Comparison of Circular Vibro Sifter and Linear Vibrating Screen
There are many kinds of vibration screens, which can be pided into circular vibro sifter and linear vibration screens according to their trajectories. These two kinds of vibration screens are widely used in daily life screening equipment. This paper is a comparative analysis between circular vibration screen and linear vibration screen, aiming at providing users with a comparative reference in choosing these two kinds of equipment.
In view of the difference between circular vibro sifter and linear vibration screen, we summarize the following four points for you:
Material comparison
Generally speaking, the plates of circular vibro sifter are thicker when it is made. In order to resist the impact of materials in the screening process, most of the boxes are made of manganese steel.
The linear vibration screen is mainly made of light carbon steel or 304 stainless steel.
Contrast of applicable fields
Circular vibrating screen is mainly used for screening materials with large proportion, large particle size and high hardness (such as coal, ore, etc.), which are widely used in coal preparation, mineral processing, building materials, electric power and chemical industry.
The linear vibrating screen is mainly used for screening fine materials, light weight and low hardness materials. It is widely used in food, chemical, metallurgical, pharmaceutical and other industries.
Comparisons of processing capacity
Circular vibro sifter is a mine screening equipment with large capacity and processing capacity of 80-620 t/h. It can be customized according to the different output requirements of users.
As a fine screening equipment, the processing capacity of linear vibrating screen is generally 0.12-20 t/h. Different types of linear vibrating screen and different screening materials have different processing capacity.
Contrast of working principles
The vibrator of the circular vibro sifter is installed on the side plate of the screen box, and the motor drives the rotation through the coupling, which generates centrifugal inertia force and forces the screen box to vibrate. The adjustment of the inclination angle of the screen surface can be realized by changing the position and height of the spring support. There are perforated sieve plate and rubber sieve plate, there are two kinds of single-layer and double-layer sieve plate, all kinds of sieve plate can conceal the requirements of high screening efficiency, long service life and non-blocking holes. The motor can be flexibly installed on the left or right side of the screen frame.
The linear vibrao sifter uses two vibrating motors to rotate backward, which makes the exciter produce reverse exciting force and drives the screen box to move forward and backward in a straight line. When the material enters the screen box from the inlet port at one end, it is evenly distributed on the screen surface. Under the combined force of exciting force and material self-weight, the material is thrown up on the screen surface and jumps to the outlet port. At last, the sieving and grading of materials are realized through the sieving screen with different aperture sizes. The material is discharged from the corresponding outlet of each layer, thus completing the whole sieving process.
