Lubricants for Sugar Mill

Speciality Lubricants for Crusher Mill Bearing

BECHEM’s product range is adaptable to both individualised as well as centralised lubrication systems. Trials conducted in both these systems with BECHEM Berulit SM Super have shown substantial savings in consumption.

An important stage in the sugar manufacturing process is the pressing/milling process to extract juice from the cane. The crushing mill defines the capacity of a sugar mill. Rollers in the crushing mill supported by journal bearings are subjected to both heavy and shock loads and operate under slow rotational speeds of 5 to 50 RPM.

The work environment is severe as these bearings are exposed to acidic cane juice, water and also dirt-laden environments. Ideal lubrication condition for a journal bearing to perform with minimal wear is when the bearing performs at the hydrodynamic lubrication regime characterized by minimal loads and high speeds. However, journal bearings employed at a sugar-crushing unit usually operate in boundary and mixed lubrication regime due to slow speeds and heavy loads.

Why Berulit SM Super?

Understanding nuances of the sugar manufacturing process and criticality of crushing mill, BECHEM has developed the advanced lubricant, BECHEM Berulit SM Super for the journal mill bearing application.

Adaptable with Centralised and Individualised Systems. BECHEM’s product range is adaptable to both individualised as well as centralised lubrication systems. Trials conducted in both these systems with BECHEM Berulit SM Super have shown substantial savings in consumption.

Speciality Lubricants for Crusher Mill Bearing

How can we optimise lubrication consumption in Crusher mill bearings?
Journal bearings at cane crusher mills operate in boundary and mixed lubrication regime due to slow speeds and heavy loads. Traditional lubrication approach has been to continuously pump the conventional lubricant to avoid metal to metal contact between the frictional surfaces and thereby undesired wear. Additionally water is continuously pumped to reduce bearing temperatures. This approach however results in significant lubricant consumption as well as a messy shop floor.

To provide effective lubrication and thereby reduce consumption, a lubricant with high base oil viscosity that can form thick film between the shaft and sleeve and thereby reduce metal to metal contact is required.

Why should you consider Berulit SM Super for Crusher Mill bearing ?

Specially developed for high load applications, Berulit SM Super has high base oil viscosity of 2500 cSt which enables it to form a thick film between the contacting surfaces and thereby significantly minimizing wear rate of journal bearings.

Multiple field trials have proven reduction in consumption by 8 to 10 times when compared to conventional bituminous oils and by approximately 30% against low viscosity greases and high viscous oils.

Due to inherent properties of this special grease, minimal lubrication is sufficient to maintain the ideal bearing temperature. This also eliminates the need for external cooling of bearing and also reduces loads on ETP.

How does shock loads impact mill bearings? Can lubricants mitigate its impact?

Due to the nature of operation, shock loads on mill bearings are unavoidable in the crushing area. Conventional lubricants that are unable to withstand such extreme pressures, ooze out under these conditions allowing the contact surfaces to absorb the impact. Repeated impact of such loads might result in burn marks and cracks in the bearing. Lubricants with good EP properties can help mitigate the affect of shock loads on the bearings.

The special additive package along with high base oil viscosity, equips Berulit SM Super with a high load carrying capacity of over 8000 N. Additionally solid lubricants as additives, provide emergency lubrication properties and thereby guards bearing from critical loading conditions.

How to avoid abrasive damage to the shaft ?

Conventional greases are thick and have a tendency to hold onto contaminants during regular crushing operations leading to abrasive wear on the shaft and sleeve. An ideal lubricant for the crushing mill application should not only be able with withstand high loads but also possess good flushing and pumping properties.

Berulit SM Super is a fluid grease with excellent flushing property. Additionally, the fluid grease based on special metal soap thickener that has superior pumping properties in comparison to other thickeners has excellent flow-ability and pump-ability. This avoids choking of lubrication lines and points and any undesired damage to bearing by line choking and lubricant run-out.
