Some Methods of Cleaning Stainless Steel Vibrating Sieve

Stainless steel vibration sieve 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 sieve.
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.
I hope you can get some useful information.

Troubleshooting for Gyratory Screen

As one of our main product, gyratory screen has been supplied to many plants all over the world and also enjoys a good reputation because of its superior design and quality. Gyratory screen is widely applicable to chemical, food processing, refractory materials, building materials, activated carbon, food, PVC powder and other fine materials.
However, during the operation, we may meet some problems, here PK Machinery will introduce the breakdown reason and method in detail. 

BreakdownReasonSolution

The bearing cup is not compatible with other parts
Belt is too tight
Overload working for a long time
Change the grease
Change bearing
Correct the main shaft
Change the part which coordinate with the bearing
Adjust the tightness of the V-belt
Reduce the feeding rate
There is no force for motor
Two phase electricity
Circle short for the winding
Overload working for a long time
Power on the lost phase electricity to ensure it runs under 3 phases
Inspect the motor
Keep the screen working under the rated load
Fail to start the motorLow voltage
Electrical wiring is too thin
Fuse is broken
Start the screen once electricity is normal
Change the electrical wiring
Change a proper fuse
Violent or wiggly vibrationThe rotation shaft bends
Bearing is broken
Replace or correct the shaft
Replace the bearing
The unqualified size material mixed in the finished materialScreen mesh is broken
Screen cover or seal bar is loose
Renew the screen mesh
Press the cover and seal bar
Capacity decliningThe moisture is too high, block the mesh
The opening size is not suitable
Rotation speed is low or the V-belt is loose

An Earthquake Material of Equipment-----Vibrating Platform

Vibrating/Shaking Platform is the device mainly used for reducing air and crannies among the material to compress the material; it is always used with silo.Is it good for your company? Do you want to have a try?
Vibration Platform is widely used in steel, foundries, concrete, food processing, plastics, construction, chemical and bulk materials industry. If you own such an equipment, it will bring you a great surprise!

►  Working Principle

Unbalance motors make the platform to oscillate. An oscillation insulating elastic suspension connects the top and bottom part of the platform. The amplitude of the oscillation can be changed by adjusting the unbalances on the unbalance motors during standstill. Besides, the vibration frequency can be changed during the operation time if an electric control with frequency inverter is being used. Both parameter have influence on the vibration intensity and allow an adaption to the different scopes. 

►  Features

Analysis of field application of starch vibrating screen extension

 As the name suggests, vibrating screen is used for the separation,classification and sorting of starch. And the main equipment is rotary vibration screen.
The advantages are as follows:


1.The mesh number of material with screened is small that can achieve micro powder sieving. There is dust cover in the top layer so that can prevent the dust, protect environment and improve the working environment of workers.

2.Outlet of the machine can be adjusted the direction within the scope of 360 degrees in a horizontal plane based on the axis in the center of the screening equipment.

3.Screen machine has low energy consumption and can save resources.

The reasons and preventive measures of blocking of vibrating screen

It is a common problem that vibrating screen will appear the phenomenon of blockage of sieve.There are many reasons that cause the blockage of sieve.The reasons are as follows:
 
1.Physical reasons:Many granules are close to separation point; the water content
of material is high; it will happen the phenomenon of static electricity.

2.Material factors:The material is fibrous; there are many flake-like material.
vibrating screen mesh

3.Sieve desigh:The hole shape design is unreasonable which isn’t meeting the requirements; the silk to weave sieve is too thick.
Measures to solve the blockage of sieve
1.Control the water content of material:When the water content of material is more than 5% and there is no any other methods to dry the material, it should select proper screen surface and sieve mesh; if the water content of materialis more than 8%, it should adopt dewatering screen to meet our needs.

2.Classify material:Before screening more flake-like material, what we should do is chaging the way to crush material; if the material size is small and it contains more pelitic material, we need to pay much attention to water content.
