The D.P. Micro Pulverizer is a high-speed hammer and screen mill,
which accomplishes size reduction by mechanically impacting process
material. This method of size reduction is characterized by relative high
energy and short residence time, minimizing heat build up during the milling
process.
Operating Principle
The D.P. Micro Pulverizer consists of a rotor assembly fitted with hammers
and operates generally at high speeds. A cover fitted with a liner, a
retaining screen at the point of mill discharge and a feed screw mechanism
whereby the unground material is uniformly fed to the grinding chamber.
The grinding action in the D.P. Micro Pulverizer is the impact between
rapid moving hammers and particles themselves. The energy of the moving
hammers dissipates itself into the particles by virtue of their inertia thus
causing size reduction.
Applications
The D. P. Micro Pulverizers, can be used for a wide range of application
e.g. Activated Carbon, Animal Feeds, Carbon Black, Chalk, Cocoa, Starch
Dyes, Fine Chemicals, Gram Flour, Kaolin, Pigments, Sugar, etc.
Outstanding Features
- Efficiency and Compactness.
- Quick and Easy Cleaning.
- Labour Saving.
- Long Service Life.
- Guaranteed Performance.
- Lowest Cost.

P. Micro Pulveriser No. 2D.P. Micro Pulverizer with Dust Collector
The D.P. Micro Pulverizers are also Available with Cyclone & dust
collector. This system performs a total dust free operations. As the system
consists of a blower at one end it is possible to pneumatically convey the
pulverised material to the required distance.
D.P.
Pulverisers manufacture a large variety of Impact Crushers to virtually any
size reduction job. The extremely rugged construction of Impact Crushers
ensures a long life with minimum maintenance easy to install and economical
to run. The shell of Impact Crusher is lined throughout with MS, Cast Iron
or Manganese Steel, according to the size of Impact Crusher and duty
required. We can provide a Impact Crusher to reduce almost any material to
the size required.
Operating Principle of Impact Crusher
Material is fed in Impact Crusher from the periphery through a hopper into
the grinding chamber to minimize air pressure, greatly reducing dust
problems. For some material suitable ventilation is recommended by
introducing air on the discharge side of the crusher, this will prevent a
dusty atmosphere at the inlet of Impact Crusher. The swinging hammers in
Impact Crushers crush the materials along the stationery liners before
discharging through a perforated screen at the bottom; replaceable bar type
screen is available for specific application. Combination of hammer style,
liner plates and sieve inserts offer almost unlimited possibilities to cater
user needs from an Impact Crusher.
Applications
of Impact Crusher
The Impact Crushers are used for crushing or shredding of diverse materials
such as: Limestone, Glass, Coal and Lignite, Clay, Sand, Phosphate, Rock,
Fertilizer, Aluminium Oxide, Slags, Coke, Silica, Bauxite, Dolomite, Grain,
Barytes, etc.
Outstanding Features of Impact Crusher
- Impact Crusher is specifically designed to withstand the abuse of
grinding of abrasive materials.
- Heavy duty, replaceable, abrasion resistance wears plates in mill
top.
- Heavy duty hard faced or heat treated hammers.
- Heavy duty rotor assembly.
- Rugged bar screen or thick perforated metal screens to size
materials.
- Impact Crusher is opted with Dust-tight or water-tight construction.
- All stainless steel construction available in Impact Crusher.

Air Classification is the process of separating particles according
to the settling velocity in a gas. Air Classifiers are used to separate dry
materials into different particle size fractions by their size, mass or
shape. Air Classifiers are used to modify a particle size distribution,
remove the fines fraction of a material or the over size or coarse particles
of a material or create two grades of material.
The D. P. Air Classifier is a compact and dust tight machine for fine
classification of various powdered materials. The air classifiers are
ruggedly constructed to high engineering standards to give long reliable
service life to the most arduous duties. Low operating speed ensures that
wear and tear is minimised when handling abrasive materials. Easy access to
the interior of the machine for inspection and cleaning is ensured by the
provision of generously proportioned inspection doors. The rotor is mounted
on heavy duty antifriction bearings which are located outside the machine
and protect them against ingress of dust. Due to self contained nature of
the machine all air flow is contained with the boundaries of the machine.
Operating Principle
In the cycle of operation, material enters the centre feed pipe and drops
upon the rotating distributor plate below, which disperses the material into
the upward sweep of circulating air developed by the fan in the top chamber
of the drum. The whizzer blades set up a centrifugal motion of the air and
material. This concentrates the oversize material along the surface of the
upper inner cone, where gravity causes it to flow into the lower inner cone
and then out the tailings spout at the bottom. The air stream carrying the
powdered material of required fineness moves through the fan and is
delivered into the outer cone chamber where the fines are discharged as
finished product. After the fines are released in the outer cone, the air
returns through the deflector ports to the inner cone, setting up a
continuous circuit.
Applications
The D.P. Air Classifiers are used for a wide range of applications e.g.
Cement, Limestone, Soya flour, Hydrated lime, Food Products, Chemicals,
Talc, Clays, Metallurgical Powders, Pigments, Fly Ash, Silica, Aluminium
Oxide, Graphite, Calcined Magnesite, P.V.C. Resin, Asbestos, Barytes,
Quartz, Feldspar, Coal, etc
Outstanding Features
- Strong construction of mechanism and casing ensures long life.
- Close control of over product uniformity.
- Minimum loss of fines in the tailings.
Special liners are available for processing abrasive materials.
