General Introduction

Unlike those sand makers which are working under the principle of stone impacting stone, VSI can boast with a double capacity, and 20% in terms of 0.08mm sand size. VSI Sand Making Machine is widely used for artificial sand, in metal and non-metal ores, cement, refractory material, bauxite, silicon carbide, glass material, building material.

Application

Tertiary Crushing 

Mining, Aggregate, Metallurgy, Industrial, Construction, Environmental

Features
1. Superb Cubic Shape

2. High Crushing ratio, high productivity

3. No blocking in the cavity

4. Convenient Maintenance

5. Low cost

Working Principle 

The materials fall into the impeller from the head of the machine and with the function of highspeed centrifugal force, they strongly hit against and highly grind the other parts of the materials bypass flowing around the impeller in an umbrella form.After mutual impact and between the impeller and the machine shell, the materials will move like a vortex and will be impacted, rubbed and pulverized many times. Then they will come to the required fineness controlled by screening equipment, and discharge from its bottom.

 

Our Company:
Kunshan Duoling Heavy Machinery Technology Co., Ltd (in short, DL) was renamed from Shanghai Duoling-Watson Machinery Co., Ltd, a Sino-British Joint Venture founded in February 1985. In 2015, to further expand our production scale, the company was moved from the downtown area of Shanghai, to Jinxi Town, Kunshan, a picturesque scenic spot in half an hour's drive away. 
As a professional crushing machine manufacturer in China, we specialize in design, manufacture and sale of more than 100 kinds of stone crushing machines including jaw crushers, impact crushers, vibrating feeders, vibrating screens, and crushing plants etc. These crushing machines can be used as mining machines, engineering equipment and construction machines and so on.
Duo to their reliable quality, stable performance and high production efficiency, the crushing equipment can be used in mining, metallurgy industry, building industry, road construction, chemical industry, and other fields. 
As an experienced stone crushing machinery manufacturer in China, we strive to provide high quality crusher machinery for our customers at competitive price,therefore, we continuously introduce internationally advanced manufacturing technologies and implement strict quality control and cost control in the production of cone crusher, impact hammer crushers, and screening plants and other crushing machines. Every production procedure, including the purchasing of raw materials and production of even a bolt and a nut, is inspected strictly. Besides, our experienced staff, advanced CAD (computer aided design) system and computer simulation test system help to ensure the quality in every process. 
With 30 years of experience, we can now produce various high quality crushing machines with the characteristics of high quality, easy operation, reliable performance and long service life etc. Our PYH Series hydraulics cone crusher is the most advanced crusher in the world. Furthermore, we can design the fixed, semi-mobile and mobile crusher plant with capacity from 50T/H to 2000T/H. Up to now, we have passed ISO9001:2000 certification, and our crusher machines are well received by our customers in more than 20 countries and regions including Canada, Italy, Japan, Australia, New Zealand, South Africa, Chile, Thailand, Malaysia, Middle East, Russia, Kazakhstan, Indonesia, Iron and Malta etc. We would like to cooperate with more customers from all over the world.
