The method provided by the invention has the advantages that the crushing effect is good, the production efficiency is high, the production cost is low, and the like.
Description
Technical field
The present invention relates to a kind of breaking method, particularly the breaking method of the difficult processing materials such as a kind of long fibre and lignin.
Background technology
Corn is wide in the cultivated area of China, and according to statistics, annual corn (the comprising corncob) output of China is approximately 1.5 hundred million tons, and the output of corncob accounts for-half left and right of total output.Although corncob can as replacement of fuel coal or natural gas, but, this Land use systems also exists the problem of the wasting of resources, experimental study shows, corncob is sugary 54.5%, crude protein 2.2%, crude fat 0.4%, crude fibre 29.7%, mineral matter 1.2%, therefore, and determination that can be beyond all doubt, if only burned as fuel, the value of corncob is not fully utilized.As everyone knows, corncob can be used as the feed of pig or ox, also can, as the base-material of plantation edible mushroom, can also indirectly be used as to produce the higher industrial products of the added value such as furfural and xylitol.Below the prerequisite be effectively utilized is that corncob must be pulverized, and corncob belongs to the stronger material of long fibre plasticity, adopts common breaking method can cause material particles englobement, beat more real and more real, be difficult to pulverize and screen, not only reduce production efficiency, but also add production cost.
Summary of the invention
For above-mentioned technical problem, the invention provides-kind of crushing effect is good, production efficiency is high and production cost is low for the breaking method of the difficult broken material of the long fibres such as corncob.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of material breaking method, comprises the following steps: 1) material precrushing; 2) through described step 1) drying materials after precrushing process is consistent to its inside and outside moisture content; 3) through described step 2) to be cooled to its water content be 11% for material after process; 4) will through described step 3) screen after cooled material fragmentation; 5) through described step 4) oversize repeating said steps 4 after screen), until all materials all reach the first broken standard; 6) material reaching the first broken standard is carried out screen after pulverization process, until the material after pulverizing reaches the second broken standard.
Described step 1) adopt the unequal oppositely rolling roller crusher of roll body diameter to carry out precrushing to material.
Described step 2) adopt tunnel type drying case to dry 1h-1.5h at 70 DEG C-85 DEG C after, sampling cools and measures the inside and outside moisture content of material, if the inside and outside moisture content of material not-cause, then continue described step 2), otherwise, continue described step 3).
Described step 4) adopt hammer mill or roller pulverizer comminuting matter.
Described step 4) middle employing 70 order-90 object pneumatic jig screen materials.
Described first broken standard is 70 order-90 orders.
Described step 6) adopt pulverizing mill to carry out pulverization process to material, described second broken standard is 300 order-325 orders.
The dust that shattering process produces adopts pulse dust removal device processes.
The present invention is owing to adopting above technical scheme, its technique effect reached is: 1, due to the present invention adopt tunnel type drying case 70 DEG C-85 DEG C by drying materials to it inside and outside moisture content consistent, and the material after above-mentioned PROCESS FOR TREATMENT is cooled to moisture content is at normal temperatures down to less than 11%, therefore, effectively can improve plasticity and the fragility of material, and then reduce the difficulty pulverized.2, due to the present invention by through first time pulverize after material through pneumatic jig screen, the material being greater than or equal to the-broken standard is pulverized again, and the material being less than the first broken standard is carried out screen after pulverization process through pulverizing mill, until reach the second broken standard, therefore, crush efficiency and the economic benefit of material is substantially increased.3, the dust produced due to shattering process of the present invention adopts pulse dust removal device processes, therefore, greatly reduces the pollution of the broken environment of dust in crushing process.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is schematic flow sheet of the present invention.
Detailed description of the invention
Research shows that the plasticity of corncob or wood chip and water content have direct relation, namely water content is less, fragility is larger, more easily pulverize, based on above-mentioned characteristic the invention provides-kind for the breaking method of the difficult broken material of the long fibre such as corncob, comprise the following steps (as shown in Figure 1):
1) the unequal oppositely rolling roller crusher of roll body diameter is adopted to carry out attrition crushing to material;
2), after adopting tunnel type drying case to dry 1h-1.5h at 70 DEG C-85 DEG C, sampling cools and measures material inside and outside moisture content, if the inside and outside moisture content of material is inconsistent, then continues this step, otherwise, continue next step;
3) through step 2) material after process is cooled to moisture content at normal temperatures and is down to less than 11%;
4) through step 3) material after process adopt beater grinder or roller pulverizer to pulverize after with 70 order-90 object pneumatic jig screens;
5) oversize not reaching broken standard repeats step 4), until all broken things all reach the broken standard of 70 order-90 objects;
6) the material pulverizing mill reaching broken standard carries out pulverization process, screen, and reaching 300 order-325 object materials is qualified powder.
The dust that above-mentioned shattering process produces adopts pulse dust removal device processes.
Above-mentioned embodiment is intended to illustrate that the present invention can be professional and technical personnel in the field and realizes or use; modifying to above-mentioned embodiment will be apparent for those skilled in the art; therefore the present invention includes but be not limited to above-mentioned embodiment; any these claims or description of meeting describes; meet and principle disclosed herein and novelty, the method for inventive features, technique, product, all fall within protection scope of the present invention.
