The wobbler feeder crusher (also known as roller screen or disc screen) is a screening equipment that separates and grades materials through the rotation of multiple parallel screening shafts. It is widely used in industries such as coal, mining, metallurgy, construction materials, power, and environmental protection (such as construction waste treatment).
How Wobbler Feeder Crusher Work?
- Since the sieve shafts are arranged at different working angles, when the material runs at a high working angle, the speed is faster;
- when the material runs at a low working angle, the speed is slower.
- At the intersection point of a certain position on the sieve surface, the materials with different rotational speeds start to move axially, allowing the materials to be evenly distributed on the sieve surface, achieving the purpose of improving the screening efficiency.
Wobbler Feeder Crusher 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 crusher, 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 wobbler feeder disc on the material flow and improve the screening rate.
Wobbler Feeder Crusher Final Products
Our wobbler feeder crusher can efficiently screen a variety of granular materials. The applicable material discharge particle size range is 8mm to 200mm. The screening range is wide and the classification accuracy is high. It can meet the screening processing requirements for fine materials, medium materials and coarse materials under different working conditions, and is suitable for material classification operations in various industries such as mining, building materials and metallurgy.
Wobbler Feeder Crusher 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
The wobbler feeder crusher disc is arranged in an alternating pattern, which makes the design more reasonable and resistant to impact. There will be no deformation or fracture at all.
The parabolic-shaped screen disc is well-designed, with high assembly accuracy. It can increase the screening rate and improve the screening accuracy. It has excellent wear resistance and a long service life.
Screen Box
The main body of the wobbler feeder crusher 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 crusher 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 Crusher Features
It has a large processing capacity and high screening efficiency, making it particularly suitable for industrial scenarios involving continuous operations. It adopts an independent transmission system with one shaft per drive, and in case of a single shaft failure, it can bypass operation without affecting the overall production.
It can handle various types of materials, including wet materials, viscous materials, and dirty and impure materials, and is not prone to clogging. The sieve hole size (usually within the range of 25-120mm) can be customized according to requirements.
The structure is relatively simple. The wear-prone parts such as the sieve shaft and screen disc can be easily replaced, reducing the operation and maintenance costs. The drive device is external, facilitating maintenance and repair.
Smooth operation, no strong vibration, low impact on ground dynamic loads, low noise. The sealing structure can effectively control the leakage of dust.
Key components such as the screen disc are usually cast from wear-resistant materials like high manganese steel and alloy steel, ensuring a long service life.

Why Choose Wobbler Feeder Crusher?
Wobbler feeder crusher VS conventional screens, have the following advantages.
Wobbler feeder crushers 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 crusher 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 crusher does not vibrate, the equipment is relatively strong, does not require frequent maintenance and overhaul, and the overall life of the equipment is longer.
Wobbler feeder crusher are self-cleaning and designed to resist clogging and reduce blinding. They also feature an automatic lubrication system and a jog reverse function to quickly and easily solve any jamming situation.
Wobbler feeder crusher can be fed by an apron feeder or directly via trucks or loaders. No other equipment is required to assist the feeding, reducing the cost of civil construction and equipment.
