Anti-Crack Mortar Production Line

Anti-Crack Mortar Production Line
Product Introduction:
Crack-resistant mortar is a type of specialty mortar used to form a critical protective, crack-resistant layer over the insulation layer of external wall insulation systems. It effectively withstands temperature fluctuations, external impacts, and substrate deformation, fundamentally preventing issues such as cracking, hollow spots, or even detachment of the insulation layer, thereby ensuring the long-term structural stability of the system. The raw materials required include cement, sand, cellulose ether, redispersible polymer powder, crack-resistant fibers, and other chemical additives. The production line utilizes PLC-based computer control, ensuring high automation and clear visibility of every process step. Depending on the mortar's specific characteristics, either a twin-shaft paddle "zero-gravity" mixer or a ploughshare mixer is employed.

Product Introduction

Anti-Crack Mortar is a special dry-mixed mortar specially applied for building wall insulation systems and substrate protection. It is mainly used for surface protection of insulation boards and insulation layers, as well as anti-crack treatment for wall surfaces. Its core function is to improve the integrity and crack-resistance of the insulation system, and reduce cracking caused by temperature variation, substrate shrinkage and external stress.


Anti-crack mortar generally consists of cement, quartz sand or other graded sand, mineral fillers, together with functional additives such as redispersible polymer powder, cellulose ether and polypropylene fiber. Although fibers and functional additives are used in relatively small dosages, they exert great influence on crack resistance, bond strength, flexibility and workability of the finished product. Therefore, high requirements are placed on accurate batching and homogeneous mixing during production.

Product Features

1. Precise Batching for Stable Crack-Resistance
Equipped with high-accuracy dosing systems, the production line accurately meters cement, sand, fillers and small-dose functional additives to ensure stable formula ratios for every batch.


2. Homogeneous Mixing for Full Dispersion of Fibers and Additives
The high-efficiency twin-shaft gravity-free mixer achieves sufficient dispersion of various powders, sands and fibers. It reduces local agglomeration and uneven distribution of additives, so as to enhance the overall performance consistency of end products.


3. Preserve Fiber Structure and Minimize Production-Induced Damage
For reinforcing materials including polypropylene fiber and glass fiber contained in anti-crack mortar, conveying and mixing processes are optimized to lower excessive shearing and mechanical impact. This helps maintain fiber integrity and good dispersion effect.


4. Automated Production for Higher Efficiency
The production line realizes continuous and automatic operation covering raw material storage, conveying, dosing, mixing and finished-product packaging. It cuts manual intervention and improves both production efficiency and product quality stability.


5. Flexible Compatibility with Various Anti-Crack Mortar Formulas
It can produce different types of anti-crack mortar according to customers' formulas. Partial production equipment can be shared with other dry-mixed mortar products such as thermal insulation mortar, bonding mortar and plastering mortar, improving the overall utilization rate of the production line.

 

Production Process Flow

Drying → Lifting → Batching → Lifting → Mixing → Weighing & Packing

Drying

The wet raw materials are dried to reduce their moisture content to the required level for dry mortar production.

Lifting

The dried raw materials are conveyed and lifted into the corresponding storage silos by a bucket elevator or pneumatic conveying system.

Batching

According to the preset formulation, the raw materials are discharged from the silos and conveyed by screw conveyors to the weighing and batching bins for accurate weighing and proportioning.

Lifting

After all raw materials have been accurately batched, the weighed materials are lifted and transferred into the pre-mixing bin by a bucket elevator.

Mixing

The batched materials are discharged from the pre-mixing bin into the twin-shaft mixer, where they are thoroughly and uniformly mixed.

Weighing & Packing

After mixing, the finished dry mortar is discharged into the finished product bin and then fed into the automatic weighing and packing machine for accurate weighing and packaging.

 

Key Advantages

 

Labor-saving

The complete production and packing system can be operated with only 4 workers under normal working conditions.

 
 

Continuous Operation

The entire mixing system is designed for continuous and efficient operation, helping improve production efficiency and reduce downtime.

 
 

Accurate Batching

The automatic weighing and batching system ensures accurate material proportioning according to the required formulation.

 
 

Uniform Mixing

The twin-shaft mixer provides fast and homogeneous mixing, ensuring consistent product quality.
