Parameter Introduction
The double roll crusher mainly consists of the following parts:
Rollers : Two parallel cylindrical rollers (one fixed roller and one adjustable roller) with toothed, grooved or smooth surfaces, made of high manganese steel or other wear-resistant materials.
Transmission device : The electric motor drives the roller to rotate in the opposite direction through a pulley or reducer.
Adjustment device : The discharge particle size is controlled by adjusting the gap between the two rollers (wedge block or hydraulic device).
Spring safety device : Automatically separates the rollers in case of overload to prevent equipment damage.
Product Uses
Mining industry : crushed coal, iron ore, gold ore, etc.
Building materials industry : crushed limestone, gypsum, slag, etc.
Chemical industry : Processing brittle materials such as fertilizer raw materials and coke.
Other : Crushing of glass and ceramic raw materials.
Features
It has a simple structure and low maintenance costs.
The output particle size is uniform (usually adjustable within the range of 2-10mm).
Overload protection function to prevent equipment damage.
Suitable for fine crushing of materials with medium to low hardness.
Technical parameters
Specifications: 200*240
Feed particle size: ≤ 10
Discharge particle size: ≥150
Processing capacity: 300
Motor power: 1.5
Grinding degree: fine grinding mill
Application areas: mining, chemical industry, cement, refractory materials, abrasives, building materials
Working principle
The material enters between the two rollers through the feed port.
Two rollers rotate in opposite directions, using friction to carry the material into the crushing chamber.
The material is crushed under the squeezing, shearing and splitting action of the rollers.
The crushed material is discharged from the gap between the two rollers, and the discharge particle size is determined by the gap between the rollers.
Selection Guide
Key points for selection :
Select the roller surface type (toothed/smooth) based on the material's hardness, moisture content, and particle size requirements.
Match the roller diameter and speed according to production capacity requirements.
Pay attention to the compatibility between motor power and equipment load.
Maintenance recommendations :
Regularly check the wear of the roller surface and repair or replace it in a timely manner.
Keep the bearings lubricated and avoid high-temperature operation.
Adjust the spring pressure to ensure sensitive overload protection.
