At present, machine-made sand, as the mainstream sand and gravel aggregate in the market, plays an important role in the construction of various projects. As an indispensable equipment for machine-made sand, the Sand Making Machine plays an indispensable role in the production of machine-made sand.
1. Classification and characteristics of sand making machines
At present, there are many kinds of sand making machines on the market. According to the type, the sand making machine can be divided into: BVSI sand making machine, HVI impact sand making machine, VSI sand making machine, straight-through impact sand making machine. Like VSI sand making machine and BVSI sand making machine are new types of sand making equipment, the performance has been upgraded, the equipment runs stably, the failure rate is low, and the output is relatively stable. In particular, the VSI impact sand making machine has relatively excellent indexes in all aspects and is very popular in the market.
VSI impact sand making machine integrates a variety of crushing modes, which can be crushed and shaped. It is widely used in the crushing and shaping of metal ores, non-metallic ores, building materials, artificial sand and various metallurgical slag.
VSI impact sand making machine has 5 major features:
- 1. Deep cavity impeller, throughput increased by 30%
- 2. The surrounding guard can be turned up and down to extend the service life
- 3. Combined throwing head, only need to replace the worn part, which can reduce the use cost by 30%
- 4. Center and peripheral feeding, flexible adjustment, convenient conversion
- 5. The lubrication method can be selected. The modular design of the thin oil type and the grease type of the bearing chamber can realize the overall exchange.
The above are the classification of sand making machines and the characteristics of HVI sand making machines. Sand and gravel enterprises must consider many aspects when choosing, otherwise it will affect the output of the entire machine-made sand.
2. Factors affecting the output of sand making machine
In the production process of many sand and gravel enterprises, they will encounter the phenomenon of low sand output from the sand making machine, which will affect the output of the entire machine-made sand. In the following, we will analyze the internal and external factors separately.
1. External factors
①The difference of crushed materials
If the crushed material has high humidity and high viscosity, and is sent to the sand making machine for processing without treatment, part of the material will adhere to the crushing cavity, which will affect the crushing efficiency and the quality of machine-made sand, thereby reducing the output of the sand making machine. . In addition, the harder the material, the more difficult it is to make sand, and the more serious the wear and tear on the equipment. Therefore, materials with moderate hardness should be selected when selecting materials.
②Strict quality requirements for finished products
The quality of finished products is related to the needs of sand making users. When the requirements for finished products are high, the time spent per unit output will increase, and the efficiency will decrease, and the output will be low. The higher the fineness requirement of the finished sand, the smaller the sand making capacity of the sand making machine. We generally require medium fineness for materials.

2. Internal factors
①Equipment quality sharpening knives will not accidentally chop firewood. In order to increase the output of the sand making machine, we must first have a high-quality sand making machine equipment. When choosing a sand making machine, there are many aspects to consider. In addition to the brand selection and working performance of the sand making machine, the model specification, power, feed particle size, applicable materials, working capacity, etc. of the sand making machine should be consulted clearly, and then carefully compared, and the equipment that meets the production requirements of the enterprise should be selected. .
②Production plan There is no doubt that the production volume of machine-made sand is an important criterion to measure the performance of the sand making machine. In order to meet this standard, professional equipment manufacturers will tailor-made suitable production plans for customers according to the user's production requirements, production environment, equipment performance and other needs, so as to match the production and operation of enterprises. Therefore, the formulation of the production plan determines the properties of the sand making machine to a certain extent.

③Standard operation Many companies do not understand the rules of use of the equipment after purchasing the equipment, and there will always be failures of one kind or another in production. Because different types of sand making equipment have different processing capabilities, we recommend that users must strictly follow the instructions for reasonable operation and regular maintenance during the use of the equipment.
One thing to pay attention to is reasonable feeding, such as reasonable feeding speed, material hardness, feeding size and viscosity, etc., to ensure the basic normal operation, in order to ensure the smooth production of the sand making machine, and also improve the production output of the sand making machine .
Troops and horses move ahead without food and forage. In 2022, a large number of projects across the country will start construction. As the grain for major projects, machine-made sand must be adequately supplied. Sand and gravel enterprises must know how to make decisions and act later, choose suitable high-quality sand making machine equipment, and use the correct production methods, in order to achieve multiplier effect with half the effort.
