Lwz Spiral Decanter Disc Combined Centrifuge

Product Description

LW ZHorizontal Decanter Centrifuges

LWZ application:

It is widely used in solid-liquid separation, dehydration,clarification and classification of suspension in chemical industry, light industry, environmental protection, pharmaceutical, food, oil mining and other industries.

LWZ Characteristic

1. Wide scope of application: For suspensions with solid mass content≤ 50%, liquid-solid volume concentration ≤ 75%, liquid-solid weight difference ≥0.05g/cm3, the equivalent diameter of solid particles ≥ 5μm can generally be separated, dehydrated, clarified and classified. When the difference between solid phase and liquid phase is large, the equivalent diameter of solid particles (≥2μm) can also be separated.

2.High degree of automation: the machine is continuous feeding, continuous discharging. Under the action of centrifugal force, solid particles are continuously pushed to the small end of the drum by helix, and the clarified liquid is continuously discharged from the large end overflow port along the spiral groove, thus realizing continuous automatic operation.

3.The machine has compact structure, small floor area and convenient installation and maintenance.

4.Convenient adjustment: The machine is equipped with advanced frequency converter. As a result, when compared with similar products, the machine has the advantages of low energy consumption and stepless adjustable working speed. The diameter of overflow plate and differential speed can be adjusted according to material properties.

Advantage

1. this liquid clarifying device adopts horizontal design which balances the layout of electric motor and bowl. As a result, outstanding operation stability generates minimized vibration.

2. Dual eletric motor control enables stepless speed adjustment on bowl and spiral components.

3. Scroll conveyor flight inside this continuous centrifuge is painted by abrasion resistant alloy or welded by hard alloy. Moreover, main components on our horizontal decanter centrifuge, such as rotating bowl and spiral parts, are made from corrosion resistant stainless steel or dual-phase steel, whereby offering exceptional speed limits and separation ratio.

4. Our mud dewatering equipment comes with three options including cycloidal gear, planetary gear and hydraulic differential, resulting in large rang of differential adjustment. Therefore, this industrial centrifuge can be applible to diverse solids.

5. Multipe protections are available on our horizontal decanter centrifuge to ensure operation safety, including over-vibratation protection, bearing temperature detection, screw conveyor torque protection rotating and differential speed detection, as well as nitrogen-filled explosion-proof protection, motr overload and over heat protection.

6. JG type rubber shock absorber requires no anchor bolts.

Main characteristics

1. Continuous working, spiral discharging, high capacity

2. Compact structure and easy maintenance.

3. Wide applicability for chemical, oil, foodstuff, pharmacy industries and green industry in which solid-liquid separation is required.

4. Suitable for various products, capable for separating wide-ranging solid phase grains(0.005-2mm),especially when separating solid phase has different size grains.

Main Choices

According to user's requirement, the product contact parts can be made of austenite stainless(321,316L….),Haynes alloy, titanic alloy or other anti-erosion materials.

All machine parts touch with materials are stainless steel (SUS304) made, to ensure the machine corrosion- resistant and durable.
