Ceramic Sand Granulator Introduction:
According to the experience of the ceramsite industry and the
exploration and analysis of research institutions, in order to fire
qualified ceramsite, there are certain requirements for its
composition before firing. Therefore, after analyzing the
composition of the main raw material of ceramsite, it is necessary
to add some auxiliary materials to make It meets the requirements.
Taking the raw material preparation of Chongqing Yongchuan Project
as an example, it uses two materials, namely sludge and shale.
Through the preliminary treatment of the raw materials, the two raw
materials must be measured and proportioned. The process flow is:
the sludge is sent to the sludge tank for storage, and the sludge
is sent to the sludge receiving hopper through the grab crane and
subjected to the hopper and screw conveyor. After the
weightlessness scale is measured, it is sent to the double-shaft
mixer by another screw conveyor; the shale powder is measured by
the screw weighing scale under the powder bin, and is also sent to
the double-shaft mixer through the scraper conveyor. After the two
materials are evenly mixed in the double-shaft mixer, they enter
the aging bin through the belt conveyor for aging for 7-15 days.
The aged materials are taken out by the reclaimer and sent to the
granulation section through the belt conveyor.
In this process, two aspects need to be considered at the same
time. One is that the composition of the two raw materials meets
the requirements, and the other is that the moisture meets the
requirements. The composition requirement takes precedence over the
moisture requirement. Through the preliminary analysis of
ingredients, the ratio of sludge and shale is determined. After the
two are measured, they are stirred evenly and sent to the aging
warehouse. The aging process is also called the homogenization
process, and the purpose is to pass the raw materials A series of
physical and chemical reactions between the two to achieve the
refinement and mixing of the raw materials in the microscopic
field, so that the composition of the mixture before entering the
kiln is uniform and stable, and can stabilize the working
conditions of the kiln.
Ceramic Sand GranulatorAdvantages:
It is mainly used for production of oil fracturing proppant
(ceramic sand), and also be applied for balling powder, granular,
small lump material such as coal powder, limestone, coal, clay and
etc.
1. The whole process of granulation is inside the fully enclosed
drum, and the drum interior is at slightly negative pressure state.
It is without dust pollution, clean and environmental friendly.
2. Feed - mixing - nucleation - granulators - shaping,the whole
process is controlled by computer through PLC. It is easy operation
and high degree of automation;
3. After abrasion treatment, the rotor surface had made precise
balancing to ensure movement stability, reliability and wear
resistance under high rotational speed. So that the machine can
work stable and reliable;
4. The scraper surface has had appropriate wear treatment. The
bottom and the inside of the drum is equipped with wear-resistant
liner, therefore, the entire drum parts have a long service life.
