As the global construction industry booms and infrastructure development continues to advance, there is a growing demand for high-quality sand and gravel materials. However, traditional natural sand resources are gradually decreasing, and the pressure on environmental protection is also increasing. Against this background, mechanism sand, as an efficient and environmentally friendly alternative, has received widespread attention. Roller sand making machine has become an important equipment in the production of mechanism sand due to its unique crushing principle and excellent sand making effect. This article will deeply analyse the working principle of roll sand making machine, sand making effect and its advantages in practical application.
Roller sand making machine
Working Principle
Roller sand making machine is a kind of sand making equipment based on the principle of mutual crushing between materials, and its core component is two relatively rotating rollers. The materials are compressed, sheared and friction between the two rollers, so as to achieve crushing and sand making. The specific workflow is as follows:
1. Feeding: The raw materials to be processed (e.g. ore, construction waste, etc.) are evenly fed into the crushing chamber through the feeding device.
2. Crushing: The materials are subjected to high pressure between the two rolls, rupture and decomposition occur, forming smaller particles.
3. Discharge: The crushed particles are discharged through the adjusted roller gap to form the finished mechanism sand.
Roller sand making machine’s roll face is usually set with shims to control the crushing size of the material. Adjust the roller gap to control the particle size distribution of the finished sand to meet the needs of different projects.
Advantages of sand making
1. Particle shape and particle size control
The mechanism sand produced by roller sand making machine has uniform particle shape and regular particle distribution. As the materials mainly experience indirect crushing (materials collide with each other to crush) during the crushing process. The angle of the finished sand is higher, and it is less likely to produce too fine powder. In addition, by adjusting the roller gap and the number of separating pieces. Precise control of the grain size range of the grit to avoid problems of over-coarseness or over-fineness.
2. High Efficiency and Energy Saving
Roller sand making machine consumes less energy than traditional sand making equipment. And the energy consumption per unit product is reduced by about 30%. Its high efficient crushing efficiency comes from the mutual crushing action between materials, which reduces the waste of energy consumption in direct crushing.
3. Environmental friendliness
Roller sand making machine has low noise and dust emission during the working process, which is in line with the national environmental protection standard. In addition, through the resourceful use of industrial wastes and construction wastes, Roller Sand Making Machine realises the recycling of resources in the production process, which has significant environmental protection value.
4. Adaptability of diversified raw materials
Roller sand making machine can process a variety of raw materials, including river sand, mining rocks, construction waste, etc. It is widely used in sand and gravel production, road base material preparation and other fields.
Sand making application fields
1. Concrete for construction
Mechanism sand is an important part of concrete production. Sand and gravel produced by roller sand making machine can significantly improve the strength and durability of concrete due to its uniform particle size and excellent grain shape, especially suitable for the production of high strength concrete and decorative concrete.
2. Mortar and plastering materials
Roller sand making machine produces uniform grains of sand and gravel with high surface roughness, which can be tightly combined with mortar interface to improve the crack resistance and surface quality of the wall.
3. Roads and Infrastructure
Roller sand making machine produces sand and gravel with stable particle size and high strength, which can meet the demand of high standard projects such as highway and airport runway.
Future development trend of sand production by roll sand making machine
With the increasing demand for green materials in the construction industry, the market prospect of sand making by roll sand making machine will be broader. The future development direction mainly includes the following aspects:
1. Intelligent control: through the introduction of intelligent control system, real-time monitoring and optimisation of the crushing process can be achieved, further improving the efficiency of sand making and product quality.
2. Energy-saving and environmental protection technology: develop more efficient and environmentally friendly crushing equipment, reduce energy consumption and emissions, and meet stricter environmental requirements.
3. Multifunctionalisation: on the basis of roll sand making machine, develop compound equipment with multiple functions to meet wider application requirements.
Roller sand making machine, as the core equipment in the production of mechanism sand, has become the ideal choice for modern sand and gravel production due to its excellent sand making effect, low energy consumption, good environmental protection and other characteristics. With the continuous progress of technology and the growth of market demand, roller sand making machine sand will play a more important role in construction, road and infrastructure construction and other fields, to promote the sustainable development of the industry and the popularity of green building materials to make an important contribution.
