Cement industry should develop modern logistics and e-commerce

Core reminder: The sixth of the eight recent tasks of the Raw Materials Department of the Ministry of Industry and Information Technology in the cement industry is to use clinker as a starting point, extend the industrial chain, strengthen technological transformation, develop contract management, modern logistics, e-commerce and other productive service industries, and improve Development quality and efficiency. The first part of this work to extend the industrial chain has been proposed in the industry for many years, many cement enterprises in the upstream development of construction sand, to the downstream development of ready-mixed concrete, ready-mixed mortar has taken great steps. The latter part of the development of modern logistics, e-commerce and other producer services is the first time clear in the work points.

Fujian Construction to Build "Ecological Province" Cement Now "Production Civilization"

Fuzhou, the economically developed provincial capital city, ranked among the top three in the air quality index in the first two months of this year. During the Spring Festival, Fujian attracted 8.2298 million tourists, up 28% year on year. Travel agencies have launched "Fujian air tour". In the 10 years since Fujian proposed the goal of building an "ecological province", successive provincial party committees and provincial government teams have insisted on taking the construction of an ecological province as an important carrier for the construction of ecological civilization. While the province's GDP has maintained an average annual growth rate of 12.6 and fiscal revenue has quadrupled, The forest coverage rate continues to rank first in the country, becoming the only province in the country that maintains excellent water, atmosphere, and ecological environment.

Safety Application of Bucket Elevator in Coal Preparation

The operator shall obtain the operation qualification certificate through the professional and safety technical training of the type of work, be familiar with the structure, performance, working principle and operation method of the hoist, be familiar with the operation method of the equipment start and stop procedure, and simple inspection, analysis, prevention and troubleshooting methods, and wear labor protection articles when taking up the post. When the bucket elevator passes through the hole of the floor slab, protective railing or cover plate must be added. When checking the operation of the bucket materials and bucket, the operator should stand on the side of the bucket box. When the bucket is pressed or stuck, the machine must be stopped immediately. During treatment, no one shall stand on the front of the bucket. When the bucket is pressed and needs to be treated with water, it shall be

Bucket elevator structure and characteristics of the advantages

Bucket elevator has the advantages of high conveying efficiency, high lifting height, stable and reliable operation and long service life. The casing is transverse and small in size, and occupies a small space. The lifting height can reach 60-100m and the system has good reliability and few failures. It can realize remote display and control. In addition, it has good sealing performance and can prevent dust pollution and dust explosion. Compared with other vertical conveying equipment, power consumption is small pneumatic conveying 1/3. With the vigorous development of the construction of the four modernizations, the application of bucket elevator is more and more extensive, and has become an indispensable equipment in modern continuous conveying, suitable for conveying powder, granular and small

Structure and characteristics of chain conveyor

The head and tail bearings of the chain conveyor are moved to the outside of the shell. The hanging bearing adopts sliding bearing and is equipped with dust-proof sealing device. The bearing bush generally adopts powder metallurgy. The conveying cement adopts felt bearing bush, and the hanging shaft and screw shaft are connected by sliding block. When assembling the screw, it is not necessary to move the driving device. When assembling the hanging bearing, it is not necessary to move the screw; chain conveyor can be used as a mixing mixer. For example, several kinds of powder and granular materials need to be mixed. This equipment can be used to transport materials, which is exactly one machine with two functions. The inlet and outlet can be used according to the current work.

Selection and Maintenance of Bag Type Dust Collector

With the increasing attention of the whole society to environmental protection and energy saving, how to improve the efficiency of dust control in cement production has become a consensus. This paper analyzes the working principle, selection method, factors affecting dust collection efficiency and improvement measures to improve dust collection efficiency, and puts forward the methods of use, maintenance and maintenance. 1 Structure and working principle The main components of the 1.1 (1) Box: mainly fixed filter bags and air circuit components, made into a fully enclosed form. When cleaning ash, compressed gas first enters the box and flushes into the inside of each filter bag. According to different specifications, the box is divided

Solve the phenomenon of belt slippage of belt conveyor

Belt conveyor is a kind of friction drive to transport materials in a continuous way of machinery, not only for the transport of broken materials, can also be carried out into pieces of goods, but also with the industrial enterprises in the production process of the process requirements, the formation of a rhythmic flow transport line, widely used in a variety of modern industrial enterprises. In the process of use, the phenomenon of belt slippage sometimes occurs. The solution is as follows: the belt conveyor using the heavy hammer tensioning device can add a counterweight to solve the problem when the belt slips, until the belt does not slip. But should not add too much, so as not to make the belt bear unnecessary excessive tension

Technical specification for safety operation of bulk cement truck

1. Before loading, check and remove the ash and slagging in the tank and discharge pipeline. All pipelines and valves shall be opened and closed flexibly without blockage and air leakage. All connecting parts shall be firm and reliable before loading. 2. Before opening the loading port, the exhaust valve should be opened to eliminate the residual air pressure in the tank. 3. When loading, the switch of the material detector in the material tank should be turned on. When the material detector sends out a full-position sound call signal, the loading should be stopped immediately. 4. After loading, clean the cement accumulated on the edge of the loading port, cover the feed port cover, and insert the bolt and lock it. 5. Before unloading, the vehicle should be parked in
