Four forms of stone powder in machine-made sand: (1) Free powder: Stone powder particles do not adhere to each other or adsorb on the surface of sand and can move freely under the action of wind and gravity. (2) Agglomerated powder: Stone powder particles are tightly aggregated together to form larger stone powder agglomerates, and the particles adhere to each other and aggregate. This type of stone powder aggregate is difficult to remove by traditional powder classification equipment due to the...
As we all know, among the reasonable and environmentally friendly configuration methods of the entire sand making production line, it is a popular trend to equip pulse dust collector and water-washed sand washing machine. In the wastewater of wet sand washing, fine and powdered sand is inevitably lost in the water flow. Each production line loses about 5%-25% of the content. Calculating the loss in a year is also very alarming. If these lost parts are collected back, this part of the profit will...
Before starting the jaw crusher, the operator needs to do some inspections to ensure that all components are normal and there is no blocking material in the crushing cavity. In addition, pre-startup inspections can also help you discover faults in time, nip them in the bud, and avoid greater losses. So, what aspects need to be checked before starting the jaw crusher? Lubrication condition Before starting the jaw crusher, check whether the jaw crusher toggle plate is sufficiently lubricated, ...
The multi-cylinder cone crusher has the characteristics of large production capacity, high efficiency, laminated crushing, excellent final product particle shape, simple operation, and high degree of automation. It is widely used in medium and fine crushing in the sand and gravel aggregate industry and mining industry, especially in medium-hard material processing systems. In the production of multi-cylinder hydraulic cone crushers, some on-site application methods can be used to effectively imp...
As the core equipment in the production process, the crusher's stable operation is crucial to the entire mining operation. Especially in the cold winter, problems such as the solidification of lubricating oil, hardening and wear of lubricating parts, and difficulty in starting equipment frequently occur, which brings considerable trouble to mining production. This article aims to reveal to you the core maintenance strategies of mining crushers in low-temperature environments, ensuring that the e...
Granite is a hard igneous rock, mainly composed of quartz, feldspar, mica and other minerals. Its Moh's hardness is 5-7 with high strength, corrosion resistance, wear resistance and other properties. After sand making treatment, granite can be made into sand with excellent grain shape and uniform particle size. This kind of sand is an important construction material that can meet the demand for high-quality aggregates in engineering construction and also provides a reliable material basis for va...
The impact crusher is a machine that uses impact energy to crush materials. Its working principle is mainly to drive the movement of the flat hammer through the rotation of the rotor, so that the materials are subject to impact, collision, friction and other forces in the crushing cavity, thereby achieving crushing. This article will introduce the operating precautions and particle size adjustment of the impact crusher for your reference. Precautions for operating the impact crusher:...
As the core equipment in mining, building materials and other industries, the jaw crusher's operating status is directly related to production efficiency and economic benefits. However, due to the harsh environment of crushing operations and long-term use, the jaw crusher is subject to high-intensity impact and friction, and its wearing parts are prone to wear, breakage and other problems. This will not only affect the performance and efficiency of the equipment but also may cause production lin...
As an important piece of equipment in mining production, the normal operation of the mining crusher directly affects production efficiency and operating costs. Lubrication is one of the key factors to maintain the good operation of the crusher. It is crucial for mining engineers and maintenance personnel to understand and master the correct lubrication methods and applicable equipment, and to identify common misunderstandings. This article will comprehensively analyze the lubrication methods of ...
In the stone production line, the hopper is an essential part that cannot be ignored. It serves the functions of feeding, transferring, buffering, and regulating. It is because of the presence of a hopper that the crushing equipment can continuously, evenly, and smoothly feed, ensuring the production process to proceed in an orderly and stable manner. There are various types of hoppers in the stone production line. This article provides a detailed introduction to the functions and styles of four...
