Nowadays, the laying of asphalt roads is still the mainstream choice, with the characteristics of softness, durability, shock resistance, abrasion resistance, and easy recycling. Professional equipment can be used to complete the recycling of old asphalt, and then carry out new batching, crushing, screening, mixing, mixing and other operations to complete the production of new asphalt. In order to ensure the quality of new asphalt, it is also necessary to add the correct proportion of stone materials. In order to better meet the coarse and fine screening requirements, it is necessary to crush the stone materials, so it is necessary to use crushing and screening equipment to help. So, what are the good choices to use in the crushing method?
1. Use crushing method
Crushing and screening equipment can display different crushing forces for stone materials according to different application methods. Therefore, there are various methods for crushing, among which crushing is the most commonly used method. It mainly uses the friction between two planes in the crushing and screening equipment to provide a certain pressure, and then uses the internal pressure of the stone material to counteract the external pressure. After exceeding a certain strength, it can be screened by breaking from the inside.
2. Use splitting method
The main method of splitting is to subject the stone material to internal tensile stress under the splitting action of the crushing and screening equipment, and the stone material will have a certain strength bearing capacity. However, when the tensile stress exceeds the tensile strength of the stone material, it will break. Moreover, this type of stone material is more suitable for use in asphalt crushing equipment, so this method is currently used more frequently.
3. Using the method of crushing
In addition to crushing and splitting, crushing stone materials is also a commonly used method for crushing and screening equipment. This method utilizes the characteristic of multi pivot interlocking force to control the shear, bending and other reaction forces of the stone materials. When the tensile stress strength of the stone materials exceeds the bearing point, it will cause the stone materials to be sheared, bent and broken.
It can be said that the use of crushing and screening equipment is mainly to meet the requirements of asphalt crushing equipment, provide various crushing guarantees for stone materials, ensure that the thickness requirements of the discharged material can meet the production standards, and also improve the service life and quality of new asphalt, making the laying process easier. It also meets the laying standards of many industries, and is easy to operate. The parameters are set in advance, and after starting, the stone materials can be crushed, which easily ensures the standardization of crushing quality.
