Sand making machine Description

Yufeng vertical shaft impact crusher also know as sand making machine is applied widely for the powder process of mineral product including mental and non-metal ore, fireproof material, bauxite, diamond dust, glass raw materials, architectural materials, artificial sand and all kinds of metal ore materials, especially which has more advantages than any other machines in processing the more and most hard materials.

Sand making machine's usage

This series of sand making machine has a wide range of uses, Its performance has reached the international leading level in sand-making equipment lines. It is the most effective, practical and reliable sand making equipment. The sand making machine is particularly applicable to the production of building sand ( bluestone, limestone, bank gravel, rocks, granite and many kinds of raw matierials to make building sand), abradant, refractories, cement, sand, emerry, slag powder, copper ore, iron ore, gold ore, concrete aggregate, asphalt aggregate and many kinds of hard, brittle material's fine crushing and secondary crushing. It is a high efficient and energy-saving equipment for sand stone crushing. It can save 50% energy than the traditional machine. It is the most advanced sand making equipment in the world

Feature and Benefits:

1. Simple structure, low cost.
2. High efficiency and low consumption.
3. Primary and second crushing capacity.
4. More and most hard materials can be crushed.
5. Cubic shaped final product.
6. Little noise and dust pollution.
7. Convenient performance, maintenance, installation.

Working Principle:

The Whole vertical shaft impact crusher including feed hopper, classifier, whirlpool cavity, impeller, main bearing assembly base, transmission device and motor etc.
Operation principle is as follows: the materials enter the crusher through feeder hopper, which is divided into two parts, one part through the middle of classifier entering into the rotating impeller at high speed, then accelerated, whose speed can reach hundreds of acceleration, then is shot through the tunnels around the impeller by the speed of 60-75 meter/second. First the materials will impact with some materials fallen around classifier, then impact on the whirlpool cavity's scaleboard together, then will be rebounded and impact on the top of the whirlpool cavity, then changes its direction and goes down, forms continual material layers with the materials shot from the impeller. Therefore some materials will be impacted, crusher, milled twice or more times in the whirlpool cavity, then crushed materials will be excluded through the bottom discharging hole. This can from a closed circulation through the circular classifier system; in general, materials can be crushed into 20 mesh through thrice circulation. Airflow self-circulation in the whirlpool cavity can eliminate the dust pollution well.
