New pusher centrifuge with multiple functions

The new pro­ducte of the com­pa­ny ANDRITZ has only one motor for both func­tions, thus sig­nif­i­cant­ly reduc­ing installed pow­er and pow­er con­sump­tion. Push­er cen­trifuges with two motors gen­er­al­ly only require the full pow­er of the dri­ve motor dur­ing the start-up process, and the dri­ve motor usu­al­ly oper­ates at par­tial load dur­ing steady state oper­a­tion. Con­verse­ly, the push­er motor runs at vir­tu­al­ly no load dur­ing machine start-up because there are no solids in the machine yet to be pushed. Hence, the push­er motor does not oper­ate under load until sta­tion­ary oper­a­tion begins.
 
There­fore, it allows the reserve capac­i­ty avail­able for push­ing to be used for accel­er­at­ing the bas­ket dur­ing the start-up process, while the reserve capac­i­ty avail­able for the start-up process can be used for push­ing dur­ing sta­tion­ary oper­a­tion. This results in sig­nif­i­cant­ly low­er installed pow­er and a motor that oper­ates in the opti­mum effi­cien­cy range at all times. Total pow­er con­sump­tion is there­by reduced by around 10 to 20%, while the installed pow­er is reduced by around 20–40%. Fur­ther­more, the new high-pres­sure push­ing sys­tem cuts hydraulic flu­id use by up to 40%.
 
The new push­er fea­tures inno­v­a­tive tech­nolo­gies such as the Gen­tle­Feed­er^TM wear-reduc­ing feed sys­tem, the Pre­Filtra­tion tech­nol­o­gy for inte­grat­ed thick­en­ing as well as the unique car­tridge tech­nol­o­gy to reduce down­time. With this sys­tem, the entire rotat­ing unit can be pulled out of the cen­trifuge in one piece with­out hav­ing to detach the machine’s pipework, with the result that oper­a­tions are gen­er­al­ly down for less than a sin­gle shift. What’s more, the bas­kets in an ecoOne push­er cen­trifuge are designed so that the cen­trifuge can eas­i­ly be con­vert­ed from two-stage to three-stage design and vice ver­sa. This gives the cen­trifuge unri­valled flex­i­bil­i­ty because the design can be adjust­ed as upstream require­ments change or if the cen­trifuge is used for cam­paign-based operations.
 
Suit­able for bulk chem­i­cals, tech­ni­cal salts and agro­chem­i­cals as well as plas­tics pro­duc­tion, the lat­est inno­va­tion of the com­pa­ny retains the reli­a­bil­i­ty and wash­ing effi­cien­cy of tra­di­tion­al push­er cen­trifuge tech­nol­o­gy while increas­ing ener­gy effi­cien­cy, flex­i­bil­i­ty, and ease of main­te­nance, there­by reduc­ing oper­at­ing costs and down­time. In addi­tion, the weight of the ecoOne push­er cen­trifuge is sig­nif­i­cant­ly low­er and its space require­ment and envi­ron­men­tal foot­print are sub­stan­tial­ly small­er than those of pre­vi­ous generations.
