What are the advantages and disadvantages of impact crusher？

The advantages and disadvantages of impact crusher (sand making machine) are as follows:

Advantages
High efficiency and energy saving
High crushing efficiency, low energy consumption, large crushing ratio, can realize fine crushing and coarse grinding functions, suitable for medium hard, extra hard and abrasive materials.
Low energy consumption, high output, novel structure, balanced operation, small equipment size, simple operation, easy installation and maintenance.
Excellent product particle shape
The product is cubic, with extremely low needle-like content, high bulk density, extremely low iron pollution, and meets the standards for construction sand.
Strong wear resistance
A small number of easily worn parts are made of extra hard and wear-resistant materials, with small size, light weight, easy replacement, and the equipment has a self-lining function to reduce wear.

Strong adaptability
It can handle a variety of materials of different hardness, such as limestone, granite, basalt, etc., and has low requirements for material humidity, and the water content can reach 8%.
Environmental protection and energy saving
The working noise is less than 75 decibels, with less dust pollution, and can effectively reduce dust diffusion during the crushing process.
High degree of automation
Equipped with an automated control system, it can realize remote operation and fault diagnosis, improve production efficiency and safety.

Disadvantages
Limited effect on fine aggregates
Almost ineffective for aggregates below 10 mm, low yield, generally only about 35%.
Wear problem
The fixed wall of the impact crusher (such as hammer head, impact plate, etc.) wears faster when crushing hard materials, and wearing parts need to be replaced frequently, with high maintenance costs.
High requirements for material particle size
The feed particle size needs to be controlled within a certain range. Materials that are too large or too small will affect the crushing effect.
Low production yield
The output rate is relatively low, the loss is large, and screening equipment is required to improve the yield.
Large-scale equipment is difficult to operate
For large-scale equipment, operation and maintenance are difficult and require professional personnel to operate.
