LSZ1050 Vibrating Cooling Conveyor Vibrating Cooling Conveyor is an auxiliary machine of the precision preformer to avoid stickiness and deformation of the rubber blanks.The part of the machine which directly contact rubber blanks is made of stainless steel. Rubber blank travelles through vibrating method,avoid the stickiness and deformation,the long cooling stroke,max.travel stroke upto 50 meter,cool down fully and the dry effect is prominent. Operator can adjust the vibrating frequency manually,applied for the wide range of rubbr blanks. The material of machine unit is SUS304 stainless steel to avoid the corrosion, For small size rubber blanks, can be directly cooled down by wind; For the heavy weight and much heat rubber blanks, can be cooled by circulation water from external water tank to intensify the cooling effect of rubber blanks,especially with prominent effect for FKM,NBR,CR,EPDM, pelleting, bearing seals, oil seals, O-rings, rubber flakes etc. 1.This is auxiliary machine of the precision preformer to avoid stickiness and deformation of the rubber blanks,the part of the machine which directly contact rubber blanks is made of stainless steel. 2.Small floor space,saving space 3.Suitable for liquid release agent,powder release agent or derect air -cooling. 4.Applicable to FKM,NBR,CR,EPDM and other rubber compounds,and granulation,bearing seals,oil seals,O-rings,Ling strips,Flakes of various kinds of blank. 5.Reasonble design,line hidden inside,connect all the parts of the machine with an aviation plug,easy to disassembly and installation.

RS Series Ram Rubber Strainer RS ram rubber strainer can strain various rubber compound, such as such as butadiene rubber, butyl rubber, fluorine rubber and silicon rubber and strain plastic and rubber mixture. The strain accuracy is up to 200 meshes. Compared to the screw type strainer, the compound has no temperature increase and no scorch in the whole straining process; it can strain the rubber compound after adding accelerant. It is with humanized design and easy operation, and less force to open ram head, with comprehensive safety control and impressive notice to ensure better security performance.

For example: for EPDM rubber, hardness of 60 Shore, and straining mesh size#100, then the capacity will be 600kg/h. 3、High Accuracy: with the ram to force through forward,the pressure of the standard equipment is up to 20MPa, and the high pressure equipment can reach 40MPa,It is mainly used of EPDM/NBR/FKM and other common rubber material, and maximum straining accuracy is up to mesh#300. The straining accuracy can reach mesh#500 for silicon rubber.This machine has higher straining accuracy. compared with the screw machine. 4、Stabilization: The ram push forward process is not heating-up compared with the screw extrusion,It is can adding vulcanizing agent and other rubber accelerant for straining,to stop rubber scorching of thing ever happening. 5、Convenient: The barrel adopts separated structure,center extended,It is easy to clean, easy to replace the rubber, no clean dead Angle; 6、Safety: Reliable control system and interlock device ,avoiding work injury. 7、PLC and touch screen control ,can store process parameter to make it convenient for extracting at any times ,and low requirement for the operators.
