SIMEX twin header rotary cutters offer significant increase in yield and reduction in waste for mining and quarrying operators. Where the traditional  ‘drilling and blasting’ method used to quarry on fractured rock can be a time- consuming two-stage process, SIMEX twin header rotary cutters give excellent results when conventional digging systems are too weak and percussion tools have little effect.

Simex twin headers are designed to be used in quarrying, tunnelling and mining applications with a variety of rock including limestone, gypsum or schist of hardness of up to 85 mPa.

SIMEX’s patented design ensures minimal vibration, low noise and high torque featuring 90 degrees cutter head rotation and a sealing system that prevents impurities entering the motor even when the attachment is submerged into the ground or operating in muddy conditions.

Replaceable anti-wear plates reduce maintenance costs, and double support bearings for each drum ensure longer service life as shaft transmits motion only and bears no load.

SIMEX twin headers can be mounted on carriers from 1.2 tonnes up to 70 tonnes with maximum cutting force varying from 13.5 to 114.5 kN.
