Conical Mill
A conical mill (or conical screen mill) is a machine used to reduce the size of material in a uniform manner. It is an alternative to the hammermill or other forms of grinding mills. As the name implies, the conical mill varies in diameter from where the feed enters to where the product exits. The conical mill operates by having the product being fed into the mill by gravity or vacuum. A rotating impeller forces the material outward to a conical screen surface, where it is sized and passed through the openings in the screen. Once finished, the product simply drops through the milling chamber to a receptacle underneath. Conical mills come in a variety of sizes from tabletop lab models to full-size high-capacity machines for use in processing large quantities of material, and the impeller and screen can be customized for each individual use. The machines can be used not only to reduce the size of particles, but also for deagglomeration, sieving, dispersion, and mixing. The applicat ...

Hammermill
A hammer mill is a mill whose purpose is to shred or crush aggregate material into smaller pieces by the repeated blows of little hammers. These machines have numerous industrial applications, including: * Ethanol plants (grains) * A farm machine, which mills grain into coarse flour to be fed to livestock * Fluff pulp defiberizing * Fruit juice production * Grinding used shipping pallets for mulch * Milling grain * Sawmills, size reduction of trim scrap and planer shavings into boiler fuel or mulch * Shredding paper * Shredding scrap automobiles (see automotive shredder residue) * Shredding yard and garden waste for composting * Crushing large rocks * In waste management Operation The basic principle is straightforward. A hammer mill is essentially a steel drum containing a vertical or horizontal rotating shaft or drum on which hammers are mounted. The hammers are free to swing on the ends of the cross, or fixed to the central rotor. The rotor is spun at a high speed inside t ...

Mill (grinding)
A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind (windmill) or water (watermill). In modern era, they are usually powered by electricity. The grinding of solid materials occurs through mechanical forces that break up the structure by overcoming the interior bonding forces. After the grinding the state of the solid is changed: the grain size, the grain size disposition and the grain shape. Milling also refers to the process of breaking down, separating, sizing, or classifying aggregate material (e.g. mining ore). For instance rock crushing or grinding to produce uniform aggregate size for construction purp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Detergent
A detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. There are a large variety of detergents, a common family being the alkylbenzene sulfonates, which are soap-like compounds that are more soluble in hard water, because the polar sulfonate (of detergents) is less likely than the polar carboxylate (of soap) to bind to calcium and other ions found in hard water. Definitions The word ''detergent'' is derived from the Latin adjective ''detergens'', from the verb ''detergere'', meaning to wipe or polish off. Detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. However, conventionally, detergent is used to mean synthetic cleaning compounds as opposed to ''soap'' (a salt of the natural fatty acid), even though soap is also a detergent in the true sense. In domestic contexts, the term ''detergent'' refers to household cleaning products such as ''laundry detergent'' or '' dish ...

