Dry mortar plant, also known as dry mortar production line, dry mixer mortar plant, is a set of automatic production equipment specifically designed for the construction, building materials and other industries to produce various dry powder mortar building materials. It can fully and evenly mix dry aggregates or powders, cement, various sands, additives and other raw materials to make dry powder like substances, and store them in bags.
When used on site, simply adding water according to the specified ratio, it can be directly used as building materials.
The dry mortar plant is widely used for material mixing operations in mining, building materials, chemical and other fields, especially in the construction industry for the mixing production of putty powder, tile adhesive, gypsum mortar, dry mortar and other materials. There are various types of finished products that can be used as different bonding materials for various building bonding occasions, such as masonry mortar, plastering mortar, floor mortar, tile bonding mortar, jointing mortar, insulation mortar, waterproof mortar, decorative mortar, colored mortar, self leveling mortar, etc.
Composition Of Dry Mortar Plant
The dry mortar equipment is mainly divided into 8 parts.
- Drying system: Fully dry the raw materials to be mixed
- Raw material hoisting system: Elevate raw materials into the storage system
- Storage system: Separately store various raw materials, additives, etc
- Hybrid system: the core equipment of the production line, a place where various raw materials are fully mixed
- Packaging system: measure and package the finished dry mortar
- Dust removal system: Processes the dust generated by the production line to ensure a clean production environment
- Control system: Controls the operation and processes of the entire production line
Classification of Dry Powder Plant
Common dry mortar plant can be divided into four categories.
Simple Dry Mortar Plant
Simple dry mortar plant (1-6t/h), semi-automatic, manual feeding, no drying, no weighing, no silo, with packaging machine
Small tower dry mortar plant (≤10t/h), semi-automatic or fully automatic, no drying, can be equipped with silos, weighing, and packaging machine.
The simple dry mortar production line uses a two-layer frame structure, equipped with a dual axis gravity free mixer, finished product warehouse, packaging machine, and pulse dust collector. The equipment covers an area of about 20m3 and has a height of 6.5m. The production line has an annual output of 3-5 tons, which is suitable for customers with limited plant height and initial investment.
Medium Dry Mortar Plant
Medium-sized Mortar Plant (10-20t/h), fully automatic, with or without drying, with silos, weighing, and packaging machines.
The medium-sized dry mortar plant uses a three-layer frame structure consisting of a mixing bin, a dual axis gravity free mixer, a finished product bin, and a packaging machine. It is equipped with a pulse dust collector and occupies an area of about 30m3 with a height of 8.5m. The investment of this production line is moderate and the effect is fast. It can be upgraded to a fully automatic dry mortar plant in the future.
Large Dry Mortar Plant
Large Dry Mortar Plant (30-40t/h), fully automatic, with or without drying, weighing, packaging or bulk
- High cost investment
- High degree of automation
- Long capital recovery cycle
- Basically, they all come with bulk systems
Working Principle of Dry Mortar Plant
The main working principle of the dry mortar plant is very simple. In summary, it is to mix and stir dry aggregates, sand materials, powders, additives and other raw materials in a certain proportion to produce dry powder products, which can be bagged or directly transported by vehicles to construction sites for use. The specific steps are roughly as follows.
- The raw materials enter the production line through the feeding port, with a large proportion of raw materials such as cement entering the pre-mixing bin through the elevator, and a small proportion of valuable raw materials such as cellulose and rubber powder being weighed by an electronic scale and put into the additive hopper.
- After the raw materials are preliminarily mixed in the pre mixing bin, they enter the mixer for further mixing. A pair of relatively rotating main shafts inside the mixer drive the blades to rotate, throwing the material towards the spatial layer at a certain angle. The particles experience instantaneous weight loss in the spatial flow layer, and centrifugal force and gravity cancel each other out, mixing into each other’s areas and forming a fluidized weight loss zone in the middle layer, quickly achieving the goal of uniform mixing.
- The mixed finished products are quickly placed in the finished product storage bin for buffering and storage through pneumatic quick opening doors. The dry mortar in the finished product silo is fed into the packaging machine through a flexible connection for measurement and packaging.
Advantages Of Dry Mortar Plant From LUTON GROUP
- The GH series dual axis blade gravity free mixer adopts a blade structure internally, which provides better mixing effect, shorter mixing time of 3-5 minutes per batch, and lower unit energy consumption ( 60% lower than ordinary horizontal screw belt mixer).
- Plowing blade mixer has fast mixing speed, and the material mixing time is compressed to 90-180 seconds. With high mixing accuracy and good uniformity, this kind of mixer can meet construction requirements greatly. There is no dead zone, residue, or leakage during unloading, and the unloading time is short. The mixing blades are designed with high-quality stainless steel wear-resistant plates, which have extremely high wear resistance and effectively extend the service life of the mixer.
- The three-return dryer is composed of three concentric cylinders of different diameters, which are embedded and combined with each other in a certain relationship and structural form. The heat dissipation area and thermal energy loss of the cylinder are significantly reduced. This effectively improves the utilization efficiency of thermal energy and reduces energy consumption. This dryer is mainly used for drying river sand, yellow sand, quartz sand, machine-made sand, various specifications of molding sand, slag, clay, etc.
- The DMC pulse bag filter is an efficient bag filter that our company has successfully demonstrated through repeated testing and absorbing advanced technologies from both domestic and foreign sources. The design is compact in structure, easy to maintain, and has the characteristics of high efficiency in dust cleaning. It widely used for purifying dusty gases in industries such as building materials, mining, chemical, cool and powder processing. It is an ideal choice for environmental dust removal.
- GH series new valve port packaging machine is suitable for automatic quantitative packaging of powder or granular objects. This series of packaging machines is designed with advanced technology. The mechanical and electrical units are controlled through new designs and automatic instruments, making them efficient, stable and easy to operate. Through rational and scientific design, it has low wear, long service life, and high packaging accuracy. Additionally, automatic bagging, ultrasonic sealing and automatic bagging function can be added as needed. It can be widely used in industries such as building materials, chemicals and minerals.
- The automatic batching system can freely be set different material batching sequences according to needs. The measuring warehouse can be added automatic pre vibration function as needed to minimize the residual discharge and achieve high measurement accuracy. Small material batching can be controlled by a precision frequency converter for precise feeding.
