The vibrating sieve is a screening device developed to solve the deep screening of wet adhesive materials. Especially for the screening of wet adhesive materials of less than 10 mm, the screen blocking problem is better solved. The vibrating sieve is suitable for industries such as coal classification, electric power, metallurgy (granular classification). The vibrating screen is mainly divided into the linear vibrating screen, the circular vibrating screen, and a high-frequency screen.
The single-axis vibrating screen uses a single unbalanced heavy excitation to vibrate the screen box, and the screen surface is inclined. The moving track of the screen box is generally circular or elliptical. The two-axis vibrating shaker is a double unbalanced heavy excitation using synchronous counter-rotating, the screen surface is horizontally inclined or inclined, and the movement path of the screen box is a straight line. It has an inertial screener, an eccentric shaker, a self-centering vibrating screen, and an electromagnetic vibrating screen.
Longding YA series circular vibrating screen adopts cylindrical eccentric shaft exciter and partial block to adjust amplitude, material sieve line length, screening specifications, reliable structure, strong excitation force, high screening efficiency, and low vibration noise. Sturdy and durable, easy to maintain, safe to use, etc., the vibrating screen is widely used in product classification in mining, building materials, transportation, energy, chemical, and other industries. Long Ding circular vibratory sieve can be used for screening coal, limestone, gravel, gravel, metal or non-metallic ore and other materials.
Large processing capacity and high screening efficiency.
The vibrator is lubricated with bearing thin oil and external block eccentric structure. It has the characteristics of large excitation force, small bearing load, low temperature, and low noise. (The bearing temperature rise is less than 35°).
The whole disassembly and assembly of the vibrator are convenient for maintenance and replacement, which greatly shortens the maintenance period. (It takes only 1 to 2 hours to change the vibrator).
The side plate of the sieve machine adopts the whole plate cold work, no welding, high strength, and long service life. The connection between the beam and the side plates is made of torsion-resistant high-strength bolts, and there is no welding and the beams are easy to replace.
The sieve machine adopts rubber spring to reduce vibration and has the advantages of small noise, long service life, stable over-common vibration zone and small dynamic load of each branch of the sieve machine.
The motor and the vibration exciter are connected by a flexible coupling, which has the advantages of long service life and a small impact on the motor.
