State of the art technology

Carthage Cement is equipped with state-of-the-art equipment, enabling it to ensure smooth processes, easy handling and a cost-effective production.

1. Crusher

The raw material is fed into a hammer and impact crusher (type EV) through two separate vane distributors in order to bring the two mixtures according to the predetermined set of instructions.

Caractéristiques
Conception / spécifications
Concasseur EV 200X300
Débit de production 1300 t/h
Alimentation (dim max) 1500 mm
Production (dim) Max 5% +96 mm

2. Raw crushing (ATOX)

For crushing raw materials, a Vertical ATOX vertical mill is used.

The ATOX raw material mill uses the pressure and the generated shear between the rollers and the turntable to crush and pound the raw materials. The feed material is directed onto the grinding table by the feed chute. The rotation of the grinding table accelerates the material towards the grinding track and passes it under the rollers.

The gas passing through the mill reaches the separator (type RAR-LVT) with very high separation performance.

5. Preheater, calciner and oven

Preheater :
The chosen configuration offers an energy-saving solution that takes into account the moisture content of the raw meal as well as the tower dimensions.

Online Calciner:
On-line calciners have lower NOx emissions than in-line calcination furnaces, since all exhaust gases from the furnace must pass through calcination.

Oven with three supports:
The 3-base oven is a high-quality rotary oven with three traditional supports.  

Duoflex burner:
The DUOFLEX ™ burner triggers rotary ovens with pulverized pet-coke, natural gas or any mixture of these fuels.
The DUOFLEX burner is unique. It in fact carries a central duct for gaseous and liquid fuels placed inside an annular coal duct.

9. Bagging Unit 

Each bagging unit has the following characteristics:

  • Cement is transported through a bucket elevator to a screw conveyor to the bagger.
  • The machine is equipped with 08 rotary nozzles with an automatic or manual applicator.
  • Each filling nozzle is equipped with its own vertical axis propeller and an electronic weighing system including automatic weighing control.
  • Each bagger is connected to two forklift trucks that feed two loaders in parallel so that there’s permanently a truck for loading in order to maintain the line of conditioning with high efficiency.
