Abstract
A pulverizing process for phenoplast using grinding rollers features that mechanically broken material is directly filled in grinding machine using rollers which rotate in opposite directions with different speeds. Said grinding machine is an improved wheat flour one having such parameters as 0.3-0.6 mm of back lash between fast and slow rollers, the ratio of fast roller engagement to that of slow one Z=10, and opposite rotation with 2.5:1 speed ratio. Its advantages include low cost, uniform granularity of phenoplast particles, and no over-breaking.
Description
The present invention relates to field of plastics processing, especially a kind of phenolics milling roller disintegrating technique.
At present, the phenoplasts production at home and abroad overwhelming majority all adopts two roller mill hot-rollings refinings to be moulded sheet, and pulverize the cooling back, is that the sector is produced difficult and is the last key together of yield rate quality but pulverize always, is regarded as brainstorm subject for a long time.Its particle diameter distribution of pulverizing finished product by this explained hereafter is very inhomogeneous, and the above fine powdered thing of 80 orders will account for more than 35% of total amount, is called as crushing phenomenon.Particularly in recent years, thermosetting plastics is applicable to automatic compacting, injects, is transmitted into and moulds, its plastics have the plasticizing piece, quick solidifying demoulding die clamp is difficult for producing bubble, the product surfacing, and therefore powder shape and the particle diameter distribution to phenoplasts proposed new requirement, promptly require the powder degree between 40 order to 60 orders, fine powder more than 80 orders is few more good more, and present domestic great majority use cintrifugal disintegrator patterns, force sheet type, toothed disc type, worm-gear type, but these all can not reach the requirement of expection.
The object of the present invention is to provide the process that a kind of technology is simple, equipment cost is low, produce the good difference of the speed in opposite directions roll-in pulverizing phenoplasts of product cut size degree.
Technical scheme of the present invention is: it is in blocks with phenoplasts to be that raw material carries out hot machine roll-in, and carries out Mechanical Crushing, material is sent into the difference of speed in opposite directions after special repacking again rotate flour mill and carry out in opposite directions speed difference abrasive dust and pulverize the back packing and dispatch from the factory.The cornmill of the flour mill employing food processing field employing of speed difference rotation is a parent in opposite directions, two pairs of speed running roller transformations of the way therebetween are: (1) diameter is identical, (2) nibbling shape adopts helix to nibble, each inch number of teeth is 10, (3) the speed running roller is nibbled cutting edge of a knife or a sword to nibbling the cutting edge of a knife or a sword installation, and the velocity ratio of (4) speed running roller is 2.5: 1.
The inventive method is owing to adopted transformation of the way speed difference roll-in pulverizer in opposite directions. and original production stage is reduced, because the gap of speed running roller can be adjusted, make material be rolled into satisfactory product according to production requirement, through test, smalls more than phenolic aldehyde molding powder product 80 orders that carry out with the inventive method is below 10%, and production cost reduces greatly, and output is doubled and redoubled.
Fig. 1 is a process frame chart of the present invention;
Fig. 2 is the structural representation of abrasive dust in opposite directions of the present invention;
Fig. 3 is the scheme of installation of the speed of abrasive dust in opposite directions running roller of the present invention.
Set forth most preferred embodiment of the present invention below in conjunction with accompanying drawing down, as shown in the figure that phenoplasts are in blocks also through after the Mechanical Crushing through the hot pressing roll-in, the material after the fragmentation is sent into fast in opposite directions difference flour mill advance pulverizing, its material package is dispatched from the factory.Speed difference flour mill adopts all-purpose flour machine such as the MG3-SM in the food processing field in opposite directions, and two pairs of speed running rollers in the above-mentioned cornmill are reequiped: (1) fast running roller (1) is identical with slow running roller (2) diameter; (2) nibbling shape is that helix is nibbled and changed 10 tooth Z=10 of each inch into; (3) distance of shaft centers between fast, slow running roller is a diameter D+0.3 millimeter; (4) fast, slow running roller is nibbled cutting edge of a knife or a sword to nibbling cutting edge of a knife or a sword and install as the showing of Fig. 3, and adopts in opposite directions direction to rotate, and is fast, the speed between running roller is 2.5: 1 slowly.
Claims (2)
1. phenolics milling roller disintegrating technique is that raw material carries out following procedure of processing with phenoplasts:
(1) phenoplasts are in blocks through hot machine roll-in;
(2) carry out Mechanical Crushing;
It is characterized in that to send into after the fast in opposite directions poor rotation grinding roller pulverizer of special repacking carries out speed difference rotation grinding roller pulverizing in opposite directions, can pack through the material after (1), (2) step process dispatching from the factory.
2. a kind of phenolics milling roller disintegrating technique according to claim 1, it is characterized in that rotating the all-purpose flour machine that the grinding roller pulverizer adopts food to add the field through the speed difference in opposite directions of special repacking is parent, its original two pairs of speed running rollers are reequiped adjustment, its fast running roller (1), the diameter of slow running roller (2) is identical, it is identical to nibble shape, all adopt 7 °-8 ° helical tooth, the centre-to-centre spacing of its two running roller is the diameter D+0.3-0.65 millimeter of running roller, hurry up, the number of nibbling of slow running roller is Z=10 for 10 teeth of each inch, fast running roller (1), slow running roller (2) adopts nibbles cutting edge of a knife or a sword in opposite directions to nibbling the cutting edge of a knife or a sword installation, make fast, slow running roller relatively rotates, and keeps fast running roller and the velocity ratio V=2.5 that takes turns slowly: 1.
