What Is The Construction Of TSX Banana Vibrating Screen?

Banana screen is named because it looks like a banana, banana vibrating screen with a box type ZDQ series exciter is a linear vibrating screen can be used for grading, desliming, desizing, feed size 0-300 mm, can be screened large and medium size of coal, non-coal material classification. The screen plates used are slit, woven, bar, perforated and polyurethane screen plates.

 Sieve body

  1. Side plate.

Vibration excitation beam: the vibration excitation beam is of box type design, with all the main welds fully penetrated. Level I UT flaw detection and magnetic particle flaw detection shall be carried out, and heat treatment shall be carried out to eliminate welding stress. It has high strength and light weight. Before assembly, the mating surface of the exciting beam is precisely processed with a CNC machine tool, effectively ensuring the overall assembly quality of the screen machine.

  1. Lifting beam: the lifting beam is designed with round special pipe, all welds are fully penetrated, first level UT and magnetic particle flaw detection are conducted, and heat treatment is conducted to eliminate welding stress. Precision machining is carried out through a large CNC machining center.
  2. Cross beam: the cross beam is designed with round special pipes. All main welds are fully penetrated. High strength and light weight. The surface is treated with unique polyurethane spraying process, which is erosion resistant and corrosion resistant.
  3. Back plate:

Vibration system

  1. Exciter

The TSX vibration exciter adopts SKF special vibration bearing, with super large excitation force and long service life, light structure, good sealing, fast heat dissipation, low noise, convenient maintenance, durable and reliable. The swing block is equipped with a variety of plug filling methods, which can combine eccentric torque or excitation force of large variables to meet different vibration indexes and use requirements. The magnetic oil plug is used to timely absorb iron filings in gear lubricating oil, Improve the quality of grease, adopt splash lubrication method, and select world-class high-quality lubricating oil to greatly improve the service effect and life of the equipment. The vibration exciter can work normally at the temperature of – 30 ℃~+80 ℃, and is equipped with a special respirator.

  1. Intermediate shaft: an intermediate shaft is used to connect two vibrators to ensure synchronous rotation of left and right vibrators. Both ends of the intermediate shaft are connected to the vibration exciter swing block by a unique elastic rubber disc coupling. The intermediate shaft is a rigid shaft, maintenance free and without lubrication.
  2. Drive Shaft: the main drive shaft is a universal connecting shaft connecting the static installation drive mechanism and the dynamic vibrating screen body, with long service life and less maintenance.
  3. Drive Set: the driving system is composed of 4-pole three-phase motor, belt drive and secondary shaft assembly. The main motor is a new type motor with large starting torque and fast acceleration, which can make the screen machine pass through the resonance zone quickly. The selected motor has high performance index and reliable operation. The transmission mechanism adopts SPB belt transmission for speed regulation and deceleration to transmit power. The guide rail seat lead screw tension motor is used to adjust the belt tension, so that the belt can be used reasonably and has a long life. The countershaft assembly is composed of countershaft, SKF bearing, locking sleeve, labyrinth seal and open bearing seat, featuring reliable operation, long service life and convenient installation and maintenance.
  4. Spring: steel spiral spring is used between the vibrating screen body and the installation base for vibration isolation and buffering. The small spring stiffness reduces the dynamic load borne by the base, and the vibration reduction efficiency reaches more than 98%; The spring wire diameter is sufficient to make the spring more resistant to fatigue and not easy to break.

       6.The sieve plate structure has independent intellectual property rights, and the technology is leading in China. The sieve plate has a large opening rate, the screen gap is not easy to block,              the screening efficiency is high, the wear resistance service life is long, and the disassembly is convenient.
