4+4 Hp manual double grinding machine has a strong metallic carpentry base with an integrated electrical panel housing two user interface panels. Each of them is composed of a potentiometer to set the brush speed rotation, a rotations number digital display, an emergency and a startup button.
The two brush spindles are assembled on strong bearings, with trapezoidal belts connecting them to the two independent 4Hp three-phase asynchronous motors.
The pneumatic belt tighteners allow a 3500mm maximum belt length, with the possibility to add a third wheel working on a free belt.
The two high-performance inverters allow an adjustment from 600 to 2800 rpm of the brush rotation speed.
The protection housings, which are optional but mandatory, are galvanized or painted. They are predisposed with a connection to a suction plant (the vent measures Ø120 mm) and with a dust recovery drawer.
