linear vibrating screen for crushed ore process screening

The structural design of linear vibrating screen focuses on high rigidity, high reliability and standardized manufacturing, which is suitable for rapid screening of large quantities of materials under continuous, high-intensity working environment. Widely served in metallurgy, coal, mining, building materials, chemical industry and many other industries, and can be diversified and customized according to the needs of different working conditions.

Linear vibrating screen features:

1. A complete series of models, screen surface area from 2.25 square meters to 18 square meters, can be adapted to different output requirements.
2. The use of high-strength screen frame, good structural stability, welding process using anti-cracking treatment and heat treatment to eliminate residual stress.
3. A variety of screen mesh, can choose stainless steel slit screen, polyurethane screen or woven wire mesh, suitable for different material characteristics.
4. The screen surface angle can be adjusted from -10 degrees to +5 degrees, supporting horizontal and slightly tilted installation, to enhance the adaptability of the process.
5. Vibration motor left and right arrangement to form a synchronized linear excitation, screening effect is uniform, low noise.
6. Optional automatic lubrication system to facilitate routine maintenance and extend service life.
7. The screen machine supports the user to specify the installation direction, motor arrangement, screen type and other parameters of the customization, with good flexibility and versatility.
8. Can be used for separating the particle size 2 to 100mm grading and screening operations, such as the closed circuit screening of the crushed ore process, dewatering screening and so on.

The main advantages of linear vibrating screen:

1. Large processing capacity, a single device can achieve 756 tons of material screening per hour, suitable for large-scale screening occasions.
2. High screening precision, suitable for dry screening or wet grading of medium size and above granular materials.
3. Stable operation, reasonable vibration parameters, bearing anti-corrosion design, long service life.
4. Vibration frequency, amplitude, screen angle and other key parameters can be adjusted according to the material characteristics, adaptability.
5. Convenient maintenance, reasonable layout of the screen body, screen mesh replacement and equipment cleaning is simple and fast, reduce downtime.
6. Low noise, the use of spring vibration isolation system, equipment running on the surrounding environment with little interference.
7. High degree of structural standardization, high versatility, easy to produce, maintain and replace parts.

The working principle of linear vibrating screen:

It is mainly composed of screen body, exciter, support structure and motor. The exciter consists of two vibration motors of the same specification, installed on both sides or bottom of the screen body. After the motor is started, the synchronized linear vibration force is generated through the rotation of the eccentric block, which makes the screen body vibrate in the linear direction.

Materials from the inlet to the screen surface, under the action of vibration force forward linear jump movement, the process of particles according to the size of different levels of screen mesh to achieve classification or dewatering. Larger particles stay in the screen mesh forward discharge, small particles through the mesh into the lower level, so as to realize the particle size sorting. By adjusting the angle of the eccentric block of the vibrating motor, the size and direction of the excitation force can be changed, and then regulate the speed and trajectory of the movement of materials on the screen surface.

Typical application areas of linear vibrating screen:

1. Metallurgical industry: iron ore, manganese ore, chrome ore and other raw ore classification; sintered ore cooling screening treatment.
2. Coal industry: pre-screening and grading of raw coal; dewatering and desliming operations in coal washing plant.
3. Building materials industry: grading and screening of sand, gravel, mechanism sand and other materials; screening of raw materials for cement production line.
4. Non-metallic mining industry: kaolin, quartz sand, feldspar and other fine-grained non-metallic mineral screening.
5. Chemical industry: grading and purification of granular chemical raw materials, sieving impurities.
6. Environmental protection industry: construction waste screening and processing system, wet and dry separation in sewage treatment.
7. Transportation and water conservancy: highway bedding material screening, reservoir engineering aggregate pretreatment and other fields.
