I. Introducing complete sets of equipment for sand and gravel production line 1. Feeding: the vibrating feeder quantitatively and directionally conveys materials from the bin crusher for preliminary crushing treatment;
2. Crushing: Jaw crusher is responsible for coarse crushing. Coarse crushing the bulk materials with a jaw crusher, and the particle size meets the requirements of secondary crushing, and then sending them to an impact crusher or a cone crusher for medium crushing;
3. Sand making: Different types of sand making machines have different working principles. The common types and models are HVI sand maker and VSI sand maker, and users can choose and match them according to actual needs.
4. Screening: The screening treatment of vibrating screen can effectively check whether the completion of each step is qualified, and select qualified stone materials for secondary processing until the crushing is qualified.
5. Cleaning: Sand washer can remove impurities and coating dust from sand and gravel, which is an effective method to improve the quality of finished products.
Second, the price of a complete set of sand production line equipment The price of a complete set of sand making machines ranges from hundreds of thousands to millions. The size of equipment, materials used, market demand and other factors will affect the price of sand making equipment.
There are great differences between different types and models of sand making equipment. Large-scale sand-making equipment has large production capacity and high production efficiency, so the price is higher. Material will also affect the price of sand making machine equipment, because the quality of material will affect the performance of sand making machine and the quality of machine-made sand. If the equipment is made of good material, the sand maker produced will have higher quality, better performance, longer service life and higher price.
The market demand is mainly manifested in the market demand for sand making equipment. Nowadays, natural sand aggregate is scarce, and more and more users turn their attention to machine-made sand. The production of machine-made sand can not be separated from the processing of sand-making equipment. If the market demand for sand-making equipment is high, but there are few equipments circulating in the market, the price of sand-making equipment will be higher; On the contrary, the market demand is not large, but when there are more circulating equipment in the market, the price of sand making equipment is lower.
