Semi-Automatic Dry Mortar Production Line

The semi-automatic dry mortar production line is a solution between manual simple lines and fully automatic lines. Its core feature is manual-assisted batching with automatic mechanical mixing and packaging, balancing investment cost, production efficiency, and operational flexibility. It is ideal for small and medium-sized mortar plants.

Output: 20 – 50 tons per day

Product Structure

Essence: Upper storage → Middle metering → Core mixing → Lower buffer & packaging + Full-process dust control

Six Core Modules

1.Feeding & Conveying System

1. Manual feeding hopper (with dust port)
2. Bucket elevator (vertical feeding)
3. Screw conveyor (bottom discharge)
4. Manual feeding port for minor ingredients

2.Raw Material Storage System

1. Main silos: sand silo, cement silo, fly ash silo (vertical cylindrical silos)
2. Additive silos: micro-ingredient silos for cellulose ether, rubber powder, fiber, etc.
3. Top silo dust collector, arch breaker (air disc / vibration motor)

3.Metering & Batching System (Semi-Automatic Core)

1. Electronic weighing hopper (cumulative / separate weighing)
2. Metering screw (precision feeding)
3. Pneumatic butterfly valve, manual sluice gate
4. Combination of manual weighing and automatic metering

4.Main Mixing Unit (Core Host)

1. Twin-shaft non-gravity mixer (standard design)
2. Counter-rotating twin-shaft blades
3. High-speed flying knives (fiber dispersion, anti-caking)
4. Cylinder, end cover, main shaft, seals, reducer, motor
5. Large-opening quick discharge (within 10 seconds)

5.Finished Product Buffer System

1. Finished product transition bin
2. Pneumatic discharge valve
3. Material level gauge (high/low level control)

6.Packaging & Dust Removal System

1. Valve mouth packaging machine (automatic weighing & filling)
2. Pulse bag dust collector (full-point dust removal)
3. Air compressor, pneumatic system
4. PLC control cabinet (semi-automatic control)

Working Principle

The line adopts gravity flow + batch mixing + semi-automatic metering control.Process flow: Raw material storage → Metering & batching → Forced mixing → Finished product temporary storage → Quantitative packaging.With a vertical tower layout, materials flow downward by gravity, minimizing conveying links. Manual-assisted feeding plus automatic electrical control of mixing and packaging ensure stable continuous production.

Core Performance Features

1. Compact structure, rational layout
   Vertical gravity-flow design; smooth downward flow, no re-lifting, no residue, no blockage; small footprint, high space utilization.
2. High mixing efficiency & excellent uniformity
   Equipped with twin-shaft non-gravity mixer; materials fluidize for loss-in-weight mixing; high uniformity, no segregation, short mixing time, stable batch consistency.
3. Precise metering & stable ratio
   Electronic weighing system with high accuracy and low error; automatic metering for main materials, manual assistance for additives; semi-automatic control balances precision and flexibility for multi-product production.
4. Stable operation & low failure rate
   Optimized key components; smooth transmission, reliable sealing, wear resistance; strong continuous performance, simple maintenance, few wearing parts, low long-term cost.
5. Eco-friendly & good dust control
   Fully sealed conveying + multi-point pulse dust removal; dust ports at feeding, mixing, and packaging; low workshop dust, clean environment, compliant with environmental standards.
6. Simple operation & low labor cost
   PLC centralized control, one-key start/stop, high automation; only manual feeding and bagging needed; intuitive and easy to learn, fewer workers, low labor intensity.
7. Strong adaptability & wide application
   Produces masonry, plastering, floor mortar, putty powder, tile adhesive, thermal insulation mortar, etc.; fast material change, easy formula switching.
8. Moderate investment & high cost-performance
   Between simple and fully automatic lines; low investment, quick payback, suitable output for SMEs; easily upgradable to fully automatic line.

Operating Instructions

To ensure safe and stable operation, extend service life, protect personnel safety, and guarantee product quality:

1. Operators must be professionally trained and certified. Wear PPE (safety helmet, dust mask, gloves, anti-slip shoes). No loose clothing or jewelry.
2. Before startup, inspect all parts: no jams or foreign objects; metering, dust removal, and pneumatic systems normal; electrical wiring secure; valves flexible. Do not start with faults.
3. Feed strictly according to formula. Do not alter dosages. When manually adding additives, avoid splashing or hand entanglement; close the feeding port promptly.
4. During operation, monitor equipment (speed, noise, temperature, flow). Do not leave posts. Do not open inspection doors or touch moving parts. Lock out and tag out before maintenance.
5. Do not overload the mixer. Follow mixing cycle (180–300s per batch); do not discharge early.
6. Ensure packaging scale accuracy. Bag properly to avoid leakage. Remove finished packages promptly.
7. Inspect and clean dust removal system regularly. Stop immediately if dust leaks.
8. Clean residual materials after shutdown to prevent caking and corrosion. Cut power before cleaning.
9. Protect electrical equipment from moisture, dust, and water washing. Check grounding regularly.
10. Perform scheduled maintenance: lubricate parts, inspect and replace wearing parts (blades, seals, filter bags). Record all maintenance.
11. For emergencies (jamming, overload, electrical fault), press E-stop, cut power, troubleshoot before restart.
12. No repair, maintenance, or cleaning during operation. No unauthorized modification or overloading.
