Working principle and structure of hammer crusher
Hammer impact
crusher is mainly made of electric motor crate, rotor, impact plate and
actuating device, suitable for medium hard and light erosive materials. It
integrates the advantages of hammer crusher
and jaw crusher, which has the
advanced design concepts, top-ranking design technology, such as higher ratio of
reduction, more evenly crushing size and lower power consumption.
The hammer
impact crusher is applicable crushing brittle minerals, such as: limestone,
basalt, granite, cobble, feldspar, fluoride, and concrete, with compression
strength no more than 300Mpa and humidity no more than 15%, is widely used in
the industry of mining, cement, building materials, water conservancy,
metallurgy and chemicals. It can secondly and fine crush materials.
Working
principle: When materials enter the working area, they'll be struck by the
hammers on the rotor and be thrown onto the impact plate. The materials which
spring back from the impact plate will be struck by the hammers again until they
reach the desired size, after which the materials will fall through the mesh
under the rotor. The distance between the impact plate and the rotor can be
adjusted to meet shape and size requirements.
Performance and structure of
hammer crusher
There are many types of hammer crushers, according to the
structure characteristics they may be classified as follows:
1. According to
the number of the rotor, there are the single rotor hammer crusher and double
rotor hammer crusher;
2. According to the rotary direction, they are
reversible (rotor into two directions) hammer crusher and not reversible hammer
crusher;
3. According to the row number of the hammer, they can be divided
into single type hammer crusher (the hammer are installed in the same rotary
level) and many platoon type hammer crusher (the hammer distributes in several
rotary levels) ;
4. According to the connection of the hammer with the rotor,
they can be divided into fixed hammer crusher and flexible hammer crusher. Fixed
hammer crusher is mainly used for finely grinding the soft materials. We'll
introduce these content in the following sections.
Hammer crusher is widely
used in cement, chemical, metallurgic industry and so on for crushing
medium-hard stuffs, such as limestone, slag, pet coke, coal, etc. The final
product can be adjusted according to customers demand through equipping
different gratings. Jaw Crusher is one of main equipment of stone crushing, is
ideally suitable for crushing all kinds of ores and crushing the big size
materials, the highest anti-pressure strength of crushed material is 320
Mpa,having two types: primary crushing and secondary crushing.jaw crusher has
been sold to 75 countries, the price and quality of jaw crusher is widely
recognized, we always stick to be your satisfying partner.
