The dry mortar production line consists of two major systems: drying and mixing. Below we mainly introduce the drying system of the dry mortar production line. Our company can configure the process and equipment according to the actual conditions of different users.

  The early part of the complete set of dry mortar production line is the drying system. Our company's drying system is configured according to the actual situation of the user. The fuel can be coal, natural gas, liquefied gas, diesel, biomass fuel, etc. Sand drum dryer can be configured according to the user's raw material conditions. Regardless of the single-cylinder rotary dryer or the three-cylinder dryer, the moisture content of the material after drying can be controlled below 0.5%, which meets the sand requirements for dry powder mortar. The following is the working process of the drying system:

  1. Large pieces of material are fed to the hammer disperser at a constant speed through the raw material bin. The hammer disperser can initially break wet materials below 25cm to below 3cm;

  2. The crushed and dispersed materials are transported to the sand drum dryer through the belt conveyor. After the body rotates at nearly 600 degrees Celsius, the materials and the heat source are fully contacted, the water is evaporated, and is discharged through the induced draft system. Equipped with a Shakron dust collector, it can effectively reduce dust pollution and collect part of the fine materials that are led away. After the material is dried, the final moisture content will be reduced to less than 1%. Through natural evaporation and subsequent processes, the final moisture content will reach Below 0.5%, it meets the water content requirements of sand for dry mortar;

  3. The dried materials are transported to the compound crusher through the belt conveyor. The compound crusher will finely crush the drying materials below 3cm through four layers, so that the particle size of the finished product reaches the mortar sand standard of 4-100 mesh. This stage can By adjusting the speed of the compound crusher equipment, the proportion of each particle size of the finished product is controlled;

  4. After the material is finely crushed, it passes through the vibrating screen equipment to screen out unqualified impurities, large pieces and fine powder. Different mortar types require different raw material particle size ranges. Through the previous stage of crushing particle size control and simple replacement of the screen, , which can realize the supply of raw materials according to the particle size range.

  In the drying stage, the equipment can be configured according to the specific conditions of the materials. You can choose a single-cylinder drum dryer or a three-cylinder dryer. If you are interested in our sand drying production line, please contact us.
