Vertical Raw Mill Introduction:
Vertical raw mill is widely accepted as the most efficient means of preparing most moist raw materials for the production of cement clinker. Vertical raw mill can prepare virtually any kiln feed material to your required fineness in an energy-efficient process – regardless of variations in grindability, drying requirements and abrasion. In fact, it can be adapted to a wide variety of specific requirements.

Remarks: the basic standard for vertical mill is as follow:
(1)Power consumption:slag≤25kWh/t,cement≤18kWh/t,raw meal≤9kWh/t；
(2)Moisture content:slag≤15%,cement≤3%,raw meal≤7%；
(3)Ffinished product fineness: specific surface area of slag 4200~4500cm²/g,specific surface area of cement 3300~380 cm²/g,raw meal fineness-80μmR 12~15%；
(4)Moisture content of refined powder:slag 0.5~1.0%,cement 0.5~1.0%,raw meal 0.5~1.0%；
(5)The specific installed capacity and parameters can be adjusted properly according to actual material nature.
(6)The above parameters are applicable for granular blast furnace slag, cement and raw meal and the model selection is determined by material property.
Vertical Raw Mill Working Principle:
The raw material from dosing station after weighing, transported into inlet of vertical mill by belt conveyor, then fed into rotary air lock of vertical mill with outer recycle materials, after the grinding, drying, separating, the crude material comes back grinding disc for grinding again, the qualified product will be brought into cyclone filter through separator, the product collected by cyclone filter and powder from bag filter at the kiln tail comes into raw meal homogenizing silo by air chute, bucket elevator and so on.
The part of exhaust gas from cyclone filter came back into air inlet of vertical mill, and other will be discharged into atmosphere through kiln system filter, fan and chimney.
The heat air source of raw material vertical mill is from high temperature fan and preheater exhaust gas.
Start of the Pulverized Coal Vertical Mill System:
Startup: Lubrication system (Thin oil station) motor → Separator motor (frequency conversion motor) → Roller lifting → Main motor → Feeding and falling roller → Hydraulic system motor (pressurizing).
Normal Shutdown Process of Pulverized Coal Vertical Mill System:
Shutdown: Stop material command start----Feeding operation stop----Start roll lifting operation----Vertical mill main motor stop----Oil station operation stop----Hydraulic station stop
