The second plant, which is designed to deal with open ore-poor ore, was originally designed as a process of grinding and returning to the mine. Because the ore selection plant of the ore was originally designed as a section of grinding, the process of returning to the middle mine. Due to the serious secondary alteration of the ore body, the output of coarse, medium, fine-grained structure and various types of ore with different alteration strengths is obvious, and it is difficult to select, the index is low, and the average recovery rate is only nickel 55. %, copper is about 45%. The original design ore was ground to 65-70%-0.074 mm at a time, which not only allowed 45-50% of nickel-copper to be distributed to -0.04 mm. Moreover, a large amount of slime such as serpentine, chlorite, talc , carbonate, etc. contaminates the surface of the sulfide and consumes chemicals. After changing to the two-stage grinding process, the fineness of the first and second stages of grinding was 55% and 70%-0.074 mm, respectively, and the concentration of one stage of flotation was reduced to 28%. In the second section, 24%, the recovery rate of nickel increased by about 5%. After reducing the flotation concentration, increase the number of flotation tanks appropriately to ensure that the flotation time is above 55 minutes. The efficiency of the flotation machine is also improved by increasing the spindle speed and increasing the amount. The use of butylammonium black instead of butyl xanthate, without the use of the activator copper sulfate, does not reduce the flotation index. At present, sodium carbonate, ethyl xanthate and butylammonium black are banned, and the dosage is lower than the original. Through the above measures, the recovery rate of nickel can be stabilized at 89-90%, and the recovery rate of copper is 82-85%. Recovery CONCENTRATES PGE correspondingly improved, more platinum, palladium recovering rate of 80%, 3-4-fold enrichment ratio, rhodium, iridium. Osmium, ruthenium recycled nearly 70%.
Working principle:
Horizontal Ribbon Blender consist of U-shaped barrel, agitator, speed reducer and electric motor .Untwist double ribbon are swirled with the main shaft in the U shape barrel. The outer ribbon push the material from the two ends to the center of the barrel, inner ribbon push the material from center to the two ends. Thus to achieve material convention
Under the driven of motor, the double ribbon agitator mix the material quickly. This ribbon blender is characterized by high mixing effect, large productivity, and a very low failure rate. Since it is a batch type mixer, customer should choose the model according to the output per batch.
The discharging port is set in the bottom center, with the help of the outer ribbon,the material can be discharged completely, and no dead zone.
We also provide suitable feeding machine for the ribbon blender,such as Screw Conveyor, Vacuum Conveyor,Bucket Elevator,flexible screw conveyor etc.
Application:
The horizontal ribbon blender is widely used in chemical, pharmaceuticals, food, and construction line. It can be used to mix powder with powder, powder with liquid, and powder with granule.
