Product Description

High quality gravel making machine with 30-200tph

gravel making machine Introduction

gravel making machine is a high-performance vertical-shaft sand maker equipped with vertical shaft and imported originally from Germany, which specializes in crushing materials and shaping cube. With adopting the rock-on-rock principle, every material particle can be acted by an external force and the cube shape of crushed material is improved.


 
gravel making machine Working Principle: 
 
In gravel making machine, material of high speed is crushed by self-broken mutual friction. gravel making machine can not only crush but also shape stones. 
According to feeding method, centrifugal impact crusher working form is divided into central feeding and central with cascade feeding. The crush form is divided into "rock on rock' and "rock on iron" According to material compressive strength, abradability. There are four working forms: Central with cascade feeding "rock on rock" and rock on iron"; Central feeding "rock on rock" and rock on iron". 
 

gravel making machine Feature:
 
1. The material is not easily blocked;
2. The rotor is composed by detachable parts;
3. To avoid the probable vibration generated by crusher rack and motor in the working process, rubber shock absorber is installed in rack and motor;
4. The steel structure foundation bed adopts the welding structure;
5. Adopting the wear-resisting liner which can replace the mould bed is able to Increase crushing efficiency and Increase the rate of sand making. Sand maker can provide two selectable types for customers to transform quickly acco;
6. VSI Series gravel making machine without air circulation system reduces the height of the machine and makes the equipment more safe and stable;
7. The following installation of air circulation system is workable according to the requirement of customer.
 
gravel making machine Application:

1. Recycling of glass, Slag processing, Asphalt preparation, Crushing stone and finishing aggregate;
2. In the technology experiment center located in Sonthofen, gravel making machine can conduct industrialized crushing experiment with customer special materials, and find appropriate solution aiming at the most demanding requirement;
3. Every material particle spins rapidly in the double cavity type rotor which obtains a patent, and then it is thrown to the counter-attack board. Counter-attack board consists of ring liner and mould bed. The design of large size of rotor and shell can prevents clogging largely. Choosing the appropriate rotational speed can optimize the crushing effect largely;
4. Automatic oil lubrication system installed in appropriate position is easy to examine and maintain. Benefits are following.
