After the VSI sand making machine is assembled, it is placed on the display stand of our company's sand making machine for visitors to visit our factory. VSI sand making machine is an improved model of PCL sand making machine. Its characteristics are different from that of counter-attacking sand making machine, but it is often used with counter-attacking sand making machine in making sand. First of all, to understand the technical features of VSI sand making machine.

Technical highlights of VSI sand making machine:

VSI sand making machine adopts light oil lubrication system, which can effectively dissipate heat during spindle bearing operation and prolong bearing service life. Light oil system can effectively lubricate bearing friction and improve bearing rotation speed during work, thereby greatly improving work efficiency. VSI sand making machine adopts steel plate bending heat riveting technology. The appearance of the machine body is more environmentally friendly, enhances the structural strength and toughness of the equipment, ensures the smooth operation of the equipment, and raises the quality to a whole new level.

VSI sand making machine motor balance problem solution

To find out where the VSI sand making machine motor is unbalanced, repeat the above test while rotating the rotor at the same speed in the opposite direction. Mark with another colored pencil. The midpoint between the two markers at that time determined the location of the imbalance. Place a counterweight at the other end of the diameter. The size of the balance weight should be chosen so that the vibration of the bearing is eliminated. It is also possible to cut off some of the weight in the other part of the VSI sand machine motor instead of increasing the counterweight. In order to increase the sensitivity, the machine speed can be chosen at will, so that the bearings get the maximum vibration. After the balance of the rotor is good, the bearing of this head is fixed and the bearing of the other head is loosened, and the other method is used to balance the other end.

Dolomite is abundant in my reserves, mainly in Hebei, Hubei, Guangxi, Shaanxi and other places, processing equipment is mainly used for ultrafine mill dolomite processing. Dolomite is the main basic refractories. Because it combines the characteristics of limestone and periclase, it has high alkalinity, high temperature resistance, stable thermodynamic properties, strong thermal shock resistance, and can be used to purify molten steel, resist corrosion, etc. advantage. The early dolomite refractories synthesis process used a two-step roasting method: the dolomite was directly fired into a dense sintered body at a high temperature, and was then crushed using an ultra-fine pulverizer, but the process was affected by the uneven composition of natural dolomite. Due to the high impurity content and other conditions, its performance has been greatly affected.

At present, the two-stage roasting method of dolomite is mainly used: the mixture of MgO and CaO produced by dolomite in the calcination condition of 1000°C--1200°C is called light-burned dolomite, and its activity is large and it is prone to hydration. The formation of Mg(OH)2 and Ca(OH)2 has affected their dosage and performance. When using ultrafine mill, due to the presence of hydration, refractory bricks produced from light-burned dolomite can easily absorb moisture from the air to form hydrates, which can result in the chalking of calcium-magnesia brick products. crack.

In order to enhance the hydration resistance of light-burned dolomite, secondary baking is usually performed at a temperature of 1400° C.-1500° C., and the resulting mixture after the second baking is called dead burned dolomite, which has small activity, high stability, and high crystallinity. The chemical composition is distributed evenly and the structure is compact. It also improves the hydration resistance and slag erosion resistance of dolomite refractories. It can be produced under the combined action of activated materials to obtain higher density and lower sintering temperature. Dolomite refractories. In milling by a pulverizer, modification of the dolomite surface and internal structure with additives is also required to improve the slag resistance after sintering.

Raymond Mill is also known as Raymond Mill. Because raymond mill has stable performance, strong adaptability and high cost performance, it has been popularized in the processing of non-metallic minerals since its introduction in China for more than 20 years. In order to make Raymond Mill normal, equipment should be developed. "The equipment maintenance and safety operation system" can ensure the long-term safe operation of the mill, and it is necessary to learn some of Raymond Mill's maintenance knowledge, if it is encountered in time deal with.

1. During the use of Raymond Mill, fixed personnel should be responsible for the care. The operators must have a certain level of technology. Before the installation of the milling machine, the operator must carry out the necessary technical training to understand the principle and performance of the Raymond Mill and be familiar with the operating procedures.

2, in order to make the mill normal, should develop the equipment "security equipment maintenance and operation system" in order to ensure the long-term safe operation of the mill, but also necessary repair tools and grease and the corresponding accessories.

