‌Brief analysis of comparison between hammer and impact sand making machine‌

The choice between hammer and impact sand making machine should be based on material characteristics and finished product requirements. ‌Hammer crusher‌ uses high-speed hammer to crush materials, with simple structure and low maintenance cost (about 0.6 yuan per ton). It is suitable for processing medium and low hardness brittle materials such as limestone. The finished product is multi-angular and suitable for ordinary concrete aggregate. However, it wears quickly when processing high-hardness rocks, and the needle-like content is high (about 18%).

‌Impact sand making machine‌ adopts the "stone hitting stone" crushing principle. The material collides and crushes, and can efficiently process hard rocks such as granite. The finished sand particles are round (needle-like <8%), and the fineness modulus is flexible and controllable (2.2-3.0), which meets the high-standard machine-made sand requirements. However, the equipment has high energy consumption (power consumption per ton +0.8kW·h), and the initial investment is large.

Selection suggestions: If the raw material hardness is low (Mohs ≤ 5) and the sand quality requirements are average, hammer equipment is preferred; if high-hardness rock (such as granite) is processed and high-quality sand is required, impact equipment is more suitable. Actual cases show that the unit price of impact sand production can be increased by 15 yuan/ton, with significant long-term benefits.
