Sand Making Machine used to produce artificial sand & plaster sand; sand manufactured by crushing,The sand making machine is specially designed for manufacturing artificial sand from the grit. It is a better utilization of the large size of rock materials and stones through rock on rock metal machine mechanism roughly as follows- Sand Making Machine,Sand Making Equipment,Sand Crusher Machine,Sand Crusher Shenyang Sanland Mining Equipment Manufacture Co., Ltd. , https://www.sanlandcrushers.com
Sand and gravel aggregate play an important role in making up building materials like concrete, which makes the separation and screening process extremely necessary.
Sand making production line is also called sand and stone production line. And the sand production line is a kind of special equipment for producing construction sand and stone. The sand making machine for sale is often needed in many fields, and this processing line can meet the requirements of simultaneous production of stone and artificial sand.
The sand manufacturing plant can crush rock, sand, gravel and other materials into various size in accord with the requirement of construction sand. Sand made by sand production line has uniform size and high compression strength, and this kind of sand is much more in line with the construction requirements than the sand processed by the ordinary hammer sand crusher machine.
Three Systems of Sand Plant Equipment:
sand plant mainly has three systems. Here is their basic information:
Firstly, the feeding system. The system send raw material to sand crusher and sand screening machine. According to crush and screen process, feeding equipment includes vibrating feeder and other types of feeding machines.
Secondly, the crushing system. The system is the heart of the whole set of sand processing equipment. The work of sand crushing plant system is to crush different varieties of ore raw materials into the required size of the finished product. A complete stone production line includes many crushers. These crushing machines have different functions, and complete the crushing operation together.
Thirdly, the screening and transporting system. The system screens the ore which are crushed by crushing machinery. In the compound sand and stone production line, sand and stone need to be separated, and the separated material needs to be transported to the respective site. The sand screening equipment used in this process is generally a Linear Vibrating Screen or other sand sieve machine.
The just-produced LED explosion-proof lamp uses high-LED light-emitting diodes as lighting source, has a long service life, good safety performance, high brightness, low power consumption, low operating temperature, wide voltage use, maintenance-free features, can completely replace the traditional explosion-proof lamp The lighting source, LED explosion-proof light is a new type of lighting fixture, which can be widely used in the safety lighting of flammable medical and explosive gas environment such as petroleum, chemical industry, factories, coal mines, tunnels and so on.
LED explosion-proof lamp is a type of explosion-proof lamp. Its principle is the same as that of explosion-proof lamp, except that the light source is LED light source. It refers to various specifics adopted to prevent ignition of surrounding explosive mixtures such as explosive gas environment, explosive dust environment, gas gas, etc. Measure lamps. One of the important principles of explosion proof LED lighting fixtures is limited, and explosive dust, explosive gases in contact with the housing surface, the surface temperature of the parts or surfaces of the electronic component and the electrical contact surfaces limit the minimum ignition temperature below its ignition temperature or temperature.
LED explosion-proof light structure:
1. The shell adopts high-tech surface coating technology, which is wear-resistant, corrosion-resistant, waterproof and dustproof, and is suitable for various harsh environments.
2, using a unique heat dissipation structure, the use of heat transfer thermal conduction to accelerate the thermal conductivity, effectively ensure that the LED heat dissipation, so that the LED life can reach 100,000 hours.
3, the unique light distribution lamp, illumination range content uniformity, the irradiation angle of 220 degrees, fully effective use of light; soft light, no glare, will not cause the operator's eyes fatigue, improve work efficiency.
4, the light source uses the world's brightest LED, the United States CREE brand, the power consumption is only 40% of the metal halide lamp.
5. All the key components of the power supply are selected with the world's top brands, which are highly efficient and stable.
6, can be connected to the line, eliminating the junction box and installation costs.
7, the highest explosion-proof explosion-proof grade, can be used in various industries flammable and explosive places.
LED explosion-proof lamp is a type of explosion-proof lamp. Its principle is the same as that of explosion-proof lamp, except that the light source is LED light source. It refers to various specifics adopted to prevent ignition of surrounding explosive mixtures such as explosive gas environment, explosive dust environment, gas gas, etc. Measure lamps.
As the LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, small heat generation, low power consumption, operating voltage is safe and low voltage, long service life, etc. Therefore, high-power white LEDs are explosion-proof lamps, especially portable explosion-proof lamps. A very ideal light source for lamps.
LED explosion-proof light , patent area sealing technology; more in line with national explosion-proof new technology. The utility model relates to an electrical equipment used in a special industry, which mainly solves the lighting problem.
