Let's talk about the product knowledge that the sand making machine needs to know, and how to choose the manufacturer.
1. look at the appearance of the sand making machine. Whether the weld is uniform or not, the groove of the groove is not, the appearance of the machine is not beautiful, etc., if these are all right, this shows that the manufacturer's welding is no problem, the quality is trustworthy and has the premise.
2. touch the quality of the sand making machine. If you turn the belt wheel of the crusher to see if it can be easily rotated or revolved, it shows that the concentricity of the machine is better. If it doesn't move, there may be a problem of concentricity of the machine, or it will be placed for a long time, and there is a lack of lubricating oil in the bearing seat.
3. test machine is transported by air to the machine, listening to the sound and watching the vibration.
