Description
Technical field
The utility model relates to a kind of coal mining equipment, and in particular to a kind of sorting of lump coal and crushing device composition
The comprehensive crushing device of mining lump coal.
Background technique
The unearthed coal mine in mine is required to be crushed it before transport utilizes, and is coal mine granule fines by its fragmentation
After transported and be formed utilization, preferably have impact breaker and hammer to coal mine product crushing effect in existing crusher
Formula crusher is mainly crushed using shock power, applied widely, and crushing members abrasion is small, and replacement is convenient, compared with
Usually applicable knife, which breaks to crush formula crusher with double roller and compare, has the advantages that have very much, but it has one for the partial size for putting into raw material
Provisioning request, coal mine are most of to generally require for whole block structure when being crushed using above-mentioned crusher after being unearthed
It is pounded in advance and hits processing as fritter raw material, waste a large amount of time;Hammer mill is as broken equipment in one kind, after being crushed
Material particular diameter it is larger, also need to carry out finished product again sometimes it is fine crushing, it is very troublesome, be tiny in addition, raw material is after investment
The mixture of particle and raw material block, a large amount of fine particle need to be fallen by castor item put into together after, be easily caused at this time
Material accumulation at castor item, not only influences the crushing effect of block material, while castor item also being be easy to cause to block, therefore actually broken
Before, sieve is often advanced with by mixture and carries out screening separation, and the material block side investment of bulk carries out coarse crushing, whole process
Practical operation is very troublesome.
It exists in the prior art and the broken patent of gradation sizing largely is carried out to lump coal, principal mode is all first to use
Hammer is broken or jaw crusher carries out level-one and is crushed, and then carries out two-stage crushing by kibbler roll.Level-one is broken and second level is broken
Material is sieved by screening plant between broken, the investment kibbler roll that particle is unsatisfactory for requiring is crushed,
What grain was met the requirements is directly sent at finished product.This mode, extremely complex for a set of equipment, especially moving component,
Two sets of crushers, maintenance cost are very high.Also it will increase dramatically equipment purchase cost.
In addition, lump coal is before entering crushing plant, pre-screening is highly desirable, and the repetition that can reduce qualified material is broken
It is broken, energy consumption is reduced, is also prevented from that lump coal particle is too small, the big problem of dust emission occurs.But existing pre-screening is sieve screening,
It is very easy to blocking sieve pore, follow-up work efficiency is caused to decline or directly shut down.But it in existing technology, does not clear up effectively
The device of sieve, reciprocating sieve pair and cohesive particle have preferable effect, but the particle being stuck in sieve pore can not be removed,
It uses for a long time, the work efficiency drop of whole system can be made.But replacement sieve requires to shut down substantially, very troublesome.
