Tri-Chilled Roller Mill
- Tri-Chilled type Three Roller Mill incorporate all of the newest design features and advanced technologies on production size Three-Roller Mill. Wide range of applications for low to high viscosity masses. material to be milled is placed between the feed and center rolls. Each adjacent roll rotates in different speeds that generate shear forces to disperse the material.
- Rollers are made of harden high density FCMW34 chilled iron with a uniform hardness on the roller surface. The surface hardness is over HS70°.
Except Model : HMA-305 laboratory type, 3"dia Laboratory type are made of SACM Nitrogen Steel, the surface hardness is HV900°. The deep chilled rollers can withstand rapid high pressure and temperature changes that makes the rollers can be used continuously in a longer time.
All rollers are ground parallel and tested for maximum accuracy of hardness and durability.
Finished ground products are finely homogenized that fineness can be down to 5μm.
- All three rollers equip heavy duty Double Row Self-Aligning Spherical Roller Bearing which automatic produce balanced alignment of the rollers, and precise optimal self-regulation gap between rollers. Each roller equips a independent full length water cooling bored chamber to maintain constant temperature and uniform dispersion across the entire surface of the roller for best production quality.
Glossary of ink terms
The penetration of ink into the surface of the paper stock by capillary attraction between the ink vehicle and paper fibres or coating.
Part of the ink vehicle that binds the pigment to the paper, usually a heavy bodied drying oil or resin.
The spreading or running of a pigment by the action of a solvent, e.g. water, oil, etc.
Bodied Linseed Oil
Linseed oil, thickened by heating until the desired viscosity has been obtained.
Printing with a stick size and dusting same with finely powdered metal particles to give the appearance of metal finishing.
Flowing of an ink beyond the limits of the design or image area.
Substances which accelerate the rate of oxygen absorption or drying of oils, varnishes or vehicles. These usually comprise organic salts of lead, manganese or cobalt.
The ability of ink to spread over a surface or into a thin film.
The property of an ink or varnish whereby it may be drawn into strings before breaking. The longer the strings the longer is the ink or varnish.
Oil pressed, or extracted from flax seeds. It is the most widely used vegetable drying oil and is main ingredient of printing ink and paint vehicles.
Linseed oil, or other drying oil that has been bodied by heating to produce a vehicle of proper viscosity for use in litho ink.
The solidifying of printing inks over time caused by chemical reactions between the ingredients.
An ink termed opaque will cover the body cover of the stock being printed, or any matter which it is overprinting. The degree varies considerably with the colour and type of ink, even those described as opaque.
The lifting or pulling of fibres or coating off the stock due to tack of ink.
Liquid materials added to ink to reduce its consistency or tack.
Inks which allow light or colour to pass through them, often changing the base colour/s.
An ink which possesses a buttery consistency and breaks off with short strings when an attempt is made to draw it out between fingers. Prone to spin off rollers at high speed.
The adhesiveness of an ink for another surface. It is the stickiness or pull observed when tapping the ink out onto a piece of paper.
The ability of a printed film to accept overprinting with another colour.
The liquid portion of an ink that holds and carries the pigment and provides workability or press drying properties and binds the pigment to the paper after the ink has dried.
The resistance to flow of an oil, varnish or ink caused by internal friction between the particles comprising it. In simple terms it may be considered as a thickness or thinness of oil, varnish or ink from the standpoint of flow properties.
