Selection of the premixed mortar production line

1 The structure form of the production line determines the choice of
the structure form of the ready-mixed mortar production line, and it is generally believed that the investment of the tower type is large, the duration of the stage is short, and the investment is small. And for the current domestic widely used phased or horizontal production lines, from the actual investment, tower equipment because of its advanced technology, the total cost is not high, with the stage or horizontal production line is basically the same, or even lower.
m-tec production line uses a tower structure to
chinese
. The ordinary tower structure is characterized by compactness, low production costs, adaptation to various forms of raw materials, raw materials to avoid cross-contamination. The production line designed and built by m-tec (see Figure 1) has more advanced and reasonable connotations that cannot be replicated and imitated.
the m-tec tower structure production line2 Capacity determination
according to domestic market demand, m-tec provides MTA1000, MTA2000, MTA3000 type 3 production lines, production capacity of 25, 45, 65 t/h.3 Raw material storage
to build a production line that can store more raw materials, it is necessary to understand the specific supply and quality of raw materials.
m-tec production line with 8 to 14 main material storage warehouses, each 30 to 80 m3. Among them, sand silos can be set 4 to 6 according to different materials, and additive storage can be set 4 to 8.4 Sand treatment
at present, river sand drying treatment is being used as a common technical solution, but the mechanism sand is more and more widely used in the production of ready-mixed mortar. Depending on the raw material resources, m-tec recommends the configuration of mechanism sand equipment. It should be noted that although the overall cost of mechanism sand equipment is low, there are two major problems that need special attention to the large installed capacity and dust treatment. In addition, sand screening and grade matching are also critical.5 Ingredient Metering Weighing System
The accuracy, reliability and stability of the metering system greatly affect the cost control of raw materials, no matter how to pursue the accuracy of raw material metering can not be overdrive. The m-tec dosing weighing system is shown in Figure 2.
m-tec weighing system, the measurement of main materials and additives consists of a metering spiral and a high-precision weighing system with special ultra-wear-resistant materials. Metering spirals are controlled by variable frequency, chemical additives are also controlled by high-precision metering spiral ingredients, original weighing systems imported from m-tec, high precision, high reliability, material costs and product quality are fundamentally controlled.core equipment of the
6 hybrid selection production line is the mixer, which must first consider the advanced mixing principle and high mixing performance. At present, many investors, even equipment suppliers, simply equate mortar with concrete, mortar equipment with concrete equipment, and if the mixer is chosen according to this line of thinking, it is basically equivalent to high energy consumption, high cost, low quality production of mortar.
6.1 m-tec high-performance mixer features
(1) hybrid performance. The mixer has a wide range of applicability, can mix different ratios and composition of materials, and achieve the top indicators of the average variance. There is a general misconception about mixed performance that the longer the mixing time, the higher the uniformity, and the fact is the opposite, the increase and hold of uniformity is only related to the technical content of the mixer, there is no linear relationship with the mixing time, but after a certain period of time there is a downward trend———
(2) productivity. The efficiency of the mixer mainly refers to the mixing time and discharge time of the mixer. In general, a mixing time of 60 to 120 s is an ideal mixer, while a discharge time of 10 to 30 s is acceptable. The effective volume of the mixer is also critical, to achieve the same yield, the smaller the volume of the mixer, the better, the higher the volume ratio of the material, the better, a good mixer volume ratio can be as high as 75%, the difference is only 20%.
(3) production capacity. In the case of equal mixer volume, higher hourly production reflects the advantages of hybrid technology, ensuring that the design capacity of the production line can be guaranteed in the production of any product or product portfolio, and that the production line can work efficiently during peak production season or when the market is in urgent need.
(4) to match the system, can play the efficiency of the metering system and the efficiency of the mixer itself.
(5) control the cost of raw materials.
(6) consumes low power.
6.2 m-tec mixer economic benefits
According to the data we analyzed earlier, in the mixer this link, for the control and reduction of material costs, often completely unexpected investors, high-performance mixers can allow investors to recover their investment in six months time, and long-term material costs to the lowest level. 7 m-tec computer control system
for the special nature of dry powder mortar production, m-tec independent research and development of computer intelligent control system, the hardware basically adopts the world's leading brand products, with visual operating interface, powerful, flexible operation, stable operation characteristics.
