For the selection of sand and gravel production line equipment, specific conditions must be analyzed, and a sand and gravel production line that meets customer expectations should be designed according to the specific conditions of the production site, material characteristics, product size, and market demand. Only in this way can the sand and gravel production line achieve the best crushing effect and production efficiency. The sand production line includes five modules: crushing, sand making, transportation, screening, and sand washing.
1. Crushing: The machine responsible for crushing includes a jaw crusher, which is mainly responsible for the coarse crushing of materials; the impact crusher/cone crusher is mainly responsible for the medium and fine crushing of materials, generally behind the jaw crusher.
2. Sand making: The sand making machine is a device that crushes the crushed stone to a certain extent again, and the particle size of the finished product is generally below 5mm.
3. Screening: Vibrating screen is important equipment responsible for grading materials of different sizes after coarse, medium and fine crushing.
4. Sand washing: The sand washing machine not only cleans the crushed stone, but also dewaters and classifies the finished crushed stone.
5. Transportation: The machine responsible for conveying in the production line is a belt conveyor, which can not only be used for material conveying in the production line, but also serves as a link.
In actual production, the main function of any ore crushing production line is to crush and process various ore, sand and gravel to a reasonable size and shape. Since there is much equipment that forms an ore crushing production line, their interactions are intertwined. Therefore, the configuration of a scientific production line is by no means a mere rigid set. The production line must be tailored according to the material conditions, output requirements, and finished product requirements. The following are three commonly used equipment configuration schemes:
1. Feeder + jaw crusher + impact crusher + sand making machine + vibrating screen, suitable for sand and gravel plants with medium and low hardness. Its advantages are high yield and good particle size.
2. Feeder + jaw crusher + cone crusher + sand making machine + vibrating screen, suitable for sand and gravel plants with extra hard raw materials (such as granite, river pebbles, silica, etc.), characterized by high output, less equipment wear, and more durable , the market price is high.
3. Feeder + hammer crushing + impact crushing + sand making machine + vibrating screen, suitable for sand and gravel plants with medium and low hardness (limestone, bluestone, dolomite), etc., with simple process flow and small area , The hammer can be formed at one time, and the cost is low.
In addition to the equipment cost of the sand and gravel production line, what other specific costs are there?
1. Early-stage expenditures: such as the recruitment and training of relevant personnel, equipment packaging, calibration, and certification.
2. Transportation, installation and relocation costs: the cost of equipment transportation, installation and relocation, plus the sum of the costs of removal, relocation and clearance. The installation costs include the cost of steel and concrete materials used in the foundation, labor costs, and costs for hoisting equipment.
3. Later operating costs: including but not limited to operating costs such as lubrication, repair, maintenance, and power consumption.
