Mining Trommel

Luoyang Yujie Industry&Trade Co., Ltd is one of the most experienced manufacturers and suppliers of mining trommel in China. Please feel free to buy cheap mining trommel for sale here from our factory. All customized products are with high quality and competitive price.

Mining trommels are basic screening equipment suitable for various mines. They are simple and durable, mainly composed of drums, drive mechanisms, supports, and replaceable screens. The rotating drums efficiently separate materials of different particle sizes, and the screen aperture can be adjusted as needed. Their core application is post-mining material processing, including raw coal grading and ore screening. They can also be used for impurity removal and screening of qualified raw materials before mineral processing. Suitable for coal mines, metal mines, and other types of mines, they effectively improve subsequent production efficiency and reduce material waste.

The manufacturing of a Mining trommel is a systematic and interconnected process, with each step closely linked to ensure the equipment's durability and operational stability. The specific manufacturing process is as follows:

First, thorough pre-manufacturing preparation is crucial. Based on the specific conditions of mining operations (such as the materials being processed, the intensity of work, and ambient humidity), detailed equipment blueprints are drawn up, clearly defining the dimensions, specifications, and technical parameters of each component. Simultaneously, suitable manufacturing materials are precisely selected. Core materials include wear-resistant steel plates, high-strength screen mesh, and seamless steel pipes, laying the foundation for subsequent manufacturing.

Second, the selected raw materials undergo preliminary processing. Through precise processes such as cutting and bending, wear-resistant steel plates and seamless steel pipes are processed into core components such as the drum body, flanges, and equipment frame. This ensures that the dimensional errors of each component are controlled within acceptable limits to meet subsequent assembly requirements.

Next, the core components undergo meticulous processing and reinforcement: the processed sheet metal is rolled and welded to form the drum body. After welding, strict coaxial alignment is performed to ensure concentricity during drum rotation. Subsequently, the flange is fully welded to the drum body to further strengthen its structural strength and prevent deformation or loosening during operation.

Next, the screen and frame are installed: the screen is made of perforated or woven mesh with excellent wear resistance and is securely fixed to the drum body with pressure bolts, ensuring the screen is flat and secure to prevent material jamming during operation. Simultaneously, the frame profiles are cut and assembled, then welded, followed by aging treatment to effectively eliminate internal stress and improve frame stability and service life.

Finally, the entire machine is assembled, including the bearing housing, the processed drum, the transmission mechanism, and the sealing cover. During assembly, the drum's levelness and rotational clearance are carefully adjusted to ensure smooth operation without jamming or friction, guaranteeing stable equipment operation.

After assembly, surface treatment and performance testing are performed: First, the entire machine undergoes rust removal and sandblasting to remove the surface oxide layer and impurities. Then, a wear-resistant and anti-corrosion coating is applied to enhance the equipment's corrosion and wear resistance, adapting it to the harsh working environment of mines. Following this, a no-load operation test is conducted, focusing on key indicators such as vibration amplitude, operating noise, and drum concentricity.

Finally, only after the no-load operation test is fully passed and all indicators meet design standards can the complete mining drum screen be manufactured and approved for shipment, ensuring that the equipment can be stably and efficiently put into mining operations after delivery.
