Efficient Grinding of Sulfur by ELE Sand Mill and Basket Mill D90 Analysis

As a core raw material in pesticide suspension concentrates (SC) and rubber vulcanization systems, sulfur grinding has long been plagued by industry pain points including flammability, explosiveness and easy electrostatic agglomeration. To guarantee absolute production safety while improving the suspension rate of sulfur, more and more agrochemical enterprises are phasing out conventional equipment and switching to automated wet grinding devices developed by professional grinding equipment manufacturers. In this field, the ELE basket mill developed by ELE has become a benchmark product for sulfur processing with its unique design concept.

Aiming at the characteristics of sulfur such as large single-batch processing capacity and easy caking, ELE’s R&D team combines basket milling technology with an intelligent circulation system. In practical tests, the volume average diameter of the original sulfur sample is 73.03 μm and D90 reaches 203.4 μm. Direct application in suspension concentrate production will easily lead to caking and precipitation. After wet grinding with ELE equipment, test data shows that the volume average diameter of materials is rapidly reduced to 2.053 μm, and D90 is successfully controlled at 6.641 μm. This excellent D90 data greatly improves the suspension stability of sulfur micropowder in aqueous systems.

Safety and temperature control are the core priorities of the sulfur grinding process. As a leading sand mill manufacturer, ELE adopts fully enclosed explosion-proof structure and high-efficiency cooling jacket for the basket mill chamber. Heat generated during grinding can be removed in a timely manner, completely eliminating hidden dangers of sulfur melting or safety accidents. Meanwhile, the powerful suction turbine equipped on ELE sand mill series can quickly draw sulfur floating on the liquid surface into the grinding basket, greatly improving the single-machine production efficiency.

For modern production workshops, equipment flexibility and energy consumption ratio directly affect factory profitability. ELE basket mills support multi-barrel continuous operation for one unit; they are extremely easy to clean and significantly cut downtime between batches. Many agrochemical enterprises have achieved double production capacity and lower energy consumption after introducing ELE sand mills and basket milling equipment.

The popularization of sulfur ultra-fine wet processing technology is pushing the agrochemical industry toward greener and more efficient development. As a reliable grinding equipment manufacturer, ELE is always committed to serving customers with high-quality equipment. In the future, ELE will further explore the sulfur and pesticide formulation grinding market and escort the high-quality industrial development with more competitive ELE sand mill products.
