Mod. AP apron feeders are extremely sturdy and reliable machines, designed to feed primary crushers with rocky and big sized material. These machines are essentially composed of some steel aprons fixed to a very sturdy chain.
The chain and aprons advancement ensures that also the most heavy rocks are directed to the following machine mouth. Largely oversized transmission gears, oil bath sliding rollers, sliding parts interchangeable armour-plating. These feeders have been designed to withstand impact of the heavy blocks discharged in the hopper.
The capacity is adjusted by the variable - speed unit, that can be manual or electronic but in both cases without stopping the machine during the work.
Mod. AV vibrating feeders are utilised to feed secondary machines with gravelly alluvial or pre-crushed material.
These machines are composed of a tank hung over the casing by helical springs.
The material advancement is generated by the vibration of the two eccentric motor-vibrators.
The capacity can be adjusted acting on the discharge mouth or on the eccentric masses of the motor-vibrators.
Thanks to a continues feeding and a variable capacity, the machine which follows will always work at full rating.
