Refiner Mill

Refiner Mill

In rubber industry, while processing of rubber, there will always be some scrap, which is usually called “Waste” to meet breakeven point & for success of every industry, we need to minimize our wastage which is really possible through “SLACH HYDRATEC TWO ROLL REFINER MILLS”. Available in phosphorous bronze or anti friction roller bearings & bull gear universal drive. Ideal for breaking vulcanized compounds washing natural rubber. These models are designed & developed according to customer’s specific requirement.

Friction

Rubber refiner mill can have speed variable models with frequency controls options. Friction, speed, gap size, essentially all operating parameters can be stored in the PLC to be used next time if you have the same compound. Through friction different forces act on the compound, as mass- particles are being moved against each other as soon as the compound is compressed in to the gap between rolls. Friction also builds up roll turning in the gap which again helps homogenizing the compound.

Material Guides

At the ends of the roll faces the roll nip is being limited by the compound guide cheeks. The compound guide cheeks of split design with “center tongue” avoid lateral escape of compound from the working area in any case.

Roll NIP Adjustment

Adjustment of the front roll used to be made y hand (manual y ratchet). Today the gap between the roll is adjusted by gear motors individually mounted on both sides of the mill stand. Safety pads are provided between the coupling and the nip adusting screw. Auto adjustment can be done through LinearPotentio Meter/ Linear Scales with PLC. They also open roll gap immediately when pushing the safety bar in front or back in case of emergency.

Cracker Mill
Overview

The Cracker Mill is used for powder production of rubber originating from basically any type of tyre - e.g. car tyres, truck tyres, OTR tyres, mining truck tyres, van tyres, super singles and agricultural tyres. It consists of 2 parallel individually driven rolls. The rolls counter rotate in different and adjustable speeds (ratio) creating a friction between them. This friction generates tearing forces that breaks and tear the rubber apart.

  • The solid construction ensures smooth production
  • The bearings are lubricated by means of PLC-controlled grease pumps in order to ensure long life
  • The rolls are water cooled and the cracker mill includes a water cooler developed for this purpose only
  • The electrical system is designed to regenerate large volumes of electrical power resulting in energy savings
  • The control and soft touch panel show the friction ratio, overall mill speed, Amps, bearing temperature etc
