Putty powder spray machine need not match grinding machine?

We know that many customers when using the machine, often blocked gun, or local card dead, investigate the reason, is because there are impurities in the putty powder, there are particles, or putty powder is not fine enough.

Therefore, many people in the purchase of putty powder spraying machine, will match a grinding machine, the role of the grinding machine is to grind putty to spray.

But the grinding machine also has a lot of shortcomings, such as slow grinding speed, need to be ground in advance with good putty, otherwise can not keep up with the speed of putty powder spraying machine, this will delay the work.

The price of a grinding machine is around 2000. If you don't need it, you can't spray it.

We can use a large filter to filter the putty and spray it.

So machines are dead, people are alive, we can think of a way to solve this problem.
