Rubber Internal Mixer (X(S)N-75L) , Internal Mixer
Brief Introduction:
1.    Mixing Chamber
The mixing chamber is mainly made by alloy steel with harden treatment. The surface of internal chamber is with anti-wear alloy metal built up welding and plated with durable and anti-corrosion hard chrome.
2.    Regular Note Pump
Timing injection pump to the sealing system on a regular injection of hydraulic oil, lubrication sealing effect.
3.    Thermal Resistance (or thermal couple)
There is a plug-in thermal resistance or thermal couple in middle section of the bottom of the chamber to be connected to electrical system to inspect and control the mixing temperature.
4.    Rotors
It is designed to the hollow blades of banbury type. The hollows are connected with axial hole of rotor shaft used as cooling or heating passage. The top edges and the side faces of blades are surface welded with hard alloy, then plated with hard chrome and polished.
5.    Cooling/heating System
A common piping system is adopted for either cooling or heating material in mixing operation. Through the system cooling water or steam is fed in three ways to the cavities of the rotors blades, - the jackets of the mixing chamber and the top ram.
6.    Tilting Mechanism
It consists of a rotor with brake, cycloidal gear reducer, TP type worm and worm gear, etc. It is able to actuate the mixing chamber tilting by 140° around the front rotors.
7.    Dust Stop Device
At the joint between the top of mixing chamber and the cantilevered arm of the machine frame, the dust sealing assembled with curved slotted partings are used for obtaining an excellent and reliable sealing purpose. The end face of the rotor is sealed by end contact sealing with non oil-lubrication and it seals well and is wear-resistance and durable.
8.    The transmission system
The transmission system adopts harden-gear speed reducer with a compacted structure for lower noise, longer product life and increased safety factor.
9.    Pneumatic control system
Pneumatic control system is controlled by PLC order. A bi-directional air cylinder makes the ram up or down. In case of the over load occurs when mixing chamber, the top ram can be raised automatically or manually if necessary, so as to protect motor from overloading.
10.  Electrical Control System
Imported PLC device and electric control components which are all imported products or imported technology products are adopted in the electric control system to raise control reliability.
