FAQs:
  • What is the principle behind the Double Roller Extrusion Granulator?
    The granulator operates on the principle of roll press compaction, where two synchronized, counter-rotating rollers apply extreme mechanical pressure to raw powder material, forcing it through precisely designed molds to form a dense sheet that is then broken into uniform granules.
  • Can this machine handle materials other than fertilizers?
    Yes, the Double Roller Extrusion Granulator is highly versatile and can process a wide range of materials including chemicals like pigments and resins, minerals such as metal powders and ores, and even powders in the pharmaceutical and food industries.
  • Does the dry granulation process require any additional drying steps?
    No, the dry granulation process produces granules without adding moisture or liquid binders, which eliminates the need for subsequent drying steps, making the process more efficient and economical.
  • How is the granule size and shape controlled?
    Granule size and shape are controlled through the precisely designed molds on the roll surfaces and the subsequent crushing and screening process. The equipment allows for customization to meet specific product requirements.
