How to Distinguish the performance of Dry Mortar Equipment？

1. Raw material measurement accuracy: dry mortar, including thermal insulation mortar, bonding mortar, etc., the formula of each mortar is not the same, but there are a variety of raw materials gathered together after mixing. 2. Mixing average: the main machine of the dry mortar equipment is a dual-axis blade non-gravity mixer, which makes the material project in the three-dimensional direction and converge with each other. The high-speed flying knife will break up the clumping material, and the materials of different particle size and density will be mixed and average in a very short time, and the mixer will not produce segregation. 3. The effect of dust removal: the powder particles after the dust removal of the blender can complete zero emission and recycling applications, and the emission requirements of the dust regulations reach or are higher than the excessive environmental protection grade regulations. 4. Reasonable structure: dry mortar equipment in the raw material tank, weighing system, reporting equipment, mixing host, packaging equipment, dust removal equipment, etc., due to the large number of equipment varieties, should be in the limited occupation area and space to stop reasonable arrangement, save equipment resources and site resources. 5. Continuous work and no fault:...

Is the Sand Dryer the Higher the Temperature, the Greater the Yield?

As we all know, the river sand dryer is to achieve dehydration and drying through the contact of high humidity river sand and high temperature flue gas in the drum and heat exchange. Therefore, temperature is one of the important factors in the drying process of river sand. However, some users in the process of drying river sand, often increase the temperature in the drying cylinder, thinking that this can increase the output of the river sand dryer. So, the higher the temperature of the river sand dryer, the greater his output? 1. First of all, there are many factors affecting the output of river sand dryer, and the temperature in the drying cylinder is only one of the reasons affecting the drying efficiency and quality of river sand. It is undeniable that in the operation of drying river sand, if the temperature in the drying cylinder is too low, it will cause the phenomenon of incomplete or uneven drying of river sand, and then reduce the yield and quality of river sand drying. However, if the temperature is too high, it is easy to form a paste phenomenon. 2. Secondly, when the river sand is drying, the main function...

How to choose Sand Dryer Equipment?

Sand is a common granular material, which is used in construction, road construction, filtration, culture and beautification, and when smelting fast solvents exist in many aspects of social life. We can see the figure of sand everywhere in our daily life, it has become an indispensable part of our daily life, sand in the application process many times need to be processed to be used, sand dryer in this link plays an important role, the current market production of dryer manufacturers more, For those who do not buy experience, they do not know how to buy the right sand dryer for them. Today, we will explain how to buy sand dryer equipment for you. 1. Choose the right type of sand dryer： At present, there are many manufacturers producing dryers on the market, and there are more types of dryers. Common types of dryers include tumble dryers, long drum sand dryers, tower dryers, three-return sand and other drying equipment. Due to the relatively stable chemical nature of sand, water often only exists on the surface of the material, and the water content is not large. All the general choice of tumble dryer to dry, the sand in the lifting plate...
