A 300 TPD cement grinding plant is a medium-small cement production solution designed to produce approximately 300 tonnes of finished cement per day. It can serve regional cement markets, independent cement grinding stations, construction-material suppliers, and integrated cement plants that require additional grinding capacity.
Liming Heavy Industry can configure a 300 TPD cement grinding plant around an LM Vertical Roller Mill or a cement ball mill. The system can grind clinker with gypsum and suitable mineral additives such as limestone, slag, fly ash, pozzolan, or other approved cementitious materials. The final configuration depends on clinker grindability, cement type, target fineness, material moisture, available site area, local power supply, dispatch requirements, and long-term production plans.
300 TPD Capacity Overview
A 300 TPD cement grinding plant is designed to produce about 300 tonnes of finished cement each day. The required hourly output depends on the plant operating schedule. A project operating 24 hours per day requires lower hourly mill output than a plant operating one or two shifts.
| Operating Schedule | Approximate Required Finished Cement Output |
|---|---|
| 24 operating hours per day | Approximately 12.5 tonnes per hour |
| 20 operating hours per day | Approximately 15 tonnes per hour |
| 16 operating hours per day | Approximately 18.8 tonnes per hour |
| 12 operating hours per day | Approximately 25 tonnes per hour |
The selected grinding system should include a practical capacity margin. Actual mill output changes with clinker hardness, feed size, gypsum condition, additive proportion, target cement fineness, separator efficiency, material moisture, operating practice, and scheduled maintenance.
Typical Process Flow
The 300 TPD cement grinding process begins with clinker receiving and storage. Clinker is proportioned with gypsum and, where required, limestone, slag, fly ash, pozzolan, or other suitable additives. The materials are ground, classified, collected, stored in cement silos, and dispatched as bagged or bulk cement.
Receive clinker from trucks, railcars, ships, ports, or an on-site clinker production line.
Store clinker in a clinker silo, covered stockpile, clinker hall, or warehouse.
Store gypsum and mineral additives in separate storage areas.
Use belt weigh feeders or screw weigh feeders to proportion materials accurately.
Feed clinker, gypsum, and additives to the LM Vertical Roller Mill or cement ball mill.
Grind the material to the required cement fineness.
Classify fine cement and return coarse material for additional grinding where required.
Collect fine cement through a bag filter and dust-control system.
Convey finished cement to one or more cement silos.
Pack cement into bags or load bulk cement into trucks and other transport equipment.

LM Vertical Roller Mill Solution
An LM Vertical Roller Mill can be configured for a 300 TPD cement grinding plant where the project requires an integrated grinding and classification solution. Clinker, gypsum, and suitable additives enter the mill and fall onto the rotating grinding table. Grinding rollers apply controlled pressure to the material bed, reducing particle size through compression and shearing.
Process air carries the fine ground material upward to the integrated dynamic classifier. The classifier separates qualified fine cement from coarse particles. Fine cement exits with the gas stream and is collected by a bag filter. Coarse particles are rejected by the classifier and return internally to the grinding table for further grinding.
The LM Vertical Roller Mill provides a compact vertical configuration that combines grinding and classification in one main process unit. When suitable hot gas is available, it can also support drying and grinding of moist materials such as gypsum, limestone, slag, or other mineral additives.
LM Vertical Roller Mill Benefits
Integrated grinding and dynamic classification in one compact process system.
Suitable for clinker, gypsum, limestone, slag, fly ash, and other appropriate additives.
Compact vertical layout that can help reduce the required plant footprint.
No large steel-ball charge required for the primary grinding process.
Flexible cement fineness control through classifier speed and process adjustments.
Can support simultaneous drying and grinding when suitable hot gas is available.
Suitable for new cement grinding plants, blended cement production, and capacity expansion projects.
PLC-based process control for feed rate, grinding pressure, vibration, airflow, temperature, and power monitoring.
Cement Ball Mill Solution
A cement ball mill is a proven solution for a 300 TPD clinker grinding plant. It uses steel grinding media inside a horizontal rotating cylinder. As the mill rotates, the grinding balls are lifted by liners and then cascade onto the clinker, gypsum, and additives. The material is reduced by impact, friction, and attrition.
