Description

Technical Field

[0002] Powder transfer and feeding is a key link in the transfer and quantitative feeding of powdered materials (such as chemical raw materials, pharmaceutical intermediates, food additives, etc.) in industrial production. This process involves transporting powders from storage containers or transportation equipment to production equipment.
