A drum granulator is a molding machine that can make materials into
specific shapes. Rotary drum granulator is one of the key
equipments in the compound fertilizer industry. It is suitable for
cold and hot granulation and large-scale production of high, medium
and low concentration compound fertilizers. The main working method
is wet granulation of agglomerates. Through a certain amount of
water or steam, the basic fertilizer is fully chemically reacted in
the cylinder after being humidified. With the help of the rotating
movement of the cylinder, the material particles are formed by
extrusion force and agglomerated into balls.
