Description
Low Temperature Planetary Ball Mill
Product Introduction
Low temperature planetary ball mill is a combined equipment of planetary ball mill and refrigeration device. During high-speed grinding, most materials will heat up due to friction or exothermic reactions, which may alter the physical and chemical properties of materials and produce negative grinding effects. Low temperature planetary ball mill is mainly used for material grinding processes requiring strict temperature control.
Operating Principle of Planetary Ball Mill
Four grinding jars are installed on the main disc of the planetary ball mill. When the motor drives the main disc to rotate, the grinding jars revolve around the main disc axis and rotate simultaneously driven by the planetary mechanism, performing planetary motion. The grinding balls inside the jars rub and collide with each other under high-speed planetary motion, enabling efficient sample grinding and mixing.
Product Application
Low temperature planetary ball mill is widely used in geology, mineral resources, metallurgy, electronics, building materials, ceramics, chemical industry, light industry, medicine, environmental protection and other fields.It is suitable for the production of electronic ceramics, structural ceramics, magnetic materials, lithium cobalt oxide, lithium manganate, catalysts, fluorescent powders, long afterglow luminescent powders, rare earth polishing powders, electronic glass powders, fuel cells, zinc oxide varistors, piezoelectric ceramics, nanomaterials, wafer ceramic capacitors, MLCC, thermistors (PTC, NTC), zinc oxide varistors, dielectric ceramics, alumina ceramics, zirconia ceramics, fluorescent powders, zinc oxide powder, cobalt oxide powder, Ni-Zn ferrites, Mn-Zn ferrites and other products.
Product Features
Low temperature planetary ball mill is a combined equipment of planetary ball mill and air cooling device. The air cooling unit adopts the air-conditioning compression refrigeration principle, and the cold air circulation quickly removes heat generated during grinding. According to ambient temperature differences, the temperature of the grinding chamber can be controlled at 5–15℃. It is mainly used for ultra-fine grinding of materials under low-temperature processes. The air cooling device features simple structure, convenient operation, easy maintenance and low energy consumption.
