What is A Rotary Screen Bucket? How does it work?

The Rotary Screen Bucket is a multifunctional working device installed on the excavator’s arm. Its core structure includes a wear-resistant manganese steel sieve bucket with customizable apertures and a hydraulically driven rotating mechanism. When working, the bucket rotates to cause the material to tumble, achieving screening and grading of materials smaller than the sieve holes and retention of materials larger than the sieve holes. It also has auxiliary functions such as loading and mixing.

Relying on the mobility of the excavator, it is extremely flexible and does not require the material to be transported to a fixed screening point, which can save transportation and site costs. The rotation speed is adjustable and is suitable for a variety of materials such as sand, gravel, construction waste, and ore. It is widely used in scenes such as building demolition, mine primary selection, and river dredging. It is a key equipment for improving the efficiency of bulk material processing.

What are the advantages of Rotary Screen Bucket?

1. Special design with reliable protective covers: All hydraulic parts are protected by a closed structure, and process holes are opened at the corresponding positions to ensure the convenience of maintenance.

2. High wear resistance steel with good performance: Lower after-sales service. 12 months warranty.

3. Work underwater: Imported motor, better sealing, can make the machine work stably even under water. Longer service time.

4. Customized sizes meet different requirements. Screens can be customized: Sieve stones 10-50 mm; Sand washing 2-10 mm; 80-100 mm for mines.

How to select Rotary Screen Bucket?

You can use the table below to preliminarily determine the appropriate model according to the tonnage of your excavator.

Of course, in order to better confirm the matching model, you need to confirm the excavator model, excavator age, project conditions, stone hardness, etc.

Installation of Rotary Screen Bucket

Operation Precautions of Rotary Screen Bucket

The final user has to make sure that the total weight of the load (weight of the bucket + weight of loaded material + coupling + any optional accessories) does not exceed the arm lifting capacity of the operating machine indicated in its manual; this check must be carried out for all positions with which you can operate.
The final user has to verify that the overturning capacity of the operating machine is suited for using the screening bucket; this check must be carried out for all positions with which you can operate.
To verify if your operating machines satisfy the minimum requirements, it is very important to contact the manufacturer/distributor.
Driving the operating machine to start the equipment must be carried out exclusively by a competent and skilled adult, duly trained in driving site equipment.
The activation command of the bucket can be a switch or a pedal, as long as it maintains action. To start the bucket, it is mandatory to keep the command pushed; to stop the bucket, it is enough to release the command.
The activation command of the bucket can be a switch or a pedal, as long as it maintains action. To start the bucket, it is mandatory to keep the command pushed; to stop the bucket, it is enough to release the command.
The machine must be equipped with an emergency stop command capable of stopping all screening bucket movements as quickly as possible.
Make sure the operator has fully understood the meaning of all commands and their operation.
The operator has to be familiar with and apply the safety conditions for using the machine in the workplace, in compliance with the laws in force in the user’s country.
In reference to: right side, left side, front part, and rear part, this refers to the view from the driver’s seat of the excavator.
The operator has to be familiar with and properly interpret all indications contained in the instructions manual and the signs affixed to the machine: this will help prevent damage to people, property, and the operating machine.
It is absolutely mandatory to abide by the instructions contained in the Operating and Maintenance Manual and with general EC accident-prevention standards, as well as with the national standards in force in the user’s country.
Always use the personal protection equipment required by directives EEC 89/686 and EEC 89/656; moreover, always do as instructed in the manual and according to the laws of the Country where the machine is operating.
Carefully read all the information printed on the adhesive labels concerning safety affixed to the machine.
The operator has to avoid using the Screening Bucket under unsuitable conditions or when under the influence of alcohol or drugs.
It is important to organize the worksite to carry out the lowest number of operations consistent with the job to be carried out.
To safeguard the workers’ health and safety, it is advisable to set up the worksite to be able to position the excavator at a higher level compared to the material to be crushed; by doing so, the load radius is reduced, and you avoid reaching the maximum working radius configuration.
For use on excavators, it is recommended to refrain from carrying out the bucket loading phase with the carriage laterally (see figure below on the right); this results in less stability compared to the carriage being positioned straight (see figure below on the left).
For installation on wheeled excavators, it is mandatory to secure the stabilizers or the blade (if equipped) to the ground before you hook up and lift the equipment.
For installation on operating machines other than wheeled or tracked excavators, please keep in mind all the indications provided above and below for proper operation and to safeguard workers’ health and safety.
