Introduction and Product Features of Finger Screens

In the treatment of decoration waste, Finger Screens can accurately classify materials such as concrete blocks, ceramic tile fragments, plastics, metals, etc., ensuring that each material can be reasonably recycled and reused. Below, the editor of Zhongcheng Machinery will introduce the basic knowledge of Finger Screens, the product structure of Finger Screens, the working principle of Finger Screens, and the advantages of Zhongcheng Machinery Finger Screens.

A.Introduction to Finger Screens:

Rod sieve is mainly used in industries such as garbage sorting, metallurgy, coal, etc. for material washing, screening, grading, etc. A new structural pattern sieve plate with various sizes and mesh sizes of rod vibrating screens, especially suitable for applications with strong impact, high hardness, and high wear resistance requirements.

The Finger Screens product adopts a feeding surface in the form of blind plates and bar bars. The bar type vibrating screen is suitable for uniform feeding of large blocks of materials in front of the crusher, and is particularly suitable for garbage sorting. It is used for feeding black or non-ferrous metal ores, building stones before coarse or medium crushing; The gap between the bars of the bar type vibrating screen is adjustable, which can separate soil and fine materials while feeding, and play the role of a crusher in the later stage; Rod type vibrating screen has the characteristics of simple structure, easy maintenance, high strength, impact resistance, wear resistance, and low noise.

B.Structure of Finger Screens Product:

The rod type vibrating screen product is mainly composed of a vibration source (vibration motor), a body, a damping spring, front and rear brackets, etc.

1. Rod sieve vibration motor is a new type of exciter that integrates power source and vibration source, with high energy saving, large excitation force, reliable use, and simple adjustment; Features such as easy use and maintenance.

2. Rod type vibrating screen body: made of welded plates and profiles, its function is to transport the material to the crusher through vibration.

3. Rod type vibrating screen damping spring: Generally, metal coil spring or rubber spring is used, which is used to generate elastic vibration of the machine body and reduce the transmission of vibration load to the foundation or structural frame.

4. Rod type vibrating screen bracket: made of welded plates, its function is to support the machine body.

C. Working principle of Finger Screens:

When the bar screen is working, the excitation force generated by the exciter is transmitted to the screen surface inside the screen box through the screen box. As the excitation force generated by the exciter is longitudinal force, it forces the screen box to drive the screen surface to undergo longitudinal forward and backward displacement. Under certain conditions, the material on the sieve surface of the rod vibrating screen is thrown forward due to the excitation force. When the material falls below the sieve hole, it passes through the screen and falls to the lower layer. The motion trajectory of the material on the sieve surface of the rod vibrating screen is a parabolic motion. Due to this repetitive motion of the material, the rod vibrating screen completes the material screening operation.

D. What are the advantages of the bar screen produced by Zhongcheng Machinery?

1. The bar screen has a simple and compact structure, beautiful appearance, and high overall rigidity and strength of each part; Relatively small in size and light in weight, convenient for system process layout.

2. With a large processing capacity, low energy consumption, and less likely to clog holes, Finger Screens are particularly suitable for screening materials with high moisture content and high viscosity. Suitable for industries such as garbage sorting, coal, mining, metallurgy, building materials, power, water conservancy, light industry, and chemical industry, for the grading treatment of block shaped and small to medium-sized particle materials.

3. The equipment is mature and complete, with complete models and specifications, and easy installation

4. Combined with the application and extension in garbage sorting, mining, and coal industries, its design is more mature and perfect, with strong excitation force, high screening efficiency, low noise, and economical use.

5. The Finger Screens has two structural forms: open and closed, which are suitable for different working environment requirements. The screen surface has single-layer and multi-layer structural forms, and the running trajectory has two forms: straight line and circle. There are various models and specifications.

6. Easy installation and debugging, stable and reliable operation, and easy operation and maintenance; There are two voltage options for the power supply of the bar screen: 380V and 660V. When selecting, please confirm the voltage system and whether there are explosion-proof requirements.

As a key equipment for precise sorting of decoration waste, the Finger Screens not only optimizes the waste treatment process, but also lays the foundation for the high price recycling of resources. Its application is an important part of achieving the reduction, resource utilization, and harmlessness of construction and decoration waste, and has profound significance for promoting the development of circular economy. With the continuous advancement of technology and the increasing awareness of environmental protection, Finger Screens will play a greater role in the future field of resource recycling.
