Introduction of cement equipment

Overview of cement equipment

Nowadays, the main cement equipment in the production process of cement plant generally includes cement ball mill, cement rotary kiln, cyclone preheater, grate cooler, conveyor, etc., but there are only two kinds of core equipment, they are Cement ball mill and Cement rotary kiln. The quality and output of these two kinds of equipment will directly affect the output of cement production line, thus affecting the benefit of cement plant. In this paper, the cement ball mill, cement rotary kiln and their corresponding manufacturers are introduced in detail, hoping to bring beneficial reference for users to choose these two kinds of equipment.

1、 Cement rotary kiln

1. Main function and composition of rotary kiln

Cement rotary kiln It is a rotary kiln used to calcine cement clinker. The cement rotary kiln is composed of barrel, transmission device, supporting device of supporting wheel and stop wheel, kiln lining, kiln tail sealing, kiln head and fuel device.

2. Application of cement rotary kiln

The cement rotary kiln has solid structure, stable operation and high output products, and can provide advanced high-efficiency vertical cylinder preheater and five-stage cyclone preheater for users. In addition to calcining cement clinker, cement rotary kiln is also used for burning clay, limestone and slag drying; in the production of refractory materials, rotary kiln is used to calcine raw materials to stabilize the size, increase the strength, and then process and shape. In nonferrous and ferrous metallurgy, iron, aluminum, copper, zinc, tin, nickel, tungsten, chromium, file and other metals are sintered and roasted with rotary kiln as smelting equipment. It is used to produce iron ore with krupsl and other methods, such as smelting iron ore with krupsl, smelting iron ore directly, smelting iron ore with krupsl process. In the process of beneficiation, the lean iron ore is magnetized and roasted in a rotary kiln, so that the original weak magnetism of the ore is changed into strong magnetism, which is beneficial to magnetic separation. In chemical industry, soda is produced in rotary kiln, phosphate fertilizer and barium sulfide are burned. This method has the advantages of low energy consumption, less electricity consumption, no sulfuric acid and low-grade phosphate rock utilization, which has been popularized quickly. In addition, in terms of environmental protection, cement rotary kiln uses cement kiln to incinerate hazardous waste and garbage, which not only makes waste reduction and harmless, but also uses waste as fuel to save coal powder and realize waste recycling.

 Rotary kiln

3. Operation principle of cement rotary kiln

The cement rotary kiln operates at high temperature with alternating heavy load and slow speed. The maintenance of its accessories and the level of thermal system control are related to the safety and efficiency of rotary kiln operation. The maintenance of transmission device is the lubrication of equipment, operation status, dynamic detection and meshing accuracy of large and small gears; the installation accuracy of supporting device determines whether the rotary kiln can operate safely and reliably. During operation, we should pay attention to the reasonable control of the load distribution of each gear supporting wheel, the layout of supporting wheel, the up and down pressure and time of hydraulic stop wheel, the force of supporting wheel, and the gap between the belt and the backing plate. The quality of sealing device directly affects the thermal system and operation cost of rotary kiln. Strengthening the daily maintenance data analysis of rotary kiln is conducive to equipment management.

4. Cement rotary kiln manufacturer

People often ask on the Internet, Cement rotary kiln manufacturer So many, the price also varies a lot, which manufacturer's equipment to choose in the end? In fact, this question is not difficult to answer. When choosing a cement rotary kiln, you only need to grasp the three selection points, and you can definitely buy the satisfactory equipment.

1) Look at the product. You can say, what do you think about the product, but you can't take it to try first. In fact, this is very simple. You only need to know the situation of the enterprise that produces this kind of product. For example, Henan Hongxing Machinery Co., Ltd. is a large enterprise with more than 30 years of cement rotary kiln production history. The accumulation of more than 30 years is enough to support the products of Hongxing cement rotary kiln. In fact, the mature and advanced design has made the cement rotary kiln produced by Hongxing machine accumulate very good among users.

2) Look at the price. Red Star machine has always adhered to the principle of reasonable price, to provide customers with cost-effective products, adhere to the purpose of integrity management.

3) Look at the service. The purpose of "Zhongxin" is to sell the machines with a close heart. Red Star machine has been following this purpose, so it has been widely praised and respected by customers.

Based on the above three points, Henan Hongxing Machinery has become a cement rotary kiln manufacturer in the industry after so many years of accumulation, and will do better and better in this field!

2、 Cement ball mill

1. Overview of cement ball mill

The cement ball mill has the advantages of large diameter, high energy consumption, large capacity and high energy consumption. Compared with the products of the same specification on the market, the energy saving rate is 40% and the output is increased by 20%. The discharge port is designed with unique design and dust removal device. The packing head can be loaded automatically, and the fineness can be adjusted according to the needs of users.

2. Practical application of cement ball mill

Cement ball mill is mainly used for grinding finished products and raw materials in cement plant, and also suitable for grinding various ores and other grindable materials in metallurgical, chemical, electric power and other industrial and mining enterprises. It can be used for open flow grinding and circular flow grinding with separator. Cement grinding tools have the characteristics of strong adaptability to materials, continuous production, large crushing ratio, easy speed regulation and grinding product fineness. Cement ball mill can be produced by dry process or wet process, and can be grinded and dried at the same time.

3. Performance characteristics of cement ball mill

The outstanding advantage of cement ball mill is the decrease of comprehensive production cost. Compared with the old cement ball mill, it has remarkable improvement in power saving function, production efficiency, failure rate, mechanization and personnel maintenance. In the past, when purchasing equipment, customers only valued the price of cement ball mill. They searched for a large number of quotation of cement ball mill from the Internet to compare. Which cement ball mill price was low would buy which one. However, a mature customer focused on the comprehensive use cost of the equipment in production, that is, cost performance. If we only look at the price of the equipment, regardless of the use cost and the maintenance cost, the cost will be several times or even dozens of times higher than the cost of buying the equipment.

4. Working principle of cement ball mill

This type of ball mill is of two type, and the transmission device is of lattice cylinder. The material enters the mill bin evenly by the feeding device through the feeding hollow shaft. There are stepped lining plates or corrugated lining plates in the bin, which are filled with steel balls of different specifications. The rotation of the cylinder generates centrifugal force to bring the steel balls to a certain height and then fall down, which has a heavy impact and grinding effect on the materials. After coarse grinding in the bin, the material enters the second bin through the single-layer partition plate, which is inlaid with flat lining plate and steel ball inside to grind the material further. The powder is discharged through the discharge grate plate to complete the grinding operation.

5. Cement ball mill manufacturer

Henan Hongxing machine is the cement ball mill manufacturer, has many years of manufacturing and processing history, red star machine research and development innovation, cement ball mill is also gradually improved, development to today, the product has been very mature, in the actual production performance is also very stable, red star machine with excellent products As a result, Hongxing has won the high-quality products and service in the cement industry.
