Basket Granulator

Basket Granulator Introduction

Hywell machinery Basket Granulator（also named rotary granulator/extruder granulator/rotary basket extruding granulator）is a device for extruding wet materials through the sieve of a stainless steel sieve barrel with an S-type milling cutter. Through the wire sieve, the wet powder raw material can be ground into granules, and the rotary granulators can also be widely used to crush the granules that have become lumps and become ready-made granules. Basket granulators can discharge the materials auto, and the basket granulation reaches the requirements of GMP, the extruder granulator is one of the best granulators. The basket granulations make the materials mixed into the desired grains. It is especially suitable for materials that have high viscosity. It has a high grain-making and shaping rate, perfect in the grain exterior appearance. Its automatic material discharge will avoid the grain damage caused by the manual material discharge. The extrusion granulator is suitable for flow production. The graduation machine’s structure is reasonable and its external appearance is beautiful.

ZL series basket granulator is usually the key equipment of the wet granulation production line. The pellet production line includes the following equipment: CH sigma mixer or GHJ high shear mixer, YK series oscillating granulators or ZL series basket granulator, Centrifugal Spheronizer, dryer (such as vibrating fluidized bed dryer, static fluidized bed dryer, vertical fluid bed dryer, or hot air oven), and vibration sieve. This production line can make the dry powder into uniform and instant granules. If the customer wants to make the final pellets into a ball shape, the wet pellets will be sent to the QL pelletizer to obtain wet pellets and dried by a dryer.

Hywell Machinery has laboratory machinery for the factory or experimental agency product development stage, please pay attention to hywell company's laboratory rotary basket granulation machine.

Basket Granulators Description

Materials are gravity fed into the extruder granulator and are wiped through perforated screens by extrusion blades creating cylindrical extrudates of a controlled diameter. Extrudates then fall onto a rotating table for discharge to the next processing step.

In the upper chamber of our basket extruders machine, the counter-rotating internal breaker bar system breaks larger clumps of wetted feed material 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 basket. Formed extrudates are discharged without damage by our proprietary discharge chute design.

Components of a Basket Granulator

1. The Basket and sieve

The basket is the central component of a basket granulator. It is a cylindrical container with a perforated base and side walls. The basket is responsible for holding the material being granulated and allowing the granules to pass through.

The sieve comes in a perforated metal sheet. It functions as a mesh screen and wraps around the basket. With a stainless-steel construction, the sieve works to grade and screen the particles crushed by the rotating rotor.

The basket granulator sieve is available in various sizes and perforated types. Sieve helps achieve the desired particle sizes depending on your production needs. Our sieve has a round. The perforated metal sheet's smallest hole is 1.5mm.

1.1 Types of Baskets

Basket granulators come in different types of baskets, including fixed and removable baskets. Fixed baskets are permanently attached to the granulator, while removable baskets can be easily removed for cleaning and maintenance purposes.

1.2 Materials Used for Baskets and Sieve

Baskets and sieves are made from different materials, including stainless steel, and carbon steel. Stainless steel is the most common material used for making baskets due to its corrosion resistance and durability.

2. Impeller

The impeller of the rotary basket granulator is a rotating component that is responsible for mixing and agitating the material inside the basket. The impeller ensures that the material is uniformly distributed and that the granules are of uniform size and shape. The impeller is placed inside the basket and rotates at high speeds to create a centrifugal force that pushes the material against the basket's walls.

2.1 Impeller Design

The design of the impeller affects the efficiency and effectiveness of the granulation process. Impellers are designed with different shapes and sizes, and the number of blades also varies. The impeller design should ensure that the material is well-mixed and that the granules are of the desired size and shape.

2.2 Materials Used for Impeller

The impeller is made from different materials, including stainless steel, and carbon steel. Stainless steel is the most common material used for making impellers due to its corrosion resistance and durability.

3. Drive Mechanism

The drive mechanism is responsible for rotating the impeller inside the basket. It is made up of several components, including the motor, belt, and pulleys.

3.1 Motor

The motor is the main component of the drive mechanism and is responsible for providing the power needed to rotate the impeller. The motor's horsepower and speed depend on the size and type of the basket granulator.

3.2 Belt

The belt is responsible for transferring the power from the motor to the pulleys. It is made of rubber or synthetic materials and should be properly tensioned to ensure efficient power transfer.

3.3 Pulleys

The pulleys are responsible for transferring the power from the belt to the impeller. They come in different sizes and materials and should be properly aligned to ensure efficient power transfer.

Advantages of Basket Granulators

Basket granulators offer several advantages over other granulation equipment, including:

Uniformity

Basket granulators provide uniform mixing, ensuring that each granule is the same size and shape. This consistency is essential for tablet and capsule production.

Efficiency

Basket granulator machines are efficient, producing high-quality granules in a short amount of time. They can handle large batches and are easy to clean and maintain.

How do the Basket Granulator Works

An basket granulating machine is a device for extruding wet materials through the sieve of a stainless steel sieve barrel with an S-type milling cutter. Through the wire sieve, the wet powder or dry granules of raw material can be ground into small granules, and the extrusion granulator can also be widely used to crush the granules that have become lumps and become ready-made granules. It can discharge the materials auto and makes the materials mix into the desired grains. extrusion granulation is especially suitable for materials that have high viscosity. This powder granulating machine is high in grain making and shaping rate, perfect in the grain exterior appearance. Its automatic material discharge will avoid the grain damage caused by the manual material discharge. The machine is suitable for the flow production
