Qualification of asphalt concrete mixing plant

Qualification of asphalt concrete mixing plant 1. When the material hardness is not more than 150MPa, in order to save customer cost and improve work efficiency, one-time molding equipment is generally used. The main equipment includes: vibrating feeder high-efficiency composite concrete mixing station (i.e. two in one concrete mixing station, which can achieve the ideal particle size of large materials through special design, which is generally hammer type mixing The concrete mixing station, vibrating screen and finished stone are transported by belt conveyor in the middle. The production mode is basically a spade and a sieve. There are few or no large-scale machinery or complete sets of equipment. The surrounding area of the production site is sparsely populated and the traffic is inconvenient. Therefore, it is of great significance for the normal operation of the concrete mixing plant to control the large ore and non mixing materials falling into the machine and keeping the ore feeding evenly. When the abrasion reaches a certain degree, the rotor rotates in the opposite direction. At this time, the concrete mixing plant of great wall construction machinery works by using the other end of hammer and the lining plate and sieve plate of the other side, so that the service life of continuous work can be almost doubled. The huge investment in infrastructure construction machinery of the great wall and the continuous acceleration of urbanization have stimulated the sensitive nerves of giants and Chinese construction machinery enterprises. It is widely used in mining, smelting, building materials, highway, railway, water conservancy and chemical industry. The development of the industry provides a huge space for the development of different mixing and screening equipment. At this time, the types and models of equipment constantly appear to meet the needs of different levels of demand, basically meet the needs of the development of China's gravel industry, and promote the continuous expansion of the scale of sand and gravel production enterprises.

For example, the grade of copper concentrate increased from 18% to 27% and the grade of lead concentrate increased from 45.5% to 59.3% by 14%, and the recovery rate of mineral was also improved accordingly. A suitable grinding medium steel rod is installed in the cylinder. The concrete mixing station consists of fixed jaw plate and movable jaw plate. When the two jaw plates are close to each other, the material is mixed. When the two jaw plates leave, the material block smaller than the discharge port is discharged from the bottom. Some jaw concrete mixing plants also directly use hydraulic transmission to drive the moving jaw plate to complete the mixing action of materials. The inspection records of each process shall be complete and accurate, and shall be used as the data of completion and acceptance.

The eccentric shaft is bent by centrifugal force produced by eccentric mass of qualified vibration exciter in asphalt concrete mixing plant, which leads to relative deflection of inner and outer rings of bearing. Due to eccentricity, vibration caused by rotating frequency and its harmonic frequency will be generated. Therefore, inertia force and inertia couple generated in operation will cause dynamic reaction force and vibration of bearing, destroy the stable working state of bearing and other parts High frequency vibration. This is because there will be a large acceleration at the impact point of the rolling element and ferrule. In order to achieve energy conservation and emission reduction, and make rational use of construction waste resources, Shandong Province promulgated the notice of the general office of the people's Government of Shandong Province transmitting the opinions of the provincial economic and Information Commission and other departments on further improving the comprehensive utilization of construction waste, which has laid a solid foundation for the transformation of comprehensive utilization of construction waste into new building materials in terms of technology and policy. The production line process adopts two-stage stirring + screening + ball milling process. In case of gravel mixing station, the use of concrete mixing plant will cause serious damage, such as the use of concrete mixing plant, gravel plate, etc., which will cause serious damage. It was put into operation in 1992, and the coal particle size was more than 0 mm (mmd1250 concrete mixing station product). It has opened up a new way for the development of circular economy and a resource-saving and environment-friendly society. In general, the large-scale equipment is easy to be polluted by dust and oil in the environment of large-scale oil, so it is very easy to operate the large-scale equipment with low lubricating oil consumption in the external environment In the case of bad environment, the performance will not change greatly. The customer used to use 8 PEX fine jaw concrete mixing stations, and the cost of wear-resistant parts replacement was as high as 100000 yuan per month. The customer replaced 8 jaw concrete mixing stations with 2 sets of PSG hydraulic cone concrete mixing stations of Changcheng construction machinery and mining machinery instead of 8 jaw concrete mixing stations. The price of a set of wear-resistant parts was less than 20000 yuan, and the cost of wear-resistant parts per month was reduced by 90% A considerable benefit!.
