Expandable Pattern Casting and Plaster Mold CastingMarry Sol Lare
Expandable pattern casting and plaster mold casting are two types of expendable mold casting processes. Expandable pattern casting uses an expandable polystyrene pattern that is coated, embedded in sand in a flask, and then vaporized when molten metal is poured, leaving an exact replica of the pattern. Plaster mold casting similarly uses a plaster mold instead of sand and is best for smaller, non-ferrous metal castings due to temperature limitations of plaster. Both methods can produce complex, close-tolerance castings with minimal finishing required.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

2. Hengyang Gypsum Mining Instruction:
Gypsum (CaSO4.2H2O) is a met stable substance derived from the hydration of anhydrite, which is a primary mineral. The
essential ingredient in all the rock types is CaSO4. Hardness of gypsum is 2, specific gravity 2.32 and porosity more than
20%. The solubility of gypsum is slow. Various grades of gypsum and their uses as raw materials are as under:
High Quality Gypsum:
Gypsum (CaSo4.2H2o) containing more than85% is an essential raw material for gypsum and alpha gypsum plaster.
Gypsum plaster can only be manufactured from high grade gypsum.
Low Quality Gypsum:
50% – 85% gypsum with anhydrite and other impurities, making up the rest, is suitable for cement and agro gypsum.
Anhydrite:
Less than 50% gypsum content but essentially CaSo4. This material is suitable for cement but its suitability has to be
established for use as agro-gypsum and canal and distributaries lining as its solubility is low.
Alabaster:
An essentially CaSo4 rock that can be either gypsum or anhydrite.
Gypsum Current Usage
Gypsum / anhydrite obtained from various mines / quarries have been and / or are being used for the following industries.
AGRO-GYPSUM
In agriculture, gypsum is used as soil amender with a view to improving its chemical and physical characteristics.
Application of gypsum helps breakup hard soil, allows better aeration and water penetration and retention. The processing
of gypsum for use in the amendment of saline-sodic soils involves crushing and
Grinding rock gypsum to 30 – 40 mesh size and loose or bagged product is transported.
TREATMENT OF LOW QUALITY TUBE-WELL WATER
Many tube-wells are pumping high sodium waters that make productive land unproductive. This low quality tube-well
water retards seed germination and plant growth. In this context, gypsum boulders may be used for the patching of
distributaries and /or these sodic waters are used after passing through gypsum stored in a haudi (water tank) for the
correction of tube-well water.
CEMENT INDUSTRY
About 3% to 4% gypsum / anhydrite is used in the processing of cement for retarding its setting time. The present installed
capacity of cement plants is about20 million tons in the country. The cement production is likely to increase to 30million
tons in the next 3-5 years and subsequently gypsum consumption would increase to 3.2 million tons per annum.
PLASTER OF PARIS
Plaster of Paris is hemi-hydrated calcium sulphate (CaSo4.1/2 H2O) produced by heating of gypsum to a temperature of
between 120℃to 160℃. Plants of varying capacities (2-10 t/day installed capacities) are being used for its production.
Plaster of Paris so produced is of mediocre quality used in ceramics, paints, ornamental ceiling tiles etc.
3. Gypsum Mining Process:
Gypsum is extracted from open air or underground mines, using specific drilling machinery and non-polluting explosives.
Rock size may reach up to 50 cm in diameter.
Crushing
Primary crushing aimed at reducing rocks to a size of less than 10cm, subsequently easier to handle, is carried out in the
quarry or at the entrance to the plaster manufacturing station. Mainly Use Crusher for crushing into small sizes and sieves
for separating.
Storage
Rock that has undergone primary crushing is stored to ensure production continuity, and optimal homogeneity between rock
extraction batches.
Sitering
It is necessary to separate and control gypsum particle size in order to obtain the exact product properties required for the
plaster being manufactured.
Calcination
Calcium sulphate hemihydrates (CaSO4.½H2O) or plaster is obtained through the partial or total dehydration of gypsum at
a temperature ranging from 120° to 400°C The structure and properties of the final product are directly dependent on the
chosen calcination conditions (temperature, pressure, rapidity).Several types of calcinations processes exist:
4. Alpha Process
Alpha type plaster is used mainly in industrial plaster formulations for its high mechanical strength. This plaster type is a
compact crystal with a low specific surface and low water demands to produce hard, low porosity casts. Alpha plaster can
be formed through 2 different production procedures:
DRY PROCESS that involves injection of steam vapor during calcinations. The plaster is dried and then treated in
the regular manner.
WET PROCESS that involves calcinations of gypsum slurry under pressure. The plaster is then spun and dried.
BETA PROCESS
During the calcinations process, under regular environmental pressure, dehydration water evaporates and a micro-porous
structure is formed. Beta plaster crystals have a high specific surface and high water demands. Beta plaster casts have high
porosity, but low mechanical properties and are therefore, used in lightweight building applications or moulds in ceramic
applications for their absorbent properties. Often a mixture of both Alpha & Beta type plasters will be used to combine the
properties of both and optimize product solutions to suit market requirements.
Grinding
Following the calcinations process, the plaster is ground to obtain a powder. Particle size distribution is an important factor
in the product properties.
Mixing
With the plaster now in finely ground form, the final mixing stage is possible. A choice of additives will finely tune the
products properties to match the customer’s needs, in terms of setting time, viscosity, porosity, color, and mechanical
strength.
Testing
Laboratory testing is carried out at several production phases, to ensure allproducts meet the strict product specifications
before being bagged and shipped.
Packing
Feasibility studies are carried out to ensure the packaging item chosen for eachproduct gives optimal protection and
guarantees the product quality all the way tothe end-user.
Gypsum Machinery
Ball Mill Classifications:
Overflow Type
The overflow type of Ball Mill is designed to overflow and discharge materials from the trunnion on the outlet side. By
combining it with a mechanical classifier or wet-processing cyclone, you are able to extensively use this type for grinding in
closed circuit or for special applications such as re-grinding in open circuit. Generally, it is best suited to fine-grind
materials up to the particle sizes ranging from 150 to 200 mesh.
Grate-discharge Type
The grate-discharge type of Ball Mill has a grate at the outlet of the shell and
causes less excessive grinding, compared to the overflow type. Therefore,
generally, it is best suited to grind materials up to the particle sizes ranging
from 60 to 100 mesh.
Compartment type
The compartment type of Ball Mill has a longer shell, inside of which is
comparted into 2 to 3 chambers with grates and is best suited to produce
products grinding from coarse particles of some 25 mm to fine particles of
5. some 200 mesh.
Ultra Fine-Powder Ball Mill
Similar with horizontal ball mill, continuous production, but grinding chamber and grinding time is longer.
Batch Ball Mill

