Ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. This paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by another factor. The paper will propose …
Scale Up in Sizing for Grinding Mills Scale-up criterion is the net specific power consumption, i.e. the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids. For the full scale mill, specific power is multiplied by the feed rate to get the net mill power.

A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding
1. level 1. Filthy510. · 3y. Using a grinder to strip scale is for the birds. Go get a few gallons of muiriatic acid from home depot. Costs around $7.00 a gallon. If you're just doing small pieces you could use a Rubbermaid or something but of you're doing bigger pieces you'll have to figure out something bigger.
The rule of thumb for mill scale up is approximately 1-(√D/√d) where d is the diameter of the smaller mill and D the diameter of the larger mill. So going from a 12" lab scale mill to a 24" mill, 1-(√24/√12) = 0.4, so the larger mill may perform as much as 40% more efficiently.

The following are the mills used for very fine grinding. Hammer mills Hammer mills are high speed mills operating at speeds of between 2000 rpm and 6000 rpm. A set of 'hammers' rotate about a central axis in a vertical or horizontal plane. The hammers are either be fixed or are swinging freely. The whole system is enclosed in a cylindrical casing.
Scale up of agitated bead mills is possible. Sometimes, especially in the case of minimized lab equipment, a two-step scale up is necessary. The scale up method is based on the product and the mill type used. Sometimes a suitable method for a reliable scale up has to be tailor-made for the application.

For the pilot vertical mill grinding circuit simulations the parameter S1E from Table 4 must be multiplied by a factor of 1.35 in order to correct for the higher efficiency of the vertical mill relative to the tubular ball mill (Mazzinghy, 2012).
Mill scale is a leftover byproduct on hot-rolled steels, undesirable for welding. It is necessary to remove it for critical welding, but you can weld over it for simple welding projects. The fastest way to remove mill scale along the joint is with an angle grinder and a silicon carbide wheel or flap disc.
In light of the results obtained in this investigation, the current ball mill scale-up methodologies need to be suitably modified. Batch grinding experiments performed in the pilot-scale ball mills, designed to simulate the grinding environment in the production mill, can provide valuable information for carrying out this task with higher accuracy.
