  • 15L Nano Rod Pin Sander

    Dongguan Le Chi Machinery Technology Co., Ltd. introduced advanced grinding technology from Germany, specializing in wet grinding equipment research and development, production of high-tech joint-stock limited company, focusing on the field of material grinding, fineness solutions. It has extensive and advanced production technology, representing international grinding technology. The trademark registered in China is Le Chi, which is protected by China Technical Bureau. It adopts German DIN industry and European EMC product standard design, and has also obtained ISO 9001 standard certification. Through the application of advanced hydromechanics and mechanochemistry, Leech designed the core technology of grinding components, and combined the grinding technology verified by scientific experiments with high-quality grinding equipment. It is aimed at improving the field of material wet grinding, high-energy ultra-fine dispersion and grinding technology. The existing wet bar pin horizontal grinder, wet disc horizontal grinder and wet blue are available. It is widely used in industrial coatings, ink, paint, food (chocolate, cocoa powder), medicine, cosmetics, fine chemicals, ceramics, mineral processing, papermaking, cellulose, batteries, new materials and other fields. Grinding principle Horizontal grinder is a kind of ultra-fine particle disperser with horizontal continuous production. Its operation method is to use high-viscosity pumps such as diaphragm pump and gear pump to input pre-dispersed wetted solid-liquid mixture into the grinding tank of the main engine. The grinding tank is filled with appropriate grinding medium, and the grinding medium is given enough kinetic energy by rotating the dispersed blade at high speed. The impact of solid particles in bulk materials produces shear force, which produces more intense collision, friction and shear effects, so as to accelerate the friction of fine particles and disperse the aggregation. It is then separated by a special separator. Separate the dispersed material from the medium and discharge it from the outlet. It is suitable for fine grinding with medium and high viscosity particle size. Such as paint, fuel, pigments, cosmetics, pesticides, electronics, paper and other raw materials dispersion.

  • 90L-200L High Efficiency Horizontal Sander

    Le Chi's Uniqueness Converting the traditional vertical barrel type horizontal grinder to conical barrel type grinder, the reflective track of beads inside the grinding barrel is changed, the reciprocating motion ability of grinding beads and the friction and impact ability between beads are strengthened, thus the efficiency of the vertical barrel type grinder is increased by nearly 30%. Horizontal grinder, which used to be cooled by sand barrel, was strengthened to four-position cooling of grinding barrel (stator), dispersing disc (rotor), front plate and separator, which strengthened the dispersive potential area of grinding machine and effectively improved the cooling and heat dissipation capacity of the machine. The material temperature during grinding could be effectively controlled below 50 C. If used together with water cooler, the grinding heat sensitivity would be improved. When the sensory material is used, the cooling effect is more remarkable. With the programmed control function of PLC, the working time and requirements of the machine can be monitored in real time in advance, and the site can be instantly understood and controlled in the office by connecting the Ethernet and office computer. The improved rocker arm design enables a person to easily dismantle the machine. When cleaning and repairing the inside of the machine, it is safer and more convenient. Self-developed double mechanical seals can be cooled by solvents that are compatible with materials (traditional mechanical seals usually need oil to cool), avoiding oil leaking into materials due to natural wear after long-term use of mechanical seals, and causing unnecessary economic losses to users. Grinding operation Start the pump and input material to the grinding machine until the material is out of the grinding machine outlet (the pump motor and the main engine are interlocking control, the main engine must be started within 20 seconds, otherwise the pump will stop by itself, and the pump can be started several times, using the grinding chamber to fill the material to prevent the machine from dry grinding).
