In the world of construction, masonry mortar and plastering mortar are two of the most essential materials used in dry mortar applications. This guide provides detailed insights into their formulations, the importance of raw material selection, and the equipment required for efficient production.
1. Masonry Mortar Formulation
Masonry mortar is primarily used for the construction of walls. The typical formulation includes:
- Cement (425#)
- Dry sand (with varying particle sizes, including 0.5mm, 1mm, and 3mm)
- Fly ash
- Cellulose ether (HPMC)
- Redispersible polymer powder (VAE)
Key Considerations:
- The use of coarse sand (around 5mm) is crucial for providing compressive strength and preventing deformation during bricklaying.
2. Plastering Mortar Formulation
Plastering mortar is used for the plastering and leveling of walls after masonry work is completed. The formulation includes:
- Cement (425#)
- Medium to fine dry sand
- Fly ash
- Cellulose ether (HPMC)
- Wood fibers
- Redispersible polymer powder (VAE)
Key Considerations:
- Unlike masonry mortar, plastering mortar does not require coarse sand. The addition of fly ash helps to reduce costs while improving workability and ease of application.
3. Dry Mortar Production Equipment Overview
A typical dry mortar production line is designed to handle capacities ranging from 20 to 80 tons per hour. These systems are often equipped with:
- Bulk material systems for efficient transportation and storage.
- Sand drying systems (optional, depending on raw material availability).
- Automated batching and mixing systems controlled by a PLC system.
Production Process:
- Raw Material Storage: Cement and fly ash are stored in separate silos.
- Batching and Mixing: The materials are automatically weighed and batched for precise mixing. The mixing process typically takes less than 2 minutes per batch.
- Finished Product Storage: The mixed mortar is stored in silos and can be directly loaded into mortar trucks for transportation.
4. Key Equipment Details
The production line includes critical components such as:
- Double-Axis Paddle Gravity-Free Mixers or Plough Mixers for thorough mixing.
- Screw Conveyors for precise material transportation.
- Pulse Dust Collectors to manage dust throughout the production process.
5. Optimizing Your Dry Mortar Production
Investing in advanced equipment such as high-efficiency bucket elevators, pneumatic conveying systems, and fine screw conveyors can significantly enhance production efficiency. For businesses that require customized solutions, various configurations can be tailored to meet specific production needs.
