DRY MORTAR INSTALLATIONS

SOTECMA designs, manufactures and supplies turnkey installations for the manufacture of dry mortar, cement glue, technical mortars, repair, self-leveling, monolayer color, etc.

Dry mortar fabrication plants specifications

The main characteristics are:

• Tower or semi-tower type.
• Productions up to 150 t / h.
• Reception and classification of aggregates (optional).
• Possibility of using a wide range of chemicals additives.
• Raw material silos from 40 m³ to 400 m³ per unit.
• Big range of final products available

A dry mortar plant basically consists of a system of silos, for the collection of raw materials (aggregates, cement, lime, additives …) and from these silos the raw materials are dosing and weighting; after that are fed to a mixer, where are mixed with the exact composition of the requested mortar. The final product can be supplier by bags, big bags and tank truck.

Dry mortar fabrication plants

The installation of a dry mortar fabrication plant is equipped with:

MAJORITY RAW MATERIALS (AGGREGATES AND CEMENTS)

These products are the main components in volume, more ha 95% of the dry mortar composition. The silo load of cement, lime and filler, in general all the fines, is carried out by means of a pneumatic system, from the tank truck that transports them.

The loading of the aggregate is carried out through a reception hopper, where the trucks will unload, it transports it to a bucket elevator that elevates it to a distribution system formed by gutters, screens and augers that deposit it classified in each silo.

ADDITIVE SILOS

Like the majority components, the additives are also stored in silos. Usually 2 groups of silos are constituted, one of greater capacity for the majority additives, and another of smaller capacity for the minority additives. The loading of these silos is done manually, since the additives are normally purchased in bags or big-bags.

SYSTEM OF DOSING AND MIXING OF THE MATERIALS

Once the process of storing the raw materials is finished, the operator selects the formula and quantity of the material that is to be manufactured from the computer program, to which previously the corresponding formulation has been introduced.

The software system, will inform in real time of the situation of the order, as well as stock of raw material and finished product. From each silo the material is dosed by means of screw conveyors to the weighing hoppers, which in turn discharge onto the mixer.

In the case of additives, each of the silos has a micro dosser that is responsible for providing the material in a controlled way to the precision weighter patented by SOTECMA.

From the weighing is done, the additive will be unloaded on a pneumatic transport system that will take it directly to the mixer. When the mixer is filled with all the selected and heavy materials, the mixing process begins. After the mixing process, the final product is ready for transport, silage or bagging.
