As a professional sand making equipment, the vertical shaft impact crusher (sand making machine) has a wide range of market demands, but the uneven product quality makes the price of the equipment vary, even several times. So why is the price difference so big? There are many reasons, and the details are the key!
1. The design difference of the feed hopper
The hopper on the left adopts the welding hemming process, and the hopper on the right adopts the stamping process, which is formed at one time. The latter has a higher technical level and is more durable, and the price will increase accordingly.
2. The difference between bulk cone or bulk tray
On the left is the bulk material cone, and on the right is the bulk material tray. The latter can quickly realize the conversion between center feeding and waterfall feeding, reducing downtime adjustment time and improving efficiency.
The height of the two can be adjusted to affect the feeding method. Take the bulk material cone as an example:
High-less material in the center, more material in the waterfall;
Low-the center feed is more, the waterfall feed is less,
In actual production, most users use 70% central feed, 30% waterfall feed, or complete central feed.
3. The difference in the structure of the throwing head
The sand making machine throwing heads on the market have two structures, one is integrated (as shown on the left), the other is combined up and down (as shown on the right), and the latter is a combination of two large and small throwing heads. , Only need to replace the worn out throwing head part, effectively prevent it from damaging the vertical plate after it is worn out, and can reduce the use cost by more than 30%.
4. The difference in the structure of the peripheral guard plate
The peripheral guard plate composed of the upper and lower two parts can be turned up and down after partial wear, which improves the material utilization rate, prolongs the service life by more than 48%, and saves the cost of parts.
5. The difference in the shape of the impact block
The impact block of the sand making machine has two types: a square structure and a diamond structure. The latter is more popular with users, because the diamond-shaped combined impact block can avoid material impact damage to the vertical board. It can also be used in turns while improving its own wear resistance. , Which not only improves the utilization rate of materials, but also effectively protects the life of the inner peripheral guard plate of the sand making machine.
6. Design differences of crushing cavity
The high-quality sand making machine has the best launch port and smooth internal curve design, which reduces the flow resistance of the material, greatly improves the passing capacity of the material, and thereby improves the production efficiency of sand making.
In addition, the rotor is an important crushing component of the sand making machine, and its design affects the amount of sand and the type of sand and gravel. The deep cavity rotor greatly improves the ability to handle materials.
7. Equipment material, configuration and process differences
For example, the key parts of the machine are made of first-class alloy materials, the bearings are selected from international leading brands such as Japan, Sweden, and the United States, equipped with high-protection motors, imported from Japan with hydraulic cover opening devices, and the world’s advanced light oil anti-leakage devices are used. The frame made by steel plate bending and hot rivet technology, after quenching, the complex spindle processing technology is annealed…
The material and technology of the equipment affect the quality of the product and also affect the price of the product.
