The blade is a vulnerable part. Some customers may need to change it in two months, some in three months and some in six months. Generally speaking, the blade must be replaced in the first half of the year. Of course, because of the different raw materials, the material of the grinder blade itself is not the same, which will affect the service life. Today, let's talk about how to use the blade of pulverizer and how to grind it to make the blade use longer and longer. Before turning on the crusher, screw the machine back on. This is to prevent the screw from falling down. Although the blade is said to be of high hardness, it can not withstand a screw of 20 mm. Once touched, the blade is absolutely scrapped. Of course, this includes paying attention to the fact that there are no iron blocks in the waste plastics when feeding. The year before last, a customer told me that all the blades were scrapped. At that time, he didn't dare to tell me the reason, only said that the blade quality problem. Well, in line with the customer's above, quality-oriented belief, I am unconditional to the other side to send some blade, (the material used by the customer is 9CrSi.). Two months later, our company's technicians went out for sale to maintain the machine. The customer also warmly invited our technicians to have a meal. I'm sure I have to drink when I eat. I'll drink a lot of wine. He started telling the truth after drinking. Tell us the mechanic said that the operator of their company accidentally threw a hammer into my machine.

So please use the machine friends must pay attention not to let iron and stone into the grinder, in order to avoid damage to the blade. And then there's the grinder. The blade of the pulverizer will be blunt if it is used every day. The tool used in grinding directly affects the service life of the blade. Our most common and ideal is to use a surface grinder to grind the blade, which has good effect and high precision. Also excellent for blade protection. However, in some places, there are few surface grinding machines, which are not available at customers' homes. It is also a joke to buy a plane mill for grinding blades. It's not a realistic thing.

It's not practical to buy a plane grinder, so our best choice is to get a grinder. General automatic knife grinder is composed of slide rail, gear, motor, water pump and electric box. Although the accuracy of the grinding tool is not as good as that of the plane grinding machine, it can also be regarded as a small grinder. And the price of knife grinder is more popular. Most customers can afford it. The worst thing is to use a common grinder as a grinder to grind the blade. This way is the most harmful to the blade. You can imagine what it would be like to grind a stone on a blade. This is almost the same. Although the blade can be ground out, the tip of the blade is broken. This way is used to grind the blade. A pair of blade top grinding three or four times can be replaced with a new blade. Therefore, it is not recommended for friends to use, of course, in helpless circumstances, it is useless. Then grind it. Naturally, you have to be ready to buy a new blade. Finally, let's talk about some points for attention when grinding the blade of the grinder. Some shredder blades in the use of the process, may make a gap. The whole blade looks like a pit. It's not good. But when you sharpen the knife, don't think about one to smooth the gap and then sharpen the blade. Leave this gap open. If you smooth this gap, it is estimated that the blade edge has been worn out. For the service life of the blade. Just grind the edge of the knife to make it tough.
