Product Overview
This Adjustable Discharge Gap Double Roller Crusher is designed for flexible particle‑size production requirements in mineral and aggregate processing. It is equipped with precise gap adjusting mechanism, allowing operators to quickly modify the clearance between two rollers without complex disassembly work. One single machine can produce multiple finished particle sizes to handle different ores, stones and industrial materials. It is highly versatile crushing equipment for mineral processing plants, aggregate yards and material recycling production lines.
Key Features
Flexible adjustable discharge gap for quick size change: User‑friendly gap adjustment structure enables easy modification of output particle range. No need to replace main wearing parts when switching product specifications. It saves production conversion time and improves equipment utilization rate. Users can freely switch between coarse, medium and fine granular outputs according to onsite production demands.
Heavy‑duty roller assembly and reinforced frame ensure stable running under variable working conditions. High‑strength wear‑resistant roller shells extend service life for processing hard, abrasive materials. Low‑speed extrusion crushing keeps low over‑crushing rate and well‑graded finished particles. Simple structure brings convenient inspection and maintenance, suitable for long‑term continuous production in multi‑material processing workshops.
Working Principle
Power unit drives two rollers to rotate synchronously towards each other. Feeding materials fall into the crushing cavity and get crushed by extrusion and shearing force between rollers. The finished products discharge through the gap between twin rollers. By adjusting the gap distance, users directly control discharging particle size. Narrower gap produces finer output; wider gap gives coarser granules, realizing fast switching of different product sizes on one machine.
Applicable Materials
Suitable for limestone, quartz, iron ore, coal, coke, shale, construction waste, slag and various medium‑hard brittle minerals and industrial raw materials. Ideal for sites requiring frequent switching of finished particle specifications.
Application Scope
Widely used in mines, mineral processing plants, sand aggregate production yards, coal processing plants, building‑material factories and solid‑waste recycling lines. It serves as multi‑purpose medium‑fine crushing equipment where multiple particle sizes are required from one machine.
Product Advantages
This gap‑adjustable double roller crusher stands out for simple size adjustment, strong versatility and high equipment utilization. One machine meets multiple particle‑size demands, reducing investment for multiple crushing machines. It delivers stable crushing performance, low over‑crushing rate and easy daily maintenance. It is a cost‑effective multi‑functional crushing choice for production lines with frequently changed material specifications.
