ZL Series

The product is gently pressed to cylindrical granules, the granules will be more compact than YK series oscillating granulator.

In the product chamber of the basket granulator, two rotors operate in counter rotation. The upper rotor ensures good mixture and carries the material downwards. The lower extrusion rotor compresses the material and extrudes it through the screen sieve.

The basket granulator is often used in pellets with a porous structure and large surface area, easily dispersible granulate, such as drinks powder, sauces and soups, detergent, pesticides and so on.

ZK Series

Basket Extruder models are available with capacities from bench level scale to over 1,000 Kg/hr.

Separate basket extruder designs for pharmaceutical and industrial applications are manufactured to meet industry standards. All extruder models are easily cleaned and have appropriate shaft seals protecting the feed material from contamination.

The Basket extruder can be stand-alone or linked to aspheroinizer or a fluid bed dryer and continuous vibratory dryer to form an integrated system.

XZK Series

With our rich industry experience and knowledge, we are engaged in offering high quality Basket Extruder, this is a basket type extruder for pharmaceuticals, foods, confectioneries, fertilizers, chemicals, etc., which is matching GMP and simple constructions.

Basket has two faces of holes (Upper & lower), so even if one face is damaged, smooth operation can be done by using another face.

The blade can be lifted up and down for pre-mixing, so that the wet powder will be more uniform.

What Are the Working Principles?

Wet mixed powder (raw material) is added into the feeding hopper. In the upper chamber of our basket extruders the counter rotating internal breaker bar system breaks larger clumps of wet powder to allow gravity to convey the wetted mass down into the bottom extrusion rotor arms which, in turn, densifies the material and extrudes it through the screen sieve. Formed materials are discharged without damage by our proprietary discharge chute design. After drying, finished product will be obtained.

What's the Operation Process?

Blade
The blade and rotary knife move in opposite directions, so that the wet powder squeezes out of the screen hole. By extruding, the wet powder makes into granules. (The blade of XZK series can be lifted up and down).

Rotary Knife
It is located under the blade, standard knives are curved. Only the rotary knife of XZK series can adjust the gap between knives and screen sieve, because the knives are bolted to a star.

Cutting Knives
Granule length can be controlled by adjusting the gap between cutting knives and screen sieve. A located pin helps the cutting knife to fix on the place.

Screen Sieves
The screen sieves are made by SS304, also it can be SS316L. The hole size is according to your requirement. A screen sieve is made by flange, plate and reinforcing ring.
