Horizontal shaft impact crushers (also called horizontal shaft impact crushers or impact crushers) for recycling concrete play a key role in the concrete recycling process. The following is a detailed introduction to this equipment:
Working principle of impact crusher
Horizontal shaft impact crushers use high-speed rotating rotors to drive impact hammers or plate hammers to impact concrete materials entering the crushing chamber at high speed. After being impacted, the materials will rebound and collide along the wall of the crushing chamber for many times, and further crush into smaller particles. At the same time, there is also an impact plate inside the crusher, and the materials repeatedly collide between the impact hammer and the impact plate, and finally crush to the required particle size.
Features of impact crusher
1. High crushing efficiency: The horizontal shaft impact crusher adopts high-speed impact crushing method, which can quickly and effectively crush concrete into the required particle size.
2. Strong adaptability: The equipment can handle concrete materials of various hardness, including concrete containing impurities such as steel bars and gravel.
3. Adjustable finished product particle size: By adjusting the gap between the impact plate and the rotor, the particle size of the crushed material can be controlled to meet the needs of different uses.
4. Energy saving and environmental protection: The equipment is reasonably designed, stable in operation, low in noise, and meets environmental protection requirements.
Easy maintenance: The equipment has a simple structure, few wearing parts, easy maintenance, and reduced operating costs.
Application of impact crusher
In the process of concrete recycling, the horizontal shaft impact crusher is mainly used to crush the waste concrete into aggregates that meet the requirements. After screening and impurity removal, these aggregates can be directly used in the production of recycled concrete or used as a substitute for building materials. This can not only reduce the exploitation and consumption of natural resources, but also reduce the cost of processing construction waste, and achieve resource recycling and sustainable development of the environment.
Recommendations for the selection of impact crushers
When selecting a horizontal shaft impact crusher for recycling concrete, the following factors need to be considered:
• Processing capacity: According to the scale and processing requirements of recycled concrete, select an appropriate processing capacity.
• Material characteristics: Consider factors such as the hardness and impurity content of concrete materials, and select a suitable crusher model and configuration.
• Finished product particle size requirements: According to the requirements for aggregate particle size for subsequent uses, select a crusher model and configuration that can meet the needs.
• Environmental protection requirements: Consider local environmental protection policies and standards, and select low-noise, low-emission crusher equipment that meets the requirements.
• Cost budget: According to the cost budget and economic benefit analysis, select cost-effective crusher equipment.
