Raw meal masuk ke silo untuk menjalani proses selanjutnya yaitu blending (pencampuran) sehingga alatnya dikenal dengan blending silo. Produk blending ini akan menjadi kiln feed. Kiln feed sendiri tidak hanya bersumber dari raw meal (produk raw mill) tetapi juga dari return dust yang tertangkap di EP raw mill dan dust yang terpisah di GCT .

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. It's mainly used in grinding raw materials and end products in cement plant. Raw mill is made up of feeder part,discharging part,rotating part,transmission part (reducer,samll transmission gear,motor,electric control) etc.

Inverted Cone Blending Silo. The blending silo is simultaneously used for a continuous blending process as well as for raw mix storage. The feeding of the silo takes place via a parallel distributor and aero-slides ensuring a controlled build-up of the different material layers. Homogenizing of the raw meal is achieved by causing the layers of ...

Pre-Blending and Raw mill Stage. Limestone from mines are brought to plant site and stored in the yard then fed to dump hopper of primary crusher by mixing high-grade and low-grade limestone in defined proportion to meet the quality norms. The primary crusher is designed with 350 TPH and secondary crusher is installed to reduce the limestone ...

pengeringan sehingga diperoleh produk raw mill dengan kehalusan ayakan 90 mikron dan kandungan air kurang dari 1%. Dari raw mill, tepung baku dimasukkan kedalam blending silo. Fungsi dari blending silo adalah untuk menghomogenkan produk raw mill agar komposisi kimia dari produk tersebut selalu tetap sehinggga siap untuk diumpankan ke rotary kiln.

Silo Design Best Practices 1: Homogenizing and Blending Silos. The production of cement with reliable characteristics requires consistency. Throughout the years, preparation and storage of the blend of materials used to produce clinker has evolved. This includes the production of the raw material, storage, and transport to the kiln.

Bahan baku masuk ke dalam Vertical Roller Mill (Raw Mill) pada bagian tengah (tempat penggilingan), sementara itu udara panas masuk ke dalam bagian bawahnya. Material yang sudah tergiling halus akan terbawa udara panas keluar raw mill melalui bagian atas alat tersebut. Material akan digiling dari ukuran masuk sekitar 7,5 cm menjadi max 90μm.

Blending Factor For calculation of blending factor of a silo, input and output raw meal samples are to be collected in regular intervals and to be tested for CaCO3 content. Silo input samples to be collected for a period of one theoretical filling of silo with an interval not exceeding 1.5 hours and a minimum 40 samples are to be collected.

raw meal for the production of cement clinker. This situation calls for the use of integrated mixture control concepts starting in the quarry control the blending bed stacking and assure minimum standard deviation of the lime standard and other moduli upstream of the mill and in the material taken from the corrective material silos.

The functions of a new multi-cell silo, developed by Polysius, for reliable blending and storage of difficult raw materials are discussed. The filter dust from the mill bypass operation can be ...

Raw Mill. These raw materials are fed in a predetermined proportion into the raw mill for grinding. The finely ground raw meal is conveyed to the blending and storage silo where through blending of this meal is done by aeration. The raw meal from the silo is conveyed to the rotary kiln through preheater tower.
