Description
Technical field
The invention belongs to crusher technical fields, and in particular to a kind of hammer mill.
Background technique
Hammer mill is a kind of equipment with impulse form broken material, is divided into two kinds of forms of single rotor and birotor.
Hammer mill mainly uses and is crushed medium-hard material in the industrial departments such as cement, chemical industry, electric power, metallurgy, such as by grain
Operation broken or fine crushing in the progress of the materials such as the biggish lime stone of diameter, clinker, coke, coal.
Existing hammer mill mainly includes cabinet, the intracorporal rotor of case is arranged in and drives the motor of rotor rotation,
The inner wall of cabinet is additionally provided with beating lining plate；Top of the box is equipped with feed pipe, and the bottom of cabinet is equipped with sieve plate；Rotor is equipped with several
Tup.In use, starting motor, motor drives rotor rotation, to realize that rotor drives tup rotation, then launches into cabinet
Material makes material be broken by the impact material that tup rotates high speed, while a part of material is hit under the action of tup
Beating lining plate is hit, beating lining plate gives material one reaction force, so that material reverse movement occurs to hit in fact with tup again
Now it is crushed.Broken material drops down on sieve plate, and is sieved by sieve plate, and the big material of partial size is left on sieve plate, continues
It is crushed by tup.
But there is also following technical problems for above-mentioned technical proposal: 1, due to the partial size of the material of hammer crushing crusher machine compared with
Greatly, therefore it be easy to cause charging blockage；2, broken material is sieved by the way that sieve plate is arranged, by the biggish object of partial size
Material be left on sieve plate, when tup to the biggish material of partial size carry out again be crushed when, tup can hit sieve plate, cause sieve plate vulnerable to
Damage.In order to solve the above-mentioned technical problem, Chinese patent CN108654755A discloses a kind of hammer mill, discharge port lower section
Be provided with rewinding case, sieve plate is arranged in the rewinding case, rather than is set up directly on discharge outlet, avoid tup it is broken compared with
Sieve plate is hit when big material, also, the patent is additionally provided with precrushing portion in feed pipe, the material for entering feed pipe is carried out
Precrushing increases crushing efficiency and crushing effect while avoiding charging blockage.But the precrushing portion of the patent
For the pressing plate driven by driving portion, pressing plate easily breaks down when rolling to material and material can be hindered normally to fall,
It connects and results in blockage；At the same time, in use, the sieve plate with the associated air bag controlled of driving portion by moving for the patent
It is dynamic, discharging is carried out to the larger material sifted out, unloading efficiency is lower, and safety of structure is lower.
