How to choose the material of heavy metal sludge dryer

With the continuous development of industrial economy, all kinds of sludge production is also increasing. In order to solve the problem of large quantities of high moisture and high viscosity metal sludge treatment, heavy metal sludge dryer is loved by many enterprises in the drying market. The material of heavy metal sludge dryer equipment is mainly steel. The quality of equipment material directly affects the durability and service life of the equipment. So how should users choose the material of heavy metal sludge dryer equipment?

1. High temperature resistance

In the process of sludge drying, the principle of heat and mass transfer between high temperature hot air and wet sludge is mainly used in the heavy metal sludge dryer, so the cylinder is always kept at high temperature when the dryer is running. This requires users to pay attention to materials with good high temperature resistance when selecting equipment materials, so as to keep the equipment working stably for a long time and avoid deformation or damage of cylinder due to high temperature.

2. Friction resistance

During the operation of the heavy metal sludge dryer, with the continuous rotation of the cylinder, plus the dispersing device and lifting device set in the cylinder, the materials in the cylinder are constantly stirred and lifted, resulting in frequent friction between the materials and the cylinder. In order to avoid the wear of the cylinder after long-term friction, users need to pay attention to the wear resistance of the materials when purchasing equipment materials Yes.

3. Thermal insulation performance

The cylinder material with good thermal insulation performance can ensure sufficient heat and relatively stable temperature in the cylinder to avoid excessive temperature loss, so the quality of thermal insulation performance also affects the drying efficiency and quality of materials. When choosing the material of equipment, users need to choose the material with thermal insulation performance, which can not only prevent the loss of heat, but also improve the utilization rate of heat energy and reduce the heat loss in the drying process.
