LGP-160 Roller Compactor Slugging Machine E​xtrusion-Spheronization Granulator

LGP-160 Roller Compactor Slugging Machine Extrusion-Spheronization Granulator 

with Fully automated PLC control 

The LGP Series Roller Compactor is an integrated roller compactor system combining feeding, compaction, crushing, granulation and discharging functions, capable of directly converting powder materials into granules. It is particularly suitable for processing moisture-sensitive and heat-labile materials that may degrade or agglomerate. This equipment is widely used in pharmaceutical, food and chemical industries.

Powder materials (single or pre-blended) are fed into the hopper and conveyed by the horizontal screw to the compaction zone between dual parallel pressure rollers. The powder is compacted into flakes, crushed, and sized to granules. Granules are discharged via vacuum discharging to an optional vibrating screen for sieving to target specifications.

The operation panel provides automatic/manual modes. Pre-set process parameters (including screw conveying speed, Roller Compacting pressure/speed/gap) control the tableting sequence to ensure uniform feed and achieve target tablet thickness/density.

Powder Compaction Behavior Characteristics

Process Flow Diagram

1) PLC automatic control, color touch screen human-machine interface is friendly, easy to operate.

2) After the material enters the feeding hopper, it is stirred by the mixing impeller and enters the screw feeder, which is fed by the screw and the rotation speed is continuously adjustable;

3) Two parallel rollers are specially treated to increase loading capacity and strength;

4) The roller chamber is completely closed and its compression is observed through the organic glass panel;

5) The roller adopts water circulation cooling structure, in order to prevent thermal deterioration of special materials;

6) Rollers with different surface shapes can be quickly replaced according to process requirements;

7) The main drive motor (roller) adopts frequency conversion speed regulation, the rotation speed can be continuously adjusted, and has the upper and lower limit control of rotation speed;

8) Parts in contact with the material shall be made of stainless steel or food-grade polymer materials;

9) The pressure applied to the roller and the roller clearance can be displayed and adjusted on the touch screen;

10) The milling device can change the screen according to the need to obtain different mesh number of material granules;

11) By changing the speed ratio between the screw feeding and the roller, granules of different thickness and hardness (or specific gravity) can be obtained;

12) With the setting of machine parameters and working mode, and the function of password protection, failure alarm and help menu;

13) The machine equipped with horizontal twin screw feeding and unique cantilever type design, which improves the range of materials treated and the success rate and yield of granulating;

14) Water-cooled roller, the production of materials will not affect the performance of the material due to temperature rise;

15) The rollers are made of special stainless steel by special process, and its surface has high hardness and wear resistance;

16) The whole machine is of high quality stainless steel construction, all material contact parts are 316L, which fully meets the GMP requirements of drug production;

17) The feeder is designed with a vacuum exhaust port, which can effectively discharge the air in the material when the screw is feeding, so that the feeding is more compact. Unique vacuum exhaust system, does not cause equipment temperature rise.

18) The working area is separated from the transmission area to achieve clean and closed production from powder to granules, effectively preventing dust and cross contamination, and all parts in contact with materials are easy to disassemble and clean.
