Graphite provided in this embodiment crushes and nodularization system, including:Sequentially connected feed hopper, jet microniser, rotation Wind grader, shaping feed bin sum aggregate material unit;Wherein, collection material unit includes:Weighing silo, shaping grader, finished bin and useless Product storehouse, shaping feed bin are connected with weighing silo, and feed inlet of the weighing silo also with shaping grader is connected, shaping grader it is whole The discharge port of shape section is connected with the feed inlet of finished bin, the discharge port of the classification section of shaping grader and the feed inlet phase in waste product storehouse Even, finished bin is connected with waste product storehouse, and finished bin and waste product storehouse are connected respectively with a buffering bucket;Waste product storehouse and shaping feed bin difference It is connected with first air-introduced machine, jet microniser is also connected with air blower.By above system, material passes through jet stream powder successively The crushing of broken machine and the shaping of shaping grader, so as to material is crushed and nodularization during, without increase crush With the number of shaping so that graphite crush and nodularization system output increased within the unit interval.
If the material particles into system are smaller in itself, powder is carried out so as to be directly entered jet microniser It is broken, it is just broken with regard to needing to carry out at this time but if the material particles itself into system are bigger, be by the crushing material of bulky grain The material of smaller particle, and then into jet microniser so that jet microniser crush it is just easy.
Fig. 2 show the structure diagram two of graphite crushing provided in an embodiment of the present invention and nodularization system, is when entering When the material particles of system itself are bigger, as shown in Fig. 2, on the basis of Fig. 1, above-mentioned system further includes:Squirrel-cage crushes Machine 8,
Squirrel-cage crusher 8 is connected by feed hopper 1 with jet microniser 2.
In the present embodiment, material can be carried out just to break by increasing mouse cage crusher, can effectively avoid big material in jet stream Cycle crushes back and forth between pulverizer and shaping grader, can effectively reduce the particle cycle pulverized time, improve unit The processing grain amount of jet microniser in time improves unit interval production capacity.That is, by setting squirrel-cage crusher and jet stream Pulverizer so that material is carried out continuously just broken between jet microniser, between without reciprocal, be it is unidirectional, so as to Avoid temporal extension.
And to be exactly primary crush be not achieved design object to the principle of the prior art, is crushed with regard to continuous several times, during crushing material Between it is long.And after being broken at the beginning of having mouse cage crusher, jet microniser, which is dealt with, to be easy for mostly.
Further, as shown in Fig. 2, feed hopper 1 includes:Big hopper 11 and small hopper 12;
Squirrel-cage crusher 8 is connected with big hopper 11, and big hopper 11 is connected with small hopper 12, small hopper 12 and jet mill Machine 2 is connected.
Above system further includes:First star-shaped feeding machine 13 and the second star-shaped feeding machine 56;
Wherein, big hopper 11 is connected with small hopper 12, including:Big hopper 11 passes through the first star-shaped feeding machine 13 and small hopper 12 are connected;
