A. Specific application of vibrating screen in various types of garbage screening

Vibrating screen

1. Urban domestic waste screening

The composition of urban domestic waste is complex, including kitchen waste, paper, plastic, glass, metal and other substances. The vibrating screen can control the movement speed and screening efficiency of the material on the screen surface by adjusting the inclination angle of the screen surface and the size of the exciting force, thereby realizing the accurate screening of urban domestic waste.

a. Pre-screening treatment: As a pre-screening equipment, the vibrating screen can quickly and effectively separate large and small materials in the garbage, providing convenience for subsequent processing.

b. Classification treatment: Through the screening effect of the vibrating screen, different types of garbage can be separated, such as paper, plastic, metal, etc., providing a basis for subsequent classification and resource utilization.

2. Screening of construction waste

Construction waste includes slag, crushed stone, waste mortar, mud, waste plastic and other materials. Vibrating screen plays an important role in the screening of construction waste. It can well separate materials of different particle sizes in construction waste and meet the screening needs of different particle sizes.

a. Good screening effect: Linear vibrating screen can realize the accurate screening of materials of different particle sizes in construction waste, providing reliable guarantee for subsequent resource utilization.

b. Wide range of application: It is suitable for screening various materials in construction waste, which helps to screen these materials of different specifications and recycle them for secondary use.

c. Convenient to move: Linear vibrating screen is very suitable for mobile operation due to its simple structure and light weight, and is suitable for the needs of non-fixed places in the recycling of construction waste.

C. Application and development of environmentally friendly vibrating screens in garbage screening

With the continuous improvement of environmental awareness and the continuous advancement of technology, environmentally friendly vibrating screens have been widely used and developed in the garbage screening industry. The environmentally friendly vibrating screen adopts advanced sealing structure and dust removal technology, which effectively reduces the flying of dust during the screening process; at the same time, it pays attention to noise control, creating a more comfortable working environment for operators.

1. Characteristics of environmentally friendly vibrating screen

a. Good dust removal effect: Environmentally friendly vibrating screen adopts advanced dust removal technology. Through unloading air bags, unloading air windows or equipped dust collectors, the positive pressure airflow generated during the screening process is filtered and discharged, so that the air pressure inside and outside the screen machine is balanced or even negative pressure is generated, thereby achieving zero or extremely low dust emission.

b. Noise control: Environmentally friendly vibrating screens effectively reduce the noise level during equipment operation by optimizing vibration sources, using shock-absorbing devices and sound insulation materials, creating a more comfortable working environment for operators.

c. Energy saving and high efficiency: Environmentally friendly vibrating screens use high-efficiency motors, optimize screening parameters and reduce invalid energy consumption, which reduces the overall energy consumption of the equipment. At the same time, its efficient screening capacity also improves production efficiency and product quality.
