Dry Granulation Machine LGCS100

What is the granulator used for?

Pelletizers are essentially rotary grinders used to grind scrap parts and melt delivery systems (gates and runners) into feed-sized particles for reprocessing. This enables moldmakers to reduce waste and produce components in a more economical manner.

What is the difference between wet granulation and dry granulation?

Dry Granulator uses mechanical compression (blocking) or compaction (rolling) to promote agglomeration of dry powder particles, while wet granulation uses a granulation liquid (binder/solvent) to promote agglomeration through adhesion to form wet agglomerates.

Factors affecting the rate and size of pellets produced by the Dry Granulator

1. Roller speed

2. Feed speed

3. Roll Design

4. The difference between the shape and size of the screw

5. Cohesion, density and flow characteristics of powder

6. Granularity

7. Machine Type

8. Die diameter

Pharmaceutical uses of Dry Granulator

1. Use a dry granulator when the drug cannot be compressed well after wet granulation.

2. Dry granulator is the best choice for aspirin, vitamins and other drugs sensitive to moisture.

3. It is used for granulation of heat-labile drugs.

Dry granulation applications supported by CANAAN

CANAAN has a global customer base and can therefore understand the wide range of industry applications that use our rolling technology.

Typical applications include:

Pharmaceutical

The success of all processing stages depends on a well-conditioned powder.

Health products

A high-quality product depends on creating the ideal powder.

Food

Particle size optimization can improve product consistency, flavor and texture.

Industrial/Chemical

Improve powder properties through precise control/flexible optimization from development to production.

Granulation Process

    LGCS100 Dry Granulation Machine uses the latest rolling control technology. This equipment can adjust any fluctuation of physical properties (such as local unevenness) between different materials and different batches of the same material, so that the process parameters (such as processing capacity, sheet density, rolling pressure, speed, etc.) of dry granulation can be accurately and repeatedly adjusted, thus producing high quality products efficiently.

    Particles usually have corresponding particle size requirements. After roll pressing, the final particles can be produced only after the crushing of the granulation system. Through the control system, the  granulation system is adjusted to produce particles with relatively stable particle size.

Principal Structure

FEATURE

New drive method

• All drive structures are driven by servo motor, which makes the operation more precise. The left and right pressure rollers can be operated independently or in combination, and the speed adjustment is more precise. Due to the independent driving system of the left and right pressure rollers, it is feasible and convenient to adjust the clearance of the left and right pressure rollers on-line. The rotation of the pressure rollers and the adjustment of the clearance are independent of each other and there is no interference.

Innovative roller gap adjusting system

• To avoid contamination and maintenance difficulties in the hydraulic system, a servo motor and related drives are used to precisely control the roller gap.

Unique feeding system

• With the synchronous operation mode of horizontal and vertical feeding, the feeding system consists of two feeding screw. The unique operation control ensures that the material will not be blocked.

Adjusted rotation speed and angle of rotor

• Most Dry granulator rotor can only be rotated in one direction. Using the motor servo drive, the rotor can realize the forward and reverse rotation, and adjust the rotation speed and angle, so the milling effect will be better.

  
  

  
  

Automatic Control System

• High Speed Control Processing Unit

• Roller speed control

• Pressure force control

• Torque control

• Roller gap control

  
  

Unique Inflatable Sealing Structure

• The front side of the granulating area is equipped with tempered glass door, which is convenient to observe the real-time production. The inflatable sealing ring is arranged around the glass door. the inflatable sealing structure is adopted to seal the glass door, so that the closed production can be realized.

Ajustable screen basket

• The Chamber is equipped with a spray head，which can realize the function of washing in place。In the process of granulation, a large amount of dust will be produced in the chamber。The Washing-in-Place can effectively prevent the dust pollution hazard after the production stop

Cooling Rollers

• In order to ensure the normal operation of the rollers, the rollers can be cooled by circulating water according to the demand. The circulating water cooling circuit is integrated in the equipment and disposed on the back of the equipment , avoiding the production area.

Unique Cleaning System for Closed Cleaning

• The cleaning ball is installed in 9 parts, and the equipment can be cleaned in the key area without disassembling the parts.

Vacuum Vent Device(Option)

• Vacuum vent can make the material more compact.This technology can exhaust excess gas in the material to improve material compactness and make the material squeeze more efficient. 

Security

• This machine is made of stainless s steel, and the nonmetallic material which contact with powder all meet with FDA requirements. In addition, Hercules-100 Roller Compactor has a fully enclosed granulating system which is cleaner and more in line with GMP requirements.
