Plate feeder purchase guide

Plate feeder is a necessary equipment for cement production line, and it is most widely used in cement industry and mining industry. The general manufacturer only pays attention to the inclination angle required by plate feeder customers, the capacity of supporting crushing equipment and the feed granularity. However, for a real customer, the concern is not these. The focus of the investigation is not to put the cart before the horse. Problems such as inclination angle, production capacity of supporting equipment and feed size may be the concerns of manufacturers when selecting users, but the concerns of customers are often not these, but some faults that may occur in product quality and use, such as welding.

Causes of Blocking of Raw Material Conveying Slant and Preventive Measures

1 conveying chute structure and characteristics of air conveying chute is an extraordinary form of continuous pneumatic conveying device, conveying dry powder material pneumatic conveying equipment, in the cement industry is often used to transport cement and raw material powder. The chute is widely used in conveying materials because there are no rotating parts, easy maintenance, good sealing, no noise, safe and reliable operation, low power consumption, convenient change of conveying direction, and multi-point feeding and multi-point unloading. The main body is connected by several sections of upper and lower two layers of grooves made of thin steel plates, which looks like a "day" from the cross section, as shown in Figure 1.

Cement dust selection technology and guide

Dust collection technology and equipment of 1. cement plant 1. Difficulties in smoke and dust control The main dust emission sources of cement plant are crusher, rotary dryer, vertical dryer, raw mill, powder separator, cement mill, vertical kiln, packaging machine, etc. In addition, the conveying equipment, the top of the warehouse, the bottom of the warehouse, the inlet and outlet, etc. are the dust sources that produce the dust of the post. Among them, the treatment of shaft kiln exhaust gas is more difficult. The smoke and dust control of vertical kilns is mainly difficult in the special working conditions of "wet, eroded and variable" flue gas, not in the large amount of smoke (much smaller than the amount of waste gas at the end of rotary kiln), nor in the high dust concentration (vertical mill and O-sepa separator

The Latest Development Trend of Automation in Cement Industry

1 information technology to promote enterprises to achieve automation control to information technology to transform the cement industry, to promote automation, automation and then promote energy saving, environmental protection, safety, high efficiency of the four goals, has become the consensus of the industry. In today's automation field, from the process site layer to the factory (group) management layer can basically realize the smooth and seamless flow of information through Ethernet. The so-called "modern integrated production process" combines information technology, network technology and modern new processes and is applied to all stages of the enterprise product life cycle. Through the seamless integration of information, process optimization and resource optimization, logistics and information can be realized.

Building materials industry: industry policy is good to focus on conch cement.

The Ministry of Industry and Information Technology has formulated the "Twelfth Five-Year Plan for the Comprehensive Utilization of Bulk Industrial Solid Waste". The plan requires that by 2015, the comprehensive utilization of bulk industrial solid waste will reach 1.6 billion tons, the comprehensive utilization rate will reach 50%, the annual output value will be 500 billion yuan, and 2.5 million jobs will be provided. It is estimated that the project involved will require a total social investment of 100 billion yuan, with an annual output value of 144.5 billion yuan and an annual utilization of 412.1 million tons of bulk industrial solid waste. This week's key company dynamics (1) AVIC Sanxin on the wholly-owned subsidiary Shenzhen Sanxin Curtain Wall Engineering Co., Ltd. capital increase and share expansion matters involving related transactions.

Building Materials Cement Industry 2012 Annual Strategy: Integration Promotion, Performance Differentiation

Investment tips: In 2012, the supply and demand of the cement industry were basically balanced. From 2010 to 2011, the fixed asset investment in the cement industry increased by 3% and-12% respectively. It is expected that the fixed asset investment in the cement industry will continue to decline by 15% and 10% respectively in 2012 and 2013. It is estimated that in 2012, cement demand will increase by 6% (optimistic up to 8.1), effective production capacity will increase by 4.7 (60 million tons of backward production capacity will be eliminated), supply will increase by 5.8, and supply and demand will be basically balanced. In 2013, cement demand is expected to increase by 5.5 and effective production capacity by 3.1 (backward production capacity elimination 300

China Building Materials Group to build the cement industry "aircraft carrier fleet"

Ten days ago, China National Building Materials Group Co., Ltd. established Southwest Cement Co., Ltd. in Chengdu. This is a further expansion of its cement map following the successful establishment of Zocong Cement, Southern Cement and Northern Cement: in the next 2-3 years, more than 100 enterprises will be reorganized and integrated in the southwest market. "Restructuring comes at the right time." Looking at the many strange and expectant faces in the audience, Song Zhiping, chairman of China Building Materials Group, had mixed feelings and felt that the burden on his shoulders was much heavier. From operating income of more than 2 billion yuan ten years ago and operating in debt to becoming a leading enterprise in the domestic building materials industry and one of the world's top 500 enterprises and operating income

The Ministry of Industry and Information Technology issued the "Twelfth Five-Year Plan" to eliminate backward production capacity target cement industry 0.37 billion tons

According to the website of the Ministry of Industry and Information Technology, the Ministry of Industry and Information Technology recently issued the target task of eliminating backward production capacity in 19 key industries in the industrial field during the "Twelfth Five-Year Plan" period. Compared with the "Eleventh Five-Year Plan" period, copper smelting, lead smelting, zinc smelting, tanning, printing and dyeing, Seven industries including chemical fiber and lead battery have been added. On December 26, 2011, the Ministry of Industry and Information Technology issued to the people's governments of all provinces, autonomous regions, and municipalities directly under the Central Government the target tasks of eliminating backward production capacity in 19 key industries in the industrial field during the "Twelfth Five-Year Plan" period (Ministry of Industry and Information Technology Industry [2011] No. 612). At the same time, all localities are required to conscientiously implement the implementation plan for the work assessment of eliminating backward production capacity.
