This new Rotoform system has a solidification capacity one third greater than the company’s existing high-speed model. The increased capacity of the new Rotoform HS2000 is achieved through the use of a wider depositor and steel belt, enabling throughput rates of up to 400 TPD. The system is based on the same principle as other Rotoforms in the range, with the product to be solidified being deposited in the form of droplets across a continuously running steel belt. As the steel belt travels along the system, cold water is sprayed against the underside, and heat is transferred from the droplets – via the steel belt – to the cooling water. This controlled solidification ensures the production of premium quality monogranules of 2-4 mm in diameter. With virtually no dust or vapor emissions and no need for subsequent screening, remelting, or de-watering, the process has minimal environmental impact and satisfies all current international legislation.
