Working principle of automatic batching dry mortar mix plant
Dry powder mortar is also called dry-mixed mortar (pre-mixed mortar). It is a finished dry-mixed mortar produced by a factory-based method with accurate ingredients and uniform mixing. It can be used by adding water and stirring in the construction site. The production and application of dry-mixed mortar is a new technological revolution in the construction and building materials industry, and it is a major direction for future material development.
Production process of automatic dry mortar batch mixing plant
There are different slolutions for dry-mix mortar production according to requirements and different markets. Commonly used is the tower layout, which lifts all the pre-processed raw materials into the raw material silo. The raw materials flow out of the silo by their own gravity, and then packaged into bags, or packed in bulk tanker, or pack in end product silo through computer batching&weighing, screw conveying and mixing to become the final product. All production is operated by a computer control system. The batching accuracy is high, the use is flexible, the closed production system makes the working site clean and free of dust pollution, ensures workers healthy, modular equipment structure is easy to expand, so that production capacity can be connected with market development. Choosing a complete set of mortar production equipment with superior performance must focus on the following aspects.
Performance characteristics
Traditional mortar is mixed and used on the construction site which requires a certain space, dust will also cause environmental pollution on the site. At the same time, the materials are stacked on the ground in the open state resulting in more impurities, large mud content, inaccurate batching measurement. Workability is difficult to control, and the sieving of aggregates is random, resulting in high porosity of the mortar, large shrinkage rate, poor impermeability, and ultimately leading to hollowing, cracks and penetration in the plastering of external walls. In contrast, all ingredients of dry-mixed mortar are accurately metered in the production workshop and thoroughly mixed evenly, and then mixed with water according to the determined mortar ratio at the construction site, it overcame many problems such as inaccurate metering of ingredients, environmental pollution, and excessive soil content. At the same time, product performance can be improved and optimized by adding different chemical additives such as: Plasticizer, setting agent, consistency, solubility, foaming, lubricity, strength, corrosion resistance, colorfastness, sealing, cracking and impermeability, etc., which can basically meet the requirements of new wall materials.
Composition of automatic dry mortar batch mixing plant
Automatic dry mortar batch mixing plant equipment is mainly composed of cement SILOS; fly ash SILOS; Sands silos: kinds of other materials silo(optional according to cusomter actual demand); large and small batching scales; screw conveyors; bucket elevators; double-shaft paddle zero-gravity (coulter) mixers; pre-mixing hopper; finished products silo; automatic packaging machines; dust removal systems (pulse Type dust collector); air balance system; control system (button ,touch screen type, PLC industrial control type); bulk storage bin; sand drying system.
According to the production process, the raw materials can be sent to the batching scale by the screw conveyor for the different formulas of different dry powder mortars for measurement. After mixing, they enter the finished product silo, partial end product is bagged by the automatic packaging machine, partial is passed through the elevator transported to bulk storage silo or load into bulk tanker and sent to the construction site. Directly add the wate while mixing and use. It can be divided into ladder type and tower type automatic dry mortar batch mixing plant.
There are different solutions for dry-mix mortar production according to requirements and different markets. The most commonly used is a tower-style process layout, which lifts all pre-processed raw materials to raw material silo. The raw materials flow out of the silo by their own gravity, and are then packaged into bags or packed in bulk tanker or store in end product silo through computer batching, screw conveyor measurement, mixing to make it become the final product. All production is operated by the computer control system.
Sand drying machine of automatic batching dry mortar mix plant
Sand dryer machines are widely used in dry-mixed mortar, yellow sand, cement plant slag, clay, coal, iron fen, building materials, chemicals, casting and other industries.
Dryer features:
The final moisture content of the finished sand is less than 0.5%, which is the first choice for the dry-mixed mortar and powder production line.
The self-insulation thermal efficiency of the dryer tank is as high as 80% (the thermal protection efficiency of the traditional single cylinder drum is only 35%), and the thermal efficiency is increased by 45%.
The fuel can be coal, desiel or gas, and can supply blocks, pellets,
Compared with the single drum dryer, it can reduce the floor space by about 50%, the civil construction investment by 50%, and the energy consumption by 60%
Made of alloy steel plate, it is 4 times more wear-resistant than ordinary steel.
It can easily adjust the required moisture index according to user needs.
The outlet temperature is low; the dust removal equipment can be used for a long time.
No need to rotate large and small gears, use supporting wheels for rotating
Dry sand classification and screening machine-automatic batching dry mortar mix plant
The projection type vibrating screen with reliable quality and low investment is preferred. Compared with the traditional horizontal screen, it has the following advantages: low investment; small size; reliable, even in the case of overload, the screen will not be torn due to the inclined setting ;
