With the development of infrastructure projects, the demand for sand and gravel is increasing, the exploitation of natural sand is excessive, the exploitation is limited by the state, and the production of machine-made sand is in short supply. Therefore, the machine-made sand market has developed well in recent years, and investing in large sand and gravel plants is a good choice. How much is the price of a set of large environmental protection machine-made sand equipment? Let's give you a detailed explanation:
What is used for large-scale environmental protection machine-made sand equipment?
The processing of stone into machine-made sand generally needs to go through three main processes: coarse crushing, medium fine crushing and sand making. The machine-made sand equipment used is jaw crusher, cone crusher / impact crusher and sand making machine, and then sand washing machine is needed for cleaning. The equipment is described in detail below:
1. Large jaw crusher (coarse crushing equipment).
Capacity: 1-2200t / h, feed ≤ 1500mm, discharge 10-350mm.
The vanguard of sand and stone processing relies on the extrusion of two jaw plates to roughly crush the stones. The crushing cavity is deep, and the materials begin to crush above the crushing cavity, so as to improve the crushing efficiency. The discharge particle size can be adjusted freely. There are PE, German version, European version and other models to choose from.
2. Large impact crusher / cone crusher (medium and fine crushing equipment).
Counterattack breaking: capacity 30-800t / h, feed ≤ 800mm.
Cone breaking capacity: 12-2181t / h, feed ≤ 560mm, discharge 6-54mm.
Both are medium and fine crushing equipment, which can directly produce stones of 12, 13, 24 and other specifications. The applicable materials are different. The impact crusher is suitable for processing medium and low hardness materials such as limestone, coal gangue and construction waste. The cone crusher has a slightly stronger crushing capacity, and is more suitable for processing high hardness materials such as granite, basalt, pebble and quartz.
3. Large sand making machine (sand making equipment).
Capacity: 50-585t / h, feeding ≤ 55mm, discharging 0-5mm.
The key equipment of machine-made sand processing, the crushing principle of the combination of stone beating stone and stone beating iron, makes it have the dual functions of sand making and shaping. The finished machine-made sand has better particle shape, less powder content, deep cavity impeller, automatic circulation inside vortex cavity, strong sealing, no dust overflow and more environmental protection in production.
4. Large sand washer (cleaning equipment).
The sand processed by the sand making machine also contains some impurities such as stone powder and soil. After cleaning with the sand washing machine, clean high-quality machine-made sand can be obtained, which sells better. It can be seen that the role of the sand washing machine in machine-made sand processing is also more important.
In addition to the equipment mentioned above, the machine-made sand production line also needs auxiliary equipment such as feeder, vibrating screen, belt conveyor and dust collector. The price of a set of large-scale environmental protection machine-made sand equipment ranges from 500000 to 200000. The specific depends on the equipment selection and output demand.
