Clay minerals including kaolin, bentonite, fire clay and pottery clay serve as core raw materials for ceramic feedstock, coating fillers, rubber plastic additives, construction materials, drilling muds and cosmetic ingredients.
Clay materials feature an internal layered structure and surface adhered moisture. Conventional ball mills and Raymond mills suffer from prominent drawbacks such as high energy consumption, inconsistent powder particle size, easy breakage of lamellar clay crystals, severe dust pollution and complicated drying grinding procedures.
Selecting main frame equipment matched to the properties of clay based materials holds the key to quality and efficiency improvement and added-value control of finished powder for the whole clay grinding production line. SBM LM Vertical Grinding Mill and LUM Ultrafine Vertical Grinding Mill are adaptable to varied requirements on fineness and output of clay powder.
Difficulties in Raw Clay Processing and In built Adaptability of LM Vertical Roller Mill for Calcined Clay Working Conditions
Clay materials generally come with prominent characteristics including strong stickiness, tendency to adhere to machinery, high raw material moisture content, fragile lamellar crystals and strict classification standards for finished products.
Ordinary crushing machines operate on impact based comminution, which easily damages the layered structure of clay minerals and impairs the adsorption capacity of bentonite as well as the whiteness and covering power of kaolin. In contrast, LM Vertical Mill adopts the bed grinding principle. Its grinding rollers apply gentle compression and shearing force to strip mineral lamellas along clay’s natural cleavage planes.
The built in hot air drying system enables one-step processing of damp wet clay. It integrates crushing, drying, grinding, classification and conveying into a single unit, making it perfectly suited for the full-set clay production workflow.

Core Advantages for Calcined Clay
1. Integrated Process to Simplify Overall Production line Layout
The LM vertical mill incorporates crushing, hot air drying, roller compaction grinding, turbine powder selection and enclosed conveying within one single machine.
2. Flexible Material Bed Grinding to Preserve the Activity of Clay Lamellar Crystals
Hydraulically pressurized grinding rollers squeeze clay on the material bed at a constant speed. Free from high intensity impact crushing, the equipment keeps the layered structure of bentonite and kaolin intact.
3. Energy saving Performance and Stable Longtime Continuous Operation
The thin oil circulating lubrication system guarantees steady operation under heavy load working conditions. Multiple protection sensors for vibration and temperature cut down breakdown risks caused by clay adhesion and material blockage, supporting round the clock non-stop production.
4. Fully negative pressure Enclosed Operation for Easy Compliance With Environmental protection Requirements
The whole set machine runs under negative pressure together with a pulse dust collector. Fine clay powder is prevented from escaping into the air, eliminating heavy dust pollution during clay processing.
Applicable Production line Scenarios
It produces 20-400 mesh ordinary clay powder, pottery clay raw materials, fire clay, bentonite powder for engineering slurry and raw materials for red bricks and ceramics.
High value added Ultrafine Clay Powder｜LUM Ultrafine Vertical Grinding Mill

Under such circumstances, the LUM ultrafine vertical mill serves as your dedicated solution.
Exclusive Advantages for Ultrafine Clay Processing
1. Custom tailored grinding curve reduces over grinding of ultrafine powder and delivers high purity finished materials
Optimized grinding curved surfaces on grinding rollers and mill discs facilitate the formation of a stable clay material bed. Raw materials stay briefly inside the grinding chamber to avoid excessive pulverization from repeated compression. The finished powder contains extremely low iron powder impurities and kaolin products feature outstanding whiteness, meeting strict industry requirements of coatings, daily use chemicals and other sectors.
2. Multi-head variable frequency turbine powder separating system enables flexible adjustment of powder fineness
Multiple independently variable speed classifying rotors allow one single production line to manufacture ultrafine clay powder of various specifications such as 800 mesh, 1250 mesh and 2000 mesh, realizing multi-purpose operation for one machine.
3. Full-set intelligent automatic control cuts labour costs
Equipped with a PLC intelligent control system, the machine conducts real time monitoring over grinding pressure, chamber temperature, equipment vibration and hot air temperature. Remote maintenance is supported. The whole workflow including wet clay feeding, drying, grinding and classification runs automatically, and only a small number of on duty workers are needed for the entire production line.
4. Low vibration design, modular maintenance as well as energy saving and eco-friendly performance
Dual mechanical and electronic limit protection prevents hard collisions between grinding rollers and the grinding disc for low equipment vibration. Hydraulic outward turning rollers speed up the replacement of wear resistant spare parts. Fully enclosed negative pressure operation stops ultrafine clay dust leakage and satisfies clean production standards for high end powder processing plants.
