How to choose suitable screening equipment to improve the quality of machine sand?

Screening equipment plays a crucial role in the production process of machine-made sand, as they can separate sand and gravel aggregates of different sizes, ensuring that the products meet the standard specifications of construction sand. Choosing suitable screening equipment to improve the quality of machine sand requires consideration of the following aspects:

1. Screening efficiency
Efficient screening equipment should be able to minimize the possibility of material clogging the sieve holes, such as improving screening efficiency by adopting appropriate screen surface design and reasonable vibration methods. For materials with high moisture content, screening equipment with bouncing balls or ultrasonic vibration can be selected to reduce screen surface blockage.

2. Screening accuracy
In order to ensure accurate separation of different particle sizes of machine sand, screening equipment needs to have precise mesh sizes. For multi-layer screening, the mesh size of each layer of screen should be accurately matched according to the product particle size requirements.

3. Processing ability
Processing capacity is one of the important parameters of screening equipment, which must match the production capacity of the entire production line. Too low processing capacity can lead to production line bottlenecks, while too high processing capacity may increase unnecessary investment.

4. Structure and Material
Select the appropriate structure and material based on the characteristics of the screened material. For example, for corrosive or highly worn materials, screening equipment should be made of corrosion-resistant or highly wear-resistant materials.

5. Maintenance simplicity
A good screening equipment should be easy to maintain and clean, such as easy replacement of screens, simple structure, and easy maintenance.

6. Environmental performance
Considering the increasing environmental requirements, screening equipment should minimize dust and noise pollution as much as possible. It can be equipped with a sealing structure and noise reduction measures, while also being connected to a good vacuum system.

7. Automation level
Modern production lines tend to be highly automated, and screening equipment should be able to achieve seamless integration with the entire production process, such as automatic monitoring, fault alarm, and other functions.

8. Manufacturer's reputation and service
Choose a manufacturer with a good market reputation, as the screening equipment they provide is often of higher quality and reliability. In addition, good after-sales service and technical support are also important factors in ensuring the stable operation of the production line.

Taking into account the above factors, through careful comparison and on-site investigation, selecting high-quality, high-performance, and suitable screening equipment for one's own production line will help significantly improve the quality and production efficiency of mechanism sand.
