Industry:

Buildings & Structures (BSTR)

 
 

Application:

Floor Problem Areas (FPA)

 
 

Customer Location:

Aluminum Producer, MA, Brazil

 
 

Application Date:

August 2005

 
 

Application Situation:

Ball mill engine and gearbox base

 
 

Problem:

In an inspection conducted by the producer, it was found that there was a very high vibration caused by excessive gap at the base of the ball mill engine and gearbox. It was necessary to provide an effective solution for the situation not to worsen over time.

 
 

Products:

Belzona 4111 (Magma-Quartz)

Belzona 4151 (Magma-Quartz Resin)

Belzona 4911 (Magma TX-Conditioner)

 

Substrate:

Concrete (base) and carbon steel (support of anchor bolts)

 
 

Application Method:

This application was carried out based on Belzona Know-How System Leaflets FPA-10 and FPA-1. Surface was prepared through mechanical scarification. After cleaning, the surface was conditioned with Belzona 4911. After that, Belzona 4111 and Belzona 4151 were applied by injection technique. These products have excellent adhesion, vibration and compression resistance and are superior to convencional concrete in order to minimize the effects of wear (gaps) at the base of anchor bolts.

 
 

Belzona Facts:

Following data was found through vibration analysis: Before application – average vibration of 10.57 mm/s². After application – average vibration of 3.38 mm/s². Based on that, it was concluded that Belzona’s technology reduced the vibration effects on the equipment by 1/3.
