Melt pumps come in a variety of types and sizes to fit the needs of your extrusion, compounding or polymer production process.
Benifits of the metering pump melt gear pump
1. Stabilizing the output pressure---the pressure on extruder can be reduced by 30%-50% after using melt pumps.
2. improving the product quality
3. increasing the extrusion output---reducing pressure on screw and chaning the building pressure from "screw to die" to "melt pump to die", so the screw can extrude the products with high efficiency. Mean while the back-pressure on the extruder can be adjusted, reducing the melt residence in screw cylinder, stabilizing the plasticizing process and improving the product's quality and quantity.
4. prolonging the working life---the pressure of extruder screw can be lowered after using the melt pumps, so screw wear can be reduced consumable

Concrete mixer (cement mixer) is a special truck used to transport concrete for construction; because of its shape, it is often called a snail car. These trucks are equipped with cylindrical mixing drums to carry the mixed concrete. During the transportation process, the mixing drum will always be kept rotating to ensure that the concrete carried will not set. After the concrete is transported, the inside of the mixing drum is usually washed with water to prevent the hardened concrete from taking up space and making the volume of the mixing drum less and less.
It is composed of automobile chassis, mixing drum, transmission system, water supply device, full power take-off, front and rear brackets of the mixing drum, reducer, hydraulic transmission system, feeding and discharging system, control mechanism and other parts. Due to technical bottlenecks, the domestic mixer trucks with a volume of 3m³-8m³ adopt the four major domestic products, and most of the four components with a volume above 8m³ are imported components.
Composition of mixer truck: second-class chassis, transmission system, hydraulic system, frame, mixing tank, feeding and discharging device, water supply system, control system, human ladder and other parts. The front end of the mixing tank and the reducer are connected and installed on the front of the rack, and the rear end is supported by the two supporting wheels installed on the back of the rack through the raceway.
