LIFTING LINERS
The duty of the lifting liners is to give the proper motion to grinding balls in order to crush the raw material inside the 1st chamber of the tube mill. The lifting liners are used for initial coarse grinding of the material to be ground. The main types of these liners are called as;
XSTEP™
XLIFT®
MONOSTEP®
 
XSTEP™ LIFTING LINERS :
 
Xstep™ lifting liners are used in the 1st compartment of a cement or raw mills. It consists of 2 light channeled A and B plates. It creates a super well-balanced 3D-profile therefore
- It provides continuous lifting effect to the balls
- It provides optimal cascading ball trajectory.
 
Xstep™ liner design – 3D profile and spe  cific circumferential channels – was initially invented and optimized further to a widely full program of DEM simulations. Finally, the models were tested under extreme conditions in terms of  %Vc, %FD and φ max, global impact conditions, and proved its final design structure for industrial use.
 
 

Commercial Name:  Xstep™
Industry                 : Cement
Place of use          : Ball mills – 1st compartment
Key Benefits : 
Better contact amongst the balls;
       Optimized design and shape
       Improved permeability
       Reduced dead zone inside the motion of the balls
Lesser risk for ball projection and almost preventing the undesirable impacts;
       Continuous grinding efficiency
       Lifting shape remains the same until the end of life
Ball trajectories are ultra optimized ((charge opening, cascades, and light cataracts)
Ultra life up to 30.000 hours
kWh/t is reduced: approx -8% in specific energy consumption
t/h output is increased: approx 10% in production
Easy maintenance and quick installation: cost saving

Technical Specifications:
Tube mill in diameters from 3,0 to 6,0 m.
Suitable for DIN-drilled mill shells (250 x 314 mm), suits also Russian Shell drills (500 mm)
Available classical DIN-bolted or semi-vaulted versions
Lifting heights are;
           Plate A: 85 to 95 mm
           Plate B: 105 to 130 mm
Unit weights are; 
           Plate A: 35,4 to 39,3kg
           Plate B: 40,4 to 50,8kg
The inner metallurgical composition suits applications.

Material Options: 
A very good product to be used in the 1st compartments of the cement ball mills. Different alloys are available to match with the specific needs of the process conditions such as;
FMU11 alloy : CEM I (OPC), CEM II (composite cement with limestone), and raw meal grinding mills with ordinary running conditions in terms of %Vc, %FD, φmax, free SiO2
FMU33 alloy :  CEM V (compound cement with fly ash and slag), pozzolanic cement, CEM III metallurgical or blast furnace slag cement and full slag.
FMU10 alloy : raw meal grinding mills with higher impacts and improper filling degree.
 
XLIFT® LIFTING LINERS :
Xlift® Lifting liners are a modular all-of-a-kind design having 3 versions, (A.B, and C) and light in weight and resistant to wear.
Commercial name :  Xlift®
Industry : Cement
Place of use : Ball mills – 1st compartment
Principle : 
The Xlift® design concept was designed on the basis of 3 different plates having three lifting effects. The plates can be used as a combination in the 1st compartment of the ball mill according to the process parameters such as speed of rotation, material to be ground etc. So, it enables proper lifting along the mill axis and circumference.
 
 
Technical Specifications:
DIN drilled tube mill in diameters from 3,0 to 5,4 m 
Liner weight is min 18 kg, maximum 24 kg
The liners are settled by the bolting of wedges each every 7 to 8 rows.These wedges provide enough torque distribution to the whole lining.
Equivalent lifetime performance compared to step design liners.
 
Key Benefits:
Liner weight is reduced by 7 to 20% compared to bolted step liners. Weight is also reduced compared to other vaulted or boltless liner designs.
Better safety for workers due to light weight 
Optimum level grinding performance
Liner profile and/or lifting is adapted acc to operating parameters for grinding optimization.
Lesser maintenance: saving time and money
Short delivery time due to the standard design, availability from stock.
 
MONOSTEP® LIFTING LINERS :
Monostep® Lifting liners secures continuous lifting motion, slight expansion of material and ball charge. It also creates minimum dead zone inside ball motion, significantly reduces wears in the balls and shell liners
Commercial name : Monostep®
Industry : Cement, Mine, and Utilities
Place of use : Ball mills – 1st compartment




Technical Specifications:
Monostep® lifting liners are available in 3 different versions;
           A  type                            B type                            C type
Two major material option is available:
        Martensitic steel when more resiliency is required
        48 – 62 HRc hardness and 11% - 27% chromium content cast iron in order to avoid major wear problems.
It can be installed as bolted, semi-bolted or boltless.
 
Key Benefits:
Lower wear figures
The energy usage is optimized.
