the power consumption of ton processing by 0.8-1.2kWh.
3.Process Flexibility: Supports the processing of quartz sand, quartzite, vein quartz and other raw materials.
4.Intelligent control: SCADA system realizes cooperative operation and remote diagnosis of equipment groups.
From laboratory re-election tests to industrial-scale system design, we provide:
- Mineral selectivity studies and process simulation
