flotation cells for recycling

Highturbulence flotation cells was used for plastics flotation in certain cases Sisson 1993 Hwang 1995 Kobler 1995 In most of these applications the separation was carried out on flakeshaped particles less than about 12 mm in size having a thickness less than 075 mm

The MAC flotation cell was developed by KadantLamort Inc It can save energy compared to conventional flotation systems The MAC flotation cell is mainly used in the flotation section of waste paper deinking pulping for removal of hydrophobic impurities such as filler ash ink particles etc

Some key limitations to the installation of conventional flotation cells in the OCC recycling process are high flotation losses and large floor space requirement These restrictions are largely overcome by the use of flotation columns which differ from conventional cells by their greater heighttodiameter ratios lack of mechanical

RCS Flotation machines The RCS flotation machine combines the benefits of circular cells with the unique features of the DV mechanism creating the ideal conditions to maximize flotation The new improved RCS flotation cell is an all purpose flotation machine suitable for all flotation applications as roughing cleaning and scavenging

Flotation Cells Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic This is used in several processing industries Historically this was first used in the mining industry Froth flotation improved the recovery of valuable minerals such as copper

FoamEx mechanical destruction of foam especially flotation foam The foam generated in flotation deinking is collected and discharged into the foam tank FoamEx sits on top of the foam tank and destroys foam by creating a partial vacuum through the rotation of the conically shaped rotor The liquefied foam which is heavily loaded with ink and dirt is discharged at the top of the cone

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic This is used in mineral processing paper recycling and wastewater treatment industries Historically this was first used in the mining industry where it was one of the great enabling technologies of the 20th century

Flotation Deinking For many recycled paper qualities a much more stringent requirement on the deinkability is necessary to attain the target properties The deinkability requirements for the paper for recycling concerning optical properties is dependant on the target paper properties and the process capabilities of the deinking plant

Flotation of Copper Ores It is diagrammatic to the extent that the thickener and regrinding unit may receive its feed from several roughing machines and deliver its discharge to a number of cleaning cells It is usual to dewater the rougher concentrate and return the water to the primary circuit for two reasons

Flotation deinking is a key unit operation in most paper recycling plants for the removal of hydrophobic contaminants from pulp 12 There is a wide variety of flotation cells available for deinking but the dominant technology typically consists of multiple horizontal flotation cells in series with each cell being aerated by several injectors

The flotation cell is operated at about one percent consistency using a surfactant to help create bubbles Air is pumped into the center of the cell creating bubbles Ink particles attach to the bubbles and together float to the surface of the cell The cell contains paddles that remove the resulting foam

The hypo baric cell flotation cell is an installation with a depression two novelty elements ie a hypo baric static cell and a hydroaerator special device which realize the necessary depression above the water level and on the other hand enriching the recycling water with air

Flotation deinking is a complex process A better understanding of its fundamentals would help in developing models that can predict whether a given process change would help or hinder flotation

The clean PET and PVC mixture was conditioned in a solution of 45 gt gelatine and floated in a short column flotation cell in an upward flow of water In a single flotation step over 75 of the PET was recovered as a high purity product containing 998 PET

Too high a flow rate through a flotation cell generates large turbulent forces which can detach inks from bubbles It also can disturb the foam The required production rate sets a minimum value on the flow rate

flotation and centrifugal cleaners is required UV inks when utilized at 100 furnish level and conventional inks with waterbased coatings also require dispersion 4 For recycling into fine paper grades most ink and coating combinations require dispersion to further break down the ink specks and subsequent flotation to remove them

The present invention generally relates to a froth flotation deinking process for use in paper recycling More particularly the present invention pertains to a process for the froth flotation separation of paper and wood fibers from ash fillers printed inks and other contaminants during wastepaper recycling

The present work describes three processes ie 1 air tabling 2 triboelectric separation and 3 combination of sinkfloat separation and froth flotation for separating plastics as well as a general guideline for choosing the most effective methods when sorting a certain type of plastic mixture

ANDRITZ has developed a new multiinjector design for the primary stage in deinking flotation systems The multiinjector is tailormade for effective ink removal and consumes 50 less energy than previous designs The new design optimizes the air intake in the injector as well as the distribution within the flotation cell
