Recent technological breakthroughs in bentonite grinding have injected new momentum into the efficient utilization of
this versatile non-metallic mineral, often hailed as the "clay of a thousand uses." As industries increasingly demand higher
quality and finer bentonite powder, the development and application of advanced grinding technologies have
become a key industry focus.
Bentonite, with montmorillonite as its main mineral component, possesses excellent properties such as adsorbability,
ion exchangeability, and cementation. It is widely used in various fields including foundry, drilling mud, environmental
protection, agriculture, and building materials. In the foundry industry, bentonite acts as a binder and plays a key role in
the performance of molding sand. In the field of environmental protection, its strong adsorption capacity makes it an ideal
material for sewage treatment and soil remediation. In agriculture, bentonite can be used as a soil conditioner and pesticide
additive, helping to improve crop yield and quality. However, different application scenarios have significantly different
requirements for the fineness of bentonite powder. Ranging from less than 200 meshes for feed additives to more than 325
meshes for chemical additives and the papermaking industry, precise grinding has become a core link to meet market demands.
To address this challenge, many equipment manufacturing enterprises have actively engaged in technological innovation. For instance,
the HVM series large-scale ultra-fine vertical mills and high-efficiency pulverizers launched by Hefei Hengcheng, through the iteration
of classification technology and process upgrading, have not only significantly improved the production efficiency of bentonite but also
ensured the stability of powder quality. These devices can grind bentonite to specific fineness according to different needs, and the produced
powder features high whiteness, high purity, and good dispersibility, which has greatly expanded the application potential of bentonite in the
high-end market.
Meanwhile, intelligent technologies have gradually been integrated into bentonite grinding production lines. Through the PLC automatic control
system, the entire process from raw material feeding to product powder output has been automated and fully enclosed. This not only improves
production efficiency but also reduces labor costs and dust pollution, conforming to the current industrial development trend of green environmental
protection. Take a large-scale bentonite processing enterprise as an example. After adopting intelligent grinding equipment, its product qualification
rate has increased from 92% to 99.5%, and its production capacity has also been significantly improved.
With the continuous advancement of technology, bentonite grinding is developing towards higher efficiency, intelligence, and greener practices. This will
not only promote the transformation and upgrading of the bentonite industry itself but also provide higher-quality and more diversified products for mandownstream industries. It will further tap the "versatile" value of bentonite and help related industries achieve high-quality development.
