This case study explores a strategic investment in a cement rotary dryer in Romania, a project that highlights how dedicated drying equipment can enhance production efficiency and product quality for regional building material suppliers.
Infrastructure development across Eastern Europe is creating a steady demand for high-quality construction materials.
This case study explores a strategic investment in a cement rotary dryer in Romania, a project that highlights how dedicated drying equipment can enhance production efficiency and product quality for regional building material suppliers. For companies in the construction sector looking to optimize their raw material processing, this Romanian installation offers valuable insights.
Our client operates a regional building materials production facility in the western part of Romania, near the Hungarian border. The plant specializes in producing dry-mix mortars, plasters, and specialized cement-based products for the local construction market.
Their process involves blending cement, fine aggregates, and various additives. A key challenge they faced was related to their fine sand supply. Locally sourced sand often had a high and variable moisture content, especially after rainy periods or during winter.
This moisture caused clumping in their silos, inaccurate batching in their mixing plants, and ultimately compromised the consistency and setting properties of their final products.
They needed a reliable solution to precondition their sand feedstock. The decision was made to purchase a single, dedicated rotary dryer for sand. This was not a replacement, but a new addition to their existing production line, installed upstream of their main storage and batching system to act as a raw material conditioner.
Name:
Cement Dryer
Country:
Romania
Date:
2025
Capacity:
Flexible
Model:
φ1.2*12
rotational speed:
3–12 rpm
inlet temperatures:
450°C
Target Moisture Content:
0.5–1%
The primary material to be processed is quartz sand, a key aggregate in their dry-mix formulations. The sand arrives with a surface moisture content that can fluctuate between 6% and 15%, depending on weather and storage conditions.
The client's objective is to consistently reduce this moisture to below 0.5–1%, creating a truly dry, free-flowing sand that ensures precise weighing, optimal blending, and superior final product performance.
Considering the client's production volume, which is substantial but not on the scale of a national cement plant, RICHI engineers proposed the φ1.2*12 rotary dryer.
This model offers an ideal balance of capacity and footprint for their operation. The 1.2-meter diameter and 12-meter length provide sufficient volume and retention time to effectively dry the fine sand particles without excessive dust carryover.
The unit's design allows for precise control of the drying curve through adjustable rotational speed (3–12 rpm). The system is configured to use a natural gas burner to generate inlet temperatures around 450°C.
The integration of this rotary dryer for cement plant sand preparation has become a cornerstone of the client's quality control strategy.
By ensuring constant ultra-low moisture content, they eliminated production variability. The cement rotary drying equipment guarantees optimal sand flow, preventing silo bridging and ensuring accurate batching.
This leads directly to more consistent mortar quality, improved workability for end-users, and fewer customer complaints. It also enables flexible sourcing of slightly damp sand at better pricing.
The entire sand drying system, including rotary drum, gear drive, combustion chamber, cyclone, and baghouse filter, was manufactured to order.
After factory testing, it was professionally crated and shipped from Qingdao Port via the Mediterranean and Bosporus to Constanța Port on Romania’s Black Sea coast.
Constanța provided efficient handling and customs clearance.
The client evaluated several European suppliers. RICHI was selected based on technical merit and value.
Key advantages included optimized internal flights for fine sand, robust sealing systems for thermal efficiency, and a customized dust collection solution combining cyclone and bag filter.
RICHI also provided detailed evaporation and fuel consumption projections specific to Romanian quartz sand.
"Adding the RICHI cement rotary dryer was a game-changer for our dry-mix quality. The difference in our sand flow is incredible—no more clogs, no more guesswork with moisture corrections.
Our mixing process is now vastly more consistent. The dryer integrates smoothly with our conveyors. Build quality feels industrial-grade.
The installation drawings were precise, and startup support was professional. They helped optimize temperature and speed settings for our specific sand.
For any building materials producer in Romania or nearby dealing with damp aggregates, investing in a dedicated rotary sand dryer like this one is a smart move."
While this application focuses on a cement rotary dryer in Romania for sand, rotary drum drying is widely used across many industries.
The machine handles high throughput, variable moisture, and abrasive materials efficiently.
RICHI provided full lifecycle support including site analysis, system layout, interface documentation, and after-sales service.
Each project is treated as a long-term partnership.
