2.2 The gear accuracy is grade 6(Chinese standard), which is a high precision. High speed heavyduty hard-tooth-surface. The materials are 20CrNi2MoA and 20CrMnMo,carburizing heat treatment of gears HRC60-62;

2.3 Involute gear teeth couplings between the output shafts and screw shafts;

2.4 Use imported brand bearings. Integrated thrust bearing assembly is Name Luoyang.

2.5 The bearings and gears are forced to adopt the immersion oil-lubrication system. Oil pump motor power 0.75kW;

2.6 Oil seal of the body: Taiwan Hansheng brand;

2.7 Tubular condenser, cooling area of 2.6 square meters;
 


3. Screw Elements：

3.1 Kneading blocks are made by CNC machining center, same size for different batches, with good interchangeability and self-cleaning quality;

3.2 Involute gear teeth connection to ensure power flow between the screw shaft and screw elements;

3.3 Screw element diameter:71mm; L/D=52; numbers of barrels:13

3.4 Screw rotating speed: 600r/min.

3.5 Material of screw element: W6Mo5Cr4V2, Hardness: HRC60-62.
 


4. Barrel：

4.1 The barrels are made by CNC machining center,the aligning pin and inner hole are completed by machining center in one time. Inner hole is grade 6, which is a high precision. After assembly, the concentricity error is 0.05mm, thus greatly enhance the self-cleaning of screw and reduce energy consumption;

4.2 The barrels are equipped with stainless steel integral shielding which are secure, good-looking and power saving;

4.3 The barrels are produced with bimetallic alloy cover：HRC60-62;
