Our DF feeder offers high and
reliable performance with a modular construction for short installation time
and can be configured to meet any needs.
The design without hopper allows material to be moved directly
onto the conveyor section.
The material forms its own storage,
eliminating expensive fabricated upper hoppers and structures.
The horizontal part is designed to
be submerged by the stockpilers and the front loader can run over the structure
without any damages.
The idle head is equipped with chain
tensioning system, which permits sledges to move within a predetermined range.
The tensioning system can be managed also if the head is completely submerged,
because the setting can be done from the free area after the metallic walls,
which helps to hold the material.
The metallic wing walls delimit the
receiving and the reclaiming parts which have also the function of bearing the
pile thrust and ensuring material extraction.
In these walls there is a manual layer limiter to be set during
In case of material with big grain
size, a one roller crusher can be installed in this position in order to reduce
the grain size.
The conveying system is composed by
two strong pin and bush chains linked by bolted scrapers in charge of carrying
forward a certain amount of material: extraction happens on the chain top
branch, where material lies onto anti wear shields.
Just to give you an idea of the
strongness of the scrapers, the weight of one scraper for the model DF 1500
(1500 mm nominal width of the feeder) has a weight of 50 kg!!
Several reclaiming casings convey
the extracted material onto a sloped path to reach downstream machine, usually
a belt conveyor which collects material from multiple reclaimers.
drive head is equipped with reduction gear-box, torque limiting device,
electric motor and is supplied with VFD to match changing requirements.
It can move a large amount of
material up to 2000 tons per hour.
Idle and drive wheels are in sectors for quick and easy
The speed of the chain is low (normally between 0.05 and 0.3
m/s), for this reason the lifetime of chain and scrapers is long and there is
no need of a dedusting system.
The feeder does not need dedicated
costly civil works and site preparation and what is important is that it is
mobile: if your layout will change after time, you can easily move the feeder
in a different position.
A single unit can be used to feed a
belt conveyor, but if your conveyor system has higher capacity, you can add
additional feeders to maximize the belt conveyor capacity.
In case of multi material handling, you
can reclaim and blend different materials onto the main conveyor belt,
utilizing several dozer feeders, each one extracting its own material from its
Setting the speed of each feeder, you can compose the recipe according
to the mix of material you need.
