Electromagnetic vibrating screen for screening phosphate rock

Technical Field

The utility model relates to a phosphorus ore processing equipment technical field, concretely relates to electromagnetic vibration sieve that screens is carried out phosphorus ore.

Background

Phosphate rock is a generic term for phosphate minerals that can be economically utilized, and is an important raw material for chemical minerals. It can be used to prepare phosphate fertilizer, yellow phosphorus, phosphoric acid, phosphide and other phosphates, and can be used in medicine, food, match, dye, sugar, ceramics and national defence industries. The industrial use of phosphate rock has been known for over a hundred years.

In the processing process of phosphorite, screening is essential important step, and screening machinery commonly used includes types such as inertial vibrating screen, eccentric vibrating screen, from centering shale shaker and electromagnetic vibration sieve, and wherein the electromagnetic vibrator is the better one of screening effect. The electromagnetic vibrating screen is also called a bin wall vibrator, is flexible and convenient to use, can adjust the vibration strength at will by using a controller, and has a better using effect.

However, the existing electromagnetic vibrating screen has certain defects, and the main reason is that the electromagnetic vibrating screen can only vibrate in the direction of the magnetic force provided by the coil when working, so that unidirectional vibration can only be performed, and for part of ores with large particle size difference, more accurate screening cannot be performed, so that a better electromagnetic vibrating screen is needed.

SUMMERY OF THE UTILITY MODEL

Not enough to exist among the prior art, the utility model provides an electromagnetic vibration sieve for phosphorus ore screening for solve current electromagnetic vibration sieve can only one-way vibration, lead to the not good problem of ore screening effect that the particle size difference is big.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the electromagnetic vibrating screen for screening the phosphate ores comprises a screen box and an electromagnetic vibrating device, wherein the screen box comprises a box body and a plurality of layers of screen meshes arranged in the box body;
