General stationary sand making production line: feeder + jaw crusher + impact crusher/cone crusher + sand making machine + sand washing machine + vibrating screen + belt conveyor + centralized electronic control composition, which needs to be fixed the site requires piling and cannot be moved. Such a stone production line has a high output (the output can be dozens of tons to thousands of tons per hour), but it is not adaptable to the site and cannot be moved back and forth. Of course, this is also suitable for those stone processing sites that are close to the raw materials, the supply of raw materials is large and continuous, the output requirements are high, and the production area is large. How to configure a high-quality and environmentally friendly sand production line? You can choose equipment suitable for your own production according to your own production needs. Below, we will reveal the secrets of purchasing equipment skills and help you choose suitable crushing equipment.
1. Coarse crushing is generally open-circuit production. For processing incoming materials from the stockyard, the commonly used first-level crushing equipment is a jaw crusher. This equipment is a more commonly used rough crushing equipment. It takes the lead in the production line. It can crush various hardness stones. It has a large feed port, strong crushing capacity, large crushing ratio, simple structure, convenient operation, and random configuration of motor power appropriate, the energy consumption of the system is low.
2. Medium and fine crushing generally adopts closed circuit technology. Commonly used equipment includes impact crusher and cone crusher. The latter is divided into single-cylinder hydraulic cone crusher and multi-cylinder hydraulic cone crusher.
1) The impact crushing product has good grain shape, low one-time investment, and is widely used, but it is only suitable for crushing rocks with medium hardness and low abrasiveness. Otherwise, the operating cost will greatly increase and the economy will decrease. At present, there are hard rock counterattack crushers on the market, but the operating cost is still relatively high. For hard rock crushing, cone crushers are better.
2) Due to different types of cone crushers, their crushing power and crushing ratio are different. The current trend is to develop hydraulic cone crushers. In terms of comparison between multi-cylinder and single-cylinder, the former has higher overall performance. However, the choice of single cylinder or multi-cylinder in the entire process flow depends on the layout of the entire process. If the crushing ratio is large, multi-cylinder hydraulic cone crusher can be used to reduce the number of crushing sections and reduce the system investment. The pin-flake content is generally equal below 18%. For crushing hard rock, multi-cylinder hydraulic cone crusher can also be used. For crushing general rock, single-cylinder hydraulic cone crusher can be used.
3. Sand making machine (vertical impact crusher, composite crusher, vertical shaft impact crusher) is currently widely used sand making equipment, with high production efficiency, good particle shape, low operating cost, and can play a role in shaping. The stone is finely crushed and sand-made, with large throughput, and both plastic and sand-making functions. The finished product has excellent grain shape, deep cavity treatment, less dust, and good environmental protection and energy saving effects.
4. The commonly used sand washing and recycling equipment include bucket wheel sand washing machine, spiral sand washing machine, fine sand recovery device, etc.
5. Auxiliary equipment selection includes feeding, screening, etc.
1) Feeding equipment. In general, the feeding equipment is divided into plate feeder and wave roller feeder, electromagnetic vibrating feeder, reciprocating feeder and vibrating screen feeder. According to the difference in the conveying output of the parent rock, the vibrating screening feeder is usually widely used. Its advantages are sufficient feed volume, high soil content and large water content. At the same time, it can also use the integration of the screening function and the conveying and feeding function. Eliminate impurities and realize the production of machine-made sand and gravel.
2) Vibrating screen. Commonly used vibrating screens are divided into circular vibrating screens and linear vibrating screens. Generally speaking, the circular vibrating screen is used for the classification of large and medium-sized materials; the linear vibrating screen is used for the classification of medium and fine-grained materials, and can also be used for dewatering. Therefore, what kind of screen to choose to make it efficient and low in cost are all issues that must be considered.
