Vibrating screen can be classified in a variety of ways, including inclined screens for aggregate and linerar vibariang screen according to the motion track of materials, both of which are commonly used as screening equipment in daily production of sand and gravel fields. inclined screens for aggregate is widely used in the field of mine crushing. In actual production, inclined screens for aggregate or linerar vibariang screen mainly depends on the type of materials handled by the user and the application field. Therefore, different screening purposes will lead to different equipment selection. inclined screens for aggregate and linerar vibariang screen are not intrinsically different in style and structure composition. Both materials are inclined screens for the purpose of screening through the vibration of screen surface, but the different vibration tracks will directly affect the purpose of screening.
Working principle:
inclined screens for aggregate:
The motor is driven by the triangular belt to make the shaker eccentric block produce high-speed rotation, produce a great deal of centrifugal inertia force, stimulate the screen box to produce a certain amplitude of circular motion, the screen material on the inclined screen surface by the screen box impulse and produce continuous throwing motion, the material and screen surface meet in the process of less than sieve particles through the screen, so as to achieve classification.
linerar vibariang screen:
The use of vibration motor excitation as the vibration source, so that the material is thrown up on the screen, at the same time for linear motion forward, the material from the feeder evenly into the screen machine feed port, through the multi-layer screen to produce several specifications of the screen, screen, respectively from the respective outlet discharge.
Inclined screens for aggregate and linerar vibariang screen are not intrinsically different. Both materials are inclined screens for aggregate based on linear motion formed by screen surface vibration. But the different vibration trajectory will directly affect the purpose of screening, so the user's selection is particularly important, so the user should know more about the two kinds of equipment to avoid the loss of selection errors.
Inclined screens for aggregate is the excitation force generated by the vibration of the shaker driven by the general motor through a soft connection to achieve the purpose of screening,inclined screens for aggregate makes the material on the screen surface is parabolic circular track movement, so that the material as far as possible to disperse so as to improve the material jumping force to reduce the phenomenon of plugging,inclined screens for aggregate is mainly used for material with heavy screening ratio, large particle size and high hardness. It is the most widely used in mining industry such as mine, coal and quarrying plant. inclined screens for aggregate have a higher inclination to the ground than linerar vibariang because the material moves on the screen surface for a little longer The screen Angle should be large, for the purpose of improving the screening efficiency of materials, and the inclined screens for aggregate will not be too strict in the screening accuracy under the premise of not affecting the screening accuracy aggregate is usually made with a thicker plate and the box must be made of manganese steel to resist the impact of materials during screening.
The linerar vibariang screen consists of two vibrating motors mounted on the lower part of the body, with inclined screens for the screen aggregate is on the contrary, because the eccentric block of vibration motor is smaller, the vibration frequency is higher, and the amplitude height of the material on the screen surface is lower, so the movement time of the material on the screen surface is shorter, and there is basically no Angle between the screen surface and the ground during production. linerar vibariang screen is mainly used to screen materials with fine particles, light specific gravity and low hardness, which are usually the most widely used in food, chemical, building materials and pharmaceutical industries.linerar vibariang screen is mainly made of light plate or stainless steel plate, which is relatively inclined screens for aggregate vary greatly in weight, amplitude, and efficiency.
The main differences between the two are:
1. Motion trajectory
Inclined screens for aggregate materials move in circles, while those on linerar vibariang screen move in straight lines.
2. vibrator
Inclined screens for aggregate because vibrator is a shaft, the use of inertia motor work, so it is also called single shaft vibrator, linerar vibariang screen vibrator is composed of two shafts, using the principle of vibration motor excitation work, so it is also called double shaft vibrator.
3. Hole plugging phenomenon
Inclined screens for aggregate materials move in a parabolic circular trajectory on the screen surface, so that the material can be dispersed as much as possible to improve the material jumping force, and the material stuck in the screen can also jump out, reducing the phenomenon of hole blocking.
4. Installation layout
The linerar vibariang screen reduces the height of the screen due to the small inclination of the screen surface, which facilitates the process layout.
5. Inclination Angle of screen surface
According to the particle size of the material, inclined screens for aggregate can change the inclination Angle of the screen surface, so as to change the movement speed of the material along the screen surface and improve the processing capacity of the screen machine. In general, the linerar vibariang screen has a low inclination in production.
Step 6: Material
In general, inclined screens for aggregate production uses thicker plates, and the box is made of manganese steel, in order to resist the impact of materials in the screening process. linerar vibariang screen is made of light or stainless steel plates.
7. Field of application
Inclined screens for aggregate Main inclined screens for aggregate materials with high screening ratio, large particles and high hardness are widely used in mining, coal, quarrying and other mining industries. linerar vibariang screen mainly screens fine particles, light specific gravity, not high hardness of materials, mainly dry powder, fine particles or micro powder materials, usually in food, chemical, building materials, pharmaceutical industry is widely used.
8. Processing power
Inclined screens for aggregate, because the shaker is arranged above the center of gravity of the screen box, the long axis of the ellipse at both ends of the screen box is shaped in the lower eight shape, and the upper end of the long axis of the ellipse at the feeding end is towards the direction of discharge, which is conducive to the rapid spread of materials, while the upper end of the long axis of the ellipse at the discharge end is against the direction of discharge, reducing the speed of material movement. It is beneficial to the difficult screening material through screening, and the circular arc screen surface increases the effective area of the screening machine, so as to improve its processing capacity.
In addition, for difficult screening materials, inclined screens for aggregate can make the spindle turn over, so that the vibration direction is opposite to the movement direction of the material, and the movement speed of the material along the screen surface is reduced (when the inclination Angle of the screen surface is the same as the rotation speed of the spindle), so as to improve the screening efficiency.
