In early 26th, our company officially signed a supply agreement for Disc Screen with the client for a large open-pit coal mine. After two months of intense production and strict testing, along with subsequent logistics transportation, the batch of equipment successfully arrived at the customer's designated location on March 2, 2026.

The customer reported that during the transportation of the equipment, its overall appearance remained intact without any bumps or damages. At present, the entire batch of equipment has been transported to the project site. Once the on-site conditions are met, professional technicians will be immediately arranged to install and debug it.

During the in-depth communication in the early stage of the project, the client clearly put forward the core performance requirements for the Disc Screen: the processed material is raw coal that has not been washed and selected, the equipment production capacity needs to stably reach more than 1,600 tons per hour, the feed particle size is 80mm, and the particle size of the material under the screen needs to be strictly controlled within 20mm.

Based on the specific working conditions and screening requirements provided by the customer, our technical team attached great importance to them and organized engineers to conduct multiple rounds of parameter calculation and simulation verification. Eventually, a scientific and reasonable design plan was determined: The width of the Disc Screen screen surface is set at 2200mm. A total of 35 high-strength screen shafts are configured. The designed operating speed of the screen shafts is 77 revolutions per minute. The overall installation inclination Angle is set at 10° to ensure that the screening efficiency and processing capacity perfectly match the customer's requirements.

Due to the strong wet and sticky nature of raw coal itself, if traditional vibrating screens are used for screening, it is very likely that the screen holes will be blocked due to material adhesion. This not only significantly reduces the screening efficiency but also makes subsequent cleaning and maintenance very difficult.

Disc Screen performs outstandingly in terms of anti-clogging: Its multiple parallel arranged screen shafts rotate in the same direction, constantly stirring and rolling the materials, which can effectively break up the clumped wet coal and prevent the screen gaps from getting clogged. Meanwhile, the equipment is equipped with an advanced self-cleaning device under the screen, which can remove the sticky materials adhering to the surface of the screen shaft in real time, ensuring that the screen shaft remains in a clean and efficient working state continuously, and greatly enhancing the reliability and service life of the equipment.
