First, the knot machine - dryer working principle
The drum knotting machine is a cooling and crystallizing process, in which the molten material is contacted with the cooling drum and the material film is formed on the surface of the drum, and the film is cooled, crystallized and crystallized by heat exchange between the film and the wall of the stock Of the film is scraped by a scraper, a sheet-like products.
Drum drying is through the rotating drum, heat transfer way, will be attached to the outer wall of the material or belt-like material for drying a dry operation of the process.

In order to provide users with standard specifications or to provide special specifications according to the drum knot (dry) machine
1, the working principle
The drum knot is a cooling and crystallizing process. The molten material in the tray is contacted with the cooling drum. The material film is formed on the surface of the drum. The film is cooled, crystallized and crystallized by heat exchange between the film and the drum. Of the material scraped by scraper, a flake product. Drum drying is through the rotating drum to heat conduction way, will be attached to the outer wall of the liquid phase material or strip-like material for heating and drying of a continuous operation of equipment. In this case,
In this case,
2, the scope of application:
The device is suitable for melting point of 400 ℃ in the various types of low-melting point materials.
3, typical materials:
Polyethylene oxide oligomer, petroleum resin, polyethylene oxide and other polymer products; phthalic anhydride, maleic anhydride, naphthalene, flat, high fatty alcohols, chloroacetic acid, trihydroxy propane, guanidine nitrate, bisphenol A, Acid and other organic chemical products; sulfur, sodium sulfide, caustic soda, sodium hydrosulfide, calcium chloride and other inorganic chemical products. In this case,
In this case,
4, the technical advantages:
◇ performance of the leading domestic, to the late 1990s, the level of foreign equipment;
◇ equipment compact structure, small footprint;
◇ drum high precision, good product uniformity;
◇ The use of multiple sets of scraper, flexible adjustment;
◇ semi-pipe jacket type tray, safe and reliable;
◇ with side scraper, drum side to avoid the drum material.
Hot melt molding method Hot melt molding method:
Hot melt molding method Hot melt molding method is the use of the product's low melting point characteristics (usually less than 300 ℃), the molten material through a special condensation method, so that the crystallization of the required crystallization of the chip, strip, Like shape. According to the working principle of molding equipment, can be divided into drum knot machine and cold-roll die-molding device.
The drum knot is a cooling and crystallizing process. The molten material in the tray is in contact with the cooling drum and forms a film on the surface of the drum. The film is cooled, crystallized and crystallized by the heat exchange between the film and the drum wall. Of the film is scraped by a scraper, a sheet-like products. The drum knotting machine has the advantages of compact equipment, high precision drum, good cooling effect, wide range of application, can be knotted and dried, etc. It can be widely used in petroleum resin, polyethylene oligomer and other polymer products and Phthalic anhydride, maleic anhydride, higher fatty alcohols and other organic chemical products. Drum knot machine in the powder industry in China has been more common, more mature technology.
The material is suitable for a wide range of applications, and it can produce hemisphere, strip, block, block, block, block, Sheet-like and other shapes of products. The use of cloth and steel dual-speed drive device, according to the production capacity and physical parameters of regulation, easy to achieve automatic control; the entire production process pollution-free, high purity, no impurities into, easy to achieve continuous operation; The commutation bending at the discharge end separates the bonding surface between the solidified material layer and the steel strip, so that the powder is less pulverized at the time of discharge, the discharge is easy, and the particle shape is easy to maintain
