Ointment for summer weather

YoungLia

Hi, 

I am trying to make simple ointment in pilot scale. Like 10-25kg per batch.

Ingredients:
Petrolatum/ Petroleum jelly
wax
water soluble solids (quite a chunky granules)

What would be the best way if I try not to use three roll mill? 
My three roll mill is too slow (small capacity) and fiddly.

Thanks in adv.

Regards,
Lia

You need a cowles dissolver or similar high-speed, high-shear disperser if you can't use a 3-roll mill:

Anything else will be either nearly impossible to clean or extremely expensive - or both.

Is this the same machine to make lotions and emulsions?
