Rubber extruder with gear pump for filtering contaminants from rubber compounds

The hot feed rubber strainer is a machine specially designed to remove contamination, such as iron scrap and sawdust, from rubber. This equipment works by feeding the material in the form of balls or strips into a screw and gear pump, then into the strainer. Not only rubber compounds, but it is also suitable for filtering a variety of products, including miscellaneous rubber parts, seals, vehicle components, oil seals, and more. Due to its versatility and efficacy, this type of filter is widely used in manufacturing processes for the previously mentioned products.

Advantages
  • Gear pumps can be operated with a single drive or dual drive system.
  • The hot feed rubber strainer is utilized to cut the normal temperature strip rubber compound into the customer's desired shape and weight continuously. The weight accuracy of the rubber blank is monitored to within ±1% via the control of a gear pump.
  • Quick product setup with PLC control and process parameters database.
  • A separation structure using an electric motor supports the gear pump, screw and machine head, simplifying rubber raw material replacement and conducting easier cleaning.
  • Low temperature increase prevents scorching. Sulfur can be utilized optionally to avoid any potential risks.
  • Error alarm with an icon displaying fault location.
  • The searchlight is a useful tool for cleaning, helping to ensure that all those tricky, hard to reach spots don't get overlooked.
  • Both system and extrusion pressures are intuitively displayed on the touch screen.
  • When creating a prototype of a new product, having a PLC in operation provides useful data that can be used to streamline the process.
