The bead mill/ sand mills are widely used in pint, ink, chemicals, Agro chemical and coating industries for size reduction and dispersing of pigments in liquid, Particle size reduction up to 2 microns re possible in a single pass. The ancestor of the Modern Pressurized Horizontal Sand Mill is Bead Mill. The working principle of bead mill is feed to be processed is pressurized pumped from the bottom of the mill into the milling chamber which is filled with grinding media .The grinding media is agitated by number of impellers which are fitted on a lengthy drive shaft. The complete impeller assembly is rotate on high speed and creates pressurized movement of grinding material and on feed. As the material moves upwards it is subjected to high hydraulic & shearing forces between the grinding media which results in fine grinding of the material. This material then passes through the micron gap disc which separates the media from the process material. All mills are provided with a mechanical seal with hydraulic pressure and jacket arrangement for cooling the material in the grinding chamber. SALIENT FEATURES: v Designed as per cGMP – Current Good Manufacturing Practices & Non GMP STANDARD Model. v Contact parts in AISI 316 OR AISI 304 as desired by customer. v A very large no. of small balls could be crowded together to do a superior grinding / milling of product as compared to just a few large balls with smaller no. of contact points. v The work is done primarily by shear on the solids of the slurry following through the spacers in the beads as the solid particle in the slurry and the beads move past each other at different velocities. v Available in 50 kg to 1000 kg capacity. v Vertical and integrated design of grinding mechanism, feed pump and electric controlled box make the mill ideal for easy operations and space saving. v The circulating cooling system effectively maintains the optimal operating temperature v Feed pump is equipped with inverter controlled transmission motor to achieve the best materials feeding v With advancement of metallurgy & mechanical seal technologies the horizontal mills were developed which turned out to be more efficient because of mechanical advantages.
