Moist granulation system for pharmaceutical and chemical industries
Transform powdered materials into uniform granules with efficient moisture control, minimizing air entrapment and ensuring consistent active ingredient distribution for enhanced product quality in pharmaceutical tablets and chemical catalysts.

Processes and Granulates Moist Materials
Alexanderwerk’s MG Series, including the GA 65, G 1/100, G 1/168, and G1/244, offers robust solutions for granulating moist and pasty materials in the pharmaceutical, chemical, food, and nutraceutical industries. These units feature counter-rotating cylinders for efficient granulation, resulting in uniform, rapidly soluble granules. With throughput capabilities of up to 2,000 kg/hr, these machines ensure high production output. The mobile design of the GA 65 enhances operational flexibility, while the equipment’s quick disassembly facilitates easy cleaning and maintenance. Available in various configurations, the MG Series meets standard industry compliance requirements, providing comprehensive support for customized engineering solutions upon request.
