Cold Feed Rubber Strainer, DRL Series
Rubber extruder with gear pump for filtering contaminants from rubber compounds
A cold feed rubber strainer is a device designed to separate contaminations such as scrap iron and sawdust from your compounds. The rubber strainer utilizes a screw and gear pump system to feed the rubber in strip form at normal temperatures, then strain the compound. This filtering system is applicable for a variety of rubber compounds and is extensively utilized for the production of various rubber miscellaneous items, auto parts, seals, and oil seals.

Advantages
- Gear pumps can be operated with a single drive or dual drive system.
- Cold feed rubber strainer feed strip rubber compound at a normal temperature through a gear pump controlled strainer continuously.
- 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.
