List Types of Pumps. The pumps in a mineral processing concentrator (plant) can roughly be classified into two groups, PROCESS pumps and SERVICE pumps. A service pump is any pump that provides a service to the process. A Process pump is one whose function is part of the process.
Comminution and classification technologies of iron ore. Aleksandar Jankovic, in Iron Ore (Second Edition), 2022. 8.3.3.1 Hydrocyclone separators. The hydrocyclone, also referred to as cyclone, is a classifying device that utilizes centrifugal force to accelerate the settling rate of slurry particles and separate particles according to size, shape and specific gravity.
The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container. The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds …
With respect to the cyclones performance, the benefits were achieved mostly by reducing the variability of the cyclone pressure by 32–52%, the cyclone density by 50–85%, and the cyclone overflow rate by 20–92%. No plant reported a reduction of labour or an increase in safety with the use of the control system, though one operation cited ...
Recently, an industrial scale dense medium cyclone of 250 t/h capacity for coal preparation has been operated by Ingwenya mineral processing plant located at Clewer, Emalahleni, South Africa, which produces 120,000 tons per month of high-grade coal Fig. 7.
The liberation results of the ball mill circuit product, which ultimately becomes the flotation feed for downstream processing, expressed in terms of the proportion of mineral particles with 95– liberation for galena, silver minerals, sphalerite and quartz are presented in Fig. 7. The results show significant differences across the ...
Multotec Screens reduce pegging and blinding: Blinding occurs when any particles such as: dirt, minerals and other substances, stick to and bridge across your screening surface apertures. This creates a stubborn paste that blocks screening material from movement through. Pegging is the occurrence of irregular material blocked in the screen apertures, …

Large cyclones (>660 mm) use shorter cylinder lengths. Inlet Feed Designs [image 145-2-9] Cone Section. Cone angles vary from 6 ° to 90 ° 20 ° cone angle has been the standard; however, 10 ° is common for cyclones in the mineral industry. High cone angles are typically used to achieve very coarse particle size separations
