Kalsium karbonat abot iku bahan bubuk kalsium karbonat sing diasilake kanthi cara ngremuk mekanik nggunakake kalsit, kapur, marmer, lan bijih liyane minangka bahan mentah. Iki nduweni ciri sumber bahan mentah sing akeh, keputihan sing dhuwur, nilai penyerapan lenga sing sithik, aplikasi sing apik, lan rega sing murah. Saiki iki minangka produk bubuk mineral anorganik non-logam sing paling akeh digunakake kanthi konsumsi paling gedhe.

Saiki, teknologi pangolahan alus kalsium karbonat abot utamane fokus ing panggilingan lan modifikasi permukaan kanggo ngolah produk sing nyukupi syarat kehalusan ing macem-macem bidang aplikasi, kalebu bubuk alus, bubuk ultrahalus, bubuk modifikasi permukaan (aktif) lan bubur kertas kalebu sawetara kategori lan luwih saka sepuluh jinis produk kalsium karbonat abot khusus kanthi kehalusan lan modifikasi permukaan lan aktivasi sing beda-beda. Dadi peralatan apa sing ngolah bubuk kalsium karbonat?Mesin HCM minangka produsen mesin lan peralatan pangolahan bubuk kalsium sing misuwur ing industri kasebut. Dina iki kita bakal ngenalake sampeyan menyang mesin lan peralatan pangolahan bubuk kalsium kanthi rinci.

Panjelasan rinci babagan mesin lan peralatan pangolahan bubuk kalsium:

Kalsium karbonat abot biasa kanthi d97≥5μm utamane diprodhuksi kanthi metode garing. Peralatan kasebut kalebu pabrik Raymond sing wis ditingkatake (pabrik rol gantung utawa pabrik pendulum), pabrik rol (kalebu pabrik rol tekanan/pabrik vertikal, pabrik rol cincin, lan liya-liyane) lan pabrik bal, lan liya-liyane.

Kalsium karbonat abot ultrahalus kanthi d97≥5μm umume nggunakake proses produksi garing, lan sawetara nggunakake proses panggilingan teles + pangatusan. Produksi garing utamane nggunakake drum ball mill + pengklasifikasi, roller mill (kalebu ring roller mill kanthi klasifikasi in-band, vertikal mill/pressure roller mill), dry mixing mill + pengklasifikasi, lan liya-liyane.

Bubur kalsium karbonat abot ultra-halus kelas lapisan kertas kanthi d97≤5μm, utamane d90≤2μm, umume diprodhuksi kanthi metode teles, lan peralatan utama yaiku pabrik pengaduk lan pabrik pasir.

Lini produksi ball mill + classifier utamane digunakake kanggo ngasilake bubuk halus kalsium karbonat abot lan bubuk ultrahalus kanthi d97=5 ~ 43μm. Iki ditondoi kanthi produksi sirkuit tertutup terus-terusan, klasifikasi multi-tahap, beban siklus gedhe (300% ~ 500%), lan kapasitas produksi mesin tunggal sing gedhe. Lini produksi iki wis digunakake wiwit pertengahan nganti pungkasan taun 1990-an lan minangka salah sawijining teknologi produksi utama kanggo lini produksi kalsium karbonat abot ultrahalus skala gedhe ing donya saiki.

Mesin giling rol cincin minangka peralatan giling alus lan giling ultra-halus sing paling akeh digunakake ing bidang kalsium karbonat abot ing China sajrone sepuluh taun kepungkur. Mesin iki nduweni rasio penghancuran sing gedhe lan konsumsi energi sing sithik saben unit produk. Pengklasifikasi alus internal utawa eksternal bisa ngasilake produk ultra-halus kanthi d97≤10μm. Kehalusan produk bisa diatur antarane d97=5~40μm; kisaran ukuran partikel produk sing paling cocog yaiku d97=10~30μm.

Roller mill (roller mill vertikal/roller mill) minangka salah sawijining peralatan skala gedhe utama kanggo nggiling alus lan nggiling ultra-halus kalsium karbonat abot. Iki ditondoi kanthi rasio penghancuran sing gedhe. Kisaran ukuran partikel produk sing paling cocog yaiku d97=15~45μm. Sawise dipasang pengklasifikasi alus eksternal, bisa ngasilake produk ultra-halus kanthi d97≤10μm. Produk kasebut nduweni bentuk partikel sing apik lan nilai penyerapan lenga sing kurang, sing cocog banget kanggo produksi. Bahan komposit berbasis poliester tak jenuh (watu buatan) nggunakake pengisi kalsium karbonat abot, lan nduweni konsumsi energi lan keausan sing sithik saben unit produk.

Teknologi panggilingan ultrahalus teles utamane digunakake kanggo ngasilake produk lapisan kertas (slurry) kanthi kelas d90≤2μm lan d97≤2μm, lan kalsium karbonat abot ultrahalus kanthi d60≤2μm (digunakake minangka pengisi plastik sawise garing). Umume, siji utawa rong tahapan proses panggilingan ultrahalus terus-terusan digunakake. Iki utamane kasusun saka gilingan campuran teles utawa gilingan pasir lan tangki panyimpenan lan pompa sing cocog.

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.
