At present, natural sand and gravel resources are increasingly scarce. Using crushers and sand making machines to make a large number of useless stones into various specifications of sand is an effective way to fill the gap in the gravel market. River pebbles are hard and rich in resources, and are ideal materials for sand making. Compared with other stone materials, river pebbles are small in size and do not necessarily require a jaw crusher for coarse crushing. They can be directly fed into a cone crusher or impact crusher for medium and fine crushing. So, is it better to use a cone crusher or a impact crusher for river pebble fine crushing? Below, let's analyze the characteristics of these two devices together.
1. Cone crusher
The cone crusher adopts the principle of laminated crushing, which has the characteristics of large crushing force and high compressive strength. In addition, its wearing parts are made of high-quality high-manganese steel, which is strong and wear-resistant, and is very suitable for processing river pebbles. In addition, after technological improvement, the current cone crusher is highly intelligent, which can realize overload protection and iron-pass protection during the crushing process, and can be monitored in real time, safe and efficient, and ensures reliable operation of the equipment.
The impact crusher adopts the principle of impact crushing, and the finished product is in the shape of a cube and the quality is quite good. By adjusting the gap between the rotor and the counterattack plate, the particle size of the stone can be controlled to effectively meet the different needs of users. However, because the rotor and impact plate are used to complete the crushing operation, the wear rate of wearing parts is high, and the operating cost will be higher than that of the cone crusher.
In general, the initial investment of the cone crusher is high, and the operating cost is low; the finished particle shape produced by the impact crusher is excellent, and the initial investment is not high. The hard characteristics of river pebbles will increase the maintenance cost of replacing the wearing parts later, and users can make reasonable choices according to their own needs. If you want to better avoid investment risks, you must pay special attention to the purchase of crushing equipment. Only by choosing the right crushing equipment can the production line be highly efficient in the later stage, and then there will be high-yield and high-quality finished sand. Here is an introduction to the aspects that need to be paid attention to when choosing a river pebble crusher:
1. Try to shop around and inspect the equipment at the production base of the river pebble sand making machine manufacturer. Only by comparing a few more can you choose the better equipment;
2. Try to choose a strong and large-scale river pebble sand making machine manufacturer, and choose a manufacturer with higher cost performance among manufacturers of the same type and scale;
3. If the investment funds are limited, you can consider buying in areas where there are many river pebble sand making machine manufacturers, such as Henan. The local equipment where the manufacturers gather is more competitive, and the price will be relatively more favorable;
4. Choose direct-selling manufacturers as much as possible. Direct-selling manufacturers have no middlemen to earn the difference when selling. The prices of equipment are all ex-factory prices, so the quotation is relatively low;
5. When choosing river pebble sand making machine equipment, as far as possible to the manufacturer's sand production site inspection, to understand the use of sand making equipment.
