The Third Generation New-type Sand Making Equipment: VSI Sand Maker

Sand Maker is suitable for crushing and shaping soft or middle-hard or extremely hard materials, widely applied to pebble, rocks (limestone, granite, basalt, dolerite, andesite), iron ore tailings, artificial sand making of stone chips. Water conservancy and hydropower of engineering field, high-grade highways, expressway and railway, passenger railway, bridge, airport pavement, municipal engineering, sand manufacturing and aggregated rock shaping.
VSI Impact Sand maker is called as VSI Sand Maker for short, also called as The Third Generation Sand Maker or New-type Sand Maker. Senya introduced German technology, developed and manufactured this international level high performance new-type sand making equipment; it places an irreplaceable role in fine crushing.

DETAILS INTRODUCTION

Features and technology advantages:

Simple and reasonable structure, low cost
High crushing ratio, energy saving
Fine crush and grind
Moisture content of raw material up to about 8%
Suitable for crushing hard material
Excellent shape of final product
Small abrasion, easy maintenance
Noise when working is below 75dB

Working Principle of VSI Sand Maker:

The materials fall into impeller with high-speed rotation vertically. On the force of high-speed centrifugal, the materials strike to the other part of material in a high speed. After mutual impacting, the materials will strike and rub between the impeller and the casing and then be discharged straight from the lower portion to form a closed multiple cycles. Final product is controlled by screening equipment to meet the requirement.

TECHNOLOGICAL PROCESS FOR ARTIFICIAL SAND MAKING PRODUCTION LINE

This production line takes raw materials being less than 40mm as the example for introduction.

Step 1

The aggregate with size of 0-40mm pass through suspended-type vibrating feeder, than being transported to VSI sand maker by the rubble conveyor for crushing, the crushed materials will be transported to a two-deck vibrating screen for screening;

Step 2

The materials with size being smaller than 3mm will enter powder separator which will process the materials with size of 0-0.075mm, 0.075-3mm and 3-5mm respectively, then composing to be finished material pile;

Step 3

The materials with size being larger than 5mm will be returned to the sand maker for re-crushing, forming a closed cycle. According output requirements, part of the materials with the size between 3-5mm can be the finished products, and part can be returned to the sand maker for re-crushing;
