1. Introduction of equipment

Rotary steam tube dryer (RSTD) is a kind of indirect-heated rotary dryer. The difference against the normal rotary dryer is that the former has steam tubes installed in the cylinder. The tubes are arranged in concentric rows, extend the full length of the shell and supply the heat for drying. This dryer is heat-conduct type equipment. There are atmospheric type and gas -tight type. The later is suitable for combustible and explosive situation. According to drying process requirement, there are counter-current type and co-current type. By the character of product, either powered or unpowered discharge screw can be chose for material feed and discharge.

The dryer is mainly comprised of shell, steam chest, heat exchange tubes, support rollers, driving unit, feed/discharge side seal, feed/discharge framework, etc. Through constant development and perfection. Now we have achieved a variety of product design and manufacturing, and also obtained a number of patent.

2. Features of the dryer

This dryer has following features

High heat transfer coefficient and high thermal efficiencyLarge treatment capability, wide applicationWell drying effectIndirect-heating, no material contaminationRetention time can be adjusted, low energy consumptionConvenient operation and easy maintenanceGas-tight type for explosive-proof situation

3. Specifications and models

According to diameter, there are 800mm-4800mm series, length from 3m to 39m. Construction material can be carbon steel, 304L, 316L and duplex. Customized design is also available.

4. Application

Rotary Steam Tube Dryer is widely used to drying products such as HDPE, terphthalic acid (PTA and CTA), ABS synthetic resin, aluminum hydroxide, pentaerythritol, copper concentrate, coal moisture control, brown coal in petrochemical, light industries, metallurgy etc.

            Adhering to take the market demand as guiding, the high-tech as foudation, and the high quality product as target, the company always keeps track of the international development trend in the fields of drying, baking,and gravity blending, and constanty upgrades the related equipments,so it has accumulated and possessed a group of high-tech products transformed from the great scientific achievements.Customization equipments can be developed according to users`requirements for meeting the demand of different product manufacture.
