Working Principle of Three-shaft horizontal vibrating screen

The triaxial horizontal screen works by utilizing the reciprocating rotary vibration produced by the vibrator excitation. The upper rotating weight of the vibrator makes the screen surface produce plane rotary vibration, while the lower rotating weight makes the screen surface produce cone rotary vibration, and its joint effect makes the screen surface produce compound rotary vibration. The vibration trajectory is a complex space curve. The curve is projected as a circle in the horizontal plane, and the projection in the vertical plane is an ellipse. Adjusting the excitation force of the upper and lower rotating hammers can change the amplitude. Adjusting the spatial phase angle of the upper and lower hammers can change the shape of the curve of the trajectory of the screen surface of the three-axis horizontal sieve and change the trajectory of the material on the screen surface.

Three-shaft horizontal vibrating screen FAQ

Q: What is a three-shaft horizontal vibrating screen used for?
A: It is mainly used for high-efficiency screening of bulk materials such as coal, ore, sand, gravel, and aggregates, especially in heavy-duty applications like mining and quarrying.

Q: How does a three-shaft horizontal vibrating screen work?
A: It uses three eccentric shafts with counterweights to generate a linear or elliptical vibration motion, which throws material forward along the screen deck while fine particles fall through the openings.

Q: What is the advantage of three shafts over two shafts?
A: A three-shaft design provides a more stable and adjustable vibration amplitude, better material stratification, and higher screening efficiency, especially for wet or sticky materials.

Q: Can this screen handle high moisture materials without blinding?
A: Yes. The elliptical or linear motion combined with adjustable amplitude helps reduce screen blinding, making it suitable for materials with up to 15-20% moisture content.

Q: What is the typical capacity of a three-shaft horizontal vibrating screen?
A: Capacity ranges from 50 to 800 tons per hour depending on deck size, number of decks, material density, and required cut size.

Q: How many screen decks can it have?
A: It can have one to three decks, allowing separation into two to four different size fractions in one pass.

Q: What maintenance is required for the three-shaft exciter?
A: Regular lubrication of bearings (usually every 200-500 hours), checking bolt torques, inspecting for unusual noise or vibration, and replacing worn springs or screen panels.

Q: Is it suitable for portable or mobile screening plants?
A: Yes. The compact horizontal design makes it ideal for portable plants where height clearance is limited, as it has a low profile compared to inclined screens.

Q: What is the typical vibration frequency of a three-shaft screen?
A: Frequency is usually between 700 and 1000 RPM, with an adjustable amplitude from 5 to 15 mm depending on application.

Q: How long do the bearings last in a three-shaft vibrator?
A: With proper lubrication and normal operating conditions, bearings typically last 10,000 to 20,000 hours. Heavy dust or high temperatures can reduce this life.
