As with the internal peripheral launder the froth is pushed to the launder by the froth crowder. This design, however, provides more froth surface area. The external peripheral launder does not consume cell volume, so the effective cell volume for flotation is also higher. This launder is predominantly used on smaller TankCells.

While recent literature studies have
"The first SkimAir flash flotation cell was installed in Outokumpu's Hammaslahti Copper Concentrator in 1982 to prevent overgrinding of soft sulphides in the milling circuit. Since this first installation the popularity of the flash flotation has fluctuated depending on metal market conditions and regional preferences. Units have been installed in many commodities including …

The concept of froth crowders and was developed in the early 1950s. The need for crowding froth out of a flotation cell grew along with the size of flotation machines and their cells.. The 1st froth crowder device was patented in 1956 (Fig 1 and Fig 2). What I call the crowder plate is Piece/Item # 12 on the drawings below.

Our flotation cells are cell to cell type flotation machine which always combine several sets together as roughing stage, cleaning stages, or scavenging stages. Prominer can provide SF series self-priming flotation machine and XCF/KYF series pneumatic flotation cell which are mainstream products for the recovery and upgrading of sulfide ores.
These depart from the simpler tank/mechanism combination towards design which segregates and directs flow and towards providing an external air supply for types which had been self aerating and towards the application of hydrodynamic principles to cell design, like the Delkor BQR range of flotation machines, initially the Bateman BQR Float Cells.
