Hari Machines Limited, Committed to Customer Service & Striving
for excellence in machine design and manufacturing. Established in 1971,
it is a name that has through the years become synonymous to refractory
Machinery and Equipment in India.
Hari Counter Current Mixer: conventional
type with kneading roller has been designed and manufactured by Hari Machines Ltd. specially
for refractory application. Introduced in early eighties the machine became
very popular because of the unique counter current mixing concept. Today
around 150 number of such mixers are operating successfully at leading
refractory manufacturers in India. With the advent of high quality &
sophisticated refractories like magnesia carbon, alumina carbon, dolomite,
castables, etc. the need for quick & more homogeneous mixing was strongly
felt. Hari Machines Ltd. developed the High Efficiency Counter Current Intensive Mixer,
comprising of a high energy rotor for intensive mixing. It has remarkable
advantages over conventional mixer with regards to more homogeneous mix,
reduced mixing time & less maintenance.
Mode of Operation & Working Principle
- Operation is based on counter current principle. The mixing star &
high energy rotor are eccentrically placed & rotate in counter clockwise
direction within the clockwise rotating pan.
A very high mixing effect is achieved with the pan, mixing star &
high energy rotor having opposing rotational speeds subjecting the batch
to constant change in position & speed in both horizontal as well
as vertical direction.
The high energy rotor intensifies the movement of the material particles
resulting in intensive blending of the material. Moreover the batch is
rapidly & completely homogenized & de-nodulised.
The mixing star comprising of four mixing blades placed at different levels
force the batch in the vertical movements as well because of their specific
pitch.
Stationary wall scrapers guide the batch particles so as to take active
part in mixing process.
SALIENT FEATURES
| • |
Quick & Efficient
Mixing
The combination of mixing star & high energy rotor (with the option
of 2 speed or infinitely variable speed) ensures quick & homogenous
mixing. |
| • |
Heavy Duty Application
Rigidly mounted mixing blades & heavy duty ball bearing supported
high energy rotor are not susceptible to shocks even under heavy duty
operation. |
| • |
Smooth Operation
Smooth & noise free operation is ensured even under heavy loads
by specially designed slewing ring which guide the pan in both horizontal
& vertical direction. |
| • |
Effective Sealing
Spillage free & dust proof operation is ensured due to increased
pan height and special double seal arrangement in pan. |
| • |
Quick & Complete
Discharge
Quick & complete discharge of material is achieved by motorised
discharged system. Optionally, Hydraulic actuated discharge mechanism
is also available. |
| • |
Auto Mixing Cycle
Mixing time & speed of high energy rotor can be preset. Single cycle
operation of mixer excluding dosing (manually) is accomplished through
PLC. |
| • |
Easy Maintenance
A large hinged door provided on the rotating pan wall can be positioned
to any desired location giving easy access to inside of the pan. Also
individual drive arrangement ensures the elimination of gears &
pinions, thus reducing maintenance |
| • |
High Reliability
High reliability is ensured since all greasing points are connected
to centralized lubrication system. |
