Introduction

Rubber crumb, also known as rubber granules, is produced when waste tyres and other rubber scrap are shredded, ground, and washed to remove dirt, fibre, and steel wires. After this washing stage the crumb still carries a considerable amount of surface moisture, often in the range of 8 to 15 percent, which makes it unsuitable for packing, storage, or direct use in downstream applications. Kerone’s Rubber Crumbs Dryer is built to bring this moisture down to below 1 percent in a controlled and consistent manner, so that the crumb reaches customers in a free flowing, uniform, and shelf stable condition. The dryer handles particle sizes ranging from coarse granules to fine powder without altering the physical or chemical properties of the rubber, and it is engineered to work as a continuous process step within a larger tyre recycling or rubber reclamation line.

Why Choose Kerone Rubber Crumbs Dryer

Kerone has spent decades designing thermal process equipment for demanding bulk material applications, and that experience shows in the way this dryer is engineered around the real behaviour of rubber crumb rather than a generic drying model. Wet rubber granules tend to clump, stick to hot surfaces, and generate static charge, all of which can choke a poorly designed dryer within hours of startup. Kerone’s design addresses these tendencies directly through careful control of air velocity, residence time, and drying temperature, keeping the rubber well below the point where it could scorch, degrade, or release unwanted odour. Every unit is sized against the actual feed moisture, particle distribution, and target output moisture supplied by the client, rather than offered as an off the shelf box, which means the equipment fits the plant’s real throughput instead of forcing the plant to adjust around the machine. Backed by responsive after sales support and a track record across recycling plants of varying scale, Kerone remains a dependable partner from the first feasibility discussion through years of operation.

Types and Features of Rubber Crumbs Dryer

Rubber crumb drying can be achieved through more than one mechanical approach, and Kerone offers configurations to match the specific granule size, moisture load, and plant layout of each customer. The rotary drum type passes crumb through a slowly rotating, slightly inclined cylinder while hot air flows through it, and it is well suited to coarser granules and higher throughput lines where robustness matters more than a compact footprint. The fluidized bed type suspends finer crumb in a rising column of hot air, giving very even heat contact and shorter drying time, which works well where floor space is limited but energy efficiency is a priority. Both configurations share a common feature set built around indirect or direct hot air heating, adjustable residence time, and construction materials chosen to resist the abrasive nature of rubber granules, and the choice between them is generally guided by the incoming moisture content, desired final moisture, and the space available on the client’s site.

Key Features

  • Handles a wide particle size range, from coarse crumb down to fine rubber powder, without segregation issues
  • Reduces moisture content from typical wash stage levels down to below 1 percent consistently
  • Construction in mild steel or stainless steel depending on the corrosiveness of the process and client preference
  • Adjustable air temperature and airflow to prevent scorching, discolouration, or odour generation in the rubber
  • Wear resistant internal fittings at high friction points to extend service life when processing abrasive granules
  • Enclosed design that limits dust escape and keeps the surrounding work area cleaner
  • Low noise operation compared to mechanical grinding and shredding stages upstream in the plant
  • Flexible heating source options including electric heaters, thermal oil, steam, or hot gas depending on utility availability
  • Modular sizing so capacity can be scaled from small pilot batches to full commercial throughput
  • Straightforward maintenance access with removable panels and accessible drive components for quick servicing

Applications of Rubber Crumbs Dryer

Kerone’s Rubber Crumbs Dryer is extensively used in industries that recover value from end of life tyres and rubber scrap. Typical applications include:
    • Tyre recycling plants drying crumb rubber after the wet grinding and washing stage
    • Production lines supplying rubber granules for synthetic sports turf infill
    • Manufacturing of rubberised playground and safety flooring tiles
    • Preparation of crumb rubber used as an additive in asphalt and road surfacing
    • Supply of dried granules for rubber mats, mouldings, and industrial flooring products
    • Rubber reclaims and devulcanisation plants that need dry feedstock for further processing
    • Export oriented rubber crumb units where consistent moisture content is a shipping requirement
    • Compounding units that blend dried crumb rubber into new rubber and plastic formulations
