Production Principle and Advantages of Sand Making Machine
Jul.26, 2021
Sand making machine is the key fine shaping equipment in the process of industrial sand making. Due to high efficiency, good shaping effect, stable operation, investment cost saving, energy saving, environmental protection and other reasons, it is widely used in various stone factories and concentrators. And no matter want to buy good equipment or want to better operation equipment, must first understand how the sand machine works, therefore, this paper will be a detailed analysis of the sand machine working principle and production process, let you have a more clear understanding of the sand machine.
Sand production unit into the structure
Sand making machine is mainly composed of eight parts, such as feed, feeder, vortex crushing chamber, impeller experience, spindle assembly, base drive device and motor.
Technical principle of sand making machine
At present, most of the new type of sand making machine is hydraulic drive and automatic discharge combined with stone breaking technology, it is based on the traditional sand making principle according to the customer's actual use of the site and operating conditions of innovation, very suitable for the domestic sand market, is also the most economic and practical sand making technology.
Operation principle and production process of sand making machine
System sand machine began to work, to be broken material by the inlet into the crushing chamber, the powder feeder split into 2 parts, part into the high-speed rotating impeller, its drive the rapid acceleration, top speed to baidu acceleration of gravity, then at the speed of 60-70 - m/s from three uniform flow passage of impeller ejected out, first with powder feeder free-falling impact crushing materials, and then hit with vortex cavity lining material and be rebound material layer, inclined upward shocks to the top of the vortex chamber, change direction, inclined downward movement, and the impeller passage of the material together. In this way, each material in the crushing cavity are at least two or even more times the probability of collision, friction and grinding and broken. The material crushed to the appropriate size is discharged from the bottom discharge port of the sand-making machine.
New material into the hopper after, after the center of the feed opening into the high speed rotating rotor, by its full speed and emission mouth throw again, first with the rebound after the free-falling part of material impact, then hit together around crushing cavity back piece, be rebound to the bottom, after the deflection downward movement, and emitted from the impeller material impact to form a continuous material, suitable for granular materials were finally discharge sand making machine.
New sand machine principle advantage
The new type sand machine crushing technology adopts the combination of imported high quality alloy forging head instead of the traditional integral hammer head and square impact block, which makes the head not only hard and tough, but also has excellent high temperature resistance. The principle of the new sand making machine improves the original working process, making the whole process more rigorous and reasonable, not only improving the equipment efficiency and finished product quality, but also saving electricity. In the whole process of making sand, materials collide with each other, grind and break, and do not contact with metal parts directly, which reduces the possibility of materials being polluted and deteriorated, and prolongs the service life of the equipment. And the improvement of the inside of the broken chamber, also cleverly make the airflow can self-circulation, reduce the probability of dust pollution, more environmental protection.
