VSI High Efficiency Vertical Shaft Impact Sand Making Machine Introduction

Preface: In modern industrial production, sand making equipment plays a vital role. As an advanced sand making equipment, VSI high-efficiency vertical shaft impact sand making machine has been widely used in many fields such as construction, roads, bridges, etc. due to its high efficiency and high-quality sand making performance. This article will give a comprehensive and in-depth introduction to VSI high-efficiency vertical shaft impact sand making machine, so that everyone can have a clearer understanding of it.

1.Working principle

VSI vertical shaft sand making machine

VSI high-efficiency vertical shaft impact sand making machine adopts the advanced principle of stone hitting stone and stone hitting iron. When the equipment is working, the material enters the sand making machine from the feed hopper, and is divided into two parts by the distributor. One part enters the high-speed rotating impeller from the middle of the distributor, and is rapidly accelerated in the impeller, with an acceleration of hundreds of times the acceleration of gravity, and then is ejected from the three evenly distributed flow channels of the impeller at a speed of 60-70m/s. First, it is impacted and crushed with a part of the material that falls freely from the surrounding of the distributor, and then it impacts the material lining in the vortex branch cavity together, is rebounded by the material lining, and impacts obliquely upward to the top of the vortex cavity, and then changes its direction of movement, deflects and moves downward, and the material emitted from the impeller flow channel forms a continuous material curtain. In this way, in the vortex crushing cavity, the material is subjected to two or more collisions, friction, grinding and crushing, and the crushed material is discharged from the lower discharge port. By adjusting the position of the distributor, the proportion of materials entering the impeller and falling from the surrounding of the distributor can be adjusted, so as to achieve different crushing effects and sand making particle sizes.

2. Structural features

Unique impeller structure: The impeller is the core component of the VSI sand making machine and adopts a special design. Its internal flow channel is smooth, which can evenly accelerate the material in the impeller and reduce the wear and blockage of the material. At the same time, the impeller is made of highly wear-resistant materials, which increases the service life of the impeller and reduces the maintenance cost of the equipment.

Advanced distributor: The distributor can accurately control the distribution ratio of the material to ensure that the material is fully crushed and sanded in the sand making machine. Its structure is simple and easy to adjust, and it can be flexibly adjusted according to different production needs.

Reliable bearing assembly: The sand making machine adopts high-performance bearing assemblies, which can withstand huge impact loads and centrifugal forces generated by high-speed rotation. The bearing assembly adopts advanced sealing technology to effectively prevent the intrusion of dust and moisture, ensuring the normal operation and service life of the bearing.

Sturdy body structure: The body is made of high-strength steel with good rigidity and stability. During the operation of the sand making machine, it can withstand the strong impact and vibration of the material to ensure the safe operation of the equipment.

3. Performance advantages

High sand making efficiency: Due to the advanced working principle and unique structural design, VSI high-efficiency vertical shaft impact sand making machine can make a large amount of materials into sand particles that meet the requirements in a short time. Its production capacity is 30% - 50% higher than that of traditional sand making machines, which greatly improves production efficiency and reduces production costs.

Good sand making quality: By accurately controlling the crushing process of materials and the particle size of sand making, the sand making machine produces sand particles with regular shape, uniform particle size and low stone powder content, which can meet various high-standard construction sand needs. The concrete made with it has good workability, fluidity and strength, which improves the quality of construction projects.

Low operating cost: On the one hand, the high efficiency of sand making reduces the energy consumption per unit output; on the other hand, the wear-resistant parts of the equipment are made of high-wear-resistant materials, with a long service life, which reduces the frequency and cost of replacing parts. At the same time, the maintenance of the equipment is simple and convenient, which further reduces the operating cost.

Excellent environmental performance: VSI sand making machine fully considers environmental protection factors in its design. It adopts advanced sealing technology and dust collection devices to effectively reduce dust emissions and reduce pollution to the environment. At the same time, the equipment has low noise during operation and meets national environmental protection standards.

4. Application fields

Construction industry: It is the main production equipment for construction sand. The high-quality sand produced can be used for the preparation of high-performance concrete, foundation pouring of high-rise buildings, wall masonry, etc., providing a solid material foundation for construction projects.

Road and bridge construction: It is used to produce gravel for road base and subbase, sand for bridge concrete, etc. The sand and gravel produced have good gradation and strength, which can improve the bearing capacity and durability of roads and bridges.

Water conservancy and hydropower projects: In water conservancy and hydropower projects such as dam construction and river regulation, a large amount of sand and gravel is required. VSI sand making machine can produce sand and gravel that meet the requirements of the project and meet the strict requirements of water conservancy and hydropower projects for materials.

Industrial fields: In industrial fields such as glass manufacturing, ceramic production, and refractory materials, high-quality sand is also needed as raw materials. The sand produced by VSI sand making machine can meet the requirements of these industrial fields for raw material particle size and purity.

5. Operation and maintenance

Operation points: Before starting the equipment, it is necessary to check whether the various parts of the equipment are firmly installed, whether the lubrication system is normal, and whether the electrical system is intact. When starting the equipment, it should be started without load first, and then gradually feed after the equipment runs stably. During operation, pay close attention to the operating status of the equipment. If abnormal sounds, vibrations or excessive temperatures are found, the equipment should be stopped immediately for inspection. When shutting down, the feeding should be stopped first, and the power supply of the equipment should be turned off after all the materials in the equipment are discharged.

Maintenance: Regular maintenance of the equipment is the key to ensuring the long-term and stable operation of the equipment. The wear-resistant parts of the equipment, such as impellers, distributors, vortex chamber linings, etc., should be checked regularly. If serious wear is found, they should be replaced in time. At the same time, the lubrication system of the equipment should be checked and maintained regularly to ensure that each lubrication point is fully lubricated. In addition, the dust and debris inside the equipment should be cleaned regularly to keep the equipment clean.

PS: VSI high-efficiency vertical shaft impact sand making machine has become the preferred equipment in the modern sand making industry with its advanced working principle, unique structural design, superior performance advantages and wide application fields. It not only improves the efficiency and quality of sand production, but also provides reliable material guarantee for the development of various industries. With the continuous advancement and innovation of technology, I believe that VSI high-efficiency vertical shaft impact sand making machine will play a more important role in future industrial production.