VSI Crusher
The working principle of VSI Crusher (sand making machine) has mainly
stone hit the stone (material against material) andstone hit iron (material
against iron).
Stone hit the stone (material against material): through the hopper, the
material enters into the crusher, and is divided into two parts by bulk cone. A
portion of materials falls into the high-speed rotation swing wheel, and is
rapidly accelerated. Then it is thrown away from the swinging wheel. This
parts material hit another part material, which falls down from all round of
the bulk cone.
Stone hit iron (material against iron): The basic work principle is similar
with “stone hit the stone”. The difference is that the crushing cavity of "stone hit stone" installs the impact board, and the
material forms material lining. But “stone hit iron” use the around guard plate replaced the lower guard board, and the
material directly impact on the around guard plate and broken.

Rotary Dryer
Despite the introduction of new technology, the long established Rotary Rotary Dryer is still widely
regarded as the workhorse of many process industries. The robust yet simple construction combines
flexibility with reliability, enabling this type of dryer to handle a vast range of materials and to operate
9. continuously under the most arduous conditions. The design also permits the use of the highest possible
drying temperatures and in contrast to other dryers is not sensitive to wide variations in material size,
moisture content or throughput.

Principles of Operation
In its simplest form, the Rotary Dryer consists of a slightly inclined rotating cylinder, fitted with a series of
peripheral flights arranged to lift, distribute and transport the material. The flights are designed to suit the
particular handling characteristics of the material, which may vary with increasing dryness. The principle of
operation is based on showering, or cascading the wet material through a hot gas stream, flowing either
co-current or counter-current to the solids. The hot gas induces the evaporation of the moisture. The heat lost
to the material and evaporation of water vapor reduces the gas temperature rapidly, such that it leaves the
dryer at a comparatively low temperature. The efficiency of the dryer is largely dependent on the differential
between the inlet and exhaust gas temperatures, although the heat transfer rate is also influenced by the
relationship between the design of flights and the speed of rotation. However, irrespective of the gas and
material temperatures the drying (or residence) time may be critical, as this is governed by the rate of
diffusion of water from the core to the surface of the material. For special applications, the rotary cascade
design is adapted to provide a shortfall, or ‘Cruciform’, lifter configuration.
Rotary Kiln Application
Rotary kiln is a rotating cylindrical vessel which is used for drying, calcination and sintering in a continuous process with
the use of hot gases. The hot gases may be generated in an external furnace or by a flame inside the kiln. Hengyangrotary
kiln and sponge iron rotary kiln has been developed for performing drying, calcination and sintering work in a continuous
process. Widely used for cement, pet coke calcination, dolomite, bauxite, sponge iron and other materials, it uses hot gases
for the operation. Integrated with variable speed drive, process automation and instrumentation, this kiln ensures optimum
operational control. In addition to technology, its design features better inlet and outlet sealing to ensure minimum false air
entry.
