Introduction to the production process of emery

Emery is a kind of artificially synthesized silicon carbide, which has good thermal conductivity, stability and wear resistance, so it is widely used in metallurgy, building materials, ceramics and steel industries. How much do you know about its production process? Here is a detailed summary for you:

⑴, raw material crushing

Hammer crusher is used to crush petroleum coke to the particle size required by the process.

⑵, ingredients and mixing

Batching and mixing is the process of weighing and mixing according to the prescribed formula. The platform is used for batching, and the concrete mixer is used for mixing. The batching and mixing operations of petroleum coke and quartz sand are carried out according to the process requirements.

⑶, silicon carbide electric furnace preparation

Electric furnace preparation is to refurbish and reorganize the furnace that was used last time, so as to put it into use again. The work content includes cleaning the bottom material of the furnace, repairing the electrodes, cleaning and repairing the furnace wall, removing the loading force and the first gear, checking and eliminating other defects of the furnace.

⑷, Furnace loading

Furnace loading is to fill the furnace with reaction material, insulation material and furnace core material according to the specified furnace material category, location and size, and build the melting furnace side wall with the functions of heat preservation and material storage.

⑸, power transmission smelting silicon carbide

After the smelting furnace is connected to the transformer, electricity can be transmitted. 15 minutes after the start of power transmission, an open flame is thrown to ignite CO, and the smelting process lasts for 170 hours.

River Water Cyclone Desander

 A cyclone desander is a sand removal device that combines cyclone flow and filtration. It is primarily used to remove solid particles and sediment from groundwater, including groundwater and other water sources. It is suitable for water-source heat pump systems, central air conditioning circulating cooling water, chilled water systems, winter heating and cooling circulating water systems, and industrial cooling circulating water systems. It is widely used in many industries, including the chemical, environmental protection, and food industries, achieving remarkable results in water treatment, including sand removal, turbidity reduction, solid-liquid separation, and sediment separation. Cyclone Desander Concept: A cyclone desander, also known as a cyclone desander or desander, is a device that uses the principle of screening solid particles in the medium as they rotate within the desander. Combining cyclone flow and filtration, it achieves remarkable results in water treatment, in...

Water-Saving Sand Washing Plant

Choosing water-saving equipment and integrating recycling functions is the key to fundamentally reducing water consumption. Select advanced sand washing equipment Bucket-type sand washing machine: The structure is simple, with almost no wearables except for the screen, and the failure rate is low. It adopts a circulating water cleaning method and is one of the relatively more water-efficient mainstream choices currently. Integrated sand washing equipment: This type of equipment integrates sand washing, fine sand recycling, dehydration, and even wastewater treatment functions into one, significantly simplifying the process flow. For example, some new equipment uses built-in bubble flushing technology to improve the flushing effect and avoid secondary cleaning waste caused by incomplete cleaning. Mandatory water recycling system Modern sand washing equipment usually comes with a water recycling system, which can collect, filter, and reuse water during the cleaning cycle. This approach ca...

The difference between quartz and mica

Mica and quartz are common minerals that play an important role in mineralogy. Although they are both silicate minerals, there are clear differences between them. First, mica and quartz are very different in appearance. One of its distinguishing features is that mica exhibits a layered structure that can be easily peeled off into thin flakes. Quartz, on the other hand, is a uniform crystal with no layered structure. Additionally, mica is usually dark in color, such as black, brown, or green, while quartz is usually clear or white. Secondly, mica and quartz also differ in their physical and chemical properties. The hardness of mica is usually between 2.5 and 4, which is relatively easy to be scratched; while the hardness of quartz is very high, 7, which is a very hard mineral. In addition, mica has good refractive properties and electrical properties, while quartz is an excellent piezoelectric material.
