An impact crusher is a highly efficient crushing equipment widely used in the fields of mining, building materials, highway and railway construction. It mainly crushes materials through high-speed rotating hammers or blow bars that impact the material, thereby breaking hard materials such as ores and rocks. What are the advantages of this equipment? It features a simple structure, high crushing efficiency, and low energy consumption, making it suitable for fine crushing and sand-making operations of materials with medium hardness or below. Its working principle involves using an electric motor to drive the rotor to rotate at high speed. When the material enters the crushing chamber, it is struck strongly by the hammers, crushed, and then thrown onto the impact plates for further crushing before being discharged through the discharge port. The advantages of impact crushers lie in their ability to produce uniformly sized products, along with easy maintenance and flexible operation. However, they experience significant wear when processing materials with high moisture content or excessively hard materials, which affects their service life. Therefore, when selecting and using such equipment, it is important to properly configure the machine parameters based on the material properties. In summary, impact crushers occupy an important…
Choosing a concrete sand making machine requires comprehensive consideration of sand quality standards, equipment performance, production requirements and cost-effectiveness. The grading and fineness modulus of concrete sand are the core indicators. The fineness modulus should be controlled between 2.3 and 3.0, and the grading should be in line with the distribution of ‘more in the middle and less at both ends’, so as to reduce the amount of cement and improve the strength of concrete. Choosing a concrete sand making machine Huashengming Heavy Industry recommends you to use roll sand making machine. Precise particle size control, high quality of finished products Discharge uniformity: through the crushing method of double-roll extrusion and grinding. The discharge size (usually 1-5mm) can be precisely controlled to meet the high requirements of concrete sand on particle shape and gradation. Reduction of over-crushing: Compared with hammer crusher, its crushing process is gentler. Which effectively reduces the proportion of pulverised materials (the pulverisation rate is as low as less than 10%). Avoids excessive impurity content in sand and gravel, and improves the strength of concrete. Optimisation of particle size: the output sand particles are cubic. With smooth surface and reasonable grading, which can enhance the fluidity and…

The application of double roll crusher in the production of micro-fine concrete sand has significant advantages, the core of which lies in the particle size control through the flexible adjustment of roll spacing and the optimisation of crushing method. The following is a comprehensive analysis of its technical characteristics and practical effects: 1. Particle size control and adjustment mechanism Roll spacing adjustment The core of the double roll crusher is to achieve particle size control by adjusting the distance between the two rolls. The smaller the distance between the rolls, the greater the squeezing pressure on the material, the higher the degree of crushing and the finer the particle size of the discharge. Modern equipment mostly adopts hydraulic or electric adjustment system, which can adjust the pitch to 0.5-5mm range in real time to meet the demand of micro-fine sand (such as 1mm or less) production. For example, by reducing the roll spacing to less than 1 mm, fine sand that meets the standard for concrete sand can be produced. Optimisation of crushing method Tooth design: Sharp teeth for hard materials (e.g. granite) enhance the crushing effect; gentle teeth reduce over-crushing and are suitable for soft materials (e.g. limestone).
