Graphite based operational highly viscous adhesive lubricant for large open running gear drives
GRAFAL OGL-2500 is based on chosen high viscous base oil, thickened with
aluminum complex soap. The product contains colloidal graphite of the highest
purity and fineness and in addition a carefully determined additive package, which
is chlorine free and contains no heavy metals, together with adhesive additives.
Applications
GRAFAL OGL-2500 is used on the spray lubrication of large gear rim drives of tube
mills, ball and rod mills, rotary kilns, dryers and crushers, which are to be found, i.a.,
in the raw materials industry or the power station sector. In addition GRAFAL OGL2500 is suitable for the lubrication of large chains, wire ropes and heavily loaded
sliding guides in rough operating conditions, e.g. in the mining and cement
industry. Further applications are found in sugar and paper production as well as in
marine and offshore technology.
