Emery sand: also known as silicon carbide, refractory sand, there are two common basic varieties of black silicon carbide and green silicon carbide, due to little natural content, silicon carbide is mainly artificial, and its chemical properties are stable, thermal conductivity is high, thermal expansion coefficient is small, wear resistance is good, and it has many other uses besides serving as an abrasive.
Quartz sand: a non-metal mineral, also a hard, wear-resistant, chemically stable silicate mineral, the main mineral component of which is SiO2, an important industrial mineral material, divided into common quartz sand, refined quartz sand, acid washed quartz sand, high-purity quartz sand and so on.
Currently, it is also reported to face a shortage crisis in sand, with a two-fold increase in usage, partly due to the rapid pace of urbanization, consumption far exceeding the natural increase in sand and the mechanism there is no delay in sand green development, so what is the difference between emery sand and quartz sand, and what are the two? What is the price of emery sand preparers? How should the production process be designed? See below.
1. Distinction between diamond sand and quartz sand.
01. appearance different.
Emery sand is generally yellow to green, to blue to black crystals, depending on its purity.
Quartz sand color was creamy white and colorless with translucency.
02. formation of different.
Diamond sand is produced by high-temperature smelting using quartz sand, petroleum char (coal char), wood chips (adding salt when producing green silicon carbide) and other raw materials through an electrical resistance furnace.
Quartz sand is the quartz particles from which the bulk quartz stone has been broken and processed.
03. the hardness was different.
The diamond Mohs hardness is 9.5, second only to diamond (Grade 10), has excellent thermal conductivity, is a semiconductor, and can protect against oxidation at high temperatures.
Quartz sand Mohs hardness 7, brittle without cleavage, shelllike fractures, grease gloss, density of 2.65, bulk density (1.6-1.8 for 1-20 mesh).
04. field of application.
The diamond sand mainly has four main areas of application, namely: ceramics, refractory materials, abrasive and metallurgical feedstocks.
Quartz sand is applied in glass, ceramics, chemical, etc, as well as has a pivotal position in aerospace, space, electronics, as well as in the rapidly developing IT industry.
2. Emery sand making machine equipment and production process.
Because of its high hardness and toughness, SMMVIK Machinery has developed and manufactured a diamond grinding machine according to its composition and structure, which is highly recognized and favored by users. Meanwhile, it also provides a crusher and designs production process flow on a tailor-made basis.
01. Diamond Sand Making Machine.
Feed Size: <55mm;
Capacity: 60-650t/h;
Particle size of finished product: 0.25-0.5mm (coarse, medium and fine sand), good shape and adjustable fineness modulus of finished product;
Performance characteristics: Combining with the actual situation of domestic sand production, it integrates all kinds of crushing modes, mainly adopts the working modes of "stone beating stone" and "stone beating iron". Through the design of deep chamber impeller, the quantity is increased and the working efficiency is high. Even when handling high-hardness materials, the service life of vulnerable parts is very long. The upper and lower perimeter guards can turn around, and the combined throwing head is adopted at the same time. Only the worn parts need to be replaced, which can reduce the cost of use. Hydraulic cap opener is easy to repair and maintain.
02. Emery sand manufacturing process.
Emery -> vibration feeder uniform conveying -> jaw crusher -> belt conveyor ->cone crusher -> belt conveyor -> sand making machine for fine (0.05-5mm sand) -> belt conveyor -> vibrating screen screening -> qualified material -> belt conveyor -> silo stockpiling.
Above is the process of crushing and sand making. Besides, there are also processes of charging, power transmission smelting, cooling and grading of outlet. For more details, please consult for further information.
3. What is the price of emery sand Machine?
The choose and buy a emery sand making machine price, high and low range on the market, also depends on equipment manufacturers such as the selection model, output, situation, in addition to pay attention to itself quotation, also want to inspect the quality and performance, if the price is cheap, but often buy back maintenance downtime, also not be very cost-effective.
