Application of closed dry granulation machine in the production process of new materials
Date: 2025-11-14Read: 1
Dry granulation technology is crucial in the production of new materials. However, traditional dry granulation equipment often faces problems such as dust leakage, poor temperature control, and material adhesion, which affect production efficiency and product quality. Canaan TechnologyLGX210-85 closed dry granulation machinepassTargeted design and process optimizationEffectively addressing these challenges, becomingImproving the quality and production stability of engineering plastic pelletsImportant equipment.
►The core value of airtight design
The core advantage of the LGX210-85 closed dry machine design lies in systematically solving the key pain points of engineering plastic granulation.
Effective control of dust pollution:
🔹 Optimize the connection structure between the feeding hopper and the horizontal conveying shell, as well as between the conveying components and the granulation core area.
🔹 Adopting a card disc sealing design to connect the inlet and outlet.
🔹 The entire system significantly reduces the risk of dust leakage during the granulation process, improves the working environment, and reduces the health risks for operators.
Accurate temperature management:
🔹 The device is equipped with a built-in circulating cooling system, which can stably maintain the surface temperature of the extrusion wheel below 35 ℃.
🔹 Ensure that the temperature in the compression zone is controlled below the glass transition temperature of engineering plastics (such as PA6 ≤ 45 ℃), effectively preventing material degradation due to overheating.
Ensure the purity of materials:
🔹 The fully enclosed transmission design avoids the contact between engineering plastic powder and the external environment, reducing the risk of cross contamination.
►Optimization and Control of Key Process Parameters
The precise control of process parameters for the LGX210-85 closed dry machine is the key to ensuring particle quality.
Intelligent control of wheel pressure:
🔹 Adopting servo motor driven roller system.
🔹 Real time monitoring of compaction degree of engineering plastic powder.
🔹 The pressure regulation accuracy reaches ± 0.5kN/cm ², ensuring the uniformity of particle hardness (particle hardness dispersion coefficient CV<5%).
Dynamic balance of rotational speed and shear force:
🔹 The servo motor speed control device is equipped with intelligent torque monitoring function.
🔹 Dynamic optimization can be performed within the linear velocity range of 0.01-2.5 dm/s (decimeters per second).
This optimization helps to improve the molding rate of engineering plastic particles (up to 80%).
►Improvement of equipment durability and stability
In response to the characteristics of engineering plastic materials, the LGX210-85 closed dry machine has been reinforced in terms of material and structure.
Wear resistant and anti-corrosion design:
🔹 The main components in contact with materials, such as cavities, are often made of polished 304 stainless steel.
🔹 The horizontal conveying screw is made of 20Cr13 stainless steel.
🔹 The pressure wheel is made of 30Cr13 stainless steel that has undergone vacuum quenching treatment, with a hardness of HRC50 or higher, significantly improving wear resistance.
Adaptive gap adjustment system:
🔹 Equipped with an adaptive system with a gap adjustment range of 0.5-3mm, it helps maintain the stability and consistency of the equipment's long-term operation.
