I want to upgrade my lab setup to make pigment dispersion better. I have researched several ways of doing this, and I believe a Bead Mill Machine is the best to provide an ultra-fine particle size within paint and inks. Has anybody used a Bead Mill Machine for small batches? I am primarily looking for info on how they require cleaning between color changes compared to a standard Ball Mill? Thank you!

Greetings to all! Our small entrepreneurial entity engaged in the beauty industry is attempting to broaden its offerings. As of now, all attempts at formulating using base ingredients have produced inconsistent results in terms of particle sizes. To improve our formulation process (for example, when testing formulations) with greater accuracy, we are contemplating obtaining a laboratory wet milling system prior to scaling up our manufacturing processes. Does the high cost of such a laboratory wet grinding system actually justify the time and cost savings that these systems provide over the use of traditional laboratory equipment?

Our team would like to optimize our ink production process. Currently, we are using vertical mills, however the production speed is not as fast as we would like it. I recently read about Horizontal Bead Mills and believe that they may be more efficient for continuous processing than vertical mills. Has anyone else compared the two machines?  Additionally, I want to know how easy are horizontal beadmills to clean since color changes will occur. Also, any information on daily maintenance requirements on a horizontal mill would be greatly appreciated by our team.

I am reviewing pigment dispersion process data, and I have found inconsistent discharge temperatures during wet Bead Mill operation. Have any of you experienced a strong correlation between slurry viscosity (it seems) and the effectiveness of the cooling jacket? We are trying to establish if the root cause of the inconsistency is either from insufficient mechanical seal pressure or the total energy input. I would appreciate any technical input on successfully managing residence time without overheating the product (for example, using smaller zirconium grinding media).

When purchasing a machine remember to check with the manufacturer, not just the cost, of when they will supply spare parts. In my experience, the most wear on a machine usually occurs on mechanical seals and disc grinding plates. If the machine manufacturer takes several weeks to deliver parts you will stop making products until parts arrive. You may also want to ask if lab samples of the slurry can be supplied before you purchase full production size equipment from the bead mill manufacturer.
