Parallel twin screw pelletizing line/granulation line

Parallel twin screw pelletizing line/granulation line

Product description

The main machine adopts the principle of building block design. Its screw configuration, barrel structure, aspect ratio, feeding and exhaust setting quantity, number changing and dicing method, electric instrument automatic control mode, etc. can be adjusted according to the material system and process requirements. , optimize the configuration, and realize the unified consideration of multi-function, multi-purpose versatility and adaptability to characteristics;
The basic screw element is a fully meshed conjugate type, designed by computer, with excellent self-cleaning and arbitrary interchangeability. With the help of rich experience and software in the research and development of screw type for many years, various functions such as conveying and plasticizing, mixing and kneading, shearing and dispersing, homogenizing and homogenizing, exhaust devolatilization, pressure building and extrusion can be realized as needed. crafting process. In response to the endless new polymer materials and new processes, various new screw elements and combination configurations have been introduced accordingly;
The connection between the screw element of the main engine and the mandrel adopts the form of involute spline synchronized with the horizontal, which fully excavates the limited structural space, and takes into account the realization of higher working torque and larger working volume of the screw;
Depending on the requirements of different material processes and uses, on the basis of conventional A series (n≤500r/min, T/A3＜6) and high-speed B series (n≥600r/min, T/A3＜6) products, the newly launched High-torque C series (n≤500r/min, T/A3>8) and high-speed and high-torque D series (n≥600r/min, T/A3>8) products provide users at all levels with wider choices.
The new torque distribution transmission device strengthens the design margin, the high-precision hard tooth surface grinding process, the key bearings are all imported, the lubrication system is interlocked for protection, and the pursuit of higher reliability;
Various forms of metering and feeding structures and systems, single-screw, twin-screw, hollow spring, meshing and non-meshing, etc., can cover various material states. In addition to conventional low-cost volumetric feeding and metering, breakthroughs in the realization of high (0.5%) loss-in-weight metering systems; unique granulation systems, water-cooled strand pelletizing, air-cooled strand pelletizing, and air-cooled die face eager cutting granules, water ring die surface hot dicing, eccentric water mist hot dicing and underwater die surface hot dicing, etc., as required;
The material of the mandrel is 40CrNiMoA, the material of the screw element is the alloy tool steel W6Mo5Cr4V2, and the high temperature vacuum quenching place. Overall hardness HRC62-64. The barrel material is made of 45 steel, the splayed hole is made of double alloy bushing, and the wear-resistant alloy a-101 (Fe-Cr-Ni-B+Carbide) hardness is HRC60-64, which can meet the requirements of most operations. For special material conditions, special materials and treatment methods such as corresponding corrosion resistance and wear resistance can be selected;
The important components of the electrical instrument automatic control system are all imported, equipped with an interlocking control system, and the oil lubrication system is interlocked with the main engine, that is, the main engine can only be started after the oil pump is started. The feeding system is interlocked with the host, that is, the feeder can only be started after the host is started. The pressure system is interlocked with the main engine, that is, the main engine and the feeding material will stop working when there is overpressure. The current is interlocked with the host, that is, when the overcurrent occurs, both the host and the feeding stop work. In addition to the conventional instrument mode, it can be provided with analog operation panel, PLC system, PCC system or large computer workstation control system, etc.;
Low vibration, low noise, the whole machine can be installed without foundation and placed on a flat ground, which meets the requirements for the site and installation, and is more convenient to use.
