Mixer is a kind of construction machinery, which is mainly used to mix cement, sand, all kinds of dry powder mortar and other building materials. This is a machine with a shaft with blades rotating in a cylinder or tank to stir and mix a variety of raw materials into a mixture or suitable consistency. There are many kinds of mixers, including forced mixer, single horizontal shaft mixer, double horizontal shaft mixer and so on.
working principle
The mixer is determined by multiple parameters. It is impossible to describe a mixer with any single parameter. Shaft power (P), blade discharge (q), head (H), blade diameter (d) and mixing speed (n) are five basic parameters to describe a mixer. The discharge volume of the blade is directly proportional to the flow standard of the blade itself, the first power of the blade speed and the third power of the blade diameter. The shaft power consumed by mixing is directly proportional to the specific gravity of the fluid, the power standard of the blade itself, the third power of the rotating speed and the fifth power of the blade diameter. Under the condition of certain power and blade form, the discharge volume (q) and pressure head (H) of the blade can be adjusted by changing the matching of the diameter (d) and speed (n) of the blade, that is, the large-diameter blade with a mixer with low speed (ensuring constant shaft power) will produce higher flow effect and lower pressure head, while the small-diameter blade with high speed will produce higher pressure head and lower flow effect. In the stirred tank, the only way to make the micro clusters collide with each other is to provide sufficient shear rate. From the mixing mechanism, it is the existence of fluid velocity difference that makes the fluid layers mix with each other.

The hammer head of the crusher is an essential accessory for the coal mine crusher. At present, the common crusher hammer head on the market is generally divided into two kinds, forging hammer head and casting hammer head. The hammer head of forging crusher is mainly used to heat the blank and apply pressure on the blank by forging machine to produce plastic deformation of the blank, so as to obtain the hammer head of the crusher with the given shape, size and mechanical properties. The casting loose defect caused by casting hammers can be greatly changed by forging and the structure of hammers can be optimized. Therefore, the forging hammer head performance is superior to the casting hammer head, relatively also more wear-resisting. In order to guarantee the wear resistance of forging hammer head, it is necessary to choose the material with better wear resistance. At present, the common materials in the market include high manganese steel, high chromium cast iron, low carbon alloy steel, etc., which can be selected according to the use conditions of different mining areas. Coal machine parts manufacturer Henan Shuanzhi production of various types of forging hammer head, crushing shaft group. More coal accessories small knowledge, welcome you to continue to pay attention to Henan Shuangzhi.
