The equipment of the dry powder mortar production line mainly consists of a hoist, a pre mixing bin, a small bin, a mixer, a finished product bin, a packaging machine, a dust collector, an electrical control cabinet, and a gas phase balance system. Adopting a dual axis blade high-efficiency mixer, the original state of the material is not destroyed, ensuring that the insulation coefficient of the mortar will not decrease due to the shape damage of the insulation material, and ensuring the insulation effect of the product.

Components of equipment for dry powder mortar production line

The dry powder mortar equipment mainly consists of a storage tank, a dual axis gravity free mixer, a hoist, a mixing bin, a small material bin, a finished product bin, a packaging scale, a bucket elevator, a dust collector, a fully automatic metering and batching scale bin, and a frame. The storage tank is mainly used to store raw materials, with a general capacity of 60 cubic meters and a quantity of 3. It is used to store cement, fly ash, sand and other materials. During production, cement, fly ash, sand and other materials are proportionally transported to the batching scale warehouse according to the customer’s formula. The prepared materials are then sent to the bucket elevator by the batching scale warehouse. Small proportion precious mother materials such as cellulose and rubber powder can be measured and fed into the additive hopper through an electronic scale. The materials are lifted to the mixing bin on the frame by the bucket elevator and wait for mixing. Then the materials are discharged into the dual axis gravity free mixer for mixing. The mixed materials enter the finished product warehouse through a pneumatic door and are packaged by a valve packaging machine to complete the operation. Compared with simple production lines, Another step forward.

Dry powder mortar is mainly composed of raw materials such as cement, dry sand, fly ash, and thickening powder. Special process mortar also needs to add a small amount of additives such as cellulose ether. These powder particles are stored in storage tanks for production use. Wet sand is first transported by a conveyor to the screening machine for screening, and then sent by a conveyor belt to the three return dryer in the drying main line for drying treatment.

1. Accurate metering and batching system
   There are many ways to measure ingredients, among which the screw conveyor has the best performance because it is suitable for all powder materials in mortar. It adopts frequency conversion control, wear-resistant materials, horizontal arrangement, high accuracy, and long service life Additives (small materials) are measured in trace amounts The requirement for measurement is crucial when the ratio is between one thousand and ten thousand
2. Efficient hybrid system
   The mixer is the most critical part of mortar material production and also the “heart” of the entire production line The “Tongding” brand mixer is a weighted and efficient mixer that combines foreign technology for dry mixed mortar services. It can achieve the following performance
   (1) The mixing uniformity is above 99%, and it takes about 1-3 minutes to mix evenly.
   (2) With unique stirring principles and mixer design, it achieves mixing quality and high efficiency while reducing energy consumption. (Mixing principle of organic rubber powder polystyrene particle insulation mortar and inorganic vitrified microsphere insulation mortar)
   (3) High speed flying knife efficiently disperses fibers.
   (4) The whole machine adopts gas seal, pneumatic large opening door, unique discharge device door, and wear-resistant design of blade plate, with long service life, easy maintenance, reliability and stability.
3. Finished product warehouse and secondary mixing system
   The finished product warehouse and secondary mixing eliminate the problems of excessive fibers, poor flowability, and easy bridging and adhesion of granular materials. The system achieves fast and continuous discharge, and can smoothly discharge special raw materials and finished products from the warehouse by adding an air flotation device.
4. Environmentally friendly and precise packaging systems and bulk technology
   According to the product variety, the company provides valve pockets, open pockets, and packaging machines. The packaging range is 20-50kg, meeting different project requirements. Through the control system, the operator only needs to insert the packaging bag into the valve port, and other tasks can be automatically completed. The packaged products are transported by a belt conveyor to the palletizing platform for storage, and the forklift completes the product storage work. Accurate weighing and high packaging quality.
5. Intelligent computer batching system
   Computer intelligent control system LCPLC. The system has self checking accuracy, software calibration and maintenance convenience, color CRT display of section equipment process flow chart, dual warehouse simultaneous feeding to shorten ingredient time, formula management, printing of real-time ingredient reports, formula output, raw material consumption reports, and quantitative management reports such as shift day, star period, ten day, and month statistics.
6. Complete configuration of dry powder mortar equipment:
   Large capacity dry powder mortar equipment generally requires 4-6 raw material tanks, of which two large tanks are used to store bulk cement and fly ash, and the remaining small tanks are used to store light calcium, heavy calcium, sand, small materials, etc. Bulk cement and fly ash entering the tank do not require lifting equipment and rely on pump trucks for injection. Bulk fly ash silos are generally cylindrical support structures, with dust removal equipment on the upper part to prevent dust leakage, and arch breaking devices on the lower part to prevent powder agglomeration and ensure smooth discharge. They are also equipped with level sensing devices to monitor the usage of materials in the silo at any time.

When using dry powder mortar production line equipment, five key details need to be noted to ensure the smooth operation of the equipment. These details include:

1. Operators should conduct regular equipment inspections and maintenance. If any abnormalities or deviations from normal operation are found, the power should be immediately turned off and a comprehensive inspection and repair should be carried out.

2. The mixing degree of dry powder mortar production line equipment can be divided into three types: ideal mixing, random mixing, and incomplete mixing.

3. In the event of a sudden power outage, the materials in the mixer should be discharged first before starting the equipment.
4. The mixing degree of materials in the dry powder mortar production line equipment depends on factors such as the proportion, physical state, and characteristics of the materials to be mixed, as well as the type of mixing machinery used and the mixing operation time.
5. If the flowability of materials in the mixer is poor and particles or powdery solids adhere to each other, it is recommended to use a mixing machine with mechanical flipping, pressing, and rolling actions.

These details, although often overlooked, are crucial for the normal operation of the equipment.
