Product Description
Working principle
The vacuum permanent magnet filter machine completes its work through continuous actions such as feeding, ore blowing, adsorption into cakes, dehydration, unloading, and cleaning.
The cylinder is equipped with a permanent magnetic system of strontium ferrite, and magnetic particles quickly adsorb to the surface of the filter cloth under the action of magnetic force and gravity, forming a filter cake.
Due to the upper feeding, the concentrate in the filter cake is layered according to particle size, and the coarse particles first come into contact with the filter cloth, resulting in good air permeability.
The change in magnetic polarity generates magnetic agitation, further improving the dewatering efficiency of the filter cake.
After dehydration under vacuum, the filter cake is blown off by compressed air, and the filter cloth can be reused after cleaning.
Technical Features
Efficient dehydration: The filter cake has good breathability and high dehydration efficiency. Compared with the same specification cylindrical vacuum filter, the efficiency is increased by more than three times.
Wide applicability: Suitable for materials with a specific magnetization coefficient of not less than 3000 × 10 ⁻⁶ cm ³/g, particle size of 0.15-0.8 mm, and feed concentration ≥ 60%.
Easy to operate: simple structure, low maintenance, few vulnerable parts, supports continuously variable transmission.
Application field
Mining industry: used for dewatering the slurry of strong magnetic mineral concentrates such as iron ore.
Metallurgical industry: Processing wet magnetic separation tailings dewatering and non-ferrous metal concentrate dewatering.
Chemical industry: used for non-metallic mineral purification and solid-liquid separation of certain chemical products.
Environmental protection field: Treatment of industrial wastewater and sludge dewatering.
