Lab conical ball mill description
Lab conical ball mill is a type of milling equipment specifically designed for laboratory-scale applications. This apparatus features a conical design, characterized by its tapered cylindrical shape which narrows from the feeding end to the discharging end. It typically consists of a rotating drum mounted horizontally, with a conical end, and is equipped with grinding media such as steel balls or steel bars. The conical design helps to enhance the efficiency of the milling process by promoting a more uniform particle size distribution and improving the grinding action.
Lab conical ball mills are widely used in various scientific and industrial research fields. Their primary applications include:
1.For preparing finely ground samples for X-ray diffraction (XRD) and other analytical techniques.
2. For grinding active pharmaceutical ingredients (APIs) and other materials to fine powders.
3.For the synthesis of novel compounds through mechanochemical processes.
4.For the comminution of ores and other materials for subsequent analysis.

Working Principle
The working principle of a conical ball mill is based on impact and attrition. Here’s a step-by-step outline of its operation:
1. Material to be ground is fed into the mill’s drum through a hopper. The quantity of material and grinding media (balls) are adjusted based on the specific requirements of the milling process.
2. The drum is rotated around its horizontal axis by an electric motor. As the drum rotates, the grinding media inside is lifted along the inner walls of the drum due to the motion.
3. When the grinding media reaches a certain height, it falls back onto the material, causing impact and attrition forces that reduce the particle size.
