Improvement: Shallow groove, the stator lower than the impeller, large slurry circulation volume, low energy consumption; the stator is a cylinder with an elliptical hole which is conducive to the dispersion and mixing of pulp and air. Umbrella shaped dispersion cover with hole keeps the pulp surface stable.
JJF flotation machine(floatation cell) is a new type of flotation equipment advanced in China. It can be widely used in the selection of non-ferrous metals, ferrous metals and non-metallic minerals. It is suitable for rough selection and sweeping of large and medium-sized flotation plants.
Large clearance between impeller and stator, the stator is a cylinder with elliptic hole, and it is good for mixing and dispersing the gas and pulp. The height of stator is lower than the impeller, pulp circulation volume is large, and it can be reached at 2.5 times of others.
When the impeller rotates, eddy current is generated in the vertical cylinder and the draft tube. The eddy current forms a negative pressure, and the air is sucked from the intake pipe and sucked in the impeller and stator regions and through the draft tube. Mix the pulp. The slurry gas mixing flow is moved by the impeller in a tangential direction, and then converted into a radial motion by the action of the stator, and uniformly distributed in the flotation tank. The mineralized bubbles rise to the foam layer, and the unilateral or bilateral scraping is the foam product.
Introduce: LXFD-12 Mechanical Cell Flotation is employed for agitation, separation, scrubbing and cleaning of samples in labs of geological, metallurgical, building material, chemical, coal, beneficiation plant of mine, institutions of higher learning and research institutions. XFD-12 Lab Multi-cell Flotation Machine is produced by the only manufacturer designated by the former Ministry of Geology and Mineral Resources, in compliance with the Industrial standards. XFD-12 Lab Multi-cell Flotation Machine is an experimental standard flotation machine for coal dressing and is also suitable to apply in metallurgical, geological, coal, building material, chemical, environmental protection and other industries for agitating, scrubbing, separating and cleaning minor samples. The speed of the impeller can be adjusted stepless and the speed can be displayed intuitively on the flotation machine by using the frequency conversion speed of the xfd laboratory flotation machine. The speed of the impeller can be adjusted stepless and the speed can be directly displayed on the flotation machine.
The lab flotation machine is mainly composed of the base, bracket, groove, mixer, scraper, spindle, shield, motor, Flowmeter, control switch, scraper switch and so on. XFD-12 laboratory multi-cell flotation machine is suitable for the flotation of colored, black, non-metallic and coal under-35 mesh size, and can be used for flotation test of 125 ~ 3000g flotation sample. JXSC mine machinery specializes in mining machinery manufacturing for 20 years, providing customers with a series of high-quality services, such as ore composition testing, mineral processing experiment, mineral processing process design, mineral processing equipment selection and so on.

A new hybrid froth flotation machine recovers particles with a wide size range.Coarse particles are recovered in a fluidized bed.Fines and ultra-fines are recovered in a high-shear in-line contactor.Results are given for flotation of a copper ore crushed to a top size of 600m.Coarse particle recovery limited by encapsulation of valuable particles.Modelling shows significant savings in energy, easy dewatering of tails.
A new froth flotation machine has been developed, known as the NovaCell, which can recover mineral particles over a wide particle size range, from the lower limit of flotation, to an upper limit which depends on the liberation characteristics of the ore. In a single device, the collection of the fines and the coarse particles takes place in separate environments. The finest particles are contacted with bubbles in a high-shear aerator, while the coarse particles are captured by bubbles in the gentle environment in a fluidised bed.
In this paper, the flotation of a porphyry copper ore in the NovaCell is described. The head grade was 1.0% Cu, and the copper mineral was freed from encapsulation at a relatively coarse size. The initial grind size was 600m. Tests were conducted in a laboratory unit, in both batch and continuous modes, using a conventional reagent suite. The data were analysed, and rate constants were established on a size-by-size basis. The rate constants for the batch and continuous modes were consistent. They were used to predict the performance of a bank of similar cells in series. It was found that with four rougher NovaCells in series, and a cleaner circuit, it would be possible to obtain copper recoveries above 99%. Approximately 80% of the feed is rejected as coarse gangue particles from the roughers, thereby reducing the load on the secondary mills preparatory to the cleaner circuit. The savings in operating costs of grinding energy and media, are estimated to be 40% approximately.
The NovaCell delivers two tailings streams, one of which has been de-slimed in the fluidised bed. It can be drawn from the Cell at a high percent solids, and is suitable for dry stacking without further dewatering. The test program uncovered a number of interesting features relating to the distribution of copper in the feed on a size-by-size basis, and to the maximum recovery at infinite residence time as a function of particle size, which will be described.
