Charcoal sample making technology field.
Background technology
Coal and ore this kind of quality is uneven, staple commodities for being determined the price with matter, needed in transaction according to national related
Standard, successively sampled, sample preparation, the links such as analysis, can just obtain representing the result of laboratory test of bulk sample.
In process of preparing coal sample, coal sample size will pass through 13mm, 6mm, 3mm, 0.2mm from big to small, and what crushes crushing,
13mm to 6mm and 6mm to the most frequently used equipment of 3mm stage crushings be hammer mill.
The monomer hammer mill structure that coal sample preparation at present uses is substantially the same, and has hopper, hopper above crusher chamber
There is manual gate between crusher chamber, for controlling charging rate.This control method cannot be guaranteed stable, continuous-feeding, easily
Feeding is excessive, too fast, causes crushing motion component stuck, need to clear up crusher chamber, time-consuming and laborious, stuck for a long time also to cause
Driving motor damages.Crushing effect is undesirable, and buildup can lead to certain overcrushing.
Chinese invention patent《The automatic feeding mechanism of hammer mill》（The patent No. 201010267993.0）, disclosed in
Technical solution, feed inlet are located at the top of broken warehouse, and using motor screw driving seal apron opening and closing, material leans on free gravity
Falling bodies mode is fed, and charging rate is uncontrollable uneven, easily generates feed blocking feed inlet or material concentration is deposited in brokenly
In broken warehouse, cause crushing motion component stuck.
Cracking hammer head needs to regularly replace as vulnerable part, and hammer mill crusher chamber is divide into upper part and lower part at present, on
Half part and hopper, tup belt pulley etc. link together, and folding is heavy when opening cleaning crusher chamber.Tup is mostly using hammer blade
Or ring hammer type, mounting structure is more complicated, and when replacement is also time-consuming and laborious.
Since hopper is located above broken cavity, cause device height high, multiple batches of tens kilograms of materials add in, and work is simultaneously
Not easily.It works in the case where feed, broken, splicing each section are unable to sealing state, it is impossible to prevent moisture loss, it is impossible to obtain full water
Divide analysis result, water analysis result can there are deviations.
As it appears from the above, at present coal sample preparation field monomer hammer mill there are delivery rate completely by manual control,
Crusher chamber and hammehead structure are complicated, the reasons such as complete machine height height, cause to block up, crushing effect is undesirable, cleaning operation folding is heavy,
Tup is not easy to replace, and it is that the utility model crusher will solve the problems, such as that feeding is heavy etc..
