Frequently Asked Questions
What materials can be sieved through a GALAXY SIVTEK screener?
GALAXY SIVTEK serve almost every industry dealing with powders and liquids. We have application data for both wet and dry screening applications ranging from very coarse to 350 mesh (40 microns) product applications. Materials such as paper pulp, paper coatings, sugar syrup, sugar granules, ceramic powders, ceramic slurries, toner, food, pharmaceuticals, metal powders, effluent and many others are being run on GALAXY SIVTEK screeners with a wide variation in particle size and characteristics. If you would like to test your material, your regional technical representative or agent can be contacted to run a test in GALAXY SIVTEK Test Centre.
How can we determine what screening machine is needed for our product and capacity?
Our extensive application list based on hundreds of applications usually provides us with enough information to specify a suitable unit. However, sometimes, it is necessary for your local technical representative or agent to visit you and have technical discussions with your technical team to suggest a suitable unit for your application.
After material runs through the screener for a while, the capacity falls off. How can we keep our capacity constant?
This condition is caused by the screen blocking or blinding with material getting stuck into the individual holes of the mesh. The solution is to fit our anti-blinding unit with discs and/or balls. This unit is used in most of the cases. However, it sometimes may be required to go for an advanced technique like Ultrasonic Attachments.
The screen cloth near the outer ring or near the center is tearing on my Circular Vibro Separator. Is this due to a poor-quality cloth?
Yes, it could be if the good quality mesh is not being used. Other causes could be overloading of the screen or allowing the abrasive material to stay on the screen cloth too long before it is ejected. Better control of feed to the machine and optimized settings of the machine will help in these cases.
The material on the screen is moving around in the wrong direction. Why is this happening?
This will occur when the motor wiring is connected incorrectly. Check the wiring instructions in the Technical manual and direction of running of the motor.
Once the motor direction has been checked you can fine tune the pattern of material on the screen by changing the weight settings. Information on this can also be found in the technical manual for the machine. If you do not have our manual or have misplaced it, call us to obtain a fresh copy.
The de-blinding discs/balls in my machine are wearing out quicker than usual. Why is this happening?
Has your product changed? Have the properties of your material changed? This could result in the balls/discs wearing out more quickly. You should also make sure that you are using genuine Galaxy Sivtek balls/discs which will give maximum life. Please provide Galaxy Sivtek full details of your product so that they can select the most appropriate material for the balls/discs to maximize their life for your product.
The screening efficiency of Vibro screen is found reduced since last few days?
Either the Wire mesh cloth fitted on the screen ring frame has become Loose and the mesh tension is reduced, or you may have selected the wrong opening wire cloth while re-fixing the screen cloth.
How can we increase the output capacity without going for the bigger size of the machine or going for an additional vibro screen?
If your Machine is more than 1 year old, you can go for Retro-Fit Kit from Galaxy Sivtek which can improve your output capacity by approximately 20% – 30%. Alternately you can go for adding MAXIMIZER Deck on your existing machine to get additional 50% – 60% capacity on the same machine.
Is it observed that sieve decks are getting cracked near outlet spout on a frequent basis?
Ensure that you have not tied any firm element with outlet spout. Ensure that no heavy load is being kept on outlet Spout. Use only Galaxy Sivtek Flexible Connectors to connect outlet spout with collecting device. Do not keep any material or load on outlet spout.
