1. Mining and Quarrying

Mataki na farko a cikin aikin sarrafa yashi na silica shine cire kayan aiki daga ma'adinai ko wurin yin dutse. Ajiyar yashi na silica za a iya samu a cikin ƙasa da kuma a ƙasar. Ajiyoyin da ke a cikin ƙasa yawanci ana yin su ta hanyar hanyoyin yin ma'adinai na buɗe rami. A wannan tsari, kayan aiki masu girma na motsa ƙasa kamar su excavators da loaders ana amfani dasu don cire overburden, wanda shine layer na so

Hanyoyin fitar da ƙarfe na silika, a gefe guda, yawanci suna amfani da jiragen ruwa masu daukar abu. Wadannan jiragen ruwa an shirya su da naushi da bututu masu tsawo wadanda za su iya isa ƙasa domin cire ƙarfe na silika. An dauki ƙarfen silika da aka cire zuwa wuraren sarrafawa da ke kan ƙasa ta amfani da jiragen ruwa ko bututun ruwa.

2. Tafasa

A gabanin zaɓin, ƙarfe na silika da ba a sarrafa ba yawanci yana da manyan duwatsu ko duwatsu da ake buƙata a rage girmansu. Aikin rushewa yana da mahimmanci don rushe waɗannan kayayyakin da ba a dace ba zuwa ƙananan ƙwayoyin da za a iya sarrafa su.

2.1 Tsarin Tafasa na Farko

Don rage ƙaramin yawan ƙarfe na ƙarfe na silica na farko, ana amfani da manyan injinan tafasa a cikin ayyukan tafasa na farko.

Aiki: Tafasa ma'adanin da ba a sarrafa ba (≤1m) zuwa 50-100mm.

Fa'ida:

• Tsari mai sauƙi, ƙarfin sarrafawa mai yawa, dacewa da kayan ƙarfi.
• Ana yin takardar tafasa daga ƙarfe mai yawa na manganese ko kayan juriya masu juriya don ƙara rayuwarsa.

Misalan halitta: jerin PE (kamar PE600×900), jerin C6X na injinan tafasa (kamar C6X180).

2.2 Tafasa na biyu da na uku

Bayan rushewar farko, rushewar na biyu da na uku na iya zama dole don rage girman ƙwayoyin zuwa kewayon da ake so don raba su. Masu rushewa na Cone na iya samar da girman ƙwayoyin da suka fi dacewa kuma suna dacewa da sarrafa kayan matsakaici zuwa masu wuya kamar yashi na silica.

Aiki: suna rushe kayan 50-100mm zuwa 10-30mm, suna samar da girman ƙwayoyin da suka dace da karyewa.

Fa'ida:

• Karfin juriya na tsoka: Rarrashin dakin rushewa an yi shi da haɗin chromium mai yawa ko tungsten carbide, wanda ya dace da matakin haɗin quartz.
• Uniform particle size: laminated crushing principle, reducing over-crushing and improving the yield rate.
• Energy saving and high efficiency: Compared with impact crusher, cone crusher has 20%-30% lower energy consumption (lower long-term operating cost).

Common types:

• HST Single-cylinder hydraulic cone crusher: high degree of automation and easy maintenance.
• HPT Multi-cylinder hydraulic cone crusher: more precise particle size adjustment, suitable for high production capacity requirements. `