3. After the red star machine Raymond Grinding is used for a period of time, it shall be inspected. At the same time, the wear parts of the grinding roller ring blade shall be overhauled and replaced. Before and after the use of the roller device, the connection bolts and nuts shall be carefully examined to see if Loosening phenomenon, whether the lubricating grease is enough.

4. When the grinding roller device is used for more than 500 hours, when the roller is replaced, the roller bearings in the roller sleeve must be cleaned. The damaged parts should be replaced in time. The refueling tool can be used with manual pump and grease gun.

5, fineness adjustment, according to the size of the material, soft and hard, water content, specific gravity is different, the thickness of the processing is also different, can be adjusted above the analyzer, high speed, high fineness, low speed, fineness.

If the fineness is improved, the output will be reduced accordingly. If the requirements are not met, the fan speed should be adjusted, and the user can flexibly control.

6, the scrap mill grinding ring scrap limit, the remaining minimum wall thickness shall not be less than 10mm.

7. When the Raymond Mill stops, the feed is stopped first, and the main machine continues to rake, so that the remaining abrasives continue to grind. After about one minute, the host motor and analyzer motor can be shut off and the grinding operation is stopped. Stop the blower motor to blow off the remaining powder.

As a kind of milling equipment, Raymond Mill has been used for a long time. If you do not know how to maintain it, parts in the equipment may cause damage or serious wear. In this case, Raymond Mill will vibrate.

When the raymond mill vibrates, it is necessary to check the Raymond Mill's vibration cause first: When the Raymond Mill main machine shakes badly, it should be stopped immediately to check and see Raymond Mill's grinding roller and mill. Whether the ring is deformed or not, the deformation of the grinding roller and the grinding ring will produce great vibration and noise. Therefore, the grinding roller and grinding ring should be replaced in time. In addition, the looseness of the anchor bolts, the loosening of the anchor bolts, and the host machine of Raymond machines cannot be properly fixed. When the material enters, the rotation of the motor will cause the main engine to swing and cause a large vibration failure. This occurs. Should stop immediately, tighten anchor bolts.

Of course, no matter how good the equipment still needs to be maintained, for parts of the equipment, after a period of time, it is necessary to inspect the parts of the Raymond Mill. If any wear or damage is found, replace it in time and clean it if it is not damaged. For a while, the equipment should be cleaned up once in a while to clean up the internal refuse and other substances. Only when the best maintenance plan is made for the equipment will the equipment be used for a longer period of time. Only in this way will the Raymond Mill work optimally every time.

Superfine mill is a new type of mill that has been modified. Its fineness is much higher than that of ordinary Raymond Mill. The mill is technically improved on the basis of the traditional mill and has high efficiency and energy saving. The new ultrafine mill, then its ordinary milling equipment improved in those places, the following brief introduction. The new generation of ultra-fine grinding can be applied to the processing of ore milling below 9 grade, and the humidity is below 6 percent. The fineness is adjusted directly from 400-3000 meshes. The new type of grinding system device and high-tech grading equipment have made the new type of ultra-fine grinding very popular in the market, and have been praised by users' friends.

The working process of the pulverizer: Firstly, the feeder feeds the material to the inside of the mill, and then the pulverization process is carried out under the action of the internal grinding device, and the material pulverization process between the grinding roller and the grinding ring. The qualified material passes through the lower air channel. The wind flows upwards and passes the sorting pass of the analyzer. Here, the standard of grinding four hundred meshes is the pass of 400 meshes or more. The following falls back to the inside of the mill for re-grinding, and the lower part has a blade to carry out the material. Shovel the powder between the grinding roller and the grinding ring to achieve sufficient grinding material. After the qualified material passes through the analyzer, it enters the powder collector from the pipeline, and is collected by the powder collector according to the demand. Unsuitable dust is collected in the dust collector. The new ultra-fine grinding device adopts a negative pressure system. What is negative pressure? Simply put, it is lower than atmospheric pressure. That is, the internal pressure of the mill is less than the external atmospheric pressure. Some users will worry about whether or not they will enter the feed inlet of the mill. There will be material powder out, this is generally not the case. Unless the closure of the entire system of the mill is imperfect, the superfine grinding negative pressure is converted into a positive pressure system and dusting occurs. Therefore, the user must check whether the mill is tightly closed during the application process.

With the development of our country's industry, the use of lime powder has become more and more extensive. Especially in many fields and industries, lime powder is used.
