The Tianhe Environmental Protection Roller Shaft Screen is mainly available in two series: the XGJ series with single-axis independent drive, and the XGJLW series with multi-stage linked operation. It is suitable for coarse-to-fine separation of various mineral materials such as coal, coke, ore, and limestone, and is currently a widely adopted coal-screening device in China’s coal-handling systems. It is also extensively used in metallurgical, chemical, and building-materials industries.

Tianhe Environmental Protection Roller Shaft Screen They are mainly categorized into the XGJ series of single-axis independent drive units and the XGJLW series of multi-stage linked drive units, which are suitable for coarse-to-fine separation applications involving coal, coke, ores, limestone, and other types of mineral materials. These screening units are currently widely adopted in China’s coal-handling systems and are also extensively used in metallurgical, chemical, and building-materials industries.
The function of the roller-axis screen is to separate fine particles from the feed material before it enters the crushing system, thereby reducing the load on the crusher, improving crushing efficiency, minimizing wasted energy consumption, and increasing the overall production capacity of the system.
The axle spacing and screen-disc gap of the roller-axis screen determine the particle size of the material being screened; therefore, its configuration offers a very broad range of options. Users can select the appropriate configuration based on factors such as the material’s composition, the proportion of fines passing through the screen, and the screening efficiency. When paired with a variable-frequency drive system, the rotational speed of the screen discs can be adjusted in real time according to operating conditions, thereby achieving optimal separation performance.
