Disc Screen Topic

The disc screen is an efficient screening equipment. It can achieve accurate separation of materials of different sizes and shapes through the rolling motion of precisely designed discs. The equipment has the characteristics of strong processing capacity, high screening efficiency, small footprint and low energy consumption, making it the preferred equipment in modern waste treatment facilities. The modular design of the disc screen makes the equipment maintenance and operation more convenient. Users can flexibly choose the number of discs according to actual sorting needs to achieve rapid adjustment of the equipment. At the same time, the disc screen is also equipped with an intelligent variable frequency drive system, which uses variable frequency stepless speed control technology to further reduce energy consumption and improve operational safety. The equipment is widely used in the pretreatment of various types of solid waste such as domestic waste, construction and decoration waste, and stale waste, and has made important contributions to urban environmental sanitation and sustainable development. In short, the disc screen has a wide range of application prospects in the field of screening equipment with its unique structure and excellent performance.

The disc screen is mainly used for various solid wastes, such as domestic waste, building decoration waste, stale waste, kitchen waste, etc. It can crush fine particles in domestic waste, facilitate subsequent processing, and entangle flexible materials, especially materials that cannot be separated by drum screens and vibrating screens. It is not easy to separate stones and wet soil when mixed together. Difficult separation does not mean that it cannot be separated. There is such a device, which is the nemesis of stone and mud stone separation.

Disk Screen

The disc screen machine can also be used alone or in conjunction with various sand and gravel production lines to separate mud and stone well. This equipment can replace the vibrating feeder. While separating wet soil, it can realize the function of the feeder, so that the material entering the crusher is basically large stones, with almost no excess soil. In this way, the efficiency of the crusher is not only greatly improved, but also the crusher is prevented from various failures caused by soil mixing.

The disc screen machine can be selected according to the user's production scale. The equipment can achieve the expected output by increasing or decreasing roller separation according to the output. The butterfly screening machine uses a motor to drive the drum to move regularly, and the disc configured on the drum promotes the advancement of materials. The spacing between the rollers is adjusted to determine the size of the separated material. The box can also be equipped with a ventilator to dry the wet material. This is why the disc screen separates mud and stone. The use of a mud and stone separator can solve some problems in mining. At the same time, it can also be a good substitute for the drum screen and vibrating screen to double the processing efficiency.

The principle of the disc screen is mainly based on the rotation of the material, centrifugal force and gravity for screening.

The disc screen is a rotary screening device that screens granular materials according to particle size through the screen. During the screening process, the force will project the material onto the screen surface, and then the material will be crushed by the screen and sorted by gravity to achieve the purpose of screening.

The disc screen is mainly composed of a motor, a reducer, a screen, a material inlet and outlet, and a screen machine body. During operation, the motor drives the reducer to rotate, driving the entire screen machine to rotate. After the material is put into the material inlet, due to the action of centrifugal force, the material will continue to rotate along the disc and be projected onto the screen surface. Large particles of material will be rejected above the screen surface due to inertia, and small particles of material will fall on the bottom of the screen through the screen holes. After multiple screenings, materials with similar particle sizes are finally separated.

1. Structural composition: The disc screen is usually composed of a screen drum, a screen, a motor, a reducer and a bracket. The screen drum is the main part, and the screen is the key component of screening, usually woven with metal wire.

2. Working principle: The motor and reducer provide power to rotate the screen drum. The material enters the screen drum through the feed port. Due to the rotation of the screen drum and the action of the screen, the material is evenly distributed on the screen.

Screening process:

a. The rotating screen will generate a certain centrifugal force. The material is acted upon by the centrifugal force on the screen, causing the particles to move outwards close to the screen, thereby improving the screening effect.

b. Gravity is also one of the main forces for material screening. Gravity pushes larger particles to the outside of the screen. These particles cannot pass through the pores of the screen and are retained on the screen.

c. Smaller particles can pass through the pores of the screen and enter the discharge port below to achieve screening.
