Impact crusher and hammer crusher have their own advantages and characteristics. Which one to use needs to be determined according to the actual use environment. If the material to be processed has high hardness or high humidity, it is inclined to impact crushers. Otherwise, choosing hammer crushers is better. There are also users who choose the form of "hammer crusher + impact crusher" to make sand. These can be selected according to the actual needs of users. It is necessary to comprehensively consider the consideration of the finished aggregate size, environmental performance, and investment costs. Generally speaking, the feeding size of impact crusher is designed to be larger, and it is mostly used for making stones instead of sand, and the hammer crushing is finer, and it is used for sand making operations.

First, from the perspective of the particle size of the machine-made sand in the sand making operation, the hammer crusher adjusts the size of the finished product by adjusting the size of the sieve plate gap, so the particle size of the finished product is small and more powdery; and the impact crusher needs to adjust the speed or diameter of the rotor and the size of the opening of the distributor to adjust the particle size of the product. The final sand product by impact crusher  is generally cubic.

Second, from the structure of the crushing cavity, the crushing cavity of the hammer crusher is relatively small, and the sealing performance is relatively strong during operation. Therefore, it can effectively reduce dust and dust leakage from the machine body during the sand making operation, which is more environmentally friendly; the crushing cavity of impact crusher is relatively large. After the material enters the crushing
