Ball mill is widely used in the grinding operation of electric power, chemical industry, mineral processing, cement industry, especially in the mineral processing industry. At present, there are various kinds of ball mill types on the market with different functions and prices. It is difficult to select a suitable ball mail machine when choosing it. Next, Xinhai  ball mill machine manufacturers  take you to learn about the ball mill and then select the suitable  ball mill types  for your mineral processing plant. One. Learn about the ball mill types According to the shape of the grinding medium, the ball mill can be divided into ball mill,  rod mill , rod-ball mill, gravel mill. According to the unloading way, the ball mill can be divided into tail unloading ball mill, middle unloading ball mill. According to the transmission mode, the ball mill can be divided into center drive ball mill, edge drive ball mill. According to different process operations...

The working principle refers to the basic law of its work, mostly refers to the operation of things or the basic law of the operation. So what’s the  working principle of ball mill machine ? Next，Xinhai  ball mill manufacturers  will introduce the running state of the ball mill machine from the structure of the ball mill machine, motion state of ball mill machine and the working principle of the ball mill machine. 1. The main composition of the ball mill machine The basic composition of the  ball mill machine  includes a cylindrical barrel, end cover, bearing and transmission ring, etc. The barrel is mounted on a large bearing and placed horizontally. The cylinder body is equipped with the unquantified steel ball or steel rod (25mm-150mm of large steel ball), which accounts for 25%-50% of the effective volume of the whole cylinder body. 2. Motion state of ball mill machine In the grinding process of the ball mill machine, the rotation speed of t...

The rock gold in the mountain is separated from the quartz vein caused by water erosion. Most of this kind of gold is fine as the sand, so it is called alluvial gold. but what are the alluvial gold mining processes? And what is  alluvial gold equipment  commonly used in the alluvial gold washing plant? Due to the free state of gold in sand gold deposits, and the specific gravity difference between gold and sand is very obvious, the gravity separation method is an ideal and efficient method to extract gold from the sand. The principle of the alluvial gold mining process is to recover gold and all kinds of associated heavy minerals from raw ore as much as possible by the gravity dressing method. The lower limit of the particle size of gold recovery by gravity separation method is generally 0.01mm. In the practice, the alluvial gold mining process generally includes breaking, screening and gravity separation. One. Breaking and screening Many gold ore deposits contain c...

Flotation cell is the core equipment of the whole flotation workshop. After adding agent, the ore particles adhere to the bubbles through the agitation and inflation. The bubbles float to the pulp surface, and scraped by the scraper blade into foams. In flotation process, the factors influencing flotation effect include grinding fineness, slurry and feeding concentration, air inflation, flotation time. In this passage, we will analyze the above factors, and find out how they influence flotation effects of flotation cell. One. The influence of grinding fineness The grinding fineness is an adjustable factor, which is realized through crushing and grinding operation. The suitable grinding particle size is determined by the inlay size of the valuable mineral through mineral processing experiment. The valuable minerals should be separated with the gangue minerals basically, and reducing the ore spawn of valuable minerals and gangue minerals. For coarse single minerals, the grinding f...
