DTⅡ、DTⅡ（A）型固定式带式输送机是目前国内统一设计的通用型系列产品，其主要参数及性能均符合ISO国际标准，广泛用于冶金、煤炭、港口、电力、建材、化工、石油等各个行业。由单机或多机组合成运输系统来输送物料，可输送密度为500∽2500kg/m³的各种散状物料及成件物品。

        DTⅡ、DTⅡ（A）型固定式带式输送机均按部件系列进行设计，机架采取了结构紧凑、钢性好、强度高的机架，机架部分、中间架和中间架支腿全部采用螺栓联接，便于运输和安装。

1. Purpose and main features

        DTⅡ and DTⅡ(A) fixed belt conveyors are currently a universal series of products designed uniformly in China. Their main parameters and performance are in line with ISO international standards. They are widely used in metallurgy, coal, ports, Electric power, building materials, chemicals, petroleum and other industries. A single machine or multiple machines are combined into a transportation system to transport materials. It can transport various bulk materials and finished items with a density of 500∽2500kg/m³. 

       DTⅡ and DTⅡ(A) fixed belt conveyors are designed according to component series. The frame adopts a frame with compact structure, good rigidity and high strength. The frame part, intermediate frame and intermediate frame legs are all made of Bolt connection for easy transportation and installation.

       本系列带速范围为0.8∽6.5m/s，其中常用值为0.8∽5.0m/s。各种带宽适用的物料最大块度见表1，带速、带宽与匹配能力见表2。（注：1、输送能力系按水平运输，动堆积角为20°，托辊槽角为35°时计算的。2、表中带速4.5 m/s，5.6 m/s为非标准值，一般不推荐选用。）

 2. Main technical performance parameters

       The belt speed range of this series is 0.8∽6.5m/s, among which the commonly used value is 0.8∽5.0m/s. The maximum chunkiness of materials suitable for various bandwidths is shown in Table 1, and the belt speed, bandwidth and matching capabilities are shown in Table 2. (Note: 1. The conveying capacity is calculated based on horizontal transportation, the dynamic stacking angle is 20°, and the roller groove angle is 35°. 2. The belt speed in the table is 4.5 m/s and 5.6 m/s are non-standard values. Generally not recommended.)
