Double screw extruder of china Size XJPS-75×350 /XJPS-160×400 Purpose Designed to forcibly extrude and sheet compounded rubber, plastic, synthetic resin or nonmetallic material in continuous production, it has high efficiency and is ideal for working with mixers or dispersion mixers. 1. This machine is comprised of the two main parts, i. e. the double conical-screw extruder and the two-roll sheeter. The design is compact and rational, and makes the maintenance convenient. 2. The stepless speed regulation with the AC frequency control technology or the DC speed regulation technology is used for the feeder and the sheeter so that it can meet the technological requirement of the rubber or resin sheeting line. 3. It has the welded feeding barrel of jacket type and the bored sheeting roll where cooling water or hot oil/hot water/steam can be lead through to control the temperature and meet the technological requirements for different kinds of stock. 4. The sheeter, which is installed on the rack and the slide rail on the base plate, can be moved horizontally through operation of the manual or pneumatic mechanism so that it can be separated and clutched, which facilitates replacing or cleaning the feed head. 5. The working surfaces of all parts in contact with stock are plated with hard chrome to resist abrasion and corrosion. 6. The double conical screws for feeding are of the tapered convergent type with variable pitch, which raises the extruding capacity. Meanwhile, the flat die head improves the extrusion density and planeness. 7. The electrical control system incorporating the PLC technology can provide not only individual control of single machines but also gang control of the sheeting line.
