Ieu ngagaduhan ciri sumber bahan baku anu lega, bodas anu luhur, nilai serapan minyak anu handap, aplikasi anu saé sareng harga anu murah. Ayeuna ieu mangrupikeun produk bubuk mineral anorganik non-logam anu paling seueur dianggo kalayan konsumsi panggedéna.

Ayeuna, téknologi pamrosésan halus kalsium karbonat beurat utamina museur kana ngagiling sareng modifikasi permukaan pikeun ngolah produk anu nyumponan sarat kehalusan tina rupa-rupa widang aplikasi, kalebet bubuk halus, bubuk ultrahalus, bubuk modifikasi permukaan (aktif) sareng bubur pembuatan kertas ngawengku sababaraha kategori sareng langkung ti sapuluh jinis produk kalsium karbonat beurat khusus kalayan kehalusan sareng modifikasi permukaan anu béda-béda sareng aktivasina. Janten alat naon anu ngolah bubuk kalsium karbonat?Mesin HCM nyaéta produsén mesin sareng peralatan pangolahan bubuk kalsium anu kasohor di industri ieu. Dinten ieu kami bakal ngenalkeun anjeun kana mesin sareng peralatan pangolahan bubuk kalsium sacara rinci.

Katerangan lengkep ngeunaan mesin sareng peralatan pangolahan bubuk kalsium:

Kalsium karbonat beurat biasa kalayan d97≥5μm utamina dihasilkeun ku metode garing. Peralatanna kalebet Raymond mill anu ditingkatkeun (hanging roller mill atanapi pendulum mill), roller mill (kalebet pressure roller mill/vertical mill, ring roller mill, jsb.) sareng ball mill, jsb.

Kalsium karbonat beurat ultrahalus kalayan d97≥5μm umumna nganut prosés produksi garing, sareng aya anu nganggo prosés panggilingan baseuh + pangeringan. Produksi garing utamina nganggo drum ball mill + classifier, roller mill (kalebet ring roller mill kalayan klasifikasi in-band, vertical mill/pressure roller mill), dry mixing mill + classifier, jsb.

Bubur kalsium karbonat beurat ultra-halus kelas palapis kertas kalayan d97≤5μm, khususna d90≤2μm, umumna dihasilkeun ku metode baseuh, sareng alat utama nyaéta gilingan aduk sareng gilingan keusik.

Jalur produksi ball mill + classifier utamina dianggo pikeun ngahasilkeun bubuk halus kalsium karbonat beurat sareng bubuk ultrafine kalayan d97=5 ~ 43μm. Ieu dicirikeun ku produksi sirkuit tertutup kontinyu, klasifikasi multi-tahap, beban siklus ageung (300% ~ 500%), sareng kapasitas produksi mesin tunggal anu ageung. Jalur produksi ieu parantos dianggo ti saprak pertengahan dugi ka akhir taun 1990-an sareng mangrupikeun salah sahiji téknologi produksi utama pikeun jalur produksi kalsium karbonat beurat ultra-halus skala ageung di dunya ayeuna.

Panggilingan rol cincin mangrupikeun alat panggilingan halus sareng panggilingan ultra-halus anu paling seueur dianggo dina widang kalsium karbonat beurat di Cina dina sapuluh taun ka pengker. Ieu dicirikeun ku rasio penghancuran anu ageung sareng konsumsi énergi per unit produk anu handap. Klasifikasi halus internal atanapi éksternal tiasa ngahasilkeun produk ultra-halus kalayan d97≤10μm. Kehalusan produk tiasa disaluyukeun antara d97=5~40μm; rentang ukuran partikel produk anu paling cocog nyaéta d97=10~30μm.

Roller mill (vertical roller mill/roller mill) nyaéta salah sahiji parabot skala ageung utama pikeun ngagiling halus sareng ngagiling ultra-halus kalsium karbonat beurat. Ieu dicirikeun ku babandingan penghancuran anu ageung. Rentang ukuran partikel produk anu paling cocog nyaéta d97=15~45μm. Saatos dipasang klasifikasi halus éksternal, éta tiasa ngahasilkeun produk ultra-halus kalayan d97≤10μm. Produk ieu ngagaduhan bentuk partikel anu saé sareng nilai panyerepan minyak anu handap, anu khususna cocog pikeun produksi. Bahan komposit berbasis poliéster tak jenuh (batu jieunan) nganggo pangisi kalsium karbonat beurat, sareng ngagaduhan konsumsi énergi sareng keausan per unit produk anu handap.

Téhnologi panggilingan ultra-halus baseuh utamana dianggo pikeun ngahasilkeun produk palapis kertas (slurry) kelas d90≤2μm sareng d97≤2μm, sareng kalsium karbonat beurat ultra-halus kalayan d60≤2μm (dianggo salaku pangisi plastik saatos dikeringkeun). Sacara umum, hiji atanapi dua tahapan prosés panggilingan ultra-halus kontinyu dianggo. Ieu utamina diwangun ku panggilingan campuran baseuh atanapi gilingan keusik sareng tangki panyimpenan sareng pompa anu saluyu.

The production capacity of ordinary heavy calcium in the domestic market has become saturated, and the product price is low, and the technological content and added value are not high. For ultra-fine and active heavy calcium, domestic production capacity cannot meet the demand and still has great market potential. Overall, the main development trends of heavy calcium carbonate industry technology are large-scale, functional and intelligent. This is an inevitable requirement for the intensification, stabilization, structural optimization or specialization of heavy calcium carbonate production, as well as improving production efficiency, reducing energy consumption, wear and tear and reducing production costs. It is also an inevitable requirement for the development of production technology due to the significant increase in market demand and saving the amount of resin in polymer-based composite materials.It is necessary for domestic heavy calcium carbonate companies to learn from the successful experiences of world-famous calcium carbonate companies such as Omya and Imerys, and adopt high-efficiency, energy-saving large-scale equipment and advanced production technology to promote the in-depth development of my country’s heavy calcium carbonate industry in terms of scale and product refinement.As an equipment supplier recognized by Omya, HCM has provided calcium powder processing machinery and equipment to many Omya factories around the world, which are highly praised and favored by customers. If you have purchasing needs for calcium powder processing machinery and equipment, please contact us for details of the equipment. Email:hcmkt@hcmilling.com
