The Wobbler Feeder is a high-performance screening equipment designed to provide reliable separation and smooth material conveying.
It is composed of multiple rotating shafts equipped with heavy-duty discs or rollers, which create a large active screening area to handle bulk materials effectively and continuously. This configuration ensures accurate classification and stable throughput across a wide range of applications.
Also known as Wobble Feeder or Disc Screen, the Wobbler Feeder demonstrates strong adaptability to wet, sticky, or irregular materials.
Compared with conventional vibrating screens, it minimizes the risk of plugging and blinding, thereby maintaining efficiency, consistent feed, and superior screening results even under demanding working conditions.
Due to its robust design and outstanding performance, our Wobbler Feeder s are widely used in coal preparation, mining, cement, metallurgy, and chemical industries.
With their long service life, reduced downtime, and low maintenance needs, they deliver excellent operational reliability and economic benefits to customers.
How Wobbler Feeder Work?
The screening area consists of many parallel arranged roller shafts, the screen shaft is equipped with a number of staggered screen discs, the roller shafts rotate in the same direction, to realize the feeding and screen of materials.
The Screen surface of Wobbler Feeder is composed of several parallel arranged screen shafts equipped with shaped screen discs, and the screen shafts are driven by the Driving device to rotate in the same direction at the same speed, forming a rolling screen surface.
When the material flows on the screen surface, it can form a material flow of equal thickness and with a certain acceleration.
The gap between the screen shaft and the screen disc forms the screen hole, the material less than the screen hole is subjected to its own gravity and the rotating force of the screen shaft, and becomes the material under the screen through the screen holes. Material larger than the screen holes continues to enter along the screen surface under the action of the rotating screen disc, becoming the material on the screen, and finally achieving the classification of the material.
Wobbler Feeder Core Components
Our company has skilled technical workers and perfect quality management system, to ensure the high quality of the core components of the Wobbler Feeder , to provide a guarantee for the high-performance operation of the product.
Screen Shaft Assembly
The screen shaft assembly is composed of motor + reducer, screen shaft, screen disc, flat key, locking nut, coupling, bearing seat and bearing seat accessories. The drive motor is connected with the reducer and screen shaft through the coupling.
The design of the screen shaft is reasonable and safe, which can effectively avoid the phenomenon of bending and breaking of the roller shaft.
When any group of screen shafts fails, the material can continue to move forward under the push of previous screen shaft, and the screening can operate as usual. The screen shaft bearing seat is installed on the outside of the screen box side plate for easy disassembly.
Screen Disc
The screen disc is made by casting a wear-resistant manganese-chromium alloy steel as a whole, which has excellent wear resistance. It can withstand the impact and wear of large pieces of materials and will not undergo any deformation or fracture.
The screen disc is designed as a parabolic sieve plate shape and is rounded to eliminate sharp corners, minimizing the rotational resistance of the sieve plate.
The parabolic screen disc can maximize the disturbance ability of the roller screen disc on the material flow and improve the screening rate.
Wobbler Feeder Details
Drive Device
It adopts single-axis single-motor drive or multi-axis chain combination transmission mode, reasonable power configuration and screen surface structure to evenly distribute the material load in the screen and ensure smooth operation.
The design structure of the driving device is simple, easy to install and disassemble, and the connected screen shaft is not moved when disassembling.
The driving device is compact in size, light in weight, long in life and low in maintenance cost.
Screen Disc
Wobbler Feeder disc with staggered layout, more reasonable design. Wobbler Feeder disc has good impact resistance and will not appear any deformation and fracture phenomenon.
Wobbler Feeder disc has good wear resistance and long service life. The parabolic shape screen disc has reasonable design and high assembly accuracy, which can improve the screening accuracy.
Screen Box
The main body of the Wobbler Feeder is welded with low-alloy high-strength structural steel. All screen shaft assemblies are fixed to the machine body through connecting bolts. Wear-resistant lining plates are installed on the side of the machine body to avoid direct contact between materials and the box, greatly extending the service life of the equipment. And the wear-resistant lining plate and the screen box are connected by bolts, which is easy to replace.
Protective Housing
The protective housing of the Wobbler Feeder is welded with NM500 wear-resistant alloy steel plate, sprayed with anti-rust and anti-corrosion paint, and connected with the hopper and the outlet housing at the front and back.
The overall sealing of the screen box can effectively prevent dust pollution, reduce the impact on the environment, and meet the requirements of green construction.
The protective housing is provided with an observation window to facilitate the observation of the operation of the machine.
Wear-Resistant Lining Plate
The wear-resistant lining plate is made of alloy material, and the whole production process adopts welding, heat treatment, machining and other assembly line production, which has a long service life and strong wear resistance, toughness and impact resistance.
The inside of the screen box and the contact surface between the guide groove and the material are provided with wear-resistant lining plates, which can protect the screen box and increase the life of the guide groove. The lining plate is fixed together with the mother plate by bolts, and the replacement is convenient.
Self-cleaning Device
The self-cleaning device of the screen shaft is made of wear-resistant steel and is equipped with a cutting edge, which is inclined to the lower part of the screen shaft. Some fibrous debris and sticky materials attached to the screen will be automatically cleaned off by the cleaning device to solve the blockage of the screen surface.
Wobbler Feeder Features

Why Choose Wobbler Feeder?
Wobbler Feeder VS conventional screens, have the following advantages.
Wobbler Feeder s distinctly outclass conventional screens, especially in the case of difficult to screen, wet, sticky bulk materials, feeding and screening is distinctly outclass to conventional screens, which often exhibit baking and sticking with these materials.
Wobbler Feeder operate with low energy consumption and low profile requirements, and without vibration, noise or transmitted stresses, making them ideal for both stationary and portable applications.
Compared with the traditional screen that uses vibration to separate materials, the Wobbler Feeder does not vibrate, the equipment is relatively strong, does not require frequent maintenance and overhaul, and the overall life of the equipment is longer.
