Feeders
and Screens:
Crushing
plants can only achieve high throughputs if they are combined with
reliable feeding,
discharge and separating
systems such as apron feeders, chain conveyors, reciprocating plate
feeders/vibro separators and grizzly feeders including classifying
screens, magnetic separators and belt conveyors.
The
ThyssenKrupp screening
program covers the most widely varying sizes and models for
optimum matching to the material to be screened. Depending upon the
requirements, the screen can have linear or circular oscillation or can be
the eccentric-shaft type. For extra-fine screening, screens with a
directly driven screen wire cloth are used. Wobbler feeders are used to
classify materials that prove difficult to screen. Depending upon the
fractioning, wobbler feeders with extreme high throughputs have a great
advantage in having no vibrating mass. Heavy-duty apron feeders are used
as feed and discharge conveyors in crushing plants to convey coarse and
abrasive materials such as limestone, hard rock, coal, ores and
overburden. Magnetic separators create strong magnetic fields to separate
ferrous metals out of rock, rubble material and concrete while the
material is passing over a feed or discharge conveyor.
Crushers:
Mobile,
semi-mobile and stationary ThyssenKrupp crushing plants
are in operation all around the world. Mobile crushing plants are built
ready-mounted on their own travel gear. Semi-mobile crushing plants are
moved from one location to the next as a piggyback load on separate haul
units. It was ThyssenKrupp that pioneered mobile crushing plants, thereby making
it possible to crush minerals directly at the site of extraction and
synchronize to the rate of mining advance, into sizes ready for conveyor
transport. Semi-mobile crushing plants are always to be recommended when
there are long periods between changes of location. Each crushing plant
comes ready to operate with its own feed hopper, feed conveyor, discharge
conveyor and material transfer belt. The size and design of the crusher
naturally depends upon the work that it is intended for.

Each
raw material to be crushed has its own specific features. Its nature and
desired final shape, the size of the final product and the expected
capacity of the plant all have to be borne in mind in the selection of a
suitable crusher. Krupp offers a wide range of crushers for an optimum
solution:
ThyssenKrupp gyratory
crushers
are real state-of-the-art technology and have been designed for high
throughputs and economical operation. They are used mainly as primary
crushers in ore mines, quarries, limestone and cement works.

ThyssenKrupp hammer crushers
were
developed for the crushing of coarse, medium-hard materials for the
cement, gypsum and limestone industries. They are available as hammer
impact crushers, single-shaft hammer crushers and double-shaft hammer
crushers. Hammer mills, on the other hand, are especially suited to fine
reduction, grinding, homogenizing, fiberizing and selective crushing of
natural and industrial products.

Impact crushers
have
been designed to cover the whole range from coarse to fine reduction. They
handle hard and medium-hard material, and are used especially in those
applications where a high degree of reduction and a cubic, stress-free
final product is called for; e.g. in the handling of coal, potash,
limestone, gypsum, slag, overburden, rubble material and asphalt.

ThyssenKrupp double-roll
crushers
are specialized machines for medium-strength, highly sticky materials such
as limestone, marl and contaminated clay but also for coal, oil sands and
overburden. On the other hand, roll
mills
are used for fine reduction processes with a low content of fines and for
all materials even up to corundum.

The ThyssenKrupp roll sizer is
capable of crushing hard rock with a compressive strength of up to 300 Mpa
as well as sticky, soft and medium-hard material, such as limestone, marl,
clay, coal and similar raw materials. The material is crushed by shear and
tensile forces generated by high torques at a low cicumferential speed
