The Factors to Affect The efficiency of vibrating screen

10-09-2012

The linear vibratory screen application is relatively universal and the advantages are also obvious. It is able to improve fine ore grade, which is usually 1.0 percent-2.5 percent, or the best even 4 percent-5 percent. It obtains a better effect in wear resistant. When operation, vibratory screen will screen out finished product at first, and then it grinds the left products with disqualification particle size. This process allocation is rational and less investment. Besides, it obtains better effect and earlier benefits.

The particle size entering into vibratory screen is key factor affecting screening effect. The more products which is up to the standard particle size in materials, the higher screening rate. And the amount of standard products depends on first stage ore grinding effect. Sometimes, overflow products enters into vibratory screen, there many reasons for that. The main reason is that the amount of ore in fist stage grinding changes, or it may be workers' mishandle. When overflow products enters into vibratory screen, operation efficiency and fine ore grade will reduced greatly. Therefore, the operators should pay more attention to it and avoid such accidents happening.The structural adjustment of vibrating screen.

vibrating screen can also select and classify powder and particle materials, widely used in plastics, abrasives, chemicals, pharmaceuticals, building materials, food, carbon, fertilizer and other industries.

In general vibratory screen is rest on horizontal ground and the vibration direction angle is 45°, under this circumstance the performance parameters of sieve machines are justice configuration, the machine will have high operation speed, high capacity and high screening efficiency. However the vibratory screen can also be placed on an angle, usually 5°or 10°according to the requirements of individual process and the special needs. vibratory screen is mainly used for fine material grading and dehydration deliming. So the too large angle may result in poor screen efficiency.

They are widely used in mining, building-material, silicate and chemical industry in the crushing and screening plants.

Working Principle Industrial ball mill Vibrating feeder consists of vibrating frame, spring, vibrator, motor vibrating device and motor. The vibrator is made of two fixed eccentric shafts whose gears are jogged. When installation, the two gears must be jogged according to the sign. Through drive of the motor, the two eccentric shafts start rotating to produce a linear huge power which forces the feeder to vibrate. Through the vibration, the materials will slip and sling on the funnel, moving forward, when the materials pass the screening part, smaller parts will fall down, and avoiding the further crushing, so screening purpose can be reached.
