Bulk material conveyors screw conveyor and silo design - material properties

The design of the bulk material (also known as bulk solid matter) transport system includes the transportation, processing and storage of materials. The basic nature of the material will have an impact on these processes. In addition, the bulk firmware material has a variety of composite properties. The same material will have different forms of reaction; humidity, particle size distribution, tightness, gas permeability and other parameters will have an impact on the reaction; even the conditions of the atmosphere, processing materials and reactions related. Therefore, engineers often face the problem of using limited knowledge to predict the operational performance of the system, such as:

How the material flows in the silo, hopper and Feeder, free flow or forced flow, uniformity movement or non-uniformity movement; whether the gas permeability is sufficient / absorbs moisture and agglomeration; corrosion or weathering effect; in the hopper Or the material in the silo is bridged. Arching or overflowing; adhesion or adhesion of materials due to static electricity.

These problems are all related to the basic nature and characteristics of bulk solid materials, which in turn determine the process, the method of transport and storage, and the type of equipment and equipment to which the system is selected.

In general, the properties of bulk solid materials can be grouped into the following categories: particle size, shape and density; physical properties; chemical properties; electrical properties and temperature effects.
