Characteristics and Advantages
Based on our many years of technology accumulation in pharmaceutical industry and market trend analysis, the roller compactors from longlitek.com are aimed at the middle-end and high-end market, in order to meet the requirements of customers for high quality equipment.
As one of the earliest manufacturers of dry granulating machines in China, Longlitek was honored to be responsible for drafting the industry standard JB/t2017-2016 of China for dry granulating machines.
Roller Compactor is integrated of compacting, crushing and granulating process, can effectively reduce the content of fine powder in the granles, improve the quality of granules and increase the capacity of granulation, so as to make a good preparation for the subsequent tablet pressing, capsule filling processes or granules product. It can be used to produce the granules with desired size according to the different needs without any additive during granulating.
With various of roller compactors, Longlitek can meet the needs of different kinds of customer. Our roller compactors have the advantages of low comprehansive production cost, saving energy and non-contamination. So, they have been widely applied in the pharmaceutical, food and chemical industries, etc.
High-grade Automation of Control System By continuous iterative development, our roller compactor has high degree of automation, the main electrical components and control system are from the international famous brand products, to ensure stable and reliable operation of the equipment for a long time. It can realize the automatic control of flake thickness and adjust the operating parameters according to the difference of raw materials. The granule products granulated have good uniformity and consistency with high primary granulation rate and yield, and stable dissolution curve. According to customer requirements, we also can provide IPC for better control system. Main features of our control system include: Good human-computer interaction interface. The process parameters can be adjusted steplessly. Closed-loop control of control system. Reliable and perfect alarm function. Multi-state control module. Automatic operation is stable and reliable. Fully ensure the safety of man and machine. Easy to operate, overhaul and maintain.

Main Structure and Innovation of Our Roller Compactor
Smooth-feeding Stirring Hopper
Smooth-feeding Stirring Hopper The first issue to be solved for dry granulation is that the powder feeding is not smooth. Our company has two patents in the stirring feed device, which are respectively the Feed Mechanism with Compaction Device (patent number: ZL201320868375.0) and the Hopper Feed Mechanism (patent number: ZL201320581372.9). Using these two devices can effectively improve feed efficiency. Stirring feed device can ensure the stable feeding of materials; The feeding box is arranged in a vertical way to prevent the material from bridging. The natural exhaust channel allows the air to be discharged naturally to ensure the stable feeding materials.The compaction device ensures reliable sealing and convenient disassembly and assembly.
Uniform-feeding Screw Feeder
The material needs to be steadily and evenly fed to the compactiong area through the screw feeder. The screw feeding device of our company has two patented technologies, which are the Vacuum Exhaust Device of Feeding Mechanism of Roller Cpmpactor (patent number: ZL201420776419.1) and Double Screw Feeding Structure of Roller Comapctor (patent number: ZL201420736564.7), can effectively reduce the air content in the material, increase the compactness of the material, increase output of granulation. Parallel arrangement of double screws ensure the uniformity of material feeding, which is suitable for material feeding of large roller. Different types of screw feeder can be selected to adapt to different materials.
Stable Roller Compacting Unit
The roller compacting Unit is the core mechanism of the roller compactor. We optimize the structure of the roller compacting mechanism to ensure the stable pressure and uniform material density in the roller compacting process. Closed-loop control of roller gap ensures the consistency of flake thickness. Special structure of hydraulic device or roller double support structure can meet the requirements of high pressure. By special heat treatment, the rollers with a variety of surface patterns can adapt different powder materials.
High-grade Automation of Control System
By continuous iterative development, our roller compactor has high degree of automation, the main electrical components and control system are from the international famous brand products, to ensure stable and reliable operation of the equipment for a long time. It can realize the automatic control of flake thickness and adjust the operating parameters according to the difference of raw materials. The granule products granulated have good uniformity and consistency with high primary granulation rate and yield, and stable dissolution curve. According to customer requirements, we also can provide IPC for better control system. Main features of our control system include:

Closed-loop control of control system.
Reliable and perfect alarm function.
Multi-state control module.
Automatic operation is stable and reliable.
Fully ensure the safety of man and machine.
Easy to operate, overhaul and maintain.
High-grade Containment and Safety Protection
The operation area, mechanical transmission area and electronic control system of our roller compactors are placed in independent areas, each area is in good airtight. According to different material characteristics and working conditions, we choose different sealing materials and sealing structure, to prevent dust leakage and pollute the mechanical transmission system and electrical system. In order to meet the higher requirements of some users for the operation safety, airtight and explosion-proof of the equipment, we have developed the containment isolated roller compactors, as well as the roller compactors with CE standards and ATEX standards.
Overall Structure Optimizated, Strong and Durable
Easy to Operation Our roller compactors adopt modular design with compact structure and good sealing, are easy to operate, adjust, dismantling, cleaning and maintenance. The main structure is made of fine and thick stainless steel materials, and the roller support base is made of forging parts with excellent performance, which makes the equipment stable and reliable in quality.
