Bowl mills suitable for catering to coal throughput from 10
TPH to 120 TPH.
BHEL provides Bowl Mill with
Static or Dynamic classifier as per requirement.
Spring or Hydraulic loading.
Planetary or Worm Gear
Pulverisers are one of the major auxiliaries in a coal fired thermal power station. They are
used for grinding the pre-crushed raw coal, so that the pulverised product at desired PF
fineness can be fed directly to the furnace of the steam generator.

Tube Mill Size Vs Capacity in TPH
Mill Bowl Size Vs Capacity in Tonnes per hour (TPH) Ball Tube Mill is basically horizontal
cylindrical tube rotating at low speed on
its axis, whose length is slightly more to its
diameter. The inside of the Cylinder shell
is fitted with heavy cast liners and is filled
with cast or forged balls for grinding, to
approximately 1/3 of the diameter.
Advantages of Ball tube mills include
high availability, low maintenance,
constant capacity and fineness, hard
and abrasive fuels ground efficiently,
large reserve capacity, increased
fineness at low loads, fast response of
over range, low air-to-coal ratio, ability to
pulverise a wide range of coals, virtually
unaffected by foreign material and the
flexibility of available capacity.
Tube mills suitable for catering to coal
throughput from 30 TPH to 110 TPH.
Bowl Mill is basically a vertical Mill
rotating at Moderate speed (30 to 60
rpm) about its axis. It is recognized as the
most advantageous design of the coal
pulveriser because of its low initial cost,
low maintenance cost, removal of tramp
iron, low power consumption, easy
maintenance, wide range output & quiet
operation.
We also supply PULVERISERS suitable for
grinding Pet Coke / Lime Stone.
STATE OF ART FACILITY
BHEL Hyderabad designs and manufactures Planetary and Worm Gear Boxes for
Coal Mills. With the commercially available software’s like KISS-SOFT, UNIGRAPHICS,
HYPER-MESH and ANSYS, we model and optimise the Gear Box according to Mill and
customer requirement.
GEAR BOXES FOR BOWL MILLS
PLANETARY GEAR BOX:
Epi-cyclic or planetary gearbox is lighter,
compact, efficient and stronger than other
Gearboxes of same capacity.
Being more efficient makes it to consume
less power compared to other gear drives.
Exclusive Test Bed for Planetary Gear Box
Worm Gear Box Assembly (Mill base
Type)
WORM GEAR BOX:
With Worm gearbox high velocity reduction can be achieved within the same volume
compared to other drives.
The worm gear drive is provided in two variants: Mill Base type and Withdraw-able type.
With vast experience in Gear Box Technology, we provide the following services:
Replacement of Triple Reduction Gear Box of E –type Mill with Planetary Gear Box.
Conditional/Life Assessment of Old gear Boxes.
We also provide services to other types of Gear boxes given for other applications (other
than Coal Mills)
We can also provide suitable gear boxes for other applications.
