The mechanical series parameters, transmission power and tension calculation methods of DT Ⅱfixed belt conveyor are used ISO international standards, the first phase of the union design completed the main parameters spectrum and the main components of the design of the original TD75 main parts, and also increase the same the strength components series design of the chemical fiber conveyor belt.
DTⅡ type has significant improvements and breakthroughs.in the application of the drive power scope, high-performance gear unit and the advanced drive parts，the rollers carrying capacity and types, the various carrier rollers types ，structure and the diameter, the strength of the conveyor belt and varieties compared to DT75 type.
DT Ⅱ use conditions ：
Transport loose density 500-2500KG/m3 various bulk materials. General working environment temperature -25 ℃ -- +40℃,  for special environments if have special requirement such as heat-resistant, cold-resistant, waterproof, anti-corrosion, explosion-proof, flame retardant, and other conditions should be separate proposed in order to take appropriate protect measures.
The main components species of the tape:
A，According to rubber surface divided into flat rubber-faced belt(transmission angle less than 20), pattern rubber-faced belt (transmission angle less than 25);
B, According to the rubber surface core classified as: the ordinary canvas belt, nylon belt, polyester belt, steel cord belt;
C, According to belt width classified as: B500, B650, B800, B1000, B1200, B1400, B1600, B1800, B2000, B2200, B2400.
All kinds of belt width applicable auxiliary send material slope in the list below:
