What should be paid attention to when purchasing sludge drying equipment

1. Considering from the selection of heat source

From the point of view of heat source, the selection of sludge drying equipment should also consider the local energy resources and input cost, so as to achieve reasonable utilization and reduce the cost. For example, the hot blast stove using coal and coke as heat source is economical, but the one-time investment of the hot blast stove is large, the air temperature of the hot blast stove using oil or natural gas is stable and easy to control, the one-time investment of the hot blast stove is small, but the fuel cost is high, and so on.

2. Considering from sludge drying process

According to the contact direction of hot air and materials, sludge drying equipment can be divided into: 1. Indirect drying technology, such as paddle dryer, tube bundle dryer, disc dryer, rotary dryer, steam dryer, etc. 2, direct drying, such as spray dryer, fluidized bed dryer, three level multi loop dryer. Users can choose the appropriate drying process according to their own material characteristics when purchasing equipment.

3. Considering from regional factors

Due to the temperature difference between the north and the south, the drying effect and operation cost should be considered. Otherwise, the dehydration effect is poor, the productivity is low and the drying cost is high. Therefore, the safety environment and other factors should be considered when purchasing sludge drying equipment. In addition, different regions have different economic consumption levels, different labor costs, and different prices of equipment and raw materials, resulting in different dryer prices in different regions, which also requires users to consider clearly before purchasing.

4. Considering the professionalism of the manufacturer

In order to successfully complete the drying operation, in addition to considering the drying process, heat source, environmental differences and other factors introduced above, we should also investigate the professionalism of the sludge drying equipment manufacturer, whether the reasonable equipment and auxiliary equipment are designed and matched, whether the manufacturer's spare parts are sufficient, whether the transportation after-sales service is good, etc., which are closely related to whether the dryer manufacturer is formal and reliable Off.

Generally speaking, when we purchase sludge drying equipment, we should not only choose it according to the properties of materials and the requirements for output and drying effect, but also pay attention to the material and process type of the equipment, only in this way can the drying efficiency and quality be better guaranteed, and more profits be brought to the enterprise.
