Black rubber or plastic spatulas are not used in ointment compounding. If preparing a large quantity of ointment, a mixing device of some type might be used instead of the ointment slab and spatula. Two options are an ointment mill, and an "electric mortar and pestle." Ointment mills produce very smooth and elegant ointments. The electric ...

For example grinding with planetary ball mill makes a wide PSD which is not desired. I want o mill silica powder (D90=100, D10=50 micron) to fine powder (D90<10, D50<5, D10<2 micron).


1996/05/15We report data on using the emulsion-based method for the assembly of ball-like aggregates of a positively charged (amidine) latex. The latex particles are strongly hydrophobized with the use of sodium dodecyl sulfate, which induces their adsorption into the bulk of the emulsion droplets.


For some non-soluble solid flotation reagents, it can be formulated into an emulsion. For example, the solubility of lime in water is very small. We can grind the lime into a powder, and add water to make it into a milky suspension (such as Calcium hydroxide). Or it can be directly added to the ball mill as dry powder. Saponification


Flamex is a fire-resistant, water-in-oil invert-emulsion fluid for hydraulic systems such as those found in underground mining and steel mill equipment in which fire hazard and personal safety concerns require water content for fire control. Flamex is approved by FM Approvals. APPLICATIONS: Flamex is premixed and ready to use. It contains 47-50 ...

Acicular ferrite fine particles (CoFe2O4 and NiFe2O4) were prepared by using an emulsion liquid membrane (ELM, water-in-oil-in-water (W/O/W) emulsion) system, consisting of Span 83 (sorbitan sesquioleate) as the surfactant and D2EHPA (bis(2-ethylhexyl)phosphoric acid) as the extractant (cation carrier). Co2+, Ni2+, and Fe2+ were extracted from the external water phase and …


1. 4 parts volume of oil: 2 parts of water: 1 part of gum are added to prepare an initial or primary emulsion A.The acacia or other o/w emulsifier is titrated with the oil in a perfectly dry Wedgewood or porcelain mortar until thoroughly mixed.


The preparation of the emulsion satin paint is given in Table 5. Different batches of emulsion paint were formulated using various amount of core–shell latex along with TiO 2 as pigment in a standard ball mill. In all the paints, the total amount of …

This mixture was well dispersed under ultrasound (JP-030S, Jiemeng, China) for 5 min, then transferred to an all-round planetary ball mill (QM-QX2, Nanjing, China) filled with 1.2 mm ZrO 2 balls (mass ratio of ZrO 2 to pigment was 150:1). The mixture was dispersed for 10 h to get the predispersed pigment dispersion. 2.2.2.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. ...


III. Colloid Mills (CM) • Droplet disruption in colloid mills occurs in a flow channel between a rotor-stator assembly • The rotor may have a large variety of surface profiles (toothed) • Typical rotational speeds are n=3000 min-1 Due to the conical design, the emulsions is …


is dispersed. The carbon black is ground in a steel ball mill for 24-72 hours depending on the degree of jetness and dispersion desired. The organic pigments were dispersed first on a high speed dissolver and then ground in a porcelain or ceramic ball mill. The titanium dioxide was dispersed in a high speed mixer for 15-20 minutes.

• DO if possible, use warm water for dilution and always add the water slowly to the emulsion (not the emulsion to the water). • DO avoid repeated pumping and recycling, if possible, as the viscosity may drop and air may become entrained, causing the emulsion to be unstable.-Chapter Three from the Basic Asphalt Emulsion Manual.
