What is an ointment mill used for?
What is an ointment mill used for?
An ointment mill utilizes high shear force to reduce particle sizes, disperse agglomerates, and homogenize viscous materials. Shear force is created by three horizontally positioned rollers rotating in opposite directions and at different speeds relative to each other.
What is roller mill principle?
Roller mills use the process of stress (which is applied by the rotating wheels) and attrition in milling of solids in suspensions, pastes or ointments, and some solid materials. The rollers rotate at different speeds and the material is sheared as it passes through the gap.
What is the working principle of triple mill?
A three roll mill or triple roll mill is a machine that uses shear force created by three horizontally positioned rolls rotating in opposite directions and different speeds relative to each other, in order to mix, refine, disperse, or homogenize viscous materials fed into it.
What is the product size in roller mill?
The roller mill minimizes such costs by precisely reducing feed materials with an average particle size up to 3⁄4 inch to a uniform average size typically between 100 and 2,000 microns.
How do you clean ointment mills?
Cleaning the ointment mill is performed by turning off the unit, spraying alcohol on a paper towel, and manually turning the rollers while wiping them clean. Substance processed with conventional mixing procedure show crystalline substances that are still clearly visible.
What is an ointment slab?
The Glass Ointment Slab is a clean smooth preparation area which eliminates cross contamination. The heavy weight glass square provides a hard nonporous surface for incorporating compounds into ointment bases. The roughened bottom minimizes movement. The glass is a 100% non-absorbable surface for mixing.
What is the minimum speed of ball mill?
Mills operating below 75 rpm are known as low-speed mills. Low-speed units include ball or tube or drum mills, which normally rotate at about 15–25 rpm.
What is the difference between hammer mill and roller mill?
The difference between a roller mill and a hammer mill is: A hammer mill uses rotating hammers to pound grain through a screen and it requires a lot of horsepower. A roller mill uses cylindrical rollers that grind the grain when it goes through them, which requires less horsepower then a similar capacity hammer mill.
What is a four high rolling mill?
Rolling mill consisting of four rolls or known as a 4 High rolling mill is used for reducing material to extremely small thicknesses. Through the use of larger backup rolls, the issues of roll deflection can be avoided and smaller work rolls can be used.

How do you clean an Exakt ointment mill?
CLEANING YOUR EXAKT OINTMENT MILL create larger pores in the porcelain. cleanser or baking soda. You can put a little on a damp sponge and spot clean with it gently. remove that residue with alcohol before running a new product.
What is an ointment mill and how does it work?
An ointment mill utilizes high shear force to reduce particle sizes, disperse agglomerates, and homogenize viscous materials. Shear force is created by three horizontally positioned rollers rotating in opposite directions and at different speeds relative to each other.
What is an opointment mill?
Ointment mills produce very smooth and elegant ointments. The electric mortar and pestle allows the formulation of the ointment and the dispensing of the formulation to be done in the same container. (Photos courtesy of Professional Compounding Centers of America, Inc., Houston, Texas)
What is the difference between an ointment mill and mortar and pestle?
Two options are an ointment mill, and an “electric mortar and pestle.”. Ointment mills produce very smooth and elegant ointments. The electric mortar and pestle allows the formulation of the ointment and the dispensing of the formulation to be done in the same container.
What do you use to mix ointment?
An ointment slab (left) and large metal spatulas should be used for this process. Ointment slabs are either ground glass plates or porcelain and provide a hard, nonabsorbable surface for mixing. Ointment pads (right) have the advantage that “clean-up” is quicker, but the ointment can soak into the parchment paper.
