Sludge dryer is one professional drying equipment produced by the mining machinery manufacturers, which can be used in processing some materials such as sludge, magnetic ores, concentrate ores of metal and non-metal, the clay of cement industry and other industries. The main features of this machine are higher working efficiency, reasonable structure, significant design, higher production capacity, simple operation. The Application of Sludge Dryer This machine can be widely used in the activated sludge drying, sewage sludge drying, petrochemical sludge drying, paper making sludge drying, printing and dyeing sludge drying, tanning sludge drying, municipal sludge drying and some materials with high moisture. Our products advantages: 1.Reasonable partition can make the effect of materials dispersion become better. 2.The unique arch breaker and shaking device can effectively solve the problems including feeding device bonded, agglomeration and movement blocked in the drying process. 3.Taking the downstream craftsmanship of materials and heat flow can keep the origin of the materials. 4.Optimizing the structure design, prolonging the lifespan. Sludge dryer is mainly compose of driving device, supporting roller, thrust roller, cylinder, kiln inlet, kiln outlet and sealing device. 1. 2-3 supporting points can guarantee the contacting surface between supporting roller and tyre is paralleled with axis line of cylinder during installation. 2. Supporting device is antifriction bearing (occasionally uses slide bearing). This design has simplified the supporting device of supporting roller, and reduced the useless power loss during operation. It has the features like easy operation and maintenance. 3. Suitable shim between tire and shell will ensure the tire ring on the shell tightly to increase the shell strength. 4. The main driving system uses new type AC variable frequency technology. Compared with electromagnetic speed control and DC speed control, that can save energy, have large range & high precision of speed regulation, high efficiency and running smoothly. 5. Radial direction contacting type sealing device is adopted at kiln inlet and outlet. They are perfect suitable for dimension tolerance of cylinder and skewing movement of cylinder. This sealing device’s feature is good performance, longer working life and easy for replacement.
