hopper is pumped to cyclone cluster # 1. In the same way, the SAG Mill # 2 (5.55 m Ø x 7.3 m EGL, 3750 KW motor) and Ball Mill # 2, have a dedicated discharge hopper, pumps and cyclones (cyclone cluster # 2). The cyclone overflow from each cluster reports to respective trash screens and underflows to respective distributor boxes.
Discloses apparatus to perform a process to remove water and minerals from a bitumen froth output of a oil sands hot water extraction process. A bitumen froth feed stream is diluted with a solvent and supplied to a primary inclined plate separator stage, which separates the bitumen into an overflow stream providing a bitumen product output from the circuit and a bitumen depleted underflow stream.

the bypass of coarse particles to the overflow of the secondary cyclone is minimised. An added benefit of this reduced turbulence (and its associated pressure drop), is that the Cavex® DE cyclone can be operated at similar pressure drops to conventional cyclones.

the cyclone diameter. The cylindrical section is the next basic part of the cyclone and is located between the feed chamber and the conical section. It is the same diameter as the feed chamber and its function is to lengthen the cyclone and increase the retention time. For the basic cyclone, its length should be of the cyclone diameter.
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 result, essentially, is a second stage of classification taking place, where the displaced water with fines joins the normal cyclone overflow.

The overflow of the cyclone, where majority of the fine particles will be reporting is then pumped to the rejects tank while the underflow will be fed to the primary Wet High Intensity Magnetic Separator (WHIMS). The non-magnetic materials from the primary WHIMS will be reprocessed in the secondary WHIMS to maximize recovery.

The DL cyclone secondary shutoffs and moisture trap are designed to be installed in correspondence with the intake line of decompressors used to create vacuum inside tanks.The cyclone secondary shutoff and moisture trap prevents foreign bodies (liquids or solids) that could carry over past the primary shutoff from entering inside the decompressor by blocking the intake line with a stainless ...
A research program was performed to examine new technology for clay removal from Florida phosphate ore. One aspect of the research tested four applications of ultrasonic treatment: 1. Sonication of pebble to remove mud balls 2. Sonication to clean the surface of flotation feed 3. Sonication to remove reagents from rougher concentrate 4.

The lighter particles are caught in an upward stream and pass out as clean coal through the cyclone overflow outlet via the vortex finder. From the overflow orifice, the coal goes into the overflow chamber, and is discharged to the next stage of the process. Fluid on entry commences in the outer regions of the cyclone .
