The MMT industrial ovens work using heat and mass transfer using direct heat from gas oil burner or indirectly through a heat exchanger system. The types of oven that MMT produce include:
- Batch oven – used to process materials in individual batches,
- Conveyor oven – used to move products through a heating chamber on an automated conveyor belt,
- Drying oven – used to remove excess moisture from raw materials, and
- Rotary dryer – used to minimize the liquid moisture content of the material; is made up of a rotating cylindrical tube, usually supported by concrete columns or steel beams. The dryer is inclined to slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under gravity.
