Stone stone crusher is a kind of mechanical equipment for crushing and processing stone sand production process, common stone crushing equipment include jaw crusher, impact crusher, hammer crusher, cone crusher and so on, there is a big difference between the performance of different stone crushing machine, mainly to remind the user to bearing stone crusher, bearing stone crushing machine is a weak point.

It’s a professional stone crushing equipment manufacturer. Here I would like to talk about the situation of the bearing temperature rising due to the chance of stone breaking, and what are the causes of this situation and how to deal with this situation. Here is a brief talk to you. The reason that the rotor bearing temperature of the stone crusher is too high may be in the following aspects.

The bearing clearance is too small for the stone crusher to cause the bearing temperature to rise too high. The selection of the grades of the lubricating oil of the stone crusher is not proper, the viscosity is too large or the viscosity is too small to form oil film, which can cause the bearing temperature to rise too high. Especially when the lubricating oil viscosity, not only increases the internal friction between the lubricating oil molecules, but also increases the friction between oil and metals, and excessive heat; improper installation of rubber plate rubber plate coupling is too thick, the stiffness, deflection, bearing friction, leading to rivalry, heat too much.

Knowing the cause of the temperature rise of the stone crusher bearing, the user can solve the problem of the temperature rise of the bearing of the stone crusher according to the reason. The user can meet the specified requirements by adjusting the bearing clearance, and the coaxial degree of the positive motor and the crusher rotor is less than 0.5mm. And using the level of the motor shaft two bearings, crusher flywheel rotor and bearing outer ring respectively for motor rotor and crusher rotor level, and then use the connecting pipe for cable crane review, hammer crusher motor and method review center line straightness, until the meet the requirements so far.

While accelerating the pace of economic development, we must also focus on the development of energy intensive processing industry and tap the great value of existing resources. The new ultrafine mill breaks through the difficult problem of slag powder processing technology, and carries out deep processing of existing slag to create new building materials and open new economic era of slag powder.

Steel smelting plant will produce million tons per year and the blast furnace slag, steel slag, common raw casting slag, manganese slag and other students. The discharge of the slag is negatively related to the ore grade, the lower the grade of the ore and the greater the amount of slag produced. There are a large number of blast furnace slag in the city occupied a large number of construction land, at the same time it will cause dust and solid waste pollution. The new ultrafine mill breaks through the difficult problem of slag powder processing technology, and carries out deep processing of existing slag to create new building materials and open new economic era of slag powder.

The application of new ultrafine grinder to slag powder has been put into operation for a year. Shanxi users said, “slag powder can effectively improve the application performance of concrete and reduce the cost of concrete production”. The ultrafine grinding machine adopts the principle of powder grinding in the super fine grinding machine, and the material residence time in the mill is short, which reduces the repeated grinding. Therefore, the iron content in the product is less, and the whiteness and purity of the product are high. The fineness of slag powder can be replaced by natural sand and gravel, and it will be replayed in highway, airport, foundation engineering, railway dregs, concrete aggregate and asphalt pavement construction.

Mine is at the forefront of all kinds of mineral resources. While accelerating the pace of economic development, we must also focus on the development of energy intensive processing industry and tap the great value of existing resources.

Ultrafine mill is a common ultrafine powder processing equipment, it is suitable for raw material, gypsum, coal and other materials, fine powder and ultra-fine powder processing. The ultrafine mill pulverizer works directly with the ore when it works, so in actual production and use, the wear of the equipment is very fast, which affects the economic profit of the user. So, how to improve the wear resistance of the superfine grinding machine powder machine?

The applicable material of the superfine grinding machine is mainly about 7 moth hardness. When the equipment is running, the flour mill mainly depends on the grinding roller and the grinding ring to grind the materials. When they are repeatedly contacted with the material in the grinding process, the pressure and friction will be more frequent, and the temperature of the contact surface will also continue to rise. Therefore, in order to improve the wear resistance of the ultrafine pulverizer, the wear resistance of the grinding roller and grinding ring should be guaranteed.

The wear resistance of grinding roller and grinding ring is mainly reflected in its toughness and hardness. So, how to guarantee its toughness and hardness? On the one hand, it should be made of high wear resistance, high hardness and high toughness. Not only the grinding roller and grinding ring, other accessories superfine grinding machine powder machine, such as blade, blade frame, bearing, gland, nut etc. to ensure the material hardness and toughness. On the other hand, it is necessary to adopt advanced manufacturing technology, reasonable casting and heat treatment process is the key factor to ensure its service life. In a word, the use of qualified materials and the formulation of reasonable production technology are the necessary conditions to ensure the wear resistance of ultrafine mill.

The production of the ultrafine mill is that the users of the market have new requirements for the grain size of the mill, so it is the symbol of the strength. Here, the Ultrafine Mill is a typical example of the whole industry. We uphold the principle of “service first” and provide users with a batch of excellent products, which makes users in the process of using no worries.

The new ultrafine mill has a competitive advantage in performance. It has been improved on the basis of the general mill, making it more durable than other mills, and more consistent with the production requirements.

First, it is efficient and energy saving. When the fineness of the finished product and the motor power are the same, it will produce more than twice the output of the airflow mill, the stirring mill and the ball mill.

Second, its safety and reliability are high: because there is no rolling bearing and no screws in the grinding chamber, so there is no problem of the bearing and its seals being damaged. There is no problem that the screws are easy to loose and destroy the machine, which is guaranteed in the safety production.

Third, its vulnerable parts have long service life: the grinding roller and grinding ring of the ultrafine grinding are made of special materials, so that the use of the ultrafine mill is greatly improved. Under the same material and finished product fineness, the service life of the worn parts is 2-5 times longer than that of the general mill, usually up to more than one year. When processing calcium carbonate and calcite, the service life can be up to 2-5 years.

Fourth, the product fineness high: the ultra-fine grinding fineness can reach D97 time less than or equal to 5 mu m.

Fifth, environmental protection and cleanliness: ultrafine grinding uses impulse dust catcher to capture dust and noise reduction by muffler. It has the characteristics of environmental protection and cleanliness, and is completely in line with the environmental standard of the home, and it can be used safely.
