Belt conveyors are widely used transportation equipment in metallurgy, coal, mining, ports, electric power, building materials, chemicals, light industry, food, machinery and other industries. They are suitable for conveying various granular materials with a bulk density of 0.5-2.5t/m³. Powder and other bulk materials can also be transported into pieces.
The design and calculation of the belt conveyor must have the following original data and working condition data:
1. The name and delivery volume of the material;
2. Material properties: including particle size and particle size composition, bulk density, dynamic or static accumulation angle, temperature, humidity, viscosity, abrasiveness, corrosiveness, etc. The unit mass and external dimensions of the finished article are also included when transporting the finished article.
3. Working environment: open air, indoor, dry, humid, ambient temperature and air dust content, etc.
4. Unloading method and unloading device form.
5. Number and location of receiving points.
6. Conveyor layout (side type) and related dimensions, including conveyor length, lifting height and maximum inclination angle, etc.
7. The layout of the drive device and whether it is necessary to set a brake.
The belt conveyor must have the above parameters at the initial stage of design to determine the conveying volume, conveying speed, conveying distance, etc., and to correctly select the entire conveying system, which is a very important step. When selecting a model, if the designer chooses a model smaller than the one actually needed, the parts of the designed belt conveyor may be damaged during use, or even the conveyor is completely scrapped, causing huge economic losses; if the designer chooses If the model is too large, it will increase the cost of the conveyor and waste resources.
The designer can calculate the minimum requirements of each component based on the above parameters, and select the appropriate components according to the "Criteria for Transport Machinery Selection". It is worth noting that due to the lack of accurate material characteristics-especially the operation at different belt speeds Relevant information such as stacking angle. It is almost impossible to accurately calculate the delivery volume. Many variable factors will affect the driving force on the driving drum, and it is also very difficult to accurately determine the required power. Therefore, the accuracy of the design calculation is limited and can meet the requirements of most situations. In addition, for some complex conveyors, especially important conveyors, it is best to consult experienced experts.
