Summary: in the actual production, there are many factors related to the output of sand making machine such as: the hardness of material, humidity, finished sand fineness, equipment quality, and so on....
Many users always complain about the low output of their sand making machine after purchase and want to know the reason. In actual production, there are many factors affecting the output of the sand making machine, such as material hardness, moisture content, finished sand fineness, equipment quality, and so on. But 7 of them are the most crucial. The details are as follows:



1. Different raw materials
Different raw materials have different hardness, viscosity and humidity. So the output of the sand making machine will also be different according to the different materials.
- 1) Viscosity of material
The greater the material viscosity, the easier it is to adhere. Materials with high viscosity will adhere to the inner wall of sand chamber in sand making machine. If not cleaned in time, the working efficiency of sand making machine will be seriously affected and even the normal operation of sand making machine will be affected. Therefore, it should be noted that the material viscosity should not be too large. - 2) Powder Content
The higher the powder content in the material, the more it affects sand production, because these fine powders are easy to adhere and affect transportation. Therefore, the material with more fine powder content should be screened in advance, and the fine powder should be screened out from the material as far as possible, so as not to affect the work of sand making machine.
- 3) Material humidity
When the material is crushed in the sand making machine, materials with higher water content are easy to adhere, which may cause blockage and delivery failure, resulting in reduced output of the sand making machine. So when selecting materials, the humidity of materials should be strictly controlled. If its humidity is too high, we can reduce the moisture in materials by sun or air drying.
- 4) Material hardness
The harder the material, the harder it is to sand and the faster the equipment wears down. This shows that we should select materials of moderate hardness.
2. Design of sand production line
The output is also related to the equipment in the whole production line. The configuration of a production line should consider all factors comprehensively. For example, if you want to produce 500 tons of sand an hour, it cannot only require the output of sand making machine to reach 500t. Other equipment like jaw crusher, cone crusher, belt conveyor and so on should be matched to work together. Otherwise, that is unable to meet the production requirements.
3. Machine Type
Each type of sand making machine produced by various manufacturers comes in different sizes and specifications. The capacity and power of different types of equipment are not the same. When purchasing equipment, we should have an understanding of their basic production or you may get a wrong product which not only affect the output, but may cost you higher.
4. Quality of machine
Sand making machine with high quality not only has advantages on comprehensive performances, but has advantages on energy saving and environmental protecting. It can easily achieve the expected output. Because this kind of equipment is made of new wear-resistant materials and advanced production technology, it can well meet production needs.
5. Speed of Impeller
In a vertical shaft impact crusher, there is a relation between the input size of material and the linear velocity of rotor.
Under the same working conditions, if the particle size of the raw material is larger, the linear speed of the crusher rotor will be lower. Therefore, under the same condition of particle size, water content and feed amount of incoming material, the rotor speed (linear speed) of sand making machine can be appropriately increased. It is thus no surprise to help raising production.
6. Standard operation and periodic maintenance
It is very important to maintain proper operation and regular maintenance of the machine, as this also affects the sand output.
Continuous and uniform feeding can not only ensure normal production, but improve the productivity. If users do not perform regular maintenance, it will cause wearing parts to wear faster and greatly reduce the equipment life, all of which leads to low output.
7. Requirements on fineness of finished sand
This is also for a special reason. The greater the fineness requirement (the finer the finished material), the smaller the sand production capacity. This is up to what kind of fineness you want.
In conclusion, that sand making machine can't reach the original output is related to the above 7 factors. So when choosing a machine, users need to consider their own conditions. We believe that as long as these factors are taken into account—selecting the right equipment, correct operation, and frequent inspection and maintenance—sand production can be effectively improved.
