A.Circular vibrating screen can be divided into light and heavy type, pedestal type and hanging type, with working area of 4m2 to 14m2. The screen has novel structure, high strength, reasonable vibration parameters, fatigue resistance, long service life, simple maintenance, low noise and high screening efficiency.
It is used for screening and classification of bulk materials in coal, metallurgy, mining, building materials, chemical industry and other departments. The screen structure includes woven screen, perforated screen plate, iron plate screen plate, etc.
- B. Double shaft vibrating screen
The screen surface of the double shaft equal thickness vibrating screen (ZSD type) adopts the broken line type with different inclinations. The advantage of the equal thickness screening method is that when it is used for screening fine particles (less than 25 mm), it can reduce the screen hole blockage;
High processing capacity; The equipment is easy to configure and occupies a small workshop area. The disadvantage is large installation height. The screen can be used for dry or wet screening of medium and small particle materials such as coal, ore and ore gravel.
The linear vibrating screen has ZKX type suitable for processing large, medium and fine materials, and ZKB type suitable for dehydration, disintermediation, desliming and grading of dry or wet materials of fine materials.
C.The motion track of the screen is straight, and the screen surface is horizontally installed. The movement of materials on the screen surface does not depend on the inclination of the screen surface, but depends on the direction angle of vibration. The screen has compact structure, high strength and reasonable vibration parameters; Fatigue resistance, long service life, convenient maintenance and good reliability;
Stable vibration and low noise; The motion track of each point on the screen surface is the same, which is conducive to the screening of materials and has high screening efficiency. The disadvantages are complex structure, high manufacturing accuracy, difficult amplitude adjustment, heavy vibrator, etc.
D.Linear vibrating screen is widely used in coal preparation plants, metallurgical mines, building materials, light industry and chemical industry. In metal ore dressing plant, it is often combined with autogenous mill, gravel mill or ball mill to form closed classification, and the classification efficiency is higher than that of spiral classifier.
- E. Resonance sieve
Resonance screen is a kind of screening equipment working under resonance state. Its advantages are: large processing capacity, high screening efficiency; Compact structure and simple transmission mechanism; Stable operation, low energy consumption, easy adjustment of amplitude and frequency, and low noise.
The disadvantage is that the manufacturing and installation precision is high, and the ore feeding should be uniform and the price is high. Resonance screen is mainly used for screening, dehydration, desliming and medium removal in coal preparation plants, and also used in a few metal ore dressing plants.
