Sand making equipments mainly include impact crusher, jaw crusher,hammer crusher,cone crusher and vibrating feeder,etc.Henan Hongxing professionally specializes in the production of sieve and linear vibrating screen.
The advantages of vibrating screen:
It is mainly composed of screen box, exciter, suspension (or support) device and motor. The machine drives exciter spindle rotate via V-belt, due to the unbalanced centrifugal force of inertia of the weights on the exciter, screen box can vibrate. Changing the exciter eccentric weight can obtain different amplitude. The main advantage of vibrating screen:
1. Strong vibration of the screen box reduces the material clogging, sieve has high screening efficiency and productivity.
2. The structure is simple and convenient, and there is replaceable screen surface.
3. The power consumption of screening materials is far less than before.
Mechanical structure of vibrating screen
Vibrating screen is generally composed of vibrator, screen box, supporting or suspension, transmission components.
The vibrator of uniaxial vibrating screen and biaxial vibrating screen can be divided into two kinds based on eccentric reconfiguration.
The sieve boxes:
The sieve box is composed of screen frame and screen surface and the clamping device. The screen frame is constituted by the side panels and beams. The sieve box must have sufficient rigidity.
The supporting device :
The supporting device vibrating screen hanging seat. Seat installation is relatively simple, and low installation height, which should generally be preferred. Vibration sieve support device is composed mainly by the elastic element, it is commonly used with a helical spring, plate spring, and a rubber spring.
The vibrating screen usually adopts belt transmission device, the vibrating screen structure is simple, the number of revolutions of the vibrator can be arbitrarily selected, but the running belt is easy to slip, which may lead to the sieve clogging. Vibrating screen can be driven directly by couplings.
The coupling can maintain the stability of the vibrator, and long service life, but the number of revolutions of the vibrator has adjustment difficulties.
