DT fixed belt conveyor has a feature of large capacity, simplified construction, easy maintenance, standardized components. DT conveyor of belt is widely used in mining, metallurgy, chemical and other production sectors. It is used to transport relax material and member goods, according to the request of transport technology. It can be used in single, multiple or combined with other equipment to form horizontal or incline transportation system to satisfy different production line arrangement needs. 1. The DT conveying quantity is worked out by the following conditions: material density is between 1.0t/m3-1.6t/m3; conveyor obliquity is less than 18o and the material stockpile angle is 30o. 2. Density of material is less than 2.5t/m3. 3. The DT conveying length is not restricted to the form; different length can be manufactured according to customers' demands.
