75L kneader

75L kneader

１. operating principle and structure characteristics：

The operating principle of this machine is the same as the ordinary mixer. The pressure lead to the material, the two rotors move in the different speed ratio in the airtight groove, with of shear, extrusion, mixing, folding volume etc. After kneading function, plastic (mixed) refined into needing raw material.

２ mixing device

Mixing chamber , left and right side plate forms a closed slot, front and rear rotor bearing using the centripetal spherical roller bearing, through bearing sleeve which separately fixed at the left and right of the side plate.

Left and right side plate are both with the cooling (heating) cavity Jacketed structure, contact with the material of the intine proceed hardening (hard chromium plating) processing, thickness 0.1~0.15mm，hardness HV900~1000.

Rotor of the long and short two spiral welded edges on the rotor shaft, site edge and working edge peak side surface, the rotor seals surfacing both are welding carbide wear-resisting, its hardness is 50 HRC, thickness is 5 mm. Contact with the material of the rotor surface hardening (hard chromium plating)processing, the thickness of 0.1 ~ 0.15 mm, its hardness is HV900 ~ 1000.

Rotor end face seal by pressing sleeve ring seals top on the surface sealing of rotor. Sealing ring is made up of high temperature resistant, wear resistant, small expansion coefficient of bronze and teflon material. Friction work head face don’t need oil lubrication, so can guarantee a good sealing effect and no pollution material.

3.drive system

Main drive by a belt drive, drive gear reducer, gear reducer output shaft through the internal-gear sleeve coupling drive ratio gear rotor realizet before and rear rotor relative rotary

movement.

 ４.Flip device and Drive system

Tilt Motor(electromagnetic brake:the three-phase asynchronous motor) through the cycloidal reducer drive worm, worm gear make the whole mixer device along before rotor axis as as the center (forward) to realize the reverse discharging. Mixing chamber device turn 140 ° after unloading, recovery. Mixer chamber flip by limit switch limit, high

accuracy, good durability.

５. Swage setting device、dust keeper and air control system

Pressure lead driven by cylinder pressure.Swage setting device’s pressure device under the impetus of the cylinder pressure was carried out on the material. Pressure lead use jacketed welding structure internal cooled water and material contact surface hardening treatment. Pressure lead is equipped with sealing strip around, prevent the mixing process of powder leaked. Pressure of cylinder at the top of the rack installation, operation process by limit switch limit.

６Electrical heating system

ThE machine has a cooling pipe system. Due to the machine and material contact parts both are jacketed welding structure, the inlet and outlet piping both have cut-off valve, so can ensure efficient cooling effect.

７. Electrical section outlines

Electrical part adopts Germany Omron Company’s programmable controller as the main controller, the main electric elements adopt

domestic excellent products, make the whole electrical part function

is advanced, convenient operation, safe and reliable.
