MDS411 Screw Press Machine Introduction
MDS411 screw press machine comparing with the traditional belt, plate& frame and centrifugal machine,volute sludge dewatering machine adopts integrated design of dehydration ontology, flocculation mixing tank and electric control device, convenient installation , small area cover, strong compatibility with ancillary equipment, greatly reduce design and the construction cost, at the same time, no need to undertake civil construction as its exquisite design.

MDS411 Screw Press Machine Structure Principle

Dewatering: The thickened sludge moves forward continuously from the thickening zone towards the dewatering zone. With the  pitch of the screw shaft thread getting narrower and narrower, the pressure in the filter chamber increases higher and higher. In addition to the pressure generated by the back-pressure plate,  the sludge is greatly pressed and dryer sludge cakes produce.

MDS411 Screw Press Machine Details
Name: Over All Unit
Materials: SUS304
The over all unit is made up of SUS304 material, with smooth surface. Laser cutting technical ensures the evenness of machine surface.

Name: Rings
Materials: SUS304
First of all, mechanical shaping is done to the rings by imported processing equipment from Switzerland. Then manual shaping is done to control the deviation of evenness under 0.01mm.
 

Name: Screw Shaft
Materials: SUS304
Tungsten carbide coating are done to the screw shaft surface. The hardness can reach HRC 71. The blade of screw shaft also get chamfering process treatment, to match with the ring.

Name: Spray Tube and Nozzle
Materials: SUS304
Spray tube uses SS304 steel, mirror polished.
Its nozzles can achieve well-distributed spray, can achieve solid cone effect,which is better than stainless steel nozzle suppliers

MDS411 Screw Press Machine FAQ

Solenoid Valve
We use ASCO solenoid valve, the famous American solenoid valve manufacturer as the solenoid valve is easily break down, owing to repeatedly open and close ,so we choose the solenoid valve with best quality, but the price is 30 times of ordinary solenoid valve.

UPVC Tube
The UPVC tube is a kind of high intensive tube,can be resistant to 16kg pressure. It branded Youli Shanghai, the best domestic tube brand.

Cables
We use Far East cable, famous brand in China
