In the production process of ultrafine mill, the improvement of efficiency is a constant topic. In the actual production process, the efficiency is related to many aspects. Among them, the more important issue is the type of mill selected. A suitable ultrafine mill can better improve the production efficiency. If the selected machine itself is not suitable, it is difficult to bring good production efficiency to the production process.
The old saying goes well: ‘The workers must first sharpen their tools to achieve good results,’ meaning ‘to do a good job, first make the tools sharp, do one thing well, preparation is very important’, especially In the mine production industry, it is particularly important to choose a suitable production equipment. The problem of the type of ultrafine mill that we are talking about is mainly because it is used to produce fine powder. If the model is not reasonable, it cannot complete certain types of properties. Grinding of materials cannot be processed normally, so the selected model is very important.
In addition, when selecting ultrafine mill, we need to pay attention to its quality and personality. This can be achieved through trial operation. Then we can see how the after-sales situation provided by the manufacturer can help solve many problems in future production. Problems that help achieve better production efficiency.
One point is the selection of the production process of the ultra-fine mill. It is also noted that this machine is matched with the models of other machines in the production line so that better cooperation can be achieved and fine powder production can be completed together.
The article mainly introduces the problems associated with the selection of ultrafine mill in the production process. Choosing a suitable model can help achieve better material grinding.
The principle and structure of coal crusher is composed of a cylinder body, a cone and an air inlet pipe, an exhaust pipe etc.. Dust containing gas from inlet guide device to cut into the coal catcher, and along the inner wall of the barrel body rotate falling. This stock backspin airflow cone top most arrived, flow turning steering, discharged from the exhaust pipe.
In the air flow from the top down and from the rotation process upward, the coal under the centrifugal force, was thrown to the cylinder body and the inner wall of the cone, and fall into the hopper in the thrust and particle rotary flow itself under the action of gravity. 2, the performance of coal removal efficiency.
Generally 75% ~ 85%, and is affected by the following factors: 1) the population flow. Too large, increased wear, increased pressure loss; too small to affect the efficiency of, generally use 12 ~ 20m/s. 2) the size of structure. The cylinder and the exhaust pipe diameter decreases, properly lengthened cone, can improve the coal collection efficiency. 3) coal particle size and density. The particle size and density is bigger, the centrifugal force is bigger, the coal removal efficiency is also higher. 4) precipitator rigor. When the coal hopper is lax and leakage of air, due to the bottom of the cone is in a negative pressure state, flow will have been put into ash hopper coal back, the coal removal efficiency decrease.
In the basalt processing production line, vibration sieve plays a very important role. Lump ore after crushing machine crushing, the material particles gradually become smaller, the crushing process mainly includes: coarse crushing, crushing and fine crushing etc..