For cement production, the ball mill is normally arranged as a closed-circuit grinding system. The mill discharge is sent to a high-efficiency separator. Fine cement that meets the required fineness is collected as finished product, while coarse particles are returned to the ball mill for further grinding.
A ball mill grinding system can be a practical choice for projects that prefer a conventional grinding circuit or have existing ball mill foundations, buildings, conveyors, separators, and maintenance resources. Published cement grinding references show that ball mill circuits can be configured across a wide capacity range and are commonly used for clinker, gypsum, and additive grinding. [89]

The correct solution should be selected through a total project comparison. Important factors include equipment investment, civil works, power consumption, maintenance requirements, material properties, available installation area, product range, operator experience, local service conditions, and future expansion requirements.
Raw Materials and Cement Products
A 300 TPD cement grinding plant can produce different cement products by changing the ratio of clinker, gypsum, and mineral additives. The final formulation should be developed according to applicable cement standards, available raw materials, laboratory testing, target strength class, setting-time requirements, and local customer demand.
| Material | Function in Cement Production |
|---|---|
| Cement clinker | Main cementitious component that provides the primary strength-forming phases |
| Gypsum | Added to regulate cement setting behavior |
| Limestone | Used as a mineral addition in suitable blended cement products |
| Granulated blast-furnace slag | Used for slag cement and other blended cement applications |
| Fly ash | Used as a supplementary cementitious material where suitable |
| Natural pozzolan | Used in suitable blended cement formulations |
Finished Cement Storage and Dispatch
Finished-cement storage should be designed according to daily output, number of cement grades, dispatch method, production schedule, and local market demand. A 300 TPD plant may require one or more cement silos, depending on whether it produces a single product or several cement types.
The cement silo system may include aeration equipment, level indicators, pressure-relief valves, silo filters, discharge gates, air slides, screw conveyors, and flow-control devices. Separate silos are recommended when different cement grades must be stored without contamination.
For bagged cement, the plant can include a rotary packing machine, valve bag packer, bag conveyor, truck loading area, and warehouse space. For bulk cement, the plant can include bulk loading spouts for trucks, railcars, terminals, or other suitable transport systems.
Packing and loading capacity should be matched with the grinding output. If cement silos become full because dispatch is too slow, the grinding system may need to reduce output or stop even when the mill is operating normally.
Electrical and Automation System
The electrical system for a 300 TPD cement grinding plant must supply the mill main drive, process fan, separator, bag filter, conveyors, feeders, elevators, packing equipment, compressor, lighting, and control systems. The final installed power depends on the selected LM Vertical Roller Mill or cement ball mill configuration and the required auxiliary equipment.
PLC-based automation supports stable operation by monitoring material feed rate, clinker and gypsum proportion, mill motor power, grinding pressure, mill vibration, temperature, airflow, separator speed, bag filter pressure drop, cement fineness, silo level, and alarm status.
A central control room can improve plant visibility and operating consistency. It allows operators to monitor production performance, identify abnormal conditions, track energy consumption, control interlocks, and support preventive maintenance.
Integrated Clinker Production Option
A 300 TPD cement grinding plant can operate as a stand-alone unit by purchasing clinker from external suppliers. This arrangement can be suitable where clinker is available from nearby cement plants, ports, railway terminals, or established regional suppliers.
For projects requiring clinker production as well as cement grinding, Liming Heavy Industry can provide rotary kilns and calcining kilns. An integrated cement project can include raw-material crushing, raw meal grinding, preheating, calcination, rotary kiln processing, clinker cooling, clinker storage, cement grinding, cement storage, packing, bulk loading, dust collection, and automation systems.
When a kiln line is combined with a 300 TPD grinding plant, clinker production capacity, cooler output, clinker inventory, cement grinding capacity, finished-cement silo volume, fuel supply, electrical capacity, and dispatch equipment should be planned as one coordinated production system.
