The working part of the cone crusher is two truncated cones, one is a fixed cone (also called an outer cone) and the other is a moving cone (also called an inner cone). In the portion of the moving cone close to the fixed cone, the material is pressed, impacted and bent by the moving cone to become the crushing cavity; when the moving cone is offset from the fixed cone, the broken material is discharged under the self-weight at the bottom of the cone , becomes the discharge port, and the…

From the physical phenomena and geometrical characteristics of ore crushing and ball mill grinding process, grinding is the continuation of crushing ore, which is a process of reducing the size of a nugget or ore. However, from the thermodynamic point of view, grinding is a process of internal energy increase. The grinding machine works on the ore block and overcomes the cohesion of the ore block to break it. Therefore,…

Precision casting refers to a general term for a process. It refers to the process of obtaining precise castings by using precise molding methods. Many castings can be obtained by precision casting, such as: hardware parts, auto parts, locomotive parts and various valves. Etc. So it is a very important process in the industry today. So when we are doing precision casting, we need to pay attention to what factors may affect the precision of precision…

1. Does precision casting have to be manufactured by precision casting? Can it be used to produce thin-walled castings?

The manufacturing process of precision castings is precision casting, which is without a doubt. However, this process can also be used for the production of thin-walled castings, in which the outer casing of the mold needs to be preheated at a high temperature, and the solidification speed of the metal during the casting process…

There are two main types of dewaxing casting methods: the Solid Mold method and the Ceramic Shell Mold method, the latter being the former method of improvement.

The shell mold method until the wax type is produced in the same way as the solid mold, but after one damp and sand (or floating sand), the mold-free operation is not carried out, but the dipping and sanding are repeated several times. Until the predetermined shell thickness is obtained. Drying, heating, melting and waxing,…

Raymond mill is one of the common equipments in mining machinery. What kind of equipment can not withstand long-term damage, there will always be some faults in long-term use, and don't be afraid of problems. Finding a solution is the key. Next, SBM Heavy Industry's professional technicians will explain the problem of excessive temperature of Raymond mill.

Improper use of Raymond mill equipment, there will be a…

VSI sand making machine is a kind of widely used mechanical equipment, which plays an important role in the sand making, crushing and rough grinding industries, but the most used one is the sand making industry. Since the companies that produce the equipment are mostly mining machinery manufacturers, there are certain requirements for sand and gravel.

1. The particle requirements for the broken…

With the development of the times, there are many manufacturers of sand making machine in China, but it does not mean that the sand making machines produced by each manufacturer are the same, so customers need to carefully select the sand making machine manufacturers when purchasing sand making machines. . What is the most important thing in the production of sand making machines? The following SBM…

Gear drive failure is one of the more common faults during the operation of the Raymond mill. Once the Raymond gear transmission fails, it will seriously affect the smooth operation of the milling operation and delay the effective operation of the entire milling line. then. What is the cause of the failure of Raymond gear transmission?

1. Due to the special working environment of Raymond Milling, the working…

The casting process of Raymond Mill equipment is an important factor to determine the quality of wear-resisting parts. Today, Shanghai SBM Heavy Industry Co., Ltd. Introduces three factors that affect the casting process of Raymond mill.

1. The quality of raw materials used in casting directly determines the quality of Raymond mill. For example, the quality of refractory materials, fuel, flux and casting sand is…

Sand and gravel aggregate is an indispensable important material in the construction of various infrastructures. In recent years, the development of urbanization is in full swing, the demand for sand and gravel is increasing day by day, and the single river sand mining can no longer meet the needs of construction projects, and for a long time no Moderate mining, the river is overwhelmed, causing soil erosion, riverbed subsidence, the ecological environment is worsening, and China's river…
