LVJOE MACHINERY
MANUFACTURING
There is a power that can be
ground-breaking!
There is persistence that can be
persistent forever!
The name LVJOE might not be
familiar to you, but it leads the development of this
industry.
You may feel the name LVJOE
amiable, because it will build wonderful future. Today’s LVJOE has
won the world with its honesty. Tomorrow’s LVJOE will continue to
lead Chinese gypsum industry and create an innovative
precedent.
The theme of human developments
is building a resource-conserving and environmental friendly
society. Today, low-carbon and cyclic economy has become the
orientation of society development and will be further more the
goal that modern construction industry should
pursue.
The application of the
ecological and energy-efficient wall materials has become the
development tendency in modern construction. Gypsum, with its
unique texture and advantages, is now replacing traditional
building materials and gradually will become the main trend of
eco-energy saving wall.
Hebei LVJOE machinery
manufacturing co., ltd. was established in ***8 with the increasing
market demand and the national policies on new wall reform. LVJOE
now has more than **0 staff, *0 processing equipments, several CNC
equipments. We have won a number of honors including ISO***1:***0
Quality management System Certification. LVJOE grows rapidly into
one of leading manufacturers of new gypsum walling materials by its
unique design, manufacture and production technology. We integrate
production with institute high-tech research and are professional
in machinery design & manufacturing enterprise. We have a
R&D team with experts, senior engineer and professor as key
backbone.
Its production scale, technology
level, product quality and processing means stand in top class of
this industry. Paper faced gypsum board production lines have
similar process flow. According to heating methods, there are two
types: direct hot air type and indirect heat exchanging
type. Clean fuel has to be used in direct hot air type, like
Nature Gas or Light diesel. Indirect heat exchanging type takes
coal or heavy oil as fuels. The heat efficiency is low compared
with direct hot air type because hot air is used after exchanging.
But this type is suitable for some countries where no natural gas
or light diesel. The main equipments of paper faced gypsum board
production line include: batching system, forming system, wet board
conveying system, drying system, dry board conveying, board edge
trimming, stacking and storage system. The electrical control of
gypsum board line is divided into 3 parts, forming station control,
drying control and dry board control. The process flow of paper
faced gypsum board: calcined gypsum powder is conveyed into plaster
powder silo. Other raw materials like modified starch, accelerating
agent, etc. which are also stored in silos. Weighing belt is
installed at the bottom of the silo. Various materials will be put
together into powder mixer after dosing process, and then fed into
vertical mixer. Foaming agent and water through metering pump are
sent to foaming device where they meet compressed air to produce
foam which is then brought to vertical mixer. Top & Bottom
cover paper pass through tensioning device, alignment device,
creasing device to forming station. Gypsum slurry flows on the
surface of bottom paper from vertical mixer. Adhesive glue, mixed
in tank, is delivered to spray glue pump which locates at two sides
of forming station. Then it is sprayed on the edges of top paper by
the spray glue pump. Forming station adopts advanced plate forming
machine or extruder, which changes the contact from linear to
area.
And thickness adjustable,
extruded gypsum board surface has better smooth appearance. Wet
board is steady conveyed to cutting machine through setting belt
and open roller conveyer. Continuous board is cut into pieces at
set length by cutting machine and then be transported to transverse
conveyor 1#. After overturning, wet boards are then sent into
roller drier after passing through closer roller conveyor and
distributing bridge. The free water in the wet boards will
evaporate slowly and boards are cooled down after drying at board
outlet section. Then dried boards pass through in consequence
transverse conveyor 2#, folding machine, rolling table and edge
trimming machine where to be cut at exact dimension and sealed by
edge wrapping afterwards. Finished boards pass roller conveyor to
stacker. Then they are moved to ware house by forklift, ready to
packaging.
The main raw materials of Gypsum
block usually is of nature gypsum and chemical gypsum such as
desulfurization gypsum (or FGD) and phosphorous gypsum. After being
mixed with water and casted in moulds, lightweight building gypsum
block product is produced. The whole production process is safe and
clean, producing no waste gas, liquid and solid residues. The
advantages of gypsum block are of low product cost, high investment
return and market competitiveness.
And large scale production
consumes large quantity of chemical gypsum, which is a most
effective way to solve the problem of chemical gypsum recycling.
Gypsum block production line is made of hydraulic ejection molding
machine, screw feeder, high-speed mixer, and pneumatic clamping
tools. Block production line adopts vertical mold pouring, jack
lifting and multi-cavity mold technology for increasing production
capacity of a single machine. The output is improved significantly
by retracting pneumatic clamps to correct positioning of clamping,
lifting up and moving the whole row of gypsum blocks. The quality
of surface is improved remarkable by using hydraulic automatic
scraping that makes the upper tongue-and-groove and chroming alloy
die.
Gypsum block production line is
an ideal investment project, with low investment and short finance
return period.
For years, LVJOE has been
dedicating to building strong brand of Chinese machinery and
electronics, realizing great dream of enriching customers by
science and technology and serving the country by industry. On our
way forward, we never stop, constant innovation, constant beyond
and constant development bring new hope for Hebei LVJOE Machinery
Manufacturing Co., Ltd.
LVJOE will further speed up the
pace with the quickening process of international economic
integration. “Being responsible for customers, ensuring quality of
products and abiding by the credit “is fundamental principle of our
company. We insist on it as our business principle.
We will build top brand by fully
developing our advantage, completing market distributional channel
and improving network service. We are confident to obtain greater
success by virtue of service and technology in
future.
LVJOE Company is sincerely
willing to cooperate with all friends of the whole world, to create
a brighter future together.
