Is the surface roughness of the slewing bearing as small as possible? Surface roughness refers to the small spacing and the unevenness of small peaks and valleys that the machined surface has. The roughness of the bearing surface may affect the wear resistance, stability, fatigue strength, stability and other properties of the bearing. Generally speaking, the smaller […]
Mining vibrating screen is a kind of large-scale screening equipment, commonly used in the mining industry, etc. The use of this vibrating screen to screen materials generally requires relatively large output. In use, we also hope that the larger the output of the equipment, the better. Since the models and specifications produced by each vibrating screen manufacturer […]
The vibrating screen exciter is an important component that utilizes mechanical vibration. The exciter can make the excited object obtain the vibration amount of the form and size, so as to conduct vibration and strength tests on the object, or calibrate the vibrating screen and sensor. The vibrating screen exciter can also be used as an excitation component to […]
Impact crusher is a crushing machine that uses impact energy to crush materials. It can handle materials with a side length of 100-500 mm or less, with a compressive strength of up to 350 MPa, with a large crushing ratio, and the crushed materials are cubic particles. Widely used in building materials, ore crushing, railways, […]
One of the most important aspects of environmental protection is to control noise pollution. Noise pollution is a common problem in the machinery industry. The noise of concrete mixer trucks are composed of mechanical noise and motor noise. When the feeding system of the mixer feeds the stones, sand, cement and water into the conical mixing drum […]
It’s summer now, and basically it’s time for the heat. In such an environment, some materials will crack due to excessive temperature, so what is the maintenance method of the dense rack in the hot summer? Due to the difference between manual compact racks and intelligent compact racks, it is also necessary to distinguish them […]

This kind of paper bag is produced by the square bottom machine. Then the installation and debugging of the bottom of the square bottom machine If you […]
Calcium hydroxide powder selection is to make the extracted calcium hydroxide mesh more pure. There are many kinds of powder separators, such as centrifugal, three-separation, fly ash and other different types. Qualified powder is selected. In the process of calcium hydroxide production, even if it is produced by professional calcium hydroxide production line equipment, it is […]
The use of school desks and chairs will have a greater impact on schools and students, so there are many aspects that need to be paid attention to when configuring desks and chairs. So how to correctly choose school desks and chairs manufacturers? How to choose the school desk and chair manufacturer correctly 1. First […]
The raceway of the slewing bearing generally needs to be heat treated. In the heat treatment process, because the diameter of the raceway circle of the slewing bearing is relatively large, flame surface quenching is usually used. The method is to use acetylene to heat the surface of the workpiece to be hardened and then add water […]
