What reasons lead to linear vibrating screen motor base crack ?

All users know that the vibration motor is the vibration source of linear vibrating screen , it will bring inconvenience of operation if the vibration motor base cracks and damages. Here are some analysis reasons for you:
1. Too large motor power ,model selection and exciting force which exceed the normal load of vibrating screen, it will cause damage of motor base for long time operation
2. Too thin steel plate thickness design with long time operation will cause crack.
3. There is a problem with steel plate material.
4. Welding quality can not meet the requirements.
5. The installation position of the motor does not conform to the design requirements of the vibration dynamic specifications.

What Screen is Used in the Feed Industry--the Gyrotary Screen

At present, most feed manufacturers need to sieve and grade the powder material ,granular feed, and the intermediate products after secondary crushing. The quality and output of the feed products are directly affected by the classification and the performance of the equipment. What screen is commonly used in the feed industry? The answer is the gyrotary screen. It is widely used in feed industry due to its simple structure, large output, convenient maintenance, low noise.
Under the inertia force, gyrotary screen sieve box moves back and forth, driving the screen surface shaking periodically, and forcing feed material on the screen surface jumps along with the screen box, the material which is less than sieve aperture will be discharged from the outlet after continuous rolling and jumping movement, then screening operations complete.

 

Gyrotary screen is a new type of high efficiency swing type linear screening equipment ,and also called square swing sieve, it can completely solve the screening accuracy and processing output contradiction of general vibration screening machine, see the following characteristics:
1.Reasonable design, mature technology, easy installation and maintenance, wide application scope;
2.High screening efficiency , precision and processing capacity;
3.Unique design, convenient screen mesh replacing, high utilization rate, long service life;
4.Good screen mesh self-cleaning effect is good, low noise;
5.Good sealing effect, energy saving and environmental protection.

Besides, gyrotary screen can be used in chemical, metallurgy, ceramics, non-ferrous metals, non-ferrous metals, non-ferrous metals, food, food, abrasive, mining and other industries in the accurate screening and grading process. Specific application materials, for example, chemical industry: chemical fertilizer, resin, melamine, soda ash ; Food industry :starch, salt, sugar, milk powder and other; metallurgy, non non-ferrous metals, nonferrous metal, magnetic materials.

How to Make Vibrating Screen Look Clean without Stainless Steel?

Stainless steel vibrating screen will become matt if they are used for a long time, when screening materials with chemical reactions (such as corrosion) ,there would be a passivation film on the surface, it will exist steadily as a shape of the oxide in the nature. In other words, though stainless steel working conditions and oxidation are not the same, they will be oxidized in the end, this phenomenon is often called corrosion. The metal which is exposed in the corrosive environment, it will produce electro-chemical or chemical reaction on the surface of metal, even corrode. Corrosion resistance abilities of vibrating sieve passivation film are weak, due to stress caused by pitting corrosion reactions, it will generate small holes, coupled with the approach of chloridion, it will form a strong corrosive solution, which will accelerate the corrosion reaction rate, as well as the corrosion cracking inside the vibrating sieve, all of these will have a destructive effect on the surface of the stainless steel vibrating screen .
Therefore, stainless steel surface needs cleaning and maintenance punctually, especially in the corrosive environment to ensure its beautiful surface and extend the use life. It is necessary to pay more attention to not scratch the surface during cleaning, and please avoid cleaning the surface by using liquid bleaching composition or abrasives, steel wool and abrasive stuff, in order to clean up the washing liquid, please clean it with water again after finishing scrubbing the surface.

Introduction of Dewatering Screen

Have you felt very confused with wet materials put in the bag or other places?Today our dewatering screen will help you!
Dewatering screens have a wide variety of application including dewatering, desliming, degritting, rinsing, scrubbing and washing. It is made up of screen cloth, vibration exciter, supporting system and motor. Materials such as sand, gravel, crushed aggregates, frac sand, industrial sands, mineral sands, hard rock, precious metals, coal, iron ore, salt and other granular materials which can be processed through a dewatering screen.
 

dewatering screen

To dewater material effectively, damp material is feed onto a steep, downward inclined screen surface at the feed end of the Dewatering Screen to achieve rapid drainage. A pool of water begins to form in the valley as material builds up on the slightly upward inclined surface. Counter rotating motors create a linear motion, driving solids uphill, while liquid drains through the screen media. The uphill slope of the screen, along with a discharge weir, creates a deep bed that acts as a filter medium, allowing retention of material much finer than the screen openings.
When the two vibrating motor that installed vertically on the coal dewatering screen rotate relatively, the eccentric block of two vibrating motors produce rated excitation force. The horizontal excitation force cancel each other out, the vertical excitation force is transported to the whole screen surface through the body mass vibration.

Introduction of Circular Vibrating Screen

Circular Vibrating Screen is a kind of new and highly effective vibrating screen that does circular vibrations and has multiple layers. Circular vibrating screen adopts cylinder postures eccentric block to produce strong exciting force. Its main body is connected by high strength screw bolts. A circular, elliptical vibration motion is created in order to sieve the materials efficiently. It is composed of screen box, screen mesh cloth, suspension (or support) device, underframe and motor.

► Working principle
Circular vibrating screen separator uses eccentric block(YK type)/eccentric shaft(YA type) to produce strong exciting force, due to the unbalanced centrifugal force of inertia of the weights on the exciter, screen box vibrates, it can obtain different amplitudes by changing the exciter eccentric weight.
