The Puhler series horizontal eccentric disc mill is currently one of the most widely used sand mills in the industry. The maximum capacity of Puhler's series of sand mills can reach 2,500 liters. Compared with traditional sand mills, it has the following advantages:

• The stirring disc can be of eccentric, triple eccentric, or circular structure, arranged in a specific order, overcoming the drawback of uneven distribution of grinding media in traditional machines, resulting in high grinding efficiency. It is suitable for grinding materials that are difficult to disperse or products requiring high fineness.
• Due to the effect of centrifugal force, the hollow-structured rotor rotates together with the main shaft.
• There are almost no grinding balls inside the hollow rotor, the discharge separator system is wear-free, the discharge flow area is large, the filtration effect is good, and the service life is long.
• Two-way sliding mechanical seal device with coolant, offering good sealing performance and reliable operation, ensuring the reliability of bearing operation.
• High processing capacity, suitable for industrial online continuous production.
• Narrow particle size distribution range, high uniformity
• No dead corners, 100% dispersion and shearing of materials
• Eliminate quality variations between production batches
• Low noise, smooth operation
• Simple operation, easy to handle and maintain
• Time-saving, efficient, and energy-saving
• Sturdy structure, compact design
• No special foundation required
Working Principle:
Horizontal closed sand mill is a high-efficiency chemical equipment that adopts wet grinding and dispersion, with a horizontally installed cylinder and continuous closed production. The pre-dispersed and wetted solid-liquid mixed material is fed into the cylinder by a pneumatic double diaphragm pump (or gear pump, hose pump). The material, along with the grinding media inside the cylinder, is agitated by a high-speed rotating disperser assembly, causing intense collision and shear between the solid particles in the material and the grinding media. This achieves the purpose of grinding and dispersing particle aggregates within a short period. The grinding and dispersion effect and efficiency are **excellent**, making it an essential piece of equipment for producing high-quality paints, inks, dyes, and other products.
