Other brothers can use shot blasting machines, but shot blasting machines have higher construction costs and are not necessarily faster than milling machines.
It is just that the surface after treatment is flatter, but it is still pitted. Need grinding machinery. The processing effect of the chipping machine is similar to that of the milling machine, but because the chipping head impacts the beam surface vertically, it is easy to damage the internal structure of the cement concrete, and it requires an external air compressor and air pipe. It is not convenient to operate and use a milling machine. The work efficiency is not as high as the milling machine. It is worth noting that there are many small milling machines because of their very light weight, a small number of blades, and low power. The milling effect is similar to that of a grinder. It is recommended to use a small milling machine with a dead weight of at least 200 kg, an engine power of 9-13 horsepower, and a blade number of more than 100. There are several domestic [1] manufacturers that produce small milling machines that are relatively mature. The price of this type of milling machine is nearly 50% cheaper than imported similar products, and the average price is around 30,000.
