Characteristics of high-efficiency LWS series three-phase
centrifuge
Ingenious, unique and diversified three-phase separation structure,
the liquid separated by the high efficiency three-phase centrifuge
is discharged in two different modes, namely gravity discharging
and discharging through the built-in centripetal pump with
pressure, wherein the latter includes liquid layer fixed mode and
the online adjustable mode of heavy phase liquid layer, which is
selected according to the process conditions.
The 2 or 3-phase decanter centrifuge separates which contains
fuilds& solids, or oil, water and solids. Due to its high dry
matter, the solids can be recycled relatively easily. In addition,
the solids concentration in the waste fuilds is lower than would be
the case if nozzle separators are used in conventional process.
★ Light phase liquid layer adjustment technology (company patent
technology, patent number: 2018213324892)
The light phase liquid adjustment sheet is concealed, and the
high-efficiency LWS series three-phase centrifuge adopts patented
technology, so that adjustment can be completed without
disassembling the machine.

★ High performance wear-and corrosion-resistant cemented carbide
Because the kitchen waste slurry in the high temperature state
contains corrosive and abrasive substances like salt, glass
fragments, and sandstone, the [ZK Separation] centrifuge has a
certain degree of pertinence in the selection of wear-resistant
materials.
★ High performance stainless steel
After the high temperature hydrolysis of the kitchen waste slurry,
due to finer solid particles and 0.1-0.08 g/cm3 liquid density difference (compared with oil and water), the
centrifuge needs a separation factor of more than 3000G to achieve
the best separation effect. Model SAF2205 with high strength and
corrosion resistance is adopted to ensure the stability and service
life of the centrifuge.
★ High-dryness screw conveyor and drum structure
The dehydration of solid particles relies mainly on strong
centrifugal force, high-torque screw extrusion force (pushing
torque), and ultra-long solid particle dehydration length. The [ZK
Separation] centrifuge can generate centrifugal force exceeding
3000G, 30 ~ 50% higher than the screw pushing torque of common
centrifuges. The screw pusher torque, and the drum dehydration
length is 10 ~ 20% longer than that of common centrifuges.
★ High torque involute planetary gear differential
The ultra-high-precision torque box is based on the high-torque
involute planetary gear differential. The differentials equipped
for the [ZK Separation] centrifuge have high torque, high speed,
low heat generation and excellent heat loss. To ensure long-term,
stable operation of the centrifuge.
★ CIP washing system
The fully automatic control system is equipped with a CIP washing
system, which can effectively solve the problem that it is not
completely cleaned during the shutdown process and effectively
avoid the equipment troubles caused by artificial factors.
