After promoting the new electronic weight grading machine, which named Rotary grader, Zhengzhou First Industry received some questions about the collection between elevator and buffer belt. One of the good questions is how to control the speed of elevator to avoid accumulation at the beginning of buffer belt.
Firstly, we tested the most suitable speed and fixed it when installing the machine for customers. This method works of course no problem, but our manager Wu not satisfied with it. During the brainstorming among our team, a new function was added.

Comparing between the first machine and this new one, nothing much different on the surface. We add only a small device on the elevator and buffer. It may look like a piece of cake, actually it is.
Same as a math question, when you calculate a lot for a long time on the paper, still can not find the answer and feel anxiety, even give up, regard it as the difficult questions you can not solve. However, you will be afraid of this kind of question and think you can not do it from the bottom of your heart. First Industry is another student who never stop calculating as long as we have time. After trying for many different methods and calculate with one more page, we found the answer is actually so easy, a simple equation is enough to get the answer.
Whenever the question is easy or not, the process for calculate is important for everyone who want to get a long time progress. If just copy the result from other, we will never know clearly about the working principle and stop innovation.
