Sand and gravel production line equipment--Sand production line

Sand also called artificial sand, the rock by the addition of soil mining, mechanical crushing, screening made, the nominal particle size of less than 5mm rock particles. Sand production line according to legal process is divided into wet sand and dry sand two kinds of legal process.
Dry Process sand process advantages:
1. fineness modulus and gradation zone adjustment: Sand, gravel powder separation unit is equipped with variable speed control system that can adjust according to the characteristics of raw materials, production patterns, to achieve quick and easy adjustment mechanism fineness modulus of sand and dust content , is the most advanced production technology.
2. Dust content (sand equivalent) Adjustments: sand powder separator through the dust content adjusted to the range of application requirements.
3. good environmental performance: with a special dust removal system, dust a small, run-time noise is less than 90dB.
4 .small footprint, production line layout is compact, high degree of automation: plane occupies 35 meters × 20 meters, the production run only two workers per shift. Wet sand mountains of legal process, the use of new sand making equipment to replace rod mill higher operating costs, greatly improve the reliability of artificial sand production run, to ensure product quality.
Major equipment:
Feeder, crushing with jaw crusher, cone crusher used in crushing or impact crusher, vibrating screen, crusher and sand and gravel washing equipment sand washing machine. Sand production line according to different hardness and size of the stone In sand production should adopt appropriate crushing sand making equipment, sand production line in order to ensure stable operation, smooth.
Process description:
Stone consists of vibrating feeder evenly sent to jaw crusher for coarse broken, coarse material after breaking from the belt conveyor fed into the crusher for further crushing, crushing the material after being transported to the vibrating sieve, meet the size requirements of the finished material is fed into the sand washing machine cleaning, after cleaning the finished product conveyor output is finished; does not meet the size requirements of finished material from the vibrating screen returns Sand reworked to form a closed loop several times. Finished size according to the needs of users to mix and graded. If I choose to dry production process, can be equipped with the thickness powder separator and dust removal equipment.
Applications:
Quartz ore is mainly used for the manufacture of quartz powder etc. roughing. Quartz mine since high hardness, processing generally using impact crusher (sand making machine). Sand can be used for soft or hard and extremely hard materials crushing, plastic, over used in various ores, cement, refractories, construction, water conservancy, metallurgy and other industries.
Performance:
The sand production line high degree of automation, low running costs, crushing rate, energy saving, large output, less pollution, easy maintenance, to produce sand meet national building sand standard, uniform particle size, grain shape is good, with reasonable level. The  sand making equipment  is mainly based on customer specifications and production of stone and stone uses to determine, we provide pre-sale, sale and comprehensive services, based on customer production site to the configuration process, and strive to provide our customers the most reasonable, the most economical production line.
Rust Method:
Rust first one: chemical rust. Contacting a metal oxide with an acid solution is prone to chemical reaction. We can use this to rust. Of course, there are professional pickling plant even more convenient. There is a strong corrosive acid solution, please pay attention to safety.
Rust second measure: high pressure water blasting. Stienclled using high pressure water equipment. This approach is characterized by rust trick no dust pollution, no harm, but also improves the efficiency. But after the return of steel rust rust belt, coating paint, wet performance is greatly affected rust paint.
Rust third measure: Compressed air blasting. Compressed air and install the appropriate descaling device, reciprocating or rotary, in order to meet the different needs of rust. If the angle grinder, wire brush, pneumatic needle beam, pneumatic knock rust rusty, can rust, paint fight hair treatment efficiency than manual rust greatly improved, up to 1 ~ 2m2 / h, but not descaling the surface roughness is small, can be achieved [1] high-quality, high efficiency and the jet surface. Can be used in any position, particularly in the repair process has been widely used.
Broken equipment, high chromium cast iron hammer life is largely related to the quality and castings, while casting process have a great impact on their quality, using reasonable casting process can reduce or even avoid many casting defects generated especially sand production line equipment cracks to appear. To this end, for cast iron alloy content, good fluidity, shrink large, poor thermal conductivity characteristics, therefore should be taken in the casting process on the use of 2% shrinkage manufacturing appearance.
Sand production line in which the jaw crusher rotates, working resistance power and drive power for most jaw crusher can not remain equal at any instant; when the power is greater than the resistance reactive power, the spindle speed increases; otherwise reduced. At this rate fluctuations will affect the production process, causing the elastic vibration, more power consumption and reduce mechanical efficiency, and even affect component strength. Therefore, the resistance showed a cycle of pieces of work or aperiodic variation of sand production line, dryer manufacturers to solve the speed problem.
