horizontal vibrating screen for coal and other industries

Compared with the inclined screen machine, horizontal screen has more stable material movement trajectory and higher screening control accuracy, widely used in wet screening and dry screening system.

Structure and characteristics of horizontal vibrating screen:

1. Large excitation force box-type exciter: equipped with advanced box-type excitation device, the excitation force is strong, to ensure that the material is fully dispersed and permeable to the screen; the internal bearing adopts imported SKF or FAG high-precision products, to improve the operational stability and service life.
2. Double sealing protection: it adopts “labyrinth+mechanical” combination sealing structure, which has excellent dustproof and waterproof effect, effectively prolongs the life of bearings, and adapts to the harsh working conditions.
3. Silent design and high reliability: the whole machine structure is optimized, low noise, suitable for continuous and stable operation, reducing maintenance frequency and downtime.
4. High-strength screen frame structure: the screen body after finite element analysis to strengthen the design, the overall structural rigidity, not easy to deformation, can withstand large screening impact load.
5. Adjustable amplitude: the counterweight adjusting mechanism can flexibly control the amplitude according to the material characteristics and process requirements, and improve the screening efficiency.

The technical advantages of horizontal vibrating screen:

1. High screening efficiency: through the linear or elliptical vibration mode to promote the material uniform fabric, improve the efficiency of particles through the screen.
2. Strong adaptability to multiple working conditions: both wet materials and dry bulk materials can be adapted, suitable for coal slurry, slurry, metal tailings and other high water content material processing.
3. Low operation and maintenance cost: simple structure, easy to overhaul and maintenance, modular key components for easy replacement.
4. Energy saving and environmental protection: low energy consumption drive system, with efficient sealing technology, reduce environmental pollution and noise emissions.

The working principle of horizontal vibrating screen:

Horizontal vibrating screen produces synchronous reverse rotary motion through the exciter arranged on both sides of the screen body, forming vibration wave along the direction of the screen surface, so that the material on the screen surface is a straight line jumping forward. After feeding, large particles remain on the screen and are transported to the end to be discharged, while fine particles pass through the screen holes to complete the classification. The screen surface is generally kept close to the horizontal (inclination angle 0 degrees to 5 degrees), in order to extend the material in the screen surface residence time, so as to enhance the effect of dewatering and desliming.

Horizontal vibrating screen application fields:

1. Coal industry: used in raw coal dewatering, gangue screening, coal slurry separation and other key links, suitable for coal washing plant tailing coal dewatering system.
2. Metallurgical industry: particle size classification after ore crushing, or in wet concentrate recovery to achieve effective dehydration.
3. Non-ferrous metal mines: used in aluminum ore, iron ore, copper ore and other flotation concentrate screening, concentration and dewatering operations before drying.
4. Building materials and sand and gravel industry: used in mechanism sand, limestone, river pebbles and other materials, particle size screening and water content control.
5. Environmental protection field: dealing with sludge dewatering, tailings dry discharge and other scenes that require efficient separation of liquid-solid mixtures.
