Plastering Mortar Production Line

Role：Dry sand and gravel raw materials, reduce material moisture content, avoid caking and failure of sensitive admixtures, and guarantee the flow and leveling performance of self-leveling mortar. Key Selection Criteria：Adapt to dry mortar drying conditions with low particle degradation, precise temperature control, excellent air tightness and high thermal efficiency; equipped with wear-resistant inner liner to match overall production capacity.

Role：Filter impurities and oversized particles, grade sand materials to optimize aggregate gradation, prevent coarse particles from affecting mortar quality and damaging subsequent precision equipment, and ensure raw material uniformity. Key Selection Criteria：Adopt fully enclosed dust-proof structure, equipped with wear-resistant and anti-clogging screen mesh; feature high screening efficiency and stable grading accuracy to meet fine batching standards for self-leveling mortar.

Role：Vertically transport dried and screened powders and sand to pre-mixing hoppers and silos, ensure continuous material supply; enclosed conveying effectively reduces particle degradation and segregation. Key Selection Criteria：Adopt enclosed chain-type design with gentle low-speed handling to prevent particle damage; equipped with wear-resistant buckets, good sealing and anti-deviation & anti-blocking protection devices.

Role：Store bulk materials such as cement, gypsum and special fillers with moisture and dust protection, ensure continuous and stable material supply for the production line. Key Selection Criteria：Capacity matches production volume; prioritize humidity control and anti-bridging devices for gypsum-containing materials; equipped with level monitoring and top dust removal system with anti-corrosion inner wall.

Role：Complete horizontal material transfer between process stages, stably convey raw materials from silos to metering equipment and mixers, and realize uniform feeding with minimal segregation. Key Selection Criteria：Adopt U-trough structure with Hardox 450 wear-resistant lining and anti-segregation design; stainless steel material for material contact parts with excellent sealing performance for powder conveying.

Role：Realize ultra-precise automatic batching for main materials (cement, sand, gypsum) and micro-additives (cellulose, superplasticizers, defoamers) to ensure consistent formula and batch-to-batch product stability. Key Selection Criteria：Main material batching accuracy: ±0.2%; micro-additives adopt loss-in-weight feeders and anti-bridging micro-screw feeders with ±0.1% high precision; full stainless steel structure for multi-formula precise batching.

Role：As the core equipment of the production line, it homogeneously blends all ingredients, preserves the functional integrity of sensitive components and particle size distribution, and ensures the excellent flow and leveling performance of finished mortar. Key Selection Criteria：Adopt high-shear twin-shaft paddle structure with gentle yet intensive mixing effect; optimized blade design for special mortar formulations; Hardox 500 carbide overlay wear-resistant parts with complete discharge capacity and homogeneity coefficient CV ≤ 2%.

Role：Serve as buffer storage before packaging, maintain finished product uniformity, avoid secondary material segregation, and ensure continuous and stable packaging operation. Key Selection Criteria：Equipped with fluidized bottom and anti-segregation cones, with real-time level monitoring device for continuous automatic production.

Role：Automatically fill finished self-leveling mortar into valve bags with precise weighing, realize automatic packaging, and avoid material segregation and dust pollution during packaging. Key Selection Criteria：Valve bag packing capacity: 25-40 bags/hour with ±0.1% weighing accuracy; integrated dust collection and anti-segregation feeding design to ensure consistent product quality after packaging.

Role：Automatically stack filled mortar bags on pallets in standard and precise patterns, facilitate storage and transportation, reduce labor cost and maintain bag integrity. Key Selection Criteria：Robotic palletizer is suitable for high-volume lines with capacity of 400-800 bags/hour; gentle handling design to avoid bag damage with accurate and stable stacking effect.

Role：Serve as the overall supporting frame of the production line, carry all main equipment such as silos, mixers and conveying equipment, fix equipment layout, ensure stable operation and accurate installation, and provide safe operating platforms. Key Selection Criteria：Adopt national standard load-bearing section steel with high safety factor, suitable for tower-type production line layout; overall anti-corrosion and weather-resistant design with complete anti-slip platforms and safety protection facilities to meet industrial safety production standards.

Role: Collect dust generated from each production process, prevent dust leakage, purify working environment, reduce material loss and meet environmental emission standards. Key Selection Criteria: Adopt pulse bag type with high dust removal efficiency. Match air volume of production line, wear and corrosion resistant filter bags. Good sealing performance, convenient ash cleaning and qualified exhaust emission.
