Peralatan Penghancur Batu Kapur dan Lini Produksi

Batu kapur is one of the most widely distributed rocks in nature. Its main component is calcium carbonate (CaCO₃), which gives limestone a wide range of applications in construction, agriculture, and industrial production.

Limestone can be directly processed into aggregates and building materials using crushing equipment. It can also be calcined to produce quicklime (calcium oxide, CaO). When quicklime reacts with water, it produces hydrated lime (calcium hydroxide, Ca(OH)₂), which can then be processed into lime slurry, lime paste, and other products used as coating materials, binders, and brick adhesives.

With the growing demand for limestone aggregates and manufactured sand, efficient limestone crushing equipment and complete crushing production lines are becoming increasingly important. So, what equipment is suitable for crushing limestone, and how should you configure a limestone crushing plant?

 

 

Penggunaan Batu Kapur

Batu kapur adalah batuan serbaguna dengan berbagai kegunaan:

• Bahan Konstruksi: Batu kapur adalah bahan yang populer digunakan untuk membangun gedung, jalan, dan jembatan. Batu kapur sering dipotong menjadi balok atau lempengan untuk keperluan ini.
• Sumber Kalsium: Batu kapur adalah sumber kalsium yang signifikan, digunakan dalam produksi semen dan mortar serta sebagai pembenah tanah di bidang pertanian.
• Agen Penetralisasi: Batu kapur yang dihancurkan digunakan untuk menetralkan tanah asam, membantu meningkatkan kesuburan tanah untuk pertanian.
• Penggunaan Industri: Limestone is used in various industrial processes. It can be a raw material in producing lime (calcium oxide) and is used in manufacturing steel, glass, and other materials.
• Batu Hias: Batu kapur juga digunakan untuk tujuan dekoratif dalam lansekap dan arsitektur. Batu kapur dapat dipoles untuk mendapatkan permukaan yang halus atau dibiarkan dalam kondisi alami untuk tampilan yang lebih kasar.
• Pengolahan Air: Batu kapur digunakan dalam proses pengolahan air untuk menyesuaikan tingkat pH dan menghilangkan kotoran dari air.
• Gua dan Lanskap Karst: Banyak gua dan lanskap karst yang terbentuk di daerah batu kapur melalui pelarutan batuan oleh air.

Limestone occurs in a variety of colors, including white, gray, yellow, brown, and black. Its composition, hardness, abrasiveness, and other physical properties can vary depending on its geological origin and impurities. These differences can affect the selection of peralatan penghancur and the final application of the processed limestone.

 

Peralatan Penghancur Batu Kapur

Berdasarkan karakteristik batu kapur, berikut adalah beberapa mesin yang direkomendasikan untuk Anda: jaw crusher, impact crusher, penyaringan, pengumpanan, dan peralatan pendukung lainnya.

Penghancuran primer - penghancur rahang

Batu kapur berukuran besar perlu diangkut ke dalam penghancur rahang by the feeder for preliminary crushing, and the crushed materials will be transported to the next stage.

Penghancuran sekunder - penghancur tumbukan

Konveyor mengirimkan batu kapur yang dihancurkan secara kasar ke penghancur benturan untuk penghancuran lebih lanjut. Penghancur tumbukan memiliki ketahanan aus yang baik, ukuran partikel pembuangan yang baik, bahan halus yang rendah, dan kandungan serbuk batu yang rendah.

Penyaringan - layar bergetar

Setelah tumbukan, material batu yang dihancurkan dengan halus masuk ke dalam layar bergetar untuk menyaring spesifikasi batu yang memenuhi kebutuhan produksi.

Kembalikan bahan untuk dihancurkan 

Batu kapur yang tidak memenuhi spesifikasi yang disaring oleh mesin penyaring harus dikembalikan ke mesin penghancur untuk dihancurkan lagi sampai memenuhi persyaratan spesifikasi produk jadi.

 

 

Lini Produksi Penghancuran Batu Kapur

A typical limestone crushing production line consists of a vibrating feeder, jaw crusher, impact crusher, vibrating screen, belt conveyors, and an electrical control system.

Depending on the raw material characteristics and final product requirements, additional equipment such as a cone crusher, vertical shaft impact crusher, sand washing machine, and dust collection system can be added.

The jaw crusher performs coarse crushing of sand and gravel, and the feeding force is large. The impact crusher finely crushes the sand and gravel, with a small size and low energy consumption. The penghancur kerucut performs fine crushing of high-hardness materials, with a strong crushing force and high safety factor. Sand-making machine processing capacity: strong, uniform grain shape.

A common limestone crushing process is:

Limestone → Vibrating Feeder → Jaw Crusher → Impact Crusher → Vibrating Screen → Finished Aggregates

Oversized material from the vibrating screen can be returned to the impact crusher for further crushing, forming a closed-circuit crushing system.

If manufactured sand is required, a sand-making stage can be added:

Limestone → Vibrating Feeder → Jaw Crusher → Impact Crusher → Sand-Making Machine → Vibrating Screen → Sand Washing Machine → Finished Sand

The specific configuration should be selected according to the raw material properties, production capacity, feed size, finished product size, and investment budget.

 

 

Main Stages of a Limestone Crushing Plant

Feeding Stage

Pengumpan bergetaryang dapat memasukkan material ke dalam crusher secara merata, kuantitatif, dan kontinu, biasanya digunakan.

Crushing Stage

The process involves several crushers, mainly coarse crushing, and medium and fine crushing equipment. Jaw crushers are mainly used for coarse crushing, and cone crushers and impact crushers are mainly used for medium and fine crushing. They can process hard rocks, such as granite, and soft rocks, such as limestone.

Sand-making Stage

The sand-making stage is generally used after the crushing stage. A vertical shaft impact crusher is commonly used, which can further crush and shape the stones produced by the crushing process to produce machine-made sand specifications of less than 5mm.

Screening Stage

Operasi penyaringan adalah proses tambahan. Bahan pasir dan kerikil yang sudah jadi dari proses penghancuran atau pembuatan pasir disaring melalui layar getar untuk mendapatkan spesifikasi dan gradasi produk jadi.

Conveying Stage

Pengangkutan dan penyaringan juga merupakan proses tambahan. A konveyor sabuk adalah peralatan pengangkutan kontinu yang ideal dan efisien dengan pengangkutan kontinu, keandalan, kenyamanan, jarak pengangkutan yang jauh, konsumsi energi yang rendah, kapasitas pengangkutan yang besar, serta perlindungan hijau dan lingkungan.

Sand Washing and Dust Removal Stage

Peralatan penghilang debu dan peralatan pencuci pasir umumnya dikonfigurasikan sesuai kebutuhan. Di bawah persyaratan perlindungan lingkungan, polusi debu diminimalkan. Mesin cuci pasir umumnya dilengkapi dengan mesin cuci pasir roda dengan output tinggi, pengoperasian sederhana, dan pengoperasian yang mudah.
