Gearbox for Rubber & Plastics Industry

Zonpoo supplies gearboxes for rubber and plastics industry, including crusher drive gearboxes, extruder drive gearboxes and mixer gearboxes.

Zonpoo extruder drive gearboxes have a substantial thrust bearing assembled on output shaft to counter the thrust from the extruder screw. The gears are finely ground at highest standard quality to ensure non-vibrational and smooth extrusion process. The input shaft is designed to stand belt drive loads and occasional overload from cold starts.

Zonpoo rubber mixer and mill gearboxes are designed to accept fluctuating loads and high powers. The gearbox output shafts are generally connected to the mixer by mill spindles or gear couplings. The twin output shafts are arranged to rotate opposite to each other. This type of gearbox is also used for twin screw extruders, where additional thrust assemblies are incorporated.
