LHY ribbon mixer

Introduction:
LHY horizontal ribbon mixer is widely used in chemical, pharmaceuticals, food, and construction line. It can be used to mix powder with powder, powder with liquid, and powder with granule. 

Under the driven of motor, the double ribbon agitator mix the material quickly.  This ribbon mixer is characterized by high mixing effect, large productivity, and a very low failure rate. Since it is a batch type mixer, customer should choose the model according to the output per batch.

1.Flexible material selection
Material can be chosen from carbo steel, manganese steel, ss304, 316L and 321; besides, different material can also be used in combination.
Material is different between the part contact with the raw material and the parts don’t contact with the raw material.
Surface treatment for stainless steel include sandblasting, wiredrawing, polishing, mirror polishing, all can be used in different parts of a mixer.



2.Reliable driven unit
The driven unit, power and output speed are varied according to different raw material, starting method, and processing.
Options for motor: general motors, explosion-proof motors, variable frequency motor, high efficiency and energy saving motor. 
Commonly used reducers: R-series, K-series, and F-series gear box; cycloidal reducer, universal gear reducer, planetary gear reducer. Commonly used connection: direct connection, pulley connection, hydraulic coupler connection.




3.High efficiency mixing unit
Different main shaft agitators can be equipped according to the properties of raw materials.
Materials commonly mixed are: different kinds of powder to be mixed with each other, batches mixing for the same material, powder with a small quantity of liquid, liquid with some powder, like slurry, thickening or diluting slurry, granule with powder, granule with granule, agglomerated material breaking and mixing, and cooling or heating. 
The main shaft agitator could be: inner and outer ribbon, paddle and ribbon, disconnected ribbon, and shaver-shaped agitator.



4.Excellent discharging unit

Standard valve for horizontal plough shear mixer is pneumatic planar flap valve. When close the valve, the planar flap match the mixing barrel perfectly, this makes no mixing dead zone and better mixing effect. 
The drive types of valve are Manual, pneumatic, and electric.
Valves for consideration: powder spherical valve, cylinder valve, plum-blossom dislocation valve, butterfly valve, rotary valve etc.



5.Various inlets
Various inlets on the top cover of the barrel can be designed according to different situations. 
They can be used as man hole, cleaning door, feeding hole, vent, and dust colleting hole. The top cover can be designed as fully-opened lid for easy cleaning. 





6.Powerful auxiliary components
Mixer is frequently equipped with many auxiliary components, like steam coil jacket, honeycomb pressure jacket, medium circulation jacket, sampling valve, high speed chopper, temperature sensor, weighing system, dust removal system and so on. 
Different heat medium requires different jacket, it can be used for heating and cooling, while, the temperature should be within 250 Celsius degree.
If a small quantity of liquid is required during mixing, spraying or atomizing unit is necessary in order to mix the liquid evenly with the main ingredient. The liquid-adding system is basically composed by the three parts: pressure source, liquid storage pot and spraying nozzles.




7.Tight shaft sealing
Three types of main shaft sealing for mixer: packing sealing, combined type air-purged sealing, mechanical sealing are used for granule, powder, micron grade powder, liquid, and slurry material. 


 




Working principle:
Horizontal ribbon mixer is mainly combined with mixing barrel, agitator, driven unit.Untwist double ribbon are swirled with the main shaft in the U shape barrel. The outer ribbon push the material from the two ends to the centre, inner ribbon push the material from center to the two ends.Thus to achieve material convention

The discharging port is set in the bottom centre, with the help of the outer ribbon,the material can be discharged completely, and no dead zone.

Selection way: 
1. Choose the batch working volume from 0.1cbm to 20cbm, select mixer accordingly.
2. Choose raw material for the part contact with raw material, non-contact with raw material, other parts like motor and reducer, bearing material can not be chosen; According to the material to be mixed, processing condition, health level, raw material can be chosen from mild steel, sus304, sus316L, sus321; And choose the surface treatment according to the raw material.
3. Motor power is chosen according to the material gravity, fluidity, and operation. 
Operation is divided as: Start mixer when it is empty (normal duty)Start mixer with load (heavy duty)
4. Adding the auxiliary components like spraying, heating and cooling according to processing condition. 
5. Mixer inlets: feeding ports, cleaning port, vent.
6. Chose discharging and driven mode: manual, pneumatic and electric.

Note: mixer selection is a very important step, your detailed material information, processing and factory arrangement is very helpful to get professional technical support from us. 


Brief production line


Configuration 1: using  crane to hang bigbag material and feeding the mixer with the help of dust collector.
Configuration 2: mufti-level platform, manual undo the bag, mixing and packing with a bulk bag packer.
Configuration 3: simple mixer frame, feed a discharge directly with the help of a folk lift.



Configuration 1: using manual feeding platform, after mixing, screw conveyor send the material to the production silo, a packer under it. 
Configuration 2: using vacuum feeder, load the material on the ground, after mixing, pack with a bulk-bag packer.
Configuration: multi-stage vacuum feeder, store it after mixing, then packing.




Configuration 1: multi-level operation platform, levator sending to material silo, mixing, storage, and then packing. Tower structure. 
Configuration 2: bulket elevator feeding, mixing, storage, and packing.
Configuration 3: vacuum feeding, mixing, storage, packing.
Configuration 4. Manual feeding, mixing, storage, packing.
