3． Working Principle: Perlite Powder Valve Bag Packing Machine

Materials are fed into buffer bin from finished product hopper through pneumatic valve on the top of buffer hopper or star discharger. Then materials are filled into packing bag through the high-speed rotating impeller controlled by frequency conversion. Valve controls feeding quantity, when filling weight reaches preset value, impeller will stop running, feeding valve closes, bag holder opens through control system and packing bag will be manually taken off, thus single packing is finished. The weighing instrument of FW type packing machine can choose both gross and net weighing packing.

Definition of Perlite :

Perlite is a kind of volcanic eruption acid lava, vitreous rock formed by rapid cooling, [1] is named for its pearl fissure structure. Perlite mines include perlite, obsidian and turpentine. The difference between the three is that perlite has arc-shaped cracks formed by condensation, called perlite structure, with a water content of 2~6%; turpentine has a unique luster with a water content of 6-10%; obsidian has glass Luster and shell-shaped fracture, the water content is generally less than 2%.

Process characteristicsedit：

When the acidic lava erupts on the surface, it has a great viscosity due to the sudden cooling of the magma, so that a large amount of water vapor cannot escape from the magma and is stored in the glass. When firing, due to sudden heating to a softening degree, the combined water vaporizes in the glass to produce a lot of pressure, and the volume expands rapidly. When the vitreous is cooled below its softening temperature, it condenses into a cavity structure to form porous expanded perlite. Therefore, glass is the basic condition that causes ore expansion, water is the internal cause of ore expansion, and iron is one of the unfavorable factors affecting ore expansion.

The oxidation and melting temperature of perlite is: the initial shrinkage temperature is 1025°C, the softening temperature is 1175°C, the melting temperature is greater than 1500°C, the softening temperature range is 150°C, and the melting temperature range is 325°C. The temperature at which perlite begins to shrink is 120°C lower than that of feldspar, and its softening temperature is 75°C lower, and the softening range is widened by 95°C. Because of these characteristics, perlite can greatly reduce the firing temperature in the firing of ceramic products and improve the quality of sintering. Through further research, perlite has another characteristic, that is, in the ceramic body containing perlite, mullite crystals are formed earlier, which is beneficial to the development of the sintering process. In this way, the perlite-bearing body not only has the same technological characteristics as the feldspar-quartz-clay (kaolin mineral) ternary body formula, but also reduces the firing temperature (from the original 1280 ℃ to 1180℃-1160℃), and has good thermal stability.

Appearance edit：

Morphology is one of the most striking appearance characteristics of perlite. Different characteristic forms of perlite, the same type of perlite, because of the different formation conditions, internal structure, composition, etc., often have other characteristics that may appear in different forms. It is a sign of identifying perlite and analysis of the origin of perlite. in accordance with.

The study on the morphology of crystalline perlite is based on monomer and aggregate. Therefore, the shape of perlite is not only. For solid amorphous quasi (or similar) perlite, there is only a single crystal of perlite, which is the monomer form of aggregate perlite. The morphology of perlite monomer mainly includes two aspects: perlite crystal crystallization habits (specifically reflected in the crystal shape) and crystal face patterns.

Crystal habit

Under certain growth conditions, the same kind of crystals can always develop into a certain shape. This property is called the crystal habit or crystal habit for short. According to the development characteristics of perlite crystals in three-dimensional space, the crystalline habits are usually divided into three types, namely, one-way elongated type: the crystals are particularly developed in one direction and are columnar, needle-shaped, fibrous, etc., such as columnar quartz , Needle-like ordinary hornblende, fibrous gypsum, asbestos, etc.; two-way extended type: crystals are particularly developed in two directions, in the form of scales, flakes, and plates, such as flake mica, plate gypsum, etc., Three-dimensional isometric type: The crystals have almost the same degree of development in three-dimensional space and are equiaxed or granular, such as cubic stone salt, pyrite, etc.

In addition to the three basic types mentioned above, there are some transitional types in the crystallization habits of perlite. For example, the plate-column shape between the one-way extension and the two-way long type, the thick plate between the two-way extension and the three-way equal length, the short column between the three-way equal length and the one-way extension, etc. .

The shape of perlite monomer is firstly related to its structure, composition and other internal factors. For example, perlite with chain-like complex anion groups in a structure such as hornblende, often develops into columnar, needle-like, and fibrous shapes along the chain. In addition, the shape of perlite monomer is also controlled by the external environment during crystal growth. For example, due to different temperatures during growth, the cut surface of the shaft is diamond-shaped. Another example is calcite crystals can take more than 800 shapes due to different growth temperatures.
