Mass Finishing System

Vibratory Finishing Machine vailable in bowl volumes ranging from 30 to 1000 litres. The bowls are rubber or polyurethane lined for durability. Parts, media and compound are placed in the machine for processing. In the forward mode, the machine runs counter-clockwise and parts are processed.

Steel Shot

STEEL ABRASIVER

        Steel Shot is manufactured from scrap  steel through a well controlled casting  process. Various additived are added to  ensure a consistent quality produuct.  Steel Grit is produced through crushing  of steel shot and is subsequently heat   treated-tempered to three different hard-ness to cater for various applications.

APPLICATIONS

        Steel Shot and Grit are used for preparing  surfaces, cleaning the toughest forging,etching mill rolls, brightening finished,shot peening aircraft parts to increase fatigue strength, reduce wear and friction  and to relieve stress and special surface  finishes. The grits are also designed for  granite cutting.

Rosler Rotary Vibrators set new standards

Successful mass finishing applications are usually the result of a combination of creative process technology   and innovative equipment engineering. This approach is reflected in the varied line of Rosler rotary vibrators  with their enhanced performance characteristics. They combine Rosler's high equipment quality and  reliability standards with a functional design. In addition, they are easy to operate and provide  a high degree of productivity.

A technology that saves cost!

Rotary vibrators - Technical details

      Rotary vibrators made by Rosler Our highly efficient and flexible machine sysems offer virtually  unlimited finishing solutions. And our engineers and process technology experts are continuously working on further technical improvements. Convincing technology


1 Work bowl
   All our process bowls undergo heat treatment after welding for stress relied.
      ► Process water supply connections
      ► Large access doors for easy adjustment of imbalance weights
      ► Many process bowl variations for easy customization of the equipment
2 Integrated separation unit
   The machine types EC, Euro, Euro-HS, Euro-KP, Long Radius and  Long Radius-KP are equipped with intermal separation. The vibration caused the media and finished parts to move across the separation screen. The media falls through the screen openings back into the work bowl, while the finished part are moved to the machine exit.
     ► Separation flap or hand insertable separation gate - for the Euro, EC and Lr range
     ► The robust separation flap is activated by an external pneumatic cylinder (Euro range, optional for EC models)
     ► Vibration-resistant screen mounts (wedges)
     ► Spray rinse system over separation screen (optional) 2a Screening of undersized media
     ► Undersize screen segment: Optional in EC, Euro, Euro-HS and LR range
3 Wear resistant lining of work bowl
   Rosler manufactures its own wear-resistant linings. Prior to lining  the inside of the work bowl is shot blasted for better adherence of the wear linings. The following optional linings are available:
      ► Molded polyurethane
      ► Sprayed polyurethane
      ► Glued-in rubber or polyurethane sheets4 Media unload plug  Double function: Media removal from the work bowl and main drain  for the effluent from the work bowl. Can be cleaned from the outside

8 Setting of the imbalance weights The two basic upper and lower imbalance weights are securely fastened to the motor shaft. The offset angle can be easily set with the help of a shaft mounted disc indicating various angles. Depending on the required vibratory performance, additional imbalance weight plates can be easily added. 

9 Electrical control Relay controls or a PLC (optional) allow the central control of all machine functions. 

10 Process water supply 
        ► Separate flow controls for fresh water and compound supply
        ► Process water recycling systems optional  Extras:
        ► Circular spray bar for even distribution  of the process liquid in the work bowl  
        ► Spray-rinse above the screening area
        ► Flow control for water and compound  High Speed systems  "High Speed" rotary vibrators porduce an  up to 50 % higher grinding performance.  Depending on the parts to be treated and the required grinding results they represent a real alternative to standard rotary vibrators. Available in the Euro-, A- and R-range as fully automatic double or triple batch systems.

 

Longevity and high quality
       Rosler rotary vibrators are setting high technological standards. Their functional  desing, the use of high-quality materials and excellent workmanship guarantee a long service life and low maintenance costs. High quality powder coatings and industrial grade paints guarantee a long-term attractive appearance as well as corrosion protection. Upon request special paints and colors are available.

      

Rotary vibrators - EC range

"EC"... Rotary Vibrators
        Due totheir specially designed process  channel, rotary vibrators, type EC, are truly general purpose machined: The relatively shallow incline of the process channel in the EC machines allows the processing and esparation  of small as well as large parts. EC machines are also ideally suited for finishing of delicate parts.

Features:
        ► Shallow incline of the processing channel
        ► Manually insertable separation gate or pneumatically activated separation flap (option)
        ► large-surface and easy to change separation screens (screen change does not require any tools)
        ► Rosler double-flange vibratory motor with 2 speeds (1500 and 1000 rpm at 50 Hz); easy and safe lubrication of the bearings
        ► Adjustable imbalance weights allow different grinding intensities
        ► Wear resistant lining made from hot poured polyurethane
        ► Media unload plug with integrated effluent drain
        ► Flexible design of control panels and compound dosing systems Extras:
        ► Variable speed of vibratory motor
        ► Extra bootom drains

        ► Undersize media classification: Integrated into media unload plug or separate segment on separation screen

Rotary vibrators - Euro range

Automatic separation:
     The spiral bottom process channel and the pneumatically activated separation flap facilitate automatic separation of media and parts.

Option:
     ► Rinsing of the separation flap Gate clearing By reversing the rotational direction of the vibratory motor and subsequent sliding of the imbalance weights by around 190 degrees, the parts/media mass is moving backwards and clears the ramp area of  media and parts. This allows the separation flap to move into position without "catching" any media or parts.
