Duplex stainless steel 2205 sludge dewatering decanter centrifuge
machine
Description
It has a good applicability for many material and can be widely
used in chemical industry, light industry, food, paper, mining and
other industrial sectors. It applies to carry out separating liquid
and solid of the suspensions material which weight thickness of
solid phase ≤ 10% (or volume concentration of ≤ 50% after
settlement24 hours) and equivalent diameter of solid-phase particle
≥ 0.005 ~ 2 mm, liquid-solid density difference ≥ 0.05 g / cm 3,
such as calcium carbonate, calcium sulfate, polyvinyl chloride,
lees, bean dregs , soy protein, paper pulp, vegetable oil and palm
oil, kaolin, white mud, sludge from environmental protection
industry and also applies to various types of chemical products
which use settlement centrifugal separation principle, these
material all can be carried out effectively.
According to feed feature, product can be divide into LW two-phase
separator, LWS three-phase separator. It is suitable for separating
different feed under different process condition, and widely use in
pharmaceutical, food, chemical, light industry, environmental
protection industry etc.

Working principle
The suspension enters the drum through the feed pipe and the spiral
discharge port. Under the action of the centrifugal force generated
by the high-speed rotation, the solid particles with a larger
specific gravity are deposited on the inner wall of the drum, and
the spiral blades that move relative to the drum continuously move
.The solid particles deposited on the inner wall of the drum are
scraped and pushed out of the slag discharge port.The separated
clear liquid flows out of the drum through the opening of the
liquid layer regulating plate. The relative movement between the
screw and the drum, that is, the differential speed is realized by
the differential, and its size is controlled by the auxiliary
motor.
Product structure
The centrifuge is a countercurrent horizontal spiral discharge
sedimentation centrifuge for sludge dewatering. The main engine is
composed of drum (stainless steel 2205), screw (stainless steel
2205+316L) and differential system. The differential speed is
automatically fed back and adjusted according to the load change,
and the pushing power is automatically compensated to ensure the
constant dryness of the solid slag and get a drier solid slag.
It is poured by an integral centrifuge, and then processed by
precision turning after solution treatment. The solid phase slag
discharge port is equipped with replaceable tungsten carbide
wear-resistant bushing. The inner wall of the centrifuge drum is
welded with anti-skid wear-resistant strips to prevent the solid
particles from tangential rotation and wear on the inner wall of
the drum.

Advantages
1)Rotation speed of distiller's grains dewatering centrifuge:
Generally, distiller's grains dewatering centrifuge should be above
3000 revolutions. The higher the rotation speed, the higher the
separation factor of distiller's grains dewatering centrifuge, and
the better the separation effect.
2)Material of distiller's grains dehydration centrifuges: Different
materials have different physical and chemical indicators such as
wear resistance and corrosion resistance. Foreign distiller's
grains dehydration centrifuges are generally made of 304L or duplex
stainless steel, and the abrasion components must be made of
ceramic composite materials.
3)Differential control of distiller's grains dehydration centrifuges:
Different differentials have different control accuracy, and there
is a significant difference in service life and maintenance costs.
The higher the differential accuracy, the better the adaptability
to materials. Therefore, it is advisable to select equipment with
high differential accuracy.
4)Length to diameter ratio: The larger the length to diameter ratio
of the distiller's grains dehydration centrifuge, the greater its
processing capacity, and the lower its moisture content.
5)Control system: Whether it is automatic programming control.
Currently, domestic and foreign equipment manufacturers have
basically achieved full automatic control of the equipment.
6)Installation power: It affects the control of energy consumption.
Generally, domestic equipment has a high energy consumption ratio,
while foreign equipment has a low energy consumption ratio.
7)Processing and manufacturing technology: The distiller's grains
dehydration centrifuge is a separation equipment with high
precision processing requirements. Enterprises that do not have
precision processing capabilities produce products with high
maintenance rates and limited processing capabilities.
