Overview:Powder shape material was sent into main feeder by vibration hopper, material will be degassed on the function of main feeder stirring screw, then put to the roller. Two roller rotating and press the powder to compact material piece.

Content

Principle
    Vertical feeder
    Powder shape material was sent into main feeder by vibration hopper, material will be degassed on the function of main feeder stirring screw, then put to the roller. Two roller rotating and press the powder to compact material piece. Material piece will drop to the sieve after leave, and remain material piece will be scraped down by scraper. After sieving, finished granule could be gotten, sieved fine powder will be sent back for circulation granulating.
Applications
    GZL dry granulator is mainly used the process of dry extruding granulating, it could compress the raw material which water content less than 10% from powder to tablet, then after crushing, granulating and sieving, finally make the granules.
    The dry granulator is mainly being adapt outer pressure, enforce the raw material pass through the small gap between two rotating roller wheel and become tablet. In the way of pressing, practical density of raw material could be 1.5-3 times than usual and could meet the need of strength.。

Application
    Our company develop the dry granulator specialized for medicine on the basis of absorbing foreign advanced technology. Compared with former dry granulator: it’s granule forming rate, efficiency, cleaning and maintaining has a big improvement. Processing part is divided with transmission part, dividing design of driving device, control part and product could meet the requirement of GMP. The equipment support more flexible, fast assemble and dissemble, contact material part as stainless steel.

Feature
    1 Raw material forming through mechanical pressure, there is no need for any solution, and could keep the purity of product.
    2 Forming from dry powder to granules directly, no need drying process. It is more benefit for produce process.
    3 The strength of powder is high, improvement of specific gravity is more obvious than other method of granulating.
    4 It could reduce the pollution to environment, reduce waste of powder and cost of packing, improve product transport ability.
    5 Compact in construction, easy in maintaining and operation, short process time, low energy consumption, high efficiency, low failure rate, suitable for a wide range of raw materials and the pressure between roller wheel is adjustable.
    6 Feeding device is adapted frequency control, high automation, it could realize one man control, low in labor strength.
    7 Main transmission parts is use high quality alloy material, stainless steel, titanium, chrome and others, make the machine could endure corrosion, high temperature and pressure, make the longer using life of machine.
