1. Product Introduction
The dry mortar production line is a complete integrated industrial
production system specially designed for mass manufacturing of
dry-mixed and pre-mixed construction mortars. It adopts a modular
and automated production process covering raw material storage,
precise batching, conveying, homogeneous mixing, finished material
storage and automatic packaging. Equipped with a core twin-shaft
paddle mixer, the system realizes accurate proportioning and full
uniform mixing of sand, cement, fly ash, mineral powder and various
functional additives. The whole production process adopts closed
operation with intelligent PLC control, effectively solving the
problems of traditional manual mixing such as unstable proportion,
uneven mixing, low efficiency and serious dust pollution. This
full-process automatic production line can stably produce various
ordinary and special mortars, and is widely applicable to medium
and large-scale standardized production of building mortar in
construction materials factories.

4. Operation Precautions
Pre-operation Inspection: Check the tightness of all connecting bolts, the integrity of
mixing paddles and sealing parts, the normal oil level of reducer
and the flexibility of conveying equipment before startup. Confirm
no foreign matters in the mixing cylinder and production pipeline,
and prohibit faulty startup.
Standard Feeding Management: Strictly operate according to the set production formula and
prohibit random adjustment of material ratio. It is forbidden to
feed oversize stones, metal sundries and other hard impurities to
avoid damaging mixing host and conveying equipment. Micro-powder
additives shall be fed evenly in batches to prevent agglomeration.
Operation Process Supervision: It is forbidden to open the maintenance door or touch operating
equipment during production. The equipment is not allowed to run
under overload for a long time. Once abnormal noise, severe
vibration, powder leakage and overheating are found, stop the
machine and cut off power immediately for troubleshooting.
Post-production Cleaning: Clean residual mortar and powder inside the mixing host, silo and
pipeline thoroughly after each production shift to prevent material
solidification and caking, which may affect subsequent mixing
quality and equipment service life.
Regular Maintenance & Inspection: Regularly replace reducer lubricating oil and worn vulnerable
parts such as paddles, liners and sealing strips. Check the
sensitivity of batching sensors and dust removal equipment
regularly to ensure stable operation of the whole line.
Safety & Electrical Specification: The equipment shall be grounded reliably. The electrical control
cabinet and lines shall be kept dry and dust-proof.
Non-professional personnel are prohibited from disassembling
electrical and transmission components without permission. Cut off
the total power supply during equipment maintenance.
Environmental & Site Requirements: The production line shall be installed on flat and hardened
foundation with stable fixing. Keep the dust removal system running
normally during operation to ensure clean and ventilated production
environment and meet environmental protection standards.

6. FAQ
Q1: What kinds of mortar can the dry mortar production line
produce?
A: This production line supports the production of almost all
dry-mixed mortars, including ordinary masonry and plastering
mortar, as well as special mortars such as waterproof, thermal
insulation, anti-crack, self-leveling, tile adhesive and putty
powder. It can realize multi-formula switching production to meet
diversified market demands.
Q2: Why is the mixing uniformity of finished mortar unstable?
A: The main causes include inaccurate batching parameters,
insufficient single-batch mixing time, serious wear of mixing
paddles, residual caking materials in the cylinder and uneven
feeding of additives. Solutions: calibrate the batching system
regularly, adjust the mixing cycle, replace worn parts in time, and
clean the equipment thoroughly after each use.
Q3: How to solve dust leakage during production?
A: Dust leakage is mainly caused by aging sealing strips, blocked
dust removal equipment or untight closing of maintenance doors and
feeding ports. It can be solved by replacing damaged sealing parts
regularly, cleaning the dust removal filter cartridge timely and
checking the tightness of each connecting port before startup.
Q4: Is the production line easy to operate and maintain?
A: The whole line adopts intelligent PLC one-key control with

A: Yes. We provide full personalized customization services. The
production line capacity (1-30t/h), equipment configuration, layout
mode and supporting systems can be adjusted according to customers’
site space, product types and production scale to meet different
production demands.
Q6: What are the advantages compared with traditional manual mixing
and single mixer?
A: The integrated automatic production line realizes unified
batching, mixing and packaging, with higher production efficiency
and more stable product quality. It solves the problems of low
precision, serious dust pollution, high labor cost and unstable
batch quality of traditional single equipment, and is more suitable
