Successful plant implementation by FLSmidth

Sarbottam Cement was the first project executed by FLSmidth in Nepal. It has several other firsts in Nepal like the first vertical roller mills for raw grinding and cement grinding, Expert Control System, Intelligent Motor Control Centre and Intelligent Network System.

With the increasing need for dams, bridges, housing projects and other infrastructure generating more construction projects, the demand for cement in Nepal is growing year on year. Cement manufacturers are looking to build new plants in order to expand cement production capacity.

In a move that reflects this demand, the Saurabh Group awarded the Sarbottam Cement Plant´s project in Nepal to FLSmidth during the year 2012. The first contract awarded on FLSmidth was for the supply of a clinker production line. This is the first full-scope supply of equipment undertaken by FLSmidth in Nepal.

Clinker production line: Scope of supply
The project supply included everything from the crusher and mills (raw & coal) to pyro-processing, electrical systems and automation as listed below.

òLimestone crusher (Impact - 480 kW)
òLimestone stacker (luffing) & bridge reclaimer, material handling equipment
òRaw mill grinding ATOX 30 & 32.5 RAR air separator
òRaw mill & coal mill bag house & cooler ESP
òFRF silo (16 x 28 m)
òPreheater: 5-stage single string ILC
òRotary kiln (3.15 x 47 m)
òClinker cooler: FLSmidth Cross-Bar® Cooler 6 x 29 with clinker breaker
òCoal mill TIRAX® ball mill (TM30 x 4.5 + 2.30) with air separator RTKM 17.5
òElectrical, automation & instrumentation items (from 33 kW incomer to control system complete design and supply)

"Even as the project execution was going on, we could see that FLSmidth´s team was fulfilling their commitment of lowest thermal and electrical energy consumption, and also honouring the trust that we placed in them through their meticulous planning, effort and cooperation," says Bishnu Prasad Neupane, Managing Director of Sarbottam Cement.

"This project was planned in such a way that there were no hurdles at site for want of drawing or materials, which relieved us of stress and saved our time in follow-up activities with the supplier" adds Bimal Kumar Sawarthia, Finance Director of Sarbottam Cement.

Confidence reposed on FLSmidth with an order for cement grinding system Appreciating FLSmidth´s supply and execution of the clinker production line, Sarbottam Cement immediately issued an order on FLSmidth for a cement grinding system also, and the project got effective since August 2014.

Major equipment supplied under the contract for cement grinding system were:

  • Gypsum Crusher: 75 t/h
  • VRM OKTMT 25-3 (1300 kW): 70 t/h
  • Air Separator ROKSH 50: 146 rpm
  • Bag Filter (Jet Pulse): 185,400 m3/h
  • 8-spout packing and loading machine: 2,400 bags/h (or) 120 t/h
  • All Auxiliary Equipment
  • Complete plant Electrical & Automation

The OKTMT vertical roller mill was successfully commissioned on 30th May, 2016. The 1200 tpd cement plant is located about 50 km from Lumbini, the birthplace of the Buddha.

Several ´firsts´ in Nepal
In addition to the fact that Sarbottam Cement is the first project for which equipment is supplied by FLSmidth in Nepal, the Sarbottam Cement plant provides the first ATOXTMT vertical roller mill for raw grinding and OKÖ vertical roller mill for cement grinding at a cement plant in Nepal. Moreover, it is the first Expert Control System (ECSTMT), Intelligent Motor Control Centre (IMCC) and intelligent network system to be installed in Nepal as well. Sarbottam Cement has also installed Nepal´s first thermal power plant.
