We undertake cement plants project at an
affordable price to all our customers worldwide. All our manufactured
cement making machines including vertical shaft kiln and clinker
grinding unit are functionally and mechanically superior then the
ordinary cement plants. Our mini cement plants are :
VRRK:- Latest
Technology in Mini Cement Plant :- Capacity ( 30 TPD TO 300 TPD )
Raw Materials :
- Limestone (purity not less than 88% Total Carbonate)
- Clay ( Black Soil ) should be buttery
- Coke Breeze / Petro Coke
- Laterite ( Used if Clay do not have 16% Fe2O3)
- Gypsum (Additive used during Clinker Grinding)
Manufacturing Process
VSK Technology is used
to manufacture clinker on small scale. The plant is small and easy to
operate. The Raw Materials :
The process is divided in 3
parts:
- Raw Mill Section
- kiln Section
- Clinker Grinding Section
1. Raw Mill Section :
All the raw materials should be of less than 25 mm size. If the size of
the raw material is bigger than 25 mm, It has to be crushed through a
crusher and Hammer Mill. All the materials are crushed stored in the
storage yards through belt conveyors.
Now, the raw materials are taken as per their required percentage with
the help of a weigh belts( Control by PLC ).The measured materials is
went to feed belt conveyor and after that shifted to a feed hopper
through elevator .The feed of material is controlled with the help if
ratchet Feeder/Table feeder.
2. kiln Section :
From Surge silo the mixed raw materials are taken to Nodulizer with the
help of a screw conveyor.Then water is sprayed on the mix (10%) to make
nodules with the help of nodulizer. These nodules are fed into the kiln
through feed chute for burning and Fusion. The temperature goes up to
1350OC in the burning zone. The material travels very slowly in the
kiln. All the material get fused here. After passing through the burning
zone the material starts cooling slowly. The Clinkerisation starts and
the clinker finally comes out of the kiln.
3. Clinker Grinding Section :
The clinker so obtained is crushed to make its size less than 25 mm.
The crushers/Roller crusher are used to crush the clinker. The Gypsum is
used as an additive. Both material crushed together and went into feed
hoppers through elevator. They are collected through the feeders
provided below the feed hoppers. The clinker and gypsum are mixed in
certain ratios (5%). So, the weigh belt is used to weigh the ingredients
for mixing. A modern electronic weighing & control system may also
be used to weigh and measure the ingredients The ratchet/Tables feeder
is used to control the feed in the mill and control the fineness of the
Cement.
The ground Cement is taken to the aeration and storage silo with the
help of elevator or air lift.The aerated Cement is filled in 50Kg bags
with the help of packing machine. The product is stored in the godown
through belt conveyor and stacking/dispatched as per requirements. The
pollution control equipments are necessary as there may be dusting in
the plant.
