This method optimizes particle characteristics by incorporating a pre-desliming hydrocyclone, the characteristics of particles were optimized to regulate the hindered settling in suspension …
a mere 15%, the profit generated by a single 1000mm cyclone under these conditions is enough to pay for that cyclone in just more than a single shift's time (R300,000 ÷ (R132.22 ÷ 2 x 15%) = 8hrs 25min). Generating a profit in the order of R10/sec it becomes clear why it is worthwhile to ensure the cyclone is operating optimally.
The Cavex® DE cyclone minimises the amount of -200 mesh material in the underflow resulting in safer and reliable construction of dam walls. It also produces an underflow with high solids content. This makes it a suitable cyclone for tailings applications.
Vale and Weir Minerals partnered to optimise the desliming stage at Vale's Vargem Grande 2 Plant (VGR2), located near the town of Nova Lima in the state of Minas Gerais, Brazil. The average iron ore slimes losses at VGR2 corresponded to approximately 18% by weight of the total iron ore mined, totalling 1.9 million tons of iron lost every year.
Hydrocyclone Working Principle. The centre of this spiral is called the VORTEX. The purpose of the apex is to cause internal pressure for the cyclone and to create a vortex that extends all of the way to the top of the cyclone. In all hydrocyclones there are two outlets, one for the coarse material, this is the APEX, and the other for the …
For test A1, desliming of the 'as-received' sample at a cut point of 10 µm resulted in a significant loss (27 %) of fine chromite to the cyclone overflow. The sample was then subjected to flotation, sulphuric acid being added to reduce the pH to 2.5, with a rougher concentrate being cleaned in three stages in open circuit.
These tests were performed in a Rotina 380R benchtop centrifuge by subjecting existing desliming cyclone overflow to various durations of various centrifugal forces. Following successful results from the project perspective, second and third rounds of centrifuge tests were conducted. Fresh samples of existing desliming cyclone overflow …

WEBBoost your cyclones' dewatering performance with our CycloStack, which attaches to the bottom of a standard cyclone to automatically control the moisture content and …
The paper will look at some factors that could be influenced by these initiatives, namely: the effect of near dense material, the effect of cyclone spigot wear and the effect of overloading the process by focussing on the medium to coal ratio and desliming screen capacity. The efficient utilization of energy is also touched on. …
For desliming purposes, normal classification takes place in the upper portion of a cyclone; this can be thought of as the first stage of desliming. The CycloWash, located in the lower/apex section of the hydrocyclone, injects water into the cyclone, and the injection water displaces the fines-laden water in the partially thickened underflow pulp.
The cyclone consists of a short cylindrical section attached to an inverted, truncated, conical section. The apex or bottom of the conical section is called the underflow orifice. ... Current Bureau of Mines …

In this study, a new type of hydrocyclone sand washer was proposed, which connected a cylindrical and a conical-cylindrical cyclone in series to conduct desliming experiments on mud–sand samples. Compared with the existing sand washing process, this simplified process avoids the pulping process and improves the production efficiency.
