Convection Deinking Flotation Cell

Flotation deinking paper recycling deinking waste paper previous next the pulped wastepaper was diluted in a four liter flotation cell to a consistency of 1 and conditioned for 2 minutes in the presence of the collector lionsurf 768 04 poundston of dry paper as provided by lion industries

Paper recycling is a large scale multistep process with the objective to recover the paper fibers and often other paper components such as mineral fillers and use them as a raw material to produce new paper depending on the types of paper sourced for recycling and the final application each recycling system is optimized accordingly

This is the main application of this eco paper deinking flotation cell waste paper recycling equipment production line application f eature applied to deink recycled pulp it can effectively remove the ink light impurities and stickies etc efficient flotation high consistency scum less fiber loss

Deinking machinedeinking flotation cellconvection eco deinking flotation cell the eco deinking flotation is used to remove various impurities such as ink particles plastics and paddings from waste paper is extensively applied in the waste paper recycling and paper making industries convection deinking flotation machinethe convection deinking flotation machine is widely used for deinking

Injectapump replaces the foam breaker and foam tank and guarantees stable operation even with highly variable foaming behavior and changing amounts of foam with injectapump a flotation plant can be built on one floor lowenergyflotation deinking lowenergyflotation lef is a patented lowenergy deinking flotation with minimal fiber loss

Flotation deinking is one of the steps in deinking which usually consists of dislodging ink from the fibers during repulping followed by ink separation from the suspension by flotation and washing a schematic of a flotation deinking cell is shown in fig 1 it consists of a chamber in which the pulp suspension is introduced together with air

Bubbles to the ink relative to the fibers and lowers flotation deinking efficiency and fiber yield in the spray surfactant process this indiscriminant adsorption of surfactants on fiber and ink is reduced rejects foam ink accepts pulp suspension deinked pulp air pulp surfactant figure 1 a simple flotation cell for recycled paper

Inks washing and flotation today deinking is usually performed using the flotation method flotation is a separation method which utilizes the divergent surface chemical properties of different particles pulps coming from prescreening with a consistency of 23 are diluted to a 114 flotation

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

Makc deinking based on more than three decades of innovation and expertise in advanced flotation technology the new kadant makc compact flotation cell offers maximum yield and efficiency

Between different flotation systems cells and injectors can vary considerably eg in size shape and internal design and this can give rise to variation in deinking efficiency across single cells and across the flotation system depending on the number ofcells in the systemandthe configurationused flotation deinking is based on technology

And after that sent to the flotation cell in a flotation process many flotation cells are used in serial after the flotation step the paper is bleached to give a satisfactory level and sent to a storage tower figure 1 flow sheet of deinking mill 22 optical properties of paper the quality of a flotation deinked paper is judged by its

Deinking of secondary fibers involves dislodging ink particles from fiber surfaces and separating dispersed ink from fiber suspensions by washing or flotation enzymatic approaches involve attacking either the ink or the fiber surfaces different enzymes have been used for deinking including lipases esterases pectinases hemicellulases cellulases and ligninolytic enzymes
