Structural features of extruder for vacuum sizing production line:
The extruder implements the JB / T8061—1996 standard (national standard) according to the machinery industry standard. The structure is separated (BM type) and has a two-stage structure with a mixing section. The feeding section has a special forced-feed groove, screw and screw. The cylinder (Zhoushan, Zhejiang) is the key part of the entire extrusion system. All are made of high-quality alloy steel 38CrMOALA after strict heat treatment and fine processing. The surface is nitrided. The nitridation depth is 0.6-0.7mm, and the brittleness is not greater than 2 High strength, wear resistance, corrosion resistance, good screw plasticizing effect; temperature control system uses ceramic heating ring heating and fan cooling, temperature sensor, temperature controller, etc. for automatic temperature control; special type of hardened tooth surface of reducer structure, With oil pump forced lubrication system and forced cooling system, high torque, low noise and long service life.
