Ultrafine mill compared to the traditional mill difference and progress
SBM Shanghai Machinery Co., Ltd. is a professional manufacturer of milling equipment manufacturers, the production of the mill step by step the development and growth, from the initial Raymond mill to the current Ultrafine mill, ultrafine grinding, step by step Leap shows SBM Machinery Co., Ltd. progressing again and again, the following SBM for everyone to talk about the difference between ultrafine mill equipment and ordinary traditional mill and progress, why choose the ultrafine mill equipment.
We look at ultra-fine grinding, the mill's name is relative to Raymond mill terms. That is, after the modified design of the new mill, its fineness compared to ordinary Raymond mill fineness increased a lot, the mill on the basis of the traditional mill technology improvements, with high efficiency and energy saving new mill Equipment, R line pendulum mill replacement products. Then it ordinary grinding equipment in those areas to improve it, the following brief introduction.
The new generation of ultra-fine grinding can be applied to the following six ore milling processing, humidity below 6 percent. Fineness between 30-3000 mesh directly adjusted. New grinding system equipment and high-tech grading equipment so that the new ultra-fine grinding quickly in the market has been the promotion and application, and access to the user friends alike.
Yesterday, the company manager of professional milling machine mill test machine in my site to explain the system of knowledge. Mainly to us to explain the work process and principle of Raymond mill, but also introduces the milling equipment in the work process often encounter some problems, I am here to describe a specific reference for users and friends.
The working process of the mill: firstly, the material is fed to the mill by the feeder, and then the grinding process of the material between the mill and the grinding ring is carried out under the action of the internal grinding device; the qualified material passes through the lower air duct The wind flows up, through the analysis of qualified sorting through here to grinding 400 items for the standard material that is 400 and above pass, the following down to the ultrafine mill for grinding again, the lower part of the material for the blade Shovel to the grinding roller and milling between the milling, in order to achieve adequate grinding of materials. After passing through the analysis of qualified materials from the pipeline into the collector, according to the needs of the collector was collected properly, unsuitable dust is collected to the precipitator. This new ultra-fine grinding device with negative pressure system, what is negative pressure, simply that is below atmospheric pressure, that is, the pressure inside the mill is less than the external pressure, some users will worry about the mill inlet part of the site will not There will be material powder out, this is generally not the case. Unless the mill closed the whole system is not closely led to ultra-fine grinding negative pressure into a positive pressure system, there will be dusting phenomenon. So users in the process of application must check the mill is closed.
