Calcium carbonate mill for 10 tph production in India

Growing Demand for Ground Calcium Carbonate in India

India is one of the fastest-growing markets for ground calcium carbonate (GCC), driven by expanding paper, paint, plastics, rubber, and adhesive industries. Calcium carbonate adds whiteness, improves surface finish, and helps manufacturers lower raw material costs. In India, high-quality limestone and marble deposits are located in several mineral-rich regions, making local milling a rational and profitable business. For producers targeting a plant output of 10 tph, the selection of the grinding mill is central to project economics. The ideal calcium carbonate mill must handle the feed size, keep a stable product fineness, use low power, and offer long service life under continuous duty.

Shanghai Zenith Machinery Co., Ltd. is an excellent manufacturer of ore grinding equipment in China and has made great achievements in the field of ultra-fine powder grinding. Zenith supplies a complete range of grinding equipment for limestone, calcium carbonate, barite, dolomite, coal, cement raw meal, and many other minerals. Its research, development and production teams provide mills that combine innovative technology with practical operation experience.

Key Selection Criteria for a 10 TPH Calcium Carbonate Mill

Not every mill rated at 10 tonnes per hour can perform successfully in an Indian GCC project. The final choice should consider the following factors:

• Feed size: material from the jaw crusher should be under 35 millimetres for models such as the MTW138Z. Oversize particles create unstable operation and lower capacity.
• Hardness and abrasiveness: limestone hardness, silica content and abrasion index affect wear parts and maintenance intervals.
• Moisture content: feed moisture above about 6 percent may require a hot air drying system or pre-drying in order to maintain capacity and avoid blocking.
• Required fineness: some customers produce 200 mesh coating powder while others require 325 mesh filler or even finer grades. The classifier speed must be adjustable within a practical range.
• Availability of power: 10 tph lines need adequate installed power and stable voltage. Energy-efficient design lowers monthly cost.
• Dust emission: Indian environmental rules encourage closed-circuit milling with pulse bag filters. A clean plant improves worker safety and community acceptance.

Zenith takes these parameters into account when recommending a calcium carbonate mill.

Zenith MTW Trapezium Grinding Mill for 10 TPH Calcium Carbonate Production

Shanghai Zenith recommends the MTW Trapezium Grinding Mill for GCC plants with a target capacity of around 10 tph and a standard filler fineness range. The MTW series is a multi-patented mill developed for medium and high capacity powder production. Its compact structure, internal circulation and low power consumption make it suitable for Indian calcite and limestone processing.

For this capacity range, the MTW138Z is an excellent balance between price and performance. It is designed to accept a maximum feed size of 35 millimetres and can grind to a final product size of 0.045 to 1.6 millimetres. The mill’s capacity range of 6 to 17 tonnes per hour leaves enough margin to operate steadily at 10 tph when the raw material is normal limestone. The main motor rating is 90 kilowatts while the fan motor is 110 kilowatts, which is moderate for a plant of this output.

The MTW mill uses a bevel gear integrated system, a curved shovel, pendulum roller assembly and a self-sealing classifier. It has become popular because a plant can change from one mesh specification to another by adjusting the classifier rotor speed. For a calcium carbonate mill in India, this flexibility allows producers to serve both local construction and industrial filler markets.

The LUM Ultrafine Vertical Mill as an Alternative for High-Value Fine Powder

Some producers in India do not want 200 mesh or 325 mesh powder only. They sell higher-value GCC grades for paper coating, PVC masterbatch, rubber and speciality paints. If the required product is much finer, for example with D97 between 5 and 30 micrometres, Zenith can offer the LUM Ultrafine Vertical Mill. The LUM1836 model has a capacity of 2.3 to 15 tonnes per hour and a main motor power of 355 to 400 kilowatts. It integrates grinding, drying, classifying and conveying in one unit, saving floor space and simplifying the process. With intelligent control and a vertical arrangement, LUM is recommended when a 10 tph line must produce very fine calcium carbonate with consistent size distribution.

Between MTW and LUM, the correct choice depends mainly on target fineness and investment value. For ordinary GCC fillers in India, MTW138Z is economical, proven and easy to operate. For more sophisticated markets where finer powder commands a premium price, LUM is a strong candidate.

Typical Plant Configuration Around the Mill

A complete calcium carbonate plant for 10 tph involves several components arranged around the main grinding machine. Raw limestone is first crushed by a jaw crusher, then lifted to a raw material silo. A vibrating feeder controls the flow into the mill. Inside the MTW mill, rollers and grinding rings perform the size reduction. A high-efficiency air classifier separates fine powder from coarse particles, and oversize material is returned for further grinding. Fine powder is carried to the cyclone collector and then to a pulse-jet bag filter. The bag filter collects ultra-fine dust and ensures that exhaust air is clean. The finished powder is conveyed to a silo for packing or bulk tanker loading.

Zenith can also supply the entire system, including belt conveyors, bucket elevators, silos, screw conveyors, dust collectors, electrical control panel and installation supervision. This single-source approach is important for 10 tph projects because equipment compatibility, size and process control need to be designed together rather than assembled from different suppliers.

Why Indian Producers Choose Zenith Calcium Carbonate Mills

Indian buyers evaluate machinery on the basis of recovery time, spare parts availability and technical advice. Shanghai Zenith has an extensive line of powder grinding equipment, including the MTW Trapezium Grinding Mill, MTM Medium-Speed Grinding Mill, Raymond Mill, LM Vertical Grinding Mill, LUM Ultrafine Vertical Mill, XZM Ultrafine Grinding Mill, Hammer Mill and Ball Mill. This broad portfolio allows a distributor or project consultant to select the exact machine for the local material.

Zenith also offers complete installation engineering, process flow design and after-sales support. The wear parts and grinding rolls are produced with high-quality steel alloys, and the classifier, lubrication system and reducer are selected for continuous mineral grinding work. In a country like India, where operating temperatures can be high and power quality varies between areas, robust mechanical design is as valuable as capacity.

Conclusion

For 10 tph calcium carbonate production in India, the calcium carbonate mill should be selected only after studying the feed material, required fineness and plant economics. The MTW Trapezium Grinding Mill, especially the MTW138Z model, provides a reliable and cost-effective solution for normal limestone powder grades. For finer GCC powders, the LUM Ultrafine Vertical Mill gives an advanced option. By choosing Shanghai Zenith Machinery, mineral processors gain access to proven grinding technology, high manufacturing quality and professional engineering support.
