With an increasing demand for construction sand inside and outside China, the sand making plant is more and more popular among our customers. So we will give you a glance to the sand making plant.
Generally speaking, a complete ultrafine mill includes a jaw crusher, one or two impact crushers, a sand making machine or sand crushing machine, a vibrating screen, a vibrating feeder and several belt conveyors.
We just focus on some key products. Let’s start with the jaw crusher. The jaw crusher is usually the coarse crushing machine, which is used to crusher big rock bulks to smaller stones. The vibrating feeder ensures the smooth feeding process and the big outputs featured by the jaw crusher is definitely able to meet the requirement.
After the jaw crusher, these somewhat irregular cobblestones will enter the impact crusher for secondary crushing. The impact crusher will crusher these stones into relatively regular cobblestones due to its excellent reshaping function. After this step, the sand making machines can crush these cobblestones into qualified sand. The vibrating screen will classify these materials into two stockpiles: qualified and unqualified. The qualified sand can be stocked as finished produces while the unqualified one will be sent back to the crusher for re-crushing until they reach the standard.
That powder grinding mill is widely used in cement production process has been familiar with use, then how is a ultrafine mill used in cement production? With this question, we come to the large production base of mining machinery in Henan Province, Henan Hongxing Mining Machinery Co., Ltd. to consult the experts here, and the experts responsible for the production of powder grinding series products answers this question in detail.
The main task of ultrafine mill in the cement production line is to crush the raw ores to the specification conforming to the feeding size of the grinding plant and make preparation for the next production procedure.
In our country, common cement plants all have their own mines and they often choose ore transportation equipment according to the distance between quarry plants and cement processing plant. Generally speaking, if the distance is within 300-500m, belt conveyor will be used for transportation and within 3km, unloading automobile or small diesel locomotive will be used.
Large stone materials are first coarsely crushed in jaw crusher and then they will be further crushed by ultrafine mill. After stone materials are crushed to the specification conforming to the feeding size of the powder grinding plant, they can be sent to milling machines for grinding. The crushing of stone materials mainly adopts four methods: crushing, shredding, grinding and splitting. Limestone is raw material with the highest use in cement production, and due to its big size and high hardness, crushing procedure plays a crucial role in the cement manufacturing process.
Such machines as jaw crusher, ultrafine mill and grinding mills produced by Hongxing Machinery serve cement production line all the year around and have good public reputation among customers and are indispensable machines in cement production.
Recent years, the producing technology of sand making machine has not been the industrial secret, but it is the first time to apply solar energy in ultrafine mill. As we all know, the sand machine is always exposure in the sunshine for the whole day, so it’s not impossible to use the solar energy to charge its generator.
Solar Energy, usually refers to the sun radiation Energy, in the modern society, generally used for power generation. Since the earth created creatures, those creatures depended on the heat and light of the sun, band also human beings knew to dry the objects in the sunlight, by which they kept food, such as salt-making and drying of salted fish, etc. But with the reduction of fossil fuel resources, then people are disposed to develop solar energy further. The methods of solar energy using include passive use (solar-thermal conversion) and photoelectric conversion. Solar power is a new kind of renewable energy. In the broadest sense, the solar energy is the resource of much earth energy, such as wind power, chemical energy, and water potential energy and so on.
Solar energy comes from the earth’s outer universal bodies (mainly solar), most of the energy human need is directly or indirectly, from the sun. Rightly all kinds of plants, through photosynthesis, convert solar energy into chemical energy, storing the energy in plants body. Coal, oil, natural gas and other fossil fuel ware formed from the buried plants and animals under the ground after a long geological generation. These are, in essence, the fixed solar energy of those ancient creatures. In addition, hydropower, wind energy, are also transferred from the solar energy. The solar power system, the earth itself, reserves of energy which usually refers to the energy related with the interior earth heat energy and that relevant nuclear core source energy.
And what is related with the nuclear reactions is nuclear power. When the structure of the nucleus changes, it will release a large amount of energy, called atom nuclear power, hereinafter referred to nuclear energy, commonly known as the atoms power. It originated from the nuclear fission resource from the uranium and plutonium in the procedure of nuclear fission reaction, including the fission can resources of the tritium lithium deuterium stored in the sea. These substances release energy during nuclear reactions. At present the biggest use of nuclear energy is generating electricity. In addition, it can be used for other types of power supply, the heat source, etc.
Through the introduction, we know that the ultrafine mill applies solar power to generating electricity, so as to achieve self-sufficiency, which is completely feasible. If you are interested in our product, call our customer service number for detailed questions.
Bearing is an important part of a machine, different bearings are not the same role, but in general, the main bearing the following role: the transfer of energy, bear the weight.
The internal bearings of ultrafine mill produced by the company also bear the above two kinds of functions, and the customer needs to understand that the machine parts are through the installation of mutual cooperation and realize the operation, so the various parts can not operate alone, and the interaction between the components will produce a certain force, and for the bearing, When it transmits energy, the force is friction, and when the friction is relatively large, the bearing will inevitably wear out and fail.
Generally, in order to reduce the bearing wear failure probability, we will lubricate the bearing, in order to reduce the friction between bearings and other parts, thus playing the role of protection bearings. The company developed ultra-fine Flour Mills are using advanced technology, that is, automatic oil lubrication technology, through the lubrication station connected with the machine to provide lubricating oil bearings, so as to achieve the bearing lubrication, reduce bearing wear failure and reduce the customer manual operation
Along with the rapid development of the infrastructure construction of bridges, railways, highways, buildings, house demolition, the demand for high-quality aggregate is increasing; artificial sand equipment is the key equipment for the production of artificial concrete aggregate, whose performance directly affects the quality of the concrete aggregate and affects investment and production costs of artificial aggregate processing system. There are a wide range of crushing and sand making equipment manufacturers at home and abroad, their performances and prices are also vary. How to choose the right crusher and ultrafine mill to ensure the operational reliability advanced technology, economic rationality of the system of artificial sand production is the main topic for artificial sand production designing system.
