COLLOIDAL MILL
Colloid mill is a machine that is used to reduce the particle size of a solid.
It is mainly reduces the solids which are present n the suspensions or emulsions or the reduction the droplet size in the suspensions. It is almost used for the all types of materials for the reduction.
Collidal mills
HISTORY
The Rolls Royce of Mixers the high shear colloidal mixer as used by Team Mixing Technologies, is the leading colloidal mixer in the industry by most grouting experts world-wide.
High-shear colloidal mixers are internationally recognized as the most efficient method of mixing cement-based grouts and other materials. Colloidal mixing results in very stable mixes which resist bleed and water contamination.
The invention concerns a colloid mill in which the material to be treated mixed with mill bodies,
It is an aim of this invention to avoid these inconveniences by the fact that the sieve or filter rotates, the sieve or filter openings being provided on the circumference of a separator device. All the above mentioned disadvantages of mills can be avoided in this way.
DESCRIPTION
The colloidal mill is used in the reduction of the particles or solid materials which are present in the suspensions or emulsion.
The shearing is the mechanism in the colloidal mill. By the stator and the rotor present in the cylindrical vessel of the colloidal mill the shearing take place and the reduction of the particles takes place.
BASIC PARTS, CONSTRUCTION, PRINCIPLE AND WORKING OF THE COLLOIDAL MILL
Basic parts
It consists of an inlet hopper which is used to feed the material into the mill.
It consists of a rotor and stator which are used to reduce the particles size by applying the shearing force.
It consists of an outlet which is ...

...or products of high viscosity range.
Capable of operation under pressures up to 16 bar.
High-value seal with wear-resistant materials.
High quality surface finishes for easy cleaning.
Other materials and finishes are available upon request
Machine is self-draining.
Low noise levels.
DISADVANTAGES
Requires high power for the running of the colloidal mill.
Using of wet materials.
Consumes more energy.

Colloidal silver is particles of silver broken down or mixed into liquid. In the early 20th, ,century colloidal silver or as it is more popularly known “silver water” was marketed as a cure for tumors; now in alternative medicine it is referenced as a cure all with healing properties.
The backbone of the system is the patented bullet system. This is a system entirely designed by the company. It consists of large motors that create vacuum through 8” pvc, which can move linen at a high rate of speed. Counting bins can also be incorporated into this system.It can perform a number of tasks.
Often after mixing an emulsion foam is produced. Foam is produced when pockets of air are trapped in a solid or liquid. Foams are a type of colloid. A colloid is a mixture between homogeneous and heterogeneous mixtures. Beaten egg whites and whipped cream are examples of trapped air in liquids. Marshmallows are an example of air trapped in solids.
The concentrate is dried and sent into a reverberatory furnace. The minerals are partly oxidized and melted, resulting in isolated layers. The matte layer refers to the iron-copper sulfide mixture which sinks to the bottom. The slag, which refers to the remaining impurities, floats on top of the matte and the discarded. Sulfur dioxide gases are also collected and made into sulfuric acid for use in hydrometallurgical leaching. The matte is recovered and moved to the converter, a cylindrical vessel into which the copper is poured. Air, lime and silica are added to react with the metal oxide. The slag is removed and the Sulfur dioxide and converted into sulfuric acid, this forms blister copper which is 97-99% pure.
• Milling – The first step of the process is crushing the malt. This breaks apart the grains, exposing the starchy ball inside and making it accessible to the brewer. The grains are only lightly crushed, leaving the hulls intact to serve as a filter bed for the lautering process later on.
The experiment was built in order to test our abilities to efficiently and correctly execute a separation of mixtures through deep brainstorming and teamwork.
A magnetic stir bar is kept underneath the 250-ml beaker so that the mixture gets dissolved
It makes the results as accurate as possible, as it allows the hydrochloric acid to be added drop by drop when the sodium hydroxide is close to neutralising. · Burette Stand - This holds the burette steady in place. · Funnel - This allows hydrochloric acid to be poured into the burette so none is spilt. · Pipette - This is used to accurately draw out the correct amount of a substance from a solution. · Safety Filler - This is used to draw the substance up the pipette

The basic trimmer works by the engine driving a multi-bearing supported hardened steel shaft housed in an aluminium tube through a centrifugal clutch this shaft is connected to a “head” that holds a nylon line that spun at high revolutions per minute (RPM). This nylon line then cuts the grass by hitting the blades of grass at high speed, this cause the grass to be severed at the point of impact. Thus trimming the grass.
Two holes in the top of the tank, to charge the reactant and to transfer out the reactant.
On repeating this experiment more care should be taken when purifying to remove the solvent impurities and minimise loss of crude product.
Particle size influences many properties of particulate materials and is a valuable indicator of quality and performance. This is true for powders, suspensions, emulsions, and aerosols. The size and shape of powders influences flow and compaction properties..

Granulation is a common technique used to produce powders that can be compacted. In this process, the particles are enlarged via agglomeration of the particles while still maintaining the original particles integrity.
