Parallel twin-screw extruder, twin-screw granulator, which models are used in what occasions? What is it used for?
SHJ-20B/ 400RPM/500RPM/600RPM: laboratory model, mainly used to test whether the formula is feasible and the production process is reasonable; The explored data are only used as experiments and paper references, and all data cannot be directly amplified to use on large equipment;
SHJ-35B/35D/35G, 400-600RPM; Laboratory and small batch order production equipment, for the smallest type of production equipment, generally used for small batch multi-variety orders, but also can be used to test the reliability of the formula and the rationality of the production process; The experimental and operational data can be directly amplified to larger primary equipment and other large twin-screw granulation equipment. This kind of equipment is often the first choice for color manufacturers;
SHJ-50B/50D/52B/52D, 400-600RPM, this model is used for both particle quality and production capacity during granulation;
SHJ-65B/65D,400-600RPM, this model is used for modified products with a capacity of 150-200 kg per hour, which has taken into account the requirements of production capacity;
SHJ-75B/75D/75G, 400-600RPM, large capacity modification, granulation and sheet extrusion often used such equipment;
SHJ-95B/95D, 400-600RPM, large capacity modification, granulation and sheet extrusion require large capacity, will be used as the preferred equipment;
SHJ-110B or SHJ135B, 400RPM, large capacity requirements when the configuration, huge investment amount, have high requirements for power consumption and transformers, generally not recommended as a new user;

What is the L/D ratio about the twin screw plastic extrusion machine?
L/D is Length by screw diameter ratio, it means
Length-diameter ratio is the ratio of length to diameter.
For example, the diameter ratio of 50 machine is 40:1, which means the length =50x40=2000mm, it's also the length of shafts, but it isn't the length of the HOST's basement;
Normally, the L/D ratio of each barrel is 4:1;
