Product Overview
Double Roll Crusher (Roll Crusher) is a classic medium and fine crushing equipment which adopts the principle of extrusion and shearing. It is suitable for crushing hard, medium-hard and soft materials with compressive strength less than 300MPa and moisture content less than 35%. With its simple structure, convenient maintenance, low over-crushing rate and even product size, this equipment is widely used in mining, thermoelectricity, cement, ceramics, metallurgy, chemical industry, building materials and other industries, and is a reliable choice for completing medium and fine crushing operations.
Core working principle
The Double Roll Crusher applies huge squeezing and shearing force to the material through two high strength wear-resistant alloy rolls rotating in opposite direction. The material enters the V-shaped crushing chamber between the two rolls from the upper part of the machine, and is subject to multiple effects of extrusion, shearing and grinding, and is crushed to the required size, and finally discharged from the lower part of the machine. The granularity of the discharged material can be precisely controlled by adjusting the gap between the two rolls.
Product advantages and features
-
High efficiency and energy saving: The crushing principle is direct, high energy utilization and low energy consumption.
-
Controllable particle size: by simply adjusting the roller gap, you can easily change the size of the discharge, the product shape is good, less over-crushed phenomenon.
-
Simple and durable structure: compact structure, reliable operation, low maintenance costs, low failure rate.
-
Overload protection: Usually one of the rollers adopts spring buffer design, when encountering non-crushable materials, the rollers can automatically give way to avoid equipment damage.
-
Environmental protection and low noise: Compared with the impact crusher, the dust and noise are smaller, and the working environment is more friendly.
-
Flexible Application:Flat rolls and surfaced rolls are available to meet the needs of different materials and particle sizes.
