Sand making machine, also known as impact crusher and sand making machine, crushes various large rocks into construction sand required in various fields. It is suitable for soft, medium and high-hard ore materials with a hardness not higher than 320Pa. Mining machinery and equipment technology continues to develop, and the requirements for equipment are becoming more and more stringent. There have been several generations of upgrades and many types. What are the specific types of sand making machines? The following has been sorted out.

What types of sand making machines are there?
There are currently about 9 types of sand making machines on the market, including impact sand making machines (HX, VSI, HVI, VSI-A7), compound sand making machines, roller sand making machines, fine crushers, and hammer sand making machines. Sand machines and impact crushing sand making machines and other equipment, the following are several commonly used types of sand making machines.
1. Impact sand making machine
It mainly adopts the working methods of "rock against stone" and "stone against iron", coupled with the deep cavity impeller design and increased throughput, the finished product is relatively thin and has the shaping function. It is equipped with a combined throwing head, only the worn parts need to be replaced, and the cycle is completed at the same time. The guard plate can be turned up and down to extend the service life. In addition, the air flow inside the vortex chamber is self-circulating, plus a pulse dust collector and a noise eliminator, which meet environmental protection requirements. The lubrication method can be selected, and the bearing chamber is modularly designed with thin oil type and grease type. Fully interchangeable.
2. Compound sand making machine
It is optimized and designed by combining domestic and foreign fine crushing technology. Due to its three-dimensional design and small footprint, it is suitable for crushing various medium-hard ores. It uses the working principle of stone on stone to have a large crushing ratio, no screen bar settings, and a large mud content. The material should not be clogged, the moisture content can reach about 8%, and the iron pollution is minimal.
3. Double roller sand making machine
Crushing is carried out by squeezing between two rollers. The driving device is driven by two electric motors, which has higher production efficiency. It can process various types of medium and high hardness materials. The finished sand and gravel aggregates are in the shape of cubes, needles and flakes, with low content and no internal content. The cracks and discharge granularity are fine, which improves the production quality and efficiency, especially in the coal industry, and has very good effects.
4. Hammer sand making machine
Modular design allows conversion between coarse, medium and fine crushing by changing the cavity type. The process is simplified, the floor space is small, and the operating cost is reduced. At the same time, high wear-resistant materials are used for the hammer head, grate plate and impact plate to ensure a long service life. It is longer, has its own sealing properties, and is equipped with dust-proof and silencer devices, which solves the problems of large dust and dust leakage from the machine body.
