1, environmental protection cost and environmental protection is the direction of sand and gravel factory. Many governments require sand factories to meet environmental protection standards before putting into operation. Specific environmental protection measures include installing dust removal equipment, closing the production workshop, greening the surrounding environment and hardening the roads in the factory area.
2. Labor costs The production and management of the sand and gravel factory need to employ employees with professional skills, such as accountants, drivers, duty personnel, etc. , all belong to the software investment of sand and gravel factory.
3. Power cost The equipment in the gravel production line will consume electricity during operation. In general, the equipment technology and energy-saving effect produced by large sand manufacturers are better, which can save a lot of money in the long run.
4. Material consumption cost An important cost of the operating expenses of the molding sand production line is the consumption of wearing parts, which need to be replaced regularly. The cost of replacing wearing parts every year is a big expense in operating expenses. Therefore, many big-name product research and development will pay attention to the selection of vulnerable parts.
5. Sand-making equipment cost Vibrating feeder: In the sand and gravel production line, it can continuously and evenly feed the crushing machinery and roughly screen the materials.
Crusher: Crusher is used to crush ore materials with simple structure and good performance.
Sand making machine: suitable for crushing soft or medium hard and extremely hard ore materials with hardness not more than 320Pa. It is generally used for shaping and finely crushing the crushed materials of crusher.
Sand washer: it is mainly used to remove impurities (such as dust) from sand products. It can remove impurities covered on the sand surface, and at the same time destroy the water vapor layer covered on the sand particles, which is beneficial to dehydration and plays an effective role in sand washing.
Vibrating screen: Using the principle of vibrating motor to excite vibration, so as to achieve the purpose of screening.
Belt conveyor: conveying machine-made sand by continuous or intermittent movement of conveyor belt.
6. Civil engineering expenses The civil engineering and steel structure of the workshop and the sand-making equipment of the sand-gravel factory all need corresponding budget expenses.
