Automation Cannot Be Separated from Control System

With the continuous development of society, the use of mining equipment slowly entered the era of automation and control area. In the modern control system, the mining equipment uses a number of new control devices and components, such as MP, MC, PC, crystal tray tube and so on to achieve the automation and control complex production process. Nevertheless, at present, the most extensive, the most basic control applied to China's industrial production is still the electrical control. Any complicated control circuit or system is composed of some relatively simple basic control links and the protection link. Therefore, mastering these basic control link is the basis to learn the electrical control circuit.

The control circuit design, the production site installation, commissioning, analysis, maintenance failure of the mining equipment, such as the mobile crusher and impact crusher, the electrical schematics plays a very important role. Analysizing and reading electrical schematics needs a process.

First, you should have the equipment to hang the impact crusher.

The installer and operator should be familiar with the structure of Impact Crusher, characteristics and technical requirement, be acquainted with the necessary operating regulation and design the proper installation flow in advance. Then Check the hole for the base bolts is coincident with the draft and other design draft. The Impact Crusher must be installed on the reinforced concrete. The height, depth and area of base should be calculated according to the local field condition. The machine also can be installed on the steel frame. The base should be flat. The crossing plane of the body and the foundation can’t leak dust and the foundation bolts should be fastened. During installation of Impact Crusher, replacing or adjusting the hammers, pay attention to its weight. In the symmetrical position, its weight difference should be limited to the minimum. Before the first start and after a long time operation, check the distance between the bottom edge of the impact plate and the top of the hammers. Make sure the distance between the front impact frame and the hammers is twice that between the back impact frame and the hammers. The installation of the thrust bearing should be same to steps of scratching. When installing air eccentric shaft,the big gear weight should be placed in the top of small gear,so that the outer end of bevel gear is alignment. 

The electrical schematics is very important for the installation of the mining equipments. As a result, we should master the knowledge of the electrical schematics to better install the mining equipments to avoid unnecessary trouble.
