Compared with the high precision, high efficiency and high universality of the circular vibrating sieve, the straight vibrating sieve is more of a “warranty for fast and rough sieving of powder with less impurities and larger particles. The role of "staff", commonly used in flour, starch, washing powder and other large particles

等等。 Unlike heavy-duty screening equipment for mining, light-duty screening equipment has obvious characteristics of small volume and finer. Therefore, considering the miniaturization of equipment installation space, light-duty screening equipment is often made into a circular shape, like Similar to rotary vibrating screen (circular vibrating screen), swing screen, 450 filter, in -line vibrating screen and so on. However, it is precisely for this reason that many customers who have been in contact with the vibration screening machine for the first time have little understanding of various circular screening equipment, and they cannot distinguish between their respective differences and differences in the application process, let alone the basis. Choose the right model for your screening needs. For this reason, we have already carefully explained the differences between the rotary vibrating screen and the 450 filter, the difference between the circular vibrating screen and the swinging screen. Today we will carefully introduce the in-line vibrating screen and the common circular vibrating screen. Differences between machines.

The difference and difference between circular vibrating screening machine and in-line vibrating screen

(金禾机械)主要也从这几点作为切入点为大家区分两种外观相似、应用不同的振动筛。 When introducing the differences between the swing sieve and the rotary vibrating screen, we mainly used the starting point from the aspects of working principle, sieving accuracy, applicable materials, fuselage configuration, and sieving efficiency. The key parameters of this screening and impurity removal equipment are also the signature data of a vibration screening machine that is different from other screening equipment. Therefore, when discussing the difference between a circular vibration screening machine and an inline screen, the vibration screening The machine manufacturer (Jinhe Machinery) mainly uses these points as an entry point to distinguish two types of vibrating screens with similar appearance and different applications.

1. The working principle of circular vibrating screening machine and in-line vibrating screen are different

Comparing the structure diagram of the circular vibration screening machine and the in-line screen in the figure below, we know that both rely on the excitation force provided by the vibration motor to screen the power source, but the installation position of the vibration motor is completely different, naturally The movement trajectories of the driving materials on the sieve surface are also different, that is, the working principle of sieving is different.

The vibration motor of the in-line vibrating screen is installed on the side of the screen. It is divided into two types of single vibration source and double vibration source according to the number of motors. The movement track of the material on the screen surface of the single-vibration screen is up and down. It has the function of automatic material discharge; and the double vibration source straight-line vibrating screen drives the material to perform elliptical motion on the screen surface under the combined action of two vibration motors, and realizes the material separation and sieving process quickly and reciprocally.

The circular vibration screening machine uses the unbalanced weight of the vibration motor to generate horizontal, vertical and inclined three-dimensional motion, thereby driving the material to achieve high-precision material screening and classification.

2. Screening output is different for inline sieve and rotary sieve

Due to the difference in the setting of the discharge opening, the discharge opening of the straight-line sieve is located directly below the sieve surface, that is, the direct discharge discharge method is used, so the material is conveyed to the discharge opening during the screening and discharge process. The discharge time greatly improves the output of the in-line vibrating screen.

The circular vibrating screen is mostly considered for the screening accuracy. After the material is made to conform to the three-dimensional motion on the screen, it will continue to bounce to the side of the 360 ° rotatable discharge port under the driving of the exciting force to discharge smoothly , So the difference between the two is not small in terms of output,

According to the research of the vibration screening machine manufacturer (Jinhe Machinery): the output of the straight screen is 2-5 times that of the rotary screen.

3. The screening accuracy of circular vibrating screening machine and straight vibrating screen is different

The screening fineness of the vibration screening machine has a direct relationship with the residence time of the material on the screen surface. Because the straight-line screen adopts a direct discharge discharge method, the movement of the material on the screen surface is mostly up and down. Therefore, this type of sieving equipment is not mainly responsible for the accurate screening of materials. The sieving mesh number is about 80 meshes, which is mainly used to remove large impurities or sieving loose powder such as flour.

作为常见的高精度的广泛性筛分设备,生产商和客户对其筛分的精细度要求就高得多了,虽不及超声波振动筛,但是旋振筛(圆形振动筛选机)的筛分精度范围也可达500目左右。 As a common high-precision screening equipment, circular vibratory screening machines require much higher precision of screening by manufacturers and customers. Although not as good as ultrasonic vibrating screens, rotary vibrating screens (circular vibrating screens) Screening machine) also has a screening accuracy range of about 500 mesh.

After the above comparison, it is not difficult to find that compared with the high precision, high efficiency and high universality of the circular vibrating screen, the straight vibrating screen is more powdery with less impurities and larger particles. The role of the "quality assurance officer" for fast and rough sieving of materials is commonly used in the removal of thread and sieving of large particles of flour, starch, washing powder and other large particles. It does not undertake fine grading, which is the circular vibration. The fundamental difference in screening machines is now. It is precisely for this reason that we can often see on the circular vibration screening machine or other circular screening equipment similar to bouncing balls, ultrasonic waves, brushes and other cleaning devices that help to screen and prevent clogging. The row vibrating screen does not require any form of net cleaning device because of the large particle size of the screened material.
