70-150 t/h Mine Crushing Equipment , Sand Crusher Machine VSI Impact Crusher for Sand Making Plant

Introduction

Sand Making Machine is widely used in fine crushing and rough grinding of metal, mineral, building aggregate, concrete, anti-fire material, glass raw material, manufactured sand and all kinds of metallurgical slug. It can be utilized in shaping of high rank road surface. Compared with other kind of crusher, it is more advanced in intermediate hard, extra hard and abrasive material.

Features

1. Advanced double-pump oil lubrication system guarantee shaft bearing lower temperature increase, longer life time, more reliable operation.

2. Main shaft is equipped with imported precision rolling bearing. It makes main shaft work stable, lengthen maintenance cycle, increase productivity.

3. Hydraulic lifting mechanism of upper cover can move away the cover easily, which saves man power during maintenance.

4. Over-vibration device is equipped. There will be alarm when vibration surpasses a stipulated figure. It will stop the machine, in order to protect it.

Working Principle

When enters into impeller, the raw material can be crushed directly by hitting impact plate after it is accelerated and threw out. The raw material can also be divided into two parts by material-dividing plate. One falls down from all around. The other enters into impeller and is accelerated, threw out and collides with the falling material and hit, rebound with impact plate. The circulation hits repeats. As the crushing is moving forward, small particle materials will gradually form a material bed around the impact plate which can improve the crushing effect and protect the machine. The desired artificial sand comes downwards though outlet finally.
