As a common screening equipment, drum screen is widely used in many industries, such as mining, building materials, chemical industry, food processing and other fields. The correct selection of drum screen is crucial to ensure production efficiency and product quality. The following are the main bases for drum screening type:
1 Material characteristics
1.1 Particle size distribution: The particle size of the material directly affects the screening efficiency. Materials with different particle sizes need to match different sieve hole sizes.
1.2 Humidity: If the material contains a high moisture content, it may affect the screening effect and even cause the sieve hole to be blocked. Therefore, it is necessary to select a drum screen type suitable for wet material screening.
1.3 Viscosity: Some materials have a certain degree of adhesion and are easy to stick together to form lumps. At this time, it is necessary to select a drum screen with a special design (such as a knocking device installed inside).
2 Production capacity
Determine the diameter and length of the drum screen according to the required processing volume. Generally speaking, the larger the diameter and the longer the length of the drum screen, the stronger the processing capacity.
3 Screening accuracy
Select the appropriate screen specifications according to the particle size requirements of the final product. The sieve hole size determines the particle size range of the final product.
4 Equipment size and site restrictions
Before choosing a drum screen, consider the size of the installation space and whether it is easy to maintain.
5 Energy consumption and environmental protection requirements
Choosing equipment with low energy consumption and environmental protection standards can reduce production costs while also responding to the call for green production.
6 Economic efficiency
On the premise of meeting the use requirements, comprehensively consider factors such as purchase cost, operating expenses and subsequent maintenance costs.
7 Reliability and durability
The working environment of the drum screen is usually harsh, so its structural strength and durability are also one of the factors to be considered when selecting.
8 Automation degree
With the development of automation technology, many drum screens are equipped with automatic control functions, which can automatically adjust parameters such as speed according to actual production conditions to improve work efficiency.
In summary, choosing a suitable drum screen requires comprehensive consideration of factors such as material characteristics, production capacity, screening accuracy, etc. The correct selection can not only improve production efficiency, but also reduce operating costs and extend the service life of equipment.
