Micro Filter Press Conveyor for Feeding materials
Mirco filter press screw conveyors is made up of sheet plate,seamless pipe,welding screw flights,motor &gearbox ,gland packing and bearings .
Some basic technical data form is for a reference
Center distance between inlet &outlet
Screw diameter (mm)
Clearance between flight and casing (mm)
Center shaft (mm))
For the photo’s screw conveyor ,it is tubular pipe with spherical roller bearing with house.Use air sealing and gland packing at both ends on tubular screw conveyor .The gland packing is made up of PTFE.
During making the screw conveyor,there exist something that need be noted as below :
1.Fabrication process on welding parts
A.all welding line must be smooth.Grind the welding line be level.Fillet welding’s line is smooth,too.
B.Make downward welding as per the correct giving direction on drawings for the component on welding materials.
C.Clean the welded products.No welding slag and dirty .Remove all welding slag and dirty before making sand blasting .
D.Polish or grind the surface on the products. No obvious pits protruding.
2.Fabrication process on sheet metal parts
A.Sheet plate,like the cover parts,must use the laser machine to cutting materials.
B.Must protect the surface on sheet plate.Attach a protective film on the sheet plate,so as to ensure no obvious scratch .
C.If the product is a complete set conveyor ,must make run test before delivery and send the test report to the customers.
Choose the suitable packing materials which can be shockproof,waterproof and avoid heavy stress .Usually we have three types packing as below :
Changrong can provide customers for engineering + manufacturing +custom solution.
(1)Start up without any materials inside the conveyors .Do not feed materials into conveyors before connect the power resource.
(2)When screw conveyor starts to work,feeding material’s rate shall be increased evenly. Make sure the feeding speed is uniform.Otherwise,it is easy to cause the blocking or overloading and other problems.
(3)In order to ensure the screw conveyor will work without any remaining materials inside,the screw conveyor must stopping feeding materials before stop working.Stop the screw conveyor when all materials are discharged completely inside the conveyor.
(4)Forbidden any hard,big bulk materials dropping inside the screw conveyor.
(5)Stop the screw conveyor immediately if any abnormal working noise.
(6)Drive motor and gearbox shall be checked regularly.
