Note matters of using three roll mill

The Three Roll Mill is referred to as three-roll machine, generally divided into the experimental type and production type. Three roll mill is horizontally mounted three rollers so as to achieve constant speed of compression and friction grinding effect. It is currently the most effective grinding and dispersion equipment for high viscosity materials, mainly used in paint, ink, paint, plastic, pulp manufacturing industry.

 

During using grinding machine process, we have to pay attention to various matters. So that we can improve the grinding effect, to extend its use life.

 

1, before operation, we need to take a series of checks to ensure that the machine can be more normal and safe operation. First, you want to view the total power to see if the switch is normal. Moreover, we have to see whether the circulating water is cooling or not. Until the end of the all check, and there is no exception, you can begin to work.

 

2, when in operation Three Roller Mill, we also can not be careless, it is best to arrange people for care, to pay attention to its dynamics. For example, the observation of oil tank to see if there is oil overflow. Moreover, another point is to attach the roller debris, should be shut down for processing.

 

3,Finally, wait until after the three roll mill to stop working, it should not be set aside indifferent. Clean-up of the grinding machine is very important, so is the same for the three roll mill. Production after our best to be timely cleaning, the first roller should be washed, but we can not ignore the health of the Grinding Machine around.

 

In fact, do the safe operation is very simple. Only need a little more patience, we can do the qualified production and the production of security.

The classification of Three Roll Mill grinding method

Three Roll Mill for grinding, and its methods In general, can be divided into wet grinding, dry grinding and semi-dry grinding these three kinds.

First, wet grinding, we turn also known as the deposited sand grinding in liquid abrasive uninterrupted add to smear the need for grinding the surface, so that we can make abrasive in machining parts between the lapping tool and do a sliding or rolling motion, and this will form the moral cutting movement as we know. Wet Grinding, this method is generally used in the processing of the initial coarse grinding stage.

Second, dry grinding, we again called embedded sand grinding in the surface layer of the lapping tool, abrasive suppress in which, and the requirements to achieve a uniform effect during the grinding time, we only need to research a coated the surface of a small number of auxiliary materials can be. The dry study of this method is generally used in the processing of the mid-fine grinding stage.

Third, semi-dry grinding, we turn called similar wetland research, re-grinding process, it is used for abrasive grinding paste rendered mushy, this grinding method can either use the manual manual can also be on the grinding machine to operate. When grinding using this method, the parts must be in before the grinding, pre-processing methods, the purpose of doing so is in order to achieve higher pre-processing sophistication, parts processed by this method, the general has a good finesse, the latter is mainly used in the processing, further grinding stage.

Different grinding characteristics of different grinding methods, applicable, is not the same, we should be combined to produce the quality of the parts according to the characteristics of the Three Roller Mill grinding methods, the sophistication of the finished product from the to be processed, processing cost and other aspects to consider, on balance, to make certain choices, so as to create a low-cost, high processing efficiency, and market competitive products, so that the company's profit margins to the next level.

The care and maintenance of three roll mill

Three Roll Mill is now widely used in a variety of industries, deficiencies and defects of its traditional grinding machines were improved, more advantages compared to conventional grinding machine. Magnetic grinding machine advantage of high efficiency, the quality of the products produced reliable and secure, easy to learn, without adverse impact on the operating personnel or the surrounding environment or pollution, can effectively reduce costs, to liberate the productive forces, thereby enhancing profit margins.

Repair and maintenance
First, the magnetic grinding machine polishing barrels leaking the end of thorns polishing the needle can be used pliers to remove, add a little glue.
Second, timing devices, magnetic grinding machine is not flashing, check whether they have to press the start switch, if not press, just press can be.
Third, the magnetic grinding machine polishing bucket of water if they are overheating, In general, under normal conditions, water temperature should be around 50 degrees Celsius, is too high, you must promptly change the water operating.
Fourth, a huge shock, magnetic grinding machine, you need to check whether the machine is placed on a smooth, while each corner by location, and more practical for the length of the adjustment.
Fifth, the directions of magnetic grinding machine showed normal, but the Basket Mills still does not cloud can check the voltage is 220 volts, or polishing the needle into the amount is too much.

Routine maintenance
First, the magnetic abrasive machine in the course of polishing liquid spilled into the machine should be cleaned timely, the purpose of doing so is to prevent the liquid to cause unnecessary damage to the surface of the machine.
Second, completion of the second, magnetic grinding machine stops running, to use a rag and cleaned the surface of the machine.
Third, the magnetic grinding machine when not in use, the need to control panel using plastic bags to trap the purpose in doing so can prevent the dust to prevent stains.
Fourth, magnetic Grinding Machine put the barrel polishing tank if polishing the needle exist, you need to make timely clean-up.