Pearl
A pearl is a hard, glistening object produced within the soft tissue (specifically the mantle) of a living shelled mollusk or another animal, such as fossil conulariids. Just like the shell of a mollusk, a pearl is composed of calcium carbonate (mainly aragonite or a mixture of aragonite and calcite) in minute crystalline form, which has deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes, known as baroque pearls, can occur. The finest quality of natural pearls have been highly valued as gemstones and objects of beauty for many centuries. Because of this, ''pearl'' has become a metaphor for something rare, fine, admirable and valuable. The most valuable pearls occur spontaneously in the wild, but are extremely rare. These wild pearls are referred to as ''natural'' pearls. ''Cultured'' or ''farmed'' pearls from pearl oysters and freshwater mussels make up the majority of those currently sold. Imitation pearls are also widely s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rouge (cosmetics)
Rouge (; meaning "red" in French), also called blush or blusher, is a cosmetic for coloring the cheeks in a variety of shades, or the lips red. It is applied as a powder, cream or liquid. History The Ancient Egyptians were known for their creation of cosmetics, particularly their use of rouge. Ancient Egyptian pictographs show men and women wearing lip and cheek rouge. They blended fat with red ochre to create a stain that was red in color. Greek men and women eventually mimicked the look, using crushed mulberries, red beet juice, crushed strawberries, or red amaranth to create a paste. Those who wore makeup were viewed as wealthy and it symbolized status because cosmetics were costly. In China, Rouge was used as early as the Shang Dynasty. It was made from the extracted juice of leaves from red and blue flowers. Some people added bovine pulp and pig pancreas to make the product denser. Women would wear the heavy rouge on their cheeks and lips. In Chinese culture, red symb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Face Powder
Face powder is a cosmetic product applied to the face to serve different functions, typically to beautify the face. Originating from ancient Egypt, face powder has had different social uses across cultures and in modern times, it is typically used to set makeup, brighten the skin and contour the face. Face powders generally come in two main types. One of which is loose powder, which is used to assist with oily skin in absorbing excess moisture and mattifying the face to reduce shininess. The other is pressed powder which conceals blemishes and maximises coverage. The use of face powder has contributed to beauty standards throughout history. In ancient Europe and Asia, a whitened face with a smooth complexion signalled a woman of high status. The prevalence of this trend was carried throughout the Crusades and Medieval era. During this time, women used harmful ingredients as face powder including bleaches, lead and lye. Early history Egypt Archaeological remains and chem ...

Raisin
A raisin is a dried grape. Raisins are produced in many regions of the world and may be eaten raw or used in cooking, baking, and brewing. In the United Kingdom, Ireland, New Zealand, and Australia, the word ''raisin'' is reserved for the dark-colored dried large grape, with '' sultana'' being a golden-colored dried grape, and '' currant'' being a dried small Black Corinth seedless grape. Etymology The word "raisin" dates back to Middle English and is a loanword from Old French; in modern French, ''raisin'' means "grape", while a dried grape is a ''raisin sec'', or "dry grape". The Old French word, in turn, developed from the Latin word '' racemus'', "a bunch of grapes". Varieties Raisin varieties depend on the type of grape and appear in a variety of sizes and colors including green, black, brown, purple, blue, and yellow. Seedless varieties include the sultana (the common American type is known as Thompson Seedless in the United States), the Zante currants (black Corin ...

Cranberry
Cranberries are a group of evergreen dwarf shrubs or trailing vines in the subgenus ''Oxycoccus'' of the genus ''Vaccinium''. In Britain, cranberry may refer to the native species ''Vaccinium oxycoccos'', while in North America, cranberry may refer to ''Vaccinium macrocarpon''. ''Vaccinium oxycoccos'' is cultivated in central and northern Europe, while ''Vaccinium macrocarpon'' is cultivated throughout the northern United States, Canada and Chile. In some methods of classification, ''Oxycoccus'' is regarded as a genus in its own right. They can be found in acidic bogs throughout the cooler regions of the Northern Hemisphere. Cranberries are low, creeping shrubs or vines up to long and in height; they have slender, wiry stems that are not thickly woody and have small evergreen leaves. The flowers are dark pink, with very distinct ''reflexed'' petals, leaving the style and stamens fully exposed and pointing forward. They are pollinated by bees. The fruit is a berry that i ...

Breadcrumbs
Bread crumbs or breadcrumbs (regional variants including breading and crispies) consist of crumbled bread of various dryness, sometimes with seasonings added, used for breading or crumbing foods, topping casseroles, stuffing poultry, thickening stews, adding inexpensive bulk to soups, meatloaves and similar foods, and making a crisp and crunchy covering for fried foods, especially breaded cutlets like tonkatsu and schnitzel. The Japanese variety of bread crumbs is called ''panko''. Types Dry Dry breadcrumbs are made from dry breads which have been baked or toasted to remove most remaining moisture, and may have a sandy or even powdery texture. Bread crumbs are most easily produced by pulverizing slices of bread in a food processor, using a steel blade to make coarse crumbs, or a grating blade to make fine crumbs. A grater or similar tool will also do. Fresh The breads used to make soft or fresh bread crumbs are not quite as dry, so the crumbs are larger and produce a softer ...
