SKIRT BOARD IMPROVEMENT

                                   


                                              Skirt Board


Each transfer chute certainly equipped with the skirt board. skirt board has a very simple function, namely :
1.Direction fall of material into the central conveyor,
2. Then prevent material spilling out of belt conveyor, 
3. Control dust with the collecting filters.

If the design and handling is not maximum, it will cause some of the possibilities of such spillage, live time of skirt  rubber very short ,and  top of belt conveyor experiencing very rapid abrasion.

For counter all caused of improper maintenance or design , we have best solution for improve skirt board refer to our technology , all of our 16th improvement project ,we have positive feed back from our costumer. 




                                   

                                            Material Selected

Costumer can make a choice for selected material, basic material also very simple but price will different. that material of wear liner include SS304,SS306,creusabro, of CS106, skirt board used 

Benefit of Improvement

1. Reduce material Spillage

2.Eliminate cost of expensive skirt rubber

3.Simplify skirt rubber Maintenance access.

4.Extended life time of  conveyor belt .

5.Generally safe the maintenance cost

6.Reduce also bag log .

TRANSFER CHUTE LINER


                                            CHUTE LINER

      Transfer chute is a unit that is mounted on a conveyor belt system aims to direct and move material from one conveyor system to another.
This unit is equipped with many components that have the function of each to complete the transfer chute, including transfer chute wall, and completeness of the protective wall chute. Chute liner is important to protected wear rate that occurs in the walls of cute.This material consists of several types such as: rubber, ceramic, HDPE, verous and non ferrous material. all of these materials depends on the decision-makers of the conveyor designing.
      A lot of belt conveyor designer that makes research and new discoveries with saving considerations, safety and environmental  consideration.
 Transfer chute has complication failure, but many of this case is comes from chute liner. effected of damaged of chute liners with different impact. Wear of liners material will be impacted  to some of affect :
       1. Belt torn off.
       2. Environmental.
       3.Expenses.

                                        Belt Turn Off

  

  Maintenance team always finding belt torn off caused by release liner and fell down. Why that liners was fell down ? very simple answer but high effect damaged, that is come from looseness of fastening countersunk fasteners . Base of  experience, all that countersunk problem come from  abrasion and looseness.
When we analyse that problem,we are using Failure Mode and Effect Analysis ( FMEA) that is find  on the wear rate is very fast of the liner and countersunk head. 


                                     Environmental Effect

All surface of chute liner become wear out shortly caused by high abrasion of transporting material. If liner material made of high abrasion resistant, that will be take maximum two year. but if low material than will be very soon wear come out .

Every wear out of the chute liner will be effected to chute wall also wear. This wear out of wall chute  very fast because wall chute material made of low carbon steel , than material spill out to the floor. 
Material spill out, look very poor environment on the transfer chute floor, and also potential fire if flammable material. 

                                        Expenses effect 


Basic of economic calculation, both Conveyor Belt torn and Environmental effect, automatically  that will be effect to increasing yearly expense. So Management have to open mind to look at this problem close, analyse, evaluate, and make decision for improve transfer tower on the future.

                                           Remarks

We have solution for resolve all item above base on our skill and experience on the belt conveyor transfer chute system. special for the chute liner, we have excellent design of impact liner and sliding liners.
This both product will be saving a lot of maintenance cost :

       1. Superliner will be install for replace the impact liners , live time of superliner recommended
           above fifteen years it mean hundred times efficiency :

          Benefit of Superliner :

          a. Reduce noise
          b. Eliminate spillage
          c. Eliminate Fire hazard 
          d. Reduce bag log
          e.  Eliminate belt torn caused by fall liners.
          f. The final is Reduce Cost.

      2. Sliding liners has anti looseness fasteners at variant position,and also improvement liners
          material with anti corrosion and abrasive resistant material.

            Benefit of Sliding liners :

              a. Mounting bolt never loose anymore
              b.When liners was worn out, bolt can not loose.
              c. Eliminate material build up or bottle neck.
              d. Increase live time of sliding liners.
              e. Reduce spillage
              f. Eliminate Fire hazard 
              g. Eliminate belt torn caused by fall liners.
              h. Reduce bag log
              i. The final is Reduce Cost.

Maszacron-81 National Brand


                           INTRODUCTION OF MAZACRON-81 CARRIED 


The Maszacron-81 is one of the new brand for posted on the conveyor belt improvement parts include: Tertiary belt cleaner, Superliner (Chute liners name),self align idlers and skirt board improvement. Each of parts have unique characteristic when apply on the bulk material effect during transporting. For detail description and how to solve that all founding billow, please look at the Maszacron-81 items post.

Our costumer can make a choice to solve conveyor belt system, when this case billow was happened :

1. Impact chute liners material soft ,ceramic and extra strong - ferrous material. worn out very soon.

2. Liner chute wear out . This item always impact to system:

           a. The worn liners is failed to cut the belt.
           b. A lot of chute liners have to replace sooner  cause erosion.
           c. Environment Hazard - chute wall was leaked and material spilled out to the floor
           d .High cost maintenance.

Fig 2.2. Chute Leak at the Sliding Area.

3. Too many carry back on the top of belt conveyor.

            a. Build material on the return roller
            b.Build material on the bend pulley and gravity take up pulley.
            c.Belt conveyor always tracking on the return line.

4. Conveyor belt always tracking (move left /right or jogging ), pill of  belt edges .

            a. Pill off belt edges.
            b. belt cut off

5.Skirt board improper work :

            a. Too many spillage bulk material
            b. Skirt rubber  damaged very soon
            c. Trapped material between wear liner and top belt conveyor.
            d. Too many dust out .
