7 ways to help you choose vsi sand making machine in good quality
As an advanced vsi-sand-making-machine, in local or abroad, the vertical shaft impact crusher(vsi-sand-making-machine), has a wide range of market demands, many machine suppliers emerge accordingly. But unfortunately, it is still not easy to find a satisfying crusher machine from such many so-called “best” suppliers. There is an old Chinese saying, buy cheap and waste your money. Let’s sharpen our vigilance to uncover the tricks that selling at a very low price even below the normal producing cost.
1 Feeder hopper
The left one is from by jointing
The right one is from by model punching press, shaped at a time, is more durable.
2 Cone feeder and disc feeder
The left one is cone shape feeder inlet.
The right one is disc shape feeder inlet, can do the conversion among the type of central feed and fall feed quickly, thus reduce the adjustment time.
3 Butt ends
There are two types of the butt end of vsi sand making machine, one is integrated type( as shown on the left), another is upper and lower combination type( showing in the right). the latter one is a combination of two pieces, can prevent the vertical shaft from wear, efficiently by replacing the worn out plate, in addition, save the cost by more than 30%.
4 Guard board
Guard board also divides into integration type and combination type, as shown in the right, exchange using the upper and lower board can increase the coefficient of utilization, prolong the service life more than 48%.
5 Impact block
There are two kinds of impact block, square shape, and diamond shape, diamond shape block can avoid the material damaging the vertical shaft effectively, prolong the inner plate service life. Besides, it has better wear resistant performance.
6 Crushing cavity
The high-quality vsi-sand-making-machine has the optimal design of structure and angle, can reduce the flow resistance, thus increasing the production efficiency greatly.
The rotor as the core crushing part, influence the sand shape and amount significantly, large, deep cavity make the production capacity increased greatly.
7 Material, function, technology, etc.
For example, the key parts of the machine are made of first-class alloy material; the bearings and electric motor are equipped with the international well-known brand; Japan imported hydraulic device, quench process principal axis, etc.
JXSC MINE supply you with the real sand making machine without tricks.
