- Welded: Accurately arrange the position of the steel mould and motor seat.Put 6 rebar (Φ 24) inside of each steel die (2 steel mould); Four corners of the motor base stand up and 1 rebar(Φ 18). Each rebar is 50 cm higher than the horizontal plane.
- First pouring concrete: The height is the same as the floor.
- Placing main machine steel die: The next day, Placing the main machine steel mould according to the size of the basic drawing.
- Weld: After the steel mould is put in place and make sure all sizes are correct. Weld the steel mould with 6 rebars (Φ24) together.
- The second pouring concrete. When pouring, the first steel mould is pouring half, and then poured another half of the steel mould, then back to pouring the first steel mould. It ensures that the size comparison does not deviate.Attention
- A single steel mould must be horizontal, at the same time, two steel mould dies must be horizontal.
- The pitch-row of the foundation bolts of two steel mould must be accurate. SHM-309 roller mill is 2045mm.
- Two steel mould cannot be misplaced.（It can be corrected by diagonal lines between steel dies, the length of diagonal must be equal.）
- The center line between steel mould and motor seat must be accurate. SHM-309 roller mill is 1900mm.
- After the steel mould is put in place and make sure all sizes are correct, the two steel mould must be welded and fixed with three channels steel before pouring concrete. Make sure the steel mould is not displacement and dimension not error during pouring. (This step must be done.)
What is Light calcium grinding mill?
A light calcium grinding mill is a specialized industrial pulverizer purpose-built for processing light calcium carbonate, a low-density, high-whiteness non-metallic mineral product.
Unlike general ore mills, it uses optimized low-impact, high-shear grinding structures to break up easily agglomerated light calcium particles without causing excessive over-grinding or whiteness loss.
It can stably produce powders from 325 mesh to 3000 mesh, with a narrow, uniform particle size distribution.
Widely used in light calcium production lines, it delivers high-quality fine powder for plastics, coatings, papermaking and food additive industries.
What is the Light calcium grinding process?
The light calcium grinding process is a tailored workflow for processing precipitated calcium carbonate.
First, pre-dried light calcium raw material is fed evenly into the grinding chamber, where agglomerated particles are dispersed and crushed via controlled shear and low-impact forces.
The ground fine powder is carried by airflow to the integrated high-precision classifier, which separates particles meeting target fineness for collection.
Oversized coarse agglomerates are returned to the grinding zone for reprocessing.
This closed-loop operation avoids over-grinding, preserves product whiteness, and delivers uniform, high-quality fine powder for downstream industrial applications.
What are the uses of Light calcium grinding mill?
Light calcium grinding mills are purpose-built for processing precipitated calcium carbonate into high-value fine powders.
They produce 325–3000 mesh light calcium powder used as high-performance filler in PVC, rubber, coatings and ink industries, improving product smoothness and dimensional stability.
They also make ultra-fine light calcium for papermaking, boosting paper opacity and printability, and food/pharmaceutical-grade fine powder for toothpaste, cosmetics and medicine additives.
The mills effectively disperse agglomerated particles, ensuring consistent powder quality to meet strict industrial standards.
What is the best Light calcium grinding process?
The best light calcium grinding process is a closed-loop wet-dry combined optimized workflow.
It first adds a small amount of dispersant to pre-disperse the light calcium slurry, then uses a vertical sand mill for fine grinding to reach the target particle size, followed by secondary carbonization to adjust crystal morphology.
After low-temperature drying, the material enters a high-precision ring-roller mill for final depolymerization and classification.
This process avoids over-grinding, preserves product whiteness, delivers narrow particle distribution, and is widely recognized as the most efficient route for high-grade light calcium production.
Light calcium grinding process Application：
The optimized light calcium grinding process is widely applied across multiple high-value industrial scenarios.
It produces 800–2500 mesh fine light calcium for PVC, PE and rubber fillers, enhancing material tensile strength while cutting production costs.
It also manufactures ultra-fine light calcium for architectural coatings and water-based inks, delivering excellent suspension performance and high covering power.
Additionally, this process supports food and pharmaceutical grade light calcium production, meeting strict hygiene standards for additives in toothpaste, calcium supplements and cosmetics.
Light calcium grinding Processing Technology：
Light calcium grinding processing technology is a specialized pulverization technique tailored for precipitated calcium carbonate.
It adopts low-shear, high-dispersion grinding modes to break up agglomerated particles without damaging the original crystal morphology, effectively avoiding over-grinding that reduces product whiteness.
The process integrates online particle size monitoring and closed-loop classification, allowing continuous adjustment of grinding force and airflow parameters.
It can stably produce light calcium powder ranging from 325 mesh to 3000 mesh, with narrow particle size distribution, high whiteness, and excellent dispersibility for downstream industrial applications.
Guide to Light calcium grinding: Mills, Tips, and Uses
This practical guide covers light calcium grinding essentials, core mill types, operation tips and key uses.
Recommended mills include specialized ring-roller ultrafine mills for large-volume production, and horizontal sand mills for high-grade nano-scale light calcium.
Key tips: strictly control raw material moisture below 1.5% to avoid agglomeration, adjust classifier speed to lock target fineness, and use non-metallic grinding media to prevent whiteness loss.
This process produces high-quality light calcium powder widely used in plastic fillers, architectural coatings, papermaking additives and food-grade calcium supplement production.
What is the auxiliary equipment in a Light calcium grinding mill plant？
The auxiliary equipment in a light calcium grinding mill plant forms a full supporting system for stable, high-quality production.
It includes vibrating feeders that evenly deliver pre-dried raw materials, bucket elevators for material conveying, and high-precision dynamic classifiers that separate qualified fine powder.
It also features cyclone collectors, pulse dust collectors, induced draft fans, and automatic powder packaging machines.
Additional supporting parts include raw material silos, cooling systems, and online whiteness monitoring devices, which prevent over-grinding, reduce dust leakage, and ensure consistent final powder quality.
How to optimize Light calcium grinding mill grinding efficiency?
You can optimize light calcium grinding mill efficiency through targeted, material-specific adjustments.
First, strictly control feed moisture below 1.5% to reduce agglomeration that blocks grinding chambers.
Second, operate the mill at 65-75% of its critical speed to prioritize gentle abrasion over harsh impact, avoiding over-grinding and whiteness loss.
Third, adjust classifier speed and airflow to promptly return unbroken agglomerates for reprocessing.
Finally, add a small amount of stearic acid coating during grinding to reduce particle adhesion, boost throughput by 15-20% and cut energy consumption significantly.
