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 the drum screen is essential to ensure production efficiency and product quality. The following is the main basis for the selection of drum screen:
1 Material characteristics
1.1 particle size distribution: The particle size of the material directly affects the screening efficiency, and materials with different particle sizes need to match different mesh sizes.
1.2 humidity: If the material contains high moisture, it may affect the screening effect and even cause the screen hole to be blocked. Therefore, it is necessary to select the type of drum screen suitable for wet material screening.
1.3 viscosity: some materials have a certain degree of adhesion, easy to stick together to form a mass, then need to choose a special design (such as internal installation of knocking device) of the roller screen.
2 Production capacity
The diameter and length of the trommel are determined according to the required throughput. In general, the larger the diameter, the longer the length of the drum screen processing capacity is stronger.
3 Screening accuracy
Select the appropriate screen size according to the particle size requirements of the final product. The mesh size determines the particle size range of the final product.
4 Equipment size and site restrictions
Before choosing a trommel, 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 meeting environmental protection standards reduces production costs and responds to the call for green production.
6 Economy
Under the premise of meeting the requirements of use, comprehensive consideration of purchase costs, operating expenses and subsequent maintenance costs and other factors.
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 the type.
8 Degree of automation
With the development of automation technology, many roller screens are equipped with automatic control functions, which can automatically adjust the speed and other parameters according to the actual production situation to improve work efficiency.
In summary, the selection of the appropriate roller screen needs to consider the material characteristics, production capacity, screening accuracy and other factors. The correct selection can not only improve production efficiency, but also reduce operating costs and extend the service life of equipment.
