Summary
NHZ-3000L vacuum kneader is the main equipment for production of high temperature mixing rubber.
We combined the advantages of domestic kneading stirrers, designed unique helix angle to produce strong friction and shearing force during kneading; the domestic initial creation of shaft center hole passing cooling water and advanced jacket heating structure enable fast temperature rise and fall within a short period, with optimal effects of even dispersion, etc. This machine fills many technical blanks of the country. The vacuum box type shaft sealing structure（national patent No. ZL200420087991.3）fundamentally solves the problem of black sealant leakage and shaft vacuum leakage.
The control system of this equipment adopts PLC control, with computer monitoring. The computer can randomly set material temperature, vacuum pressure, nitrogen flow, machine running speed and time, etc., and can monitor the power and torque of the machine at working. The system has automatic, manual and emergency control modes. When communication of computer at failure, you can change to manual or emergency control. The special software matching with machine can realize fully automatic control and intelligent control of the kneading process, and implement real-time analysis of power and temparature curves, which is particularly useful for customers to optimize technical conditions, to improve quality of products and increase production efficiency, to reduce time and save energy and reduce cost.
Features of NHZ-3000L Vacuum Kneader
1. Enhanced stirrers with main transmission parts from world-famous brands, such as Taiwan Tatung motor, Japanese Sumitomo decelerator, Mitsubishi frequency inverter, Siemens PLC control system, Advantech industrial control computer, and SIEMENS or Shanghai SCHNEIDER low voltage electric components, etc., which greatly improves overall system reliability.
2. Shaft sealing position adopts special treatment to increase hardness of sealing position, make sealing position more wear-resistance, ensure shaft sealing performance and increase the use life of machine.
