The safe operation process of three roll mill

Three roll mill belongs to a category of the grinding machine, in fact, three roll mill, also known as three roller mill, three roll mill can be divided into three roll mill experiments using the three roll mill and the production and use of these two. Three roll mill is mainly applied to inks, paints, pigments, pulp manufacturing process, can be described as the application is a very wide range of functions is relatively strong.

Overall, the performance of the product is relatively stable, but also easy to clean, not a lot of trouble in the replacement of materials, due to these features, of course, is widely used in factory processing industries, it is another initiative for the fineness require very small quantities of materials for grinding and dispersion.

Have an initial understanding of the three roll mill, the familiarity of the operating process is also essential. The age of the scientific operation of the process will be extended machine, the most critical is to extend the life of the Chemical Equipment, which is the vital interests of the enterprise are closely related to.

Practice for three roll mill is divided into four main points, Shift operation, before starting the preparatory work, boot, shutdown.

1, shift operations: three roll mill to open the check, mainly to check the three roll mill, three roll surface is clean, there is no debris in between rolls, and cutting to scraping blade is not sharp, and then is to see The lubrication part is not enough lubrication, not enough lubrication can add a little oil.

2, before starting the preparation. Work: to release the drum in accordance with the order, this time, we should also release to open the cutting knife, the next step is to file tip slightly release, will be prepared in advance, have been cleared and clean, then the slurry tank, then the cooling water valve to open.

3, start the main work is: to start the three roll mill, will file the tip to be appropriate compression, and then immediately added material, adjust the slow roll, fast round, and then move closer to the middle, look carefully at the roller surface is not parallel, then to regulate the tightness of the drum. Cutting scraper adjustment pressed, observe the size of the pressure, all the roll surface to the scraper blade Ministry paste real bend is limited. File tip elastic is no leakage to the limit, the amount of cooling water at the same time to observe the ammeter pointer rotation, can not exceed the rated current and voltage. Then check the fineness of the slurry. Based paint slurry fineness of the situation, adjust the degree of roller elastic and cooling water.

4, shut down the main work: paint slurry flow is finished, a small amount of the same variety of paint to conduct drum scrubbed clean, and release the drum, the file tip and cutting scraper, parking and cooling water valve is closed, the file tip, scraper, then Lacquer Tray clean mechanical cleaned.

These are the safe operation of knowledge of the three roll mills, of course, is not very comprehensive, if you want to learn more, you can consult Sower Group's engineers.
