Push-pull feeders, mod. ACP, are used for primary feedings of gravelly alluvial or mountain quarry material even if large size are involved.
These sturdy constructed machines are intended for heavy duty use.

They are essentially composed of a frame on which the feeding carriege is supported by means of steel wheels, which alternatively slides backwards and forwards causing the material to move forward. The alternative strake of the carriage is adjustable and given by a connecting rod-crank system driven by a motor-reducer unit.

Vibrating grizzly feeders, mod. AVC, are used in primary rock quarry installations where the material is of large dimension mixed with a high percentage of fine parts.

The machine is particularly suitable for dry materials or in any case with negligible percentages of moisture. Mainly made up of a rectangular casing, of which the bottom is sealed, for about half of its length, by thick wearing plates, while in the remaining part some bars are mounted forming a grizzly that allows to select the material removing earth and fine parts which otherwise could overfeed the crushing machine. The support of the vibrating frame is realized on helical springs. A vibrating unit placed under the casing gives the oscillations to the machine. The amplitude of the oscillations, therefore the capacity, can be adjusted.

Apron feeders, mod. AP, are sturdy and reliable machines designed to feed big primary crushers with rocky, as well as big sized material. Mainly made up of a carrying frame and an articulated conveyor consisting of sturdy aprons. The advancement of the articulated conveyor, or track, ensures that even the biggest blocks are introduced to the crusher in a correct oriented manner. Transmission, sliding rollers, pins and aprons are largely oversized to withstand the strains and impacts of the heavy lumps discharged in the hopper. The transmission, by means of motor and gearbox enables to obtain the desired feed quality during the work without stopping the machine.

Vibrating feeders, mod. AV, are used for secondary feeding of gravely alluvial or pre-crushed material.

Mainly made up of a plate chute hung over the fixed casing by ant vibrating rubbers and moved by two eccentric motor-vibrators. The continuous feeding and the constant capacity allow the machine that follows to work always at full rating. The feeding quantity can be adjusted by a circular sector placed on the discharge mouth or acting on the eccentric masses of the motor-vibrators.

Constrained vibrating feeders, mod. AW, are used for secondary and sometimes, primary feeding of gravely alluvial or pre-crushed material.

They are mainly made of a fixed frame and mobile carriage supported by four arms with articulated joints provided with special rubbers that do not need any maintenance. The carriage reciprocating movement, which causes the material slide, is given by a rod-crank system. Continuous feeding and adjustable capacity allow the machine that follows to work always at steady rating.
