Crushers for Gravity Separation Machine
Introduction
Two Toothed Roller Crusher is also called teeth roll crusher, which is also a kind of roll crusher. Toothed roll crusher has two relatively rotating rollers with sharp teeth on them. The roller is generally made of special wear-resistant materials. During the working process of the two rollers, they have relatively high rotating speed, so that the material can be split. Fote toothed roll crusher can be divided into double roller crusher and four roll crusher series, customers can choose freely according to their own needs.
With large feeding size range and adjustable output size,it is also to crush materials with ≤1600Mpa comperssive strength,such as cement and silicate industries.It is usually replaced by cone crusher in metal mines.However,the rouller crusher is still being applied in small scale mines ore precious ore mines crush materials with little soil(e.g. Tungsten ore)
Application
Two Roller Crusher is widely used for crushing high hard and medium hard materials in such industrial departments such as metallurgy, building material and refractory.
It is mainly used for secondary crushing or tertiary crushing of raw materials such as coal, coal gangue, coke, limestone, sulfur ore, phosphate rock and other materials.
Working Principle
The two rollers have wedge or gasket adjusting device, wedge device with the top adjustment bolt, when the adjustment bolt wedge block upward pull up, wedge will activities roller top from fixed wheel, two roller gap becomes larger, the discharge size becomes larger, when the wedge block down, activity roller compression spring (or pressing oil cylinder) under the action of two gap becomes smaller, the discharge size becomes smaller. Gasket device is through increase or decrease the number of gasket thickness to adjust the size of the discharge size, when adding gasket will make two roller wheel gap bigger, when reduce gasket will make two roller wheel clearance decrescent, the discharge size becomes smaller .
Feature
1. High crushing capacity, safe and reliable
2. Roller spacing hydraulic adjustment, roller bearing lubrication
3. Tooth profile optimization design, tensile shear selective crushing, discharge material evenly
4. Convenient repair, overload protection, sensitive, safe and reliable
