Since the 1980s, the vertical shaft impact crushing Sand Making Machine has become the mainstream of the sand making machine industry abroad, and gradually replaced the sand making function of other crushers.
In the application process of sand making machine, what cannot be bypassed is China, which is the "infrastructure madman". When the sand making machine comes to China, it has a broad scope of use, and has accumulated rich practical experience in production and application. In addition, China has a large number of excellent R&D personnel and engineers, and the technology of sand making machines produced by Chinese enterprises can be continuously upgraded.
Bellian Mining Machinery Manufacturer VSI-A7 Sand Making Machine
At present, due to the large-scale use of sand in infrastructure construction in the past few decades, the amount of natural sand resources that can be exploited has greatly decreased. Many provinces have strictly restricted the mining of natural sand out of consideration for ecological and environmental protection. Rarely, there are even cases where the project stops and waits for the sand to appear. Fortunately, the country has already pointed out the direction, and it has become a trend to replace natural sand with machine-made sand. In recent years, many places have begun large-scale production and use of machine-made sand.
The market prospect is bright. How much sand can be produced means how much wealth you have. Sometimes the sand making machine becomes the key to determining wealth. How to make the sand making machine continue to produce wealth? Bellian explains how sand making machines improve service life.
Sand making site
There are many factors affecting the production of sand making machine, including external factors and internal factors, external factors such as material composition, hardness (granite hardness is large, limestone hardness is small), humidity and production methods, etc. The internal factors are mainly the equipment itself.
external factors
1. Composition of materials
The more fine powder content in the material, the more influence the sand making effect. The fine powder will be attached to the machine and affect the processing and transportation of the material; damage to components. The material should be sieved in advance to remove the fine powder in it to reduce the impact on the sand making machine; at the same time, a strong magnetic iron remover should be installed to remove iron and other sundries.
Various materials
2. The viscosity of the material
The higher the viscosity, the easier it is to stick. Materials with high viscosity will adhere to the inner wall of the sand making machine during production and need to be dealt with in time, which will reduce the working efficiency of the sand making machine and even cause the sand making machine to malfunction. Therefore, when selecting materials, we must pay attention that the viscosity of the materials should not be too large.
3. The humidity of the material
If the water content of the material is high, it is easy to adhere to the machine-made sand during production, and it is easy to block the machine during the feeding and conveying process, resulting in a decrease in the output of the sand making machine. The humidity of the material should be strictly controlled during production operations. If the humidity of the material is too high, the material must be treated with water removal, such as light and wind blowing to reduce the water content of the material.
4. The hardness of the material
The higher the hardness, the more difficult it is to break the material, the more difficult it is to make sand, and the more serious the loss of equipment will be. When selecting sand making materials, the hardness should be moderate and meet the standard of sand use, not the harder the better.
5. Matching of production line equipment
The output of sand making is related to the equipment of the entire production line. The processing capacity of jaw crusher, cone crusher, conveyor, etc. at the front end of the production line must match that of the sand making machine. There will be a problem of jamming.
6. Feeding speed and size
The coordination between the feeding speed and the processing speed is very important. If the feeding is fast, the processing and crushing is slow, and the discharging is not timely, it will lead to blockage. Therefore, when feeding the sand making machine, keep the feeding uniform and continuous to prevent the equipment from appearing. Clogging problem. If the size of the material is too large, the machine will vibrate abnormally. Therefore, the size of the material should be checked to meet the requirements of the equipment. If the size of the material is found to be too large, it should be removed in time.
7. Discharge port adjustment
In the production process of the sand making machine, if the equipment discharges the material too slowly, the crushed material will accumulate in the discharge port and the crushing cavity, resulting in the problem of discharge accumulation. The discharge port should be checked and adjusted frequently during production.
Internal factors
1. Lubrication of equipment
Whether the lubrication of the equipment is sufficient or not determines the production efficiency of the equipment and the service time of the equipment. The oil station is the core of the lubrication equipment. It is necessary to regularly pay attention to the return temperature of the lubricating oil, check the quality of the return oil, and focus on whether the key parts of the equipment are properly lubricated. .
Equipment lubrication should focus on the following aspects: the quality of lubricating oil, if iron filings, dust and other impurities enter the lubricating system, it will contaminate the lubricating oil, cause the lubricating oil to deteriorate, and then lead to lubricating failure; the lubricating pipeline is blocked, resulting in the production of If the impurities enter the system pipeline, it will cause the blockage of the oil supply pipeline or the oil return pipeline, and the lubricating oil cannot reach the lubricating part; the selection of lubricating oil, the lubricating oil of different quality should be selected in different seasons of temperature, and the viscosity can be slightly lower in winter. lubricating oil with slightly higher viscosity can be used in summer.

2. The balance of the equipment rotor
The unbalance of the rotor parts will cause the rotor unbalance and cause the machine to vibrate. For example, when replacing parts, pay special attention to such things and pay attention to the corresponding balance of the parts, otherwise vibration will occur during operation.
3. Tension of V-belt
The V-belt plays the role of power transmission, which is particularly important for the dual-motor drive equipment of the sand making machine. When the tension of each V-belt is inconsistent, the wear degree of the V-belt will be different, and accidental breakage will occur, which will also lead to The load of the two motors is inconsistent, and the current level is inconsistent, which affects the performance of the motor. The V-belt should be inspected and replaced regularly. Generally, it is a one-time replacement. Select the same type of product from the same manufacturer. After the replacement, the new V-belt should run idly for a while, and then the feeding operation will be carried out after the tension adjustment.
The above are the aspects that need to be paid more attention to during the use of the sand making machine. Bellian mining machinery manufacturer has accumulated rich experience in on-site production for many years, and has continuously optimized and improved equipment. The VSI-A7 and HVI series of high-quality sand making machines have become a veritable "sand factory warrior" and are widely used. In the production line of sand making at home and abroad, and Bellian's engineers provide customers with detailed experience guidance in all aspects, so that customers can obtain satisfactory production results.
