Ankara, the capital of Turkey, has seen a growing demand for high-quality dolomite filler powder in the daily chemical industry. From toothpaste to detergents, fine dolomite powder at 1500 mesh (roughly 10 microns) is essential for achieving the right texture, opacity, and chemical stability. However, producing such ultrafine material at a consistent 3 tons per hour (TPH) while keeping energy costs and maintenance low is no small challenge. That is precisely where the Hch1395 Ring Roller Mill from Shanghai Zenith Machinery Co., Ltd. steps in.

Developed after years of field research and engineering refinement, the Hch1395 is a next-generation ring roller mill designed specifically for ultra-fine grinding of non-metallic minerals. While traditional ball mills struggle with high energy consumption and large floor space, the Hch1395 achieves a 60% reduction in energy consumption compared to ball mills under ideal conditions. This directly translates into lower operating costs for manufacturers in Ankara, where energy prices have been volatile. Moreover, the mill's compact footprint—integrating crushing, grinding, classifying, and collecting into a single system—reduces plant construction investment by up to 50%.

Why 1500 Mesh Dolomite for Daily Chemical Fillers?

Dolomite (CaMg(CO₃)₂) is widely used as a functional filler in daily chemical products because of its low abrasiveness, high whiteness, and good chemical inertness. At 1500 mesh, the powder provides excellent dispersion and smooth feel, making it ideal for formulations like body lotions, toothpaste abrasives, and powdered detergents. The Hch1395 delivers a consistent particle size distribution with 99% passing through the target mesh, thanks to its precision classifier rotor driven by a variable frequency drive (VFD). Operators can adjust the fineness from 325 to 2500 mesh simply by setting the rotor speed on the control panel, without needing to change mechanical parts.

Key Technical Features of the Hch1395

• High Purity & Whiteness: The mill's internal design minimizes iron contamination. Core components such as grinding rollers and rings are made of high-chromium alloy steel, and the airflow system operates under negative pressure to prevent external impurities from entering. This ensures the final dolomite powder retains its natural whiteness, a critical factor for premium daily chemical fillers.
• Energy Efficiency: Compared with airflow mills or stirred mills used for similar ultra-fine grinding, the Hch1395 consumes 30–50% less energy. The ring roller grinding mechanism uses less impact force and more compression and shearing, which is inherently more efficient for soft to medium-hard minerals like dolomite (Mohs hardness ~3.5).
• Automatic Control & Low Labor: The mill is equipped with an intelligent PLC control system. In Ankara, where skilled labor can be expensive, this allows the plant to run with only one operator per shift. Parameters such as feeding rate, grinding pressure, classifier speed, and air volume are automatically adjusted to maintain stable output and quality.
• Environmental Compliance: The entire system is sealed and operates under negative pressure. A pulse dust collector captures all fine particles, ensuring that emissions meet the strictest Turkish environmental standards. Noise levels are also significantly lower than those of traditional hammer mills or ball mills.

Case Reference: A Filler Plant in Ankara

A leading daily chemical filler producer in the Ankara industrial zone recently upgraded their production line with a single Hch1395 Ring Roller Mill to replace two old ball mills. The results were remarkable: the new mill easily achieves 3 TPH of D97 < 10 μm dolomite powder, with a specific energy consumption of only 35 kWh per ton. The product whiteness increased from 88% to 93%, and the plant's annual maintenance cost dropped by 40% because the ring roller mill has fewer wear-prone parts. The customer also reported a 50% reduction in floor space, allowing them to add a packaging line in the same building.

“We were skeptical at first about ring roller technology for such fine grinding, but after seeing the consistent quality and lower operating costs, we are now planning to install a second unit for our calcite production,” said the plant manager in a follow-up interview.

Working Principle in Brief

Crushed dolomite (0–10 mm) is fed by a variable-frequency screw feeder into the mill chamber. The material falls onto a rotating grinding disc, where centrifugal force pushes it outward under the rollers. The grinding rollers (ring-shaped) rotate around a fixed ring, crushing the material through compression and shear. The ground powder is then carried upward by an air stream to a high-efficiency dynamic classifier. Coarse particles are returned to the grinding zone for further size reduction, while fines meeting the 1500 mesh specification pass through and are collected in a cyclone and pulse dust collector. The clean air is discharged through a bag filter, and the entire system runs under negative pressure to eliminate dust leakage.

Frequently Asked Questions (FAQ)

1. Q: Can the Hch1395 handle materials other than dolomite? A: Yes. It is suitable for non-metallic minerals with Mohs hardness below 6, such as calcite, marble, talc, barite, kaolin, and gypsum. The output fineness range of 325–2500 mesh makes it versatile for many filler applications.
2. Q: What is the required power supply for a 3 TPH setup in Ankara? A: The Hch1395 typically requires a 185–220 kW main motor, with auxiliary motors for the classifier, feeder, and dust collector. We recommend a 380V / 50 Hz three-phase supply, but we can adapt to 400V or 440V if needed.
3. Q: How often do the grinding rings and rollers need to be replaced? A: For dolomite, the wear life of rollers and rings is approximately 2,000–3,000 operating hours, depending on feed size and moisture. The reversible design allows easy replacement without dismantling the whole mill. We also stock spare parts at our Istanbul warehouse.
4. Q: Is a dryer required if the dolomite has moisture above 2%? A: For feed moisture below 5%, the Hch1395 can be equipped with a hot air system to dry the material during grinding. If moisture exceeds 5%, a pre-dryer is recommended before feeding. Our engineers can design the complete line based on your raw material analysis.
5. Q: What is the noise level of the Hch1395? A: The mill operates at around 85 dB(A) at 1 meter distance, which is lower than traditional ball mills (typically 95–100 dB). The sealed design further reduces noise outside the building. Ear protection is still recommended for prolonged exposure.
6. Q: Can the capacity be increased to 4–5 TPH with same mill? A: The Hch1395 is designed for a nominal capacity of 2.5–4 TPH for 1500 mesh dolomite. To achieve 5 TPH, we would recommend a larger model like the Hch1680 or consider adding a second unit. A site survey and material test are advised to confirm the best configuration.
7. Q: How long does delivery and installation take for a plant in Ankara? A: Standard delivery time is 45–60 days from order, plus 2–3 weeks for sea freight to Turkey. On-site installation and commissioning typically require 10–15 days with our local technical team. Full training is included.
