In the process of machine-made sand production, sand making is one of the key technologies to improve the production and efficiency of machine-made sand. Many sand and gravel plants mainly use fine crushing jaw crushers, fine crushing or grinding equipment for pre-grinding before grinding. These crushing equipment will severely wear parts, resulting in high maintenance costs, time-consuming, laborious and low efficiency. The vertical shaft impact type sand making machine better overcomes the above shortcomings and realizes the production requirements of machine-made sand.
The advantages of vertical shaft impact sand making machine:
1. The main shaft of the machine is driven by a transmission device to make the rotor rotate at high speed. The material is sprayed into the crushing cavity through strong centrifugal effect, and the liner is impacted at high speed without hammering. At the same time, due to the strong vortex generated by the rotor in the crushing chamber, the material violently collides and rubs in the airflow, so that the material is refined and broken.
2. The vertical shaft impact sand making machine adopts different lubrication system designs, which reduces the need for frequent lubrication, and is equipped with an oil quantity alarm system, which provides a strong guarantee for the safe operation of the entire equipment.
3. The airflow design of the powder making room is novel, no dust removal device is required, and there will be no dust pollution to the external environment.
Based on the above advantages, the vertical shaft impact sand making machine has been on the market for more than three years. However, due to its low investment, high efficiency, and high benefits, it is still chosen by more and more companies, and it has become the most popular equipment for "grinding instead of crushing".
