The cement equipment include cement rotary kiln, cyclone preheater and grate cooler. Cement rotary kiln is the main equipment for calcining cement clinker which has been widely used in cement, metallurgy, chemical and other industries. The equipment consists of the cylinder, bearing devices, with gear wheel bearing devices, gear, activities kiln head, kiln seals, combustion devices and other components. The rotary kiln has a simple structure and reliable operation.
First, let us talk about the dry cement production process. Dry and grind the raw material or you can dry the material. After the material is grinded into raw material powder, feed it to the dry kiln to calcine it into clinker. The raw material powder can be also added some water to make it into raw material ball and send it into the Lepol kiln to calcine into clinker, which is called semi-dry method. It is still one kind of dry production.
Second, let us make a brief introduction of wet cement production process for you. After the raw material with water is grinded into raw slurry, you can feed it into the wet kiln to calcine it into clinker. You can also dehydrate the raw material produced through wet method, which is called semi-wet method. It is still a kind of wet production.
It is estimated that the total broken materials can be reached 1010t a year. The material crushing process widely used in metallurgy, coal, building materials, chemical industry, energy, transport, ceramics, pharmaceuticals, food processing, defense construction, agriculture, forestry, and many industries and sectors. Material crushing is a process of high energy consumption, high steel consumption and low efficiency. According to statistics, in many countries of the world, power consummating in breaking materials accounts for about 4% to 5% of the total electrical energy. In concentrator, crusher energy consumption accounts for about 40% to 70% of the entire beneficiation energy consumption, the ratio cannot but that huge and its position cannot but that is important. The crushing operations mission is to meet the urgent requirement on a variety of materials in number and size, particle size distribution, dissociation degree, structure, physical and chemical properties, etc. In order to meet the needs of the growing number of smash product, the requirement of large scale e crusher equipment tend upward.
With the rapid development of China”s economy in recent years, the country increases investment to perfect the basic service facilities, thus it has brought a lot of opportunities for breakneck development of cement industry. China”s cement industry has a fairly large scale through the rapid development in recent years. The cement production enterprises have turned into multiple industry from a single cement production. At the same time, the longitudinal integration of sand aggregate, concrete, cement products has become an inevitable trend in the development of the industry, and the industry will take cement as the core, take, concrete as leverage to do big industry chain of building materials.As a professional and the best mining machinery manufacturer in China, Hongxing Machinery is always ready to provide the superior horizontal lime kiln, classifiers, and these machines have the most competitive price and the most reliable quality so that they are the top choices for the high performance crushing equipment.
