Technical introduction

  Horizontal screw unloadng settling centrifuge (short form is horizontal screw centrifuge) takes advantage of centrifugal settling principle to separate soliquid suspension. The solid particles equivalent diameter greater than 3um, feed concentration, volume ratio of less than or equal to 70%, liquid-solild ratio variation: 0.05g/cm no. 3 of the various suspension are suitable for using the centrifugal to separate the liquid and solid or grading particles.
  Our company produces more than 20 kinds of centrifuges such as LW-250、LW-350、LW-430、LW-450、LW-500、LW-500、LW-650、LW-720、LWnj-A-4500 ,Wnj-B-6000、LWnj-C-750 and LWnj-D-10000. According to the structure of rotor, it can be divided into current flow, counter flow, compound screw and bidirectional extrusion. According to its applications, it can be divided into concentrate, dehydration, classification and concentrating and dewatering machine. Therefore, it can be applied to chemistry, construction, mine, municipal administration, light industry, medicine making, food and environmental protection.
Our company will choose machine and makes design for customers according to real datas and real demands. Expect your visit to our company for technical communications and long-term cooperation.

Application range:

 Advantages and features:
  1、Rotary drum and other main parts are made from stainless steel;
  2、Screw conveyer adopts special anti-abrasion measures. Hard alloy protection layer or insert hard alloy resistant sheet for spray welding;
  3、Big and long diameter ratio; high rotary speed; hold many rotary drum structures with multiple angles;
  4、Can choose heavy load, large transmission ratio of the gear, epicyclic gear and hydraulic differential system;
  5、Differential rotary speed and torsion can be adjusted automatically along with materials concentration and flow rate variation;
  6、Horizontal screw unloadng settling centrifuge with BD plate can carry out concentration of active sludge, dehydration and separation of materials which are hard to be separated.

Running advantages:
  1、Taeda sludge pressing machine is a kind of equipment for sludge deep disposal. It can reduce moisture to lower than 60% one time. With up to standard emission, Taeda pressing machine can help enterprises face with various environmental inspection easily.
  2、 Whole system runs automatically. From feeeding, filtering and discharging, there is no need for manual operation.
  3、 Low disposal cost and short disposal period. Compared with common pressing machine, its disposal efficiency is 70% higher. With super high pressure design, amount of sludge modification additives is only 30% to 50% of common pressing machine. For dealing with 1-t sludge with 80% moisture, comprehensive disposal cost is reduced by 80 to 130RMB.
