GENERAL INFO

Following the Light Asset Strategy concept, SINOMA-CBMI in partnership with Globbulk have developed a low cost and EPC/Turnkeysolution for clinker grinding plants: the Modular Mobile Grinding (MMG) system.

This concept allows to quickly capture opportunities for developing or penetrating small and mid-size markets.

WHY MODULAR GRINDING PLANTS?

This modular solution has a number of advantages, highlighted in the following bullet points:

  • - Ideal for capturing markets of up to 500,000 tpy.
  • - Suitable for greenfield or brownfield projects.
  • - Delivered on an EPC contracting approach.
  • - Based on a strip-down concept, which focuses on the core needs of the operation.
  • - Reduced CAPEX, with a shorter payback.
  • Fast-track project implementation: with a single partner from order to delivery, and accelerated market entrance (earlier positive cash flows).
  • Proven technology: you can select between a horizontal ball mill or a vertical roller mill.
  • - Production in closed circuit.
  • - Light facilities, which typically require shallow foundations.
  • Container-size equipment for easier transport and erection.
  • - Modularization, which also facilitates the dismantling and re-erection elsewhere if commercial conditions change.
MODULARIZATION WITH FLEXIBILITY

Modularization does not imply "one solution fits all". It rather means that with a number of standard elements many solutions can be found by intelligent combinations.

Neither all the components of the plant need to be modular and containerized: raw material reception and storage areas typically follow their own modular optimization.

The Client's requirements on number of raw materials and cement types can be easily solved, and the strip-down approach can also be relaxed to match the Client's preferences.

EARLY MARKET ENTRANCE AND FAST RECOVERY OF INVESTMENT.

The time to market entrance is often critical, and the Client can hardly wait 18 months to start selling his cement.

Standardization, modularization and EPC contracting all push in the same direction: quick project execution time in order to start production within less than 12 months. A delay of 1 month can easily imply a lost cash flow of around 1 million USD!.

LOW COST VERSUS CHEAP

Sinoma-CBMI have more than 60 years of experience in building and operating cement plants, and integrate the best international suppliers of equipment into their projects, always following the Client's list of approved or preferred suppliers.

The Client benefits from cost savings that arise from Sinoma's purchasing power, standardization, modularization and professional solutions, not from buying cheap equipment.

TECHNICAL SPECS OF THE CEMENT GRINDING DEPARTMENT

Typical technical specifications of the proposed solutions include:

  • - Power supply: MV 6.3 kV or LV 400V
  • - Environmental specifications: Dust emissions <30 mg/Nm3 / Noise emissions: <85 dB inside buildings and <50 dB outside
OTHER DEPARTMENTS

The design of the different plant departments is done to match the specific requirements of the Client's project, but they typically include:

  • - Raw materials shed, with capacity calculated according to the conditions of the supply chain and sales market.
  • - Feed bins to mill: often 3, for clinker, gypsum and other additives, but the number can be easily adjusted.
  • - Cement silos: standardized to 1,000 t each. The total storage capacity to be calculated according to product portfolio and market demand.
  • - Packing plant: which can use rotary or in-line packers.
  • - Bags truck loading: often by overhead leaning loader, but sometimes even with palletizers and bagged cement storage.
  • - Bulk loading: underneath the cement silos, with integrated weigh-bridge.
  • - Weighbridges at the main gate, for inbound and outbound weight control.
  • - Auxiliaries: compressed air and industrial water as required.
  • - Electric equipment: from the different transformers at MV or LV, the power distribution and protection sections, power factor correction, receivers, MCC, cabling, instrumentation, process control, lighting, lightning protection, emergency power supply or power generation, as required.
  • - Infrastructure: domestic and industrial water supply and treatment, roads and parking, water-storm and drainage, fencing, also landscaping and maritime infrastructure if needed.
  • - Buildings: raw materials in shed-type building, offices, labs, stores, etc. in modules.
