400 Tons/Day Lithium Ore Processing Project

For a lithium ore processing plant with a daily processing capacity of 400 tons, equipment selection should prioritize high efficiency, energy saving, and system integration, especially in the dewatering stage, which significantly impacts capacity matching and operating costs. Based on existing industrial practices, for a scale of 400 tons of lithium ore per day, a vacuum belt filter is recommended as the core dewatering equipment, offering superior efficiency and cost control compared to traditional filter presses.

In the lithium ore beneficiation process, dehydration is one of the key steps, directly affecting the quality of concentrate products such as lepidolite and subsequent processing costs. For medium-sized lithium mines with a daily processing capacity of 400 tons, the selection of efficient continuous dehydration equipment is particularly necessary.

• Equipment advantages:

  • Employing an optimized vacuum system, the Li₂O content of dehydrated lepidolite can reach 68%, a 15% improvement over the industry average.
  • Continuous operation mode is suitable for a stable production capacity of 400 tons/day, avoiding the energy waste caused by frequent start-ups and shutdowns of intermittent filter presses.
  • Compared to traditional filter presses, the number of machines can be reduced from 8 to 3, the floor space is reduced by 60%, and annual maintenance costs are reduced by 450,000 yuan.
  • The filter cloth has a lifespan of over 12 months, is made of high-strength polyester material, has strong corrosion resistance, and is suitable for lithium ore slurry environments.

• Applicable scenarios:

  • Dewatering of lithium concentrate after flotation;
  • Preliminary solid-liquid separation of tailings;
  • Forming a closed-loop system with ball mills and classifiers to achieve full-process automation.
