1. cobblestone machine-made sand cost analysis: 1. Reasonable design of sand production line is the key. Reasonable design of sand production line is the key to investment. Different manufacturers have different equipment models, configurations, materials selection and output, and their quotations are also different. The quotation of equipment on the market now ranges from tens of thousands to hundreds of thousands. When purchasing sand-making equipment, we should reasonably combine different sand-making equipment according to our own production demand, output and scale. Reasonable selection of sand making equipment can reduce the investment cost.
2. Pre-audit process is very important for basic investment. Site rent, power labor cost, sand-making material cost and transportation cost are all basic investments for starting a sand-making plant, and these expenses are all essential. Because the sand production line involves a lot of expenses, the specific expenses also depend on the user's site scale, production demand, equipment purchase and so on.
Second, cobblestone machine-made sand equipment Generally speaking, the production of machine-made sand in gravel factory is mainly divided into five processes: feeding, crushing, sand making, screening and sand washing. The equipment required for these five processes is as follows:
1. Vibrating feeder: also known as feeder, it is used to quantitatively, uniformly and continuously send granular and massive materials from the silo to the receiving device in the production process.
2. Crusher: used to crush various materials, used as coarse crusher and medium crusher in mining, infrastructure and building materials departments, with small occupation space and large crushing ratio.
3. Sand making machine: Sand making machine is the core equipment of the whole sand and gravel production line, which is suitable for the crushing and molding of materials. Generally used for three-stage crushing of stone production line, the principle of "striking iron with stone" and "striking stone with stone" is adopted to achieve good molding effect.
4. Vibrating screen: it is responsible for screening out gravel with different particle sizes to form different sand and gravel products, so as to improve production efficiency.
5. Three-in-one sand washer: The sand washer is an important equipment for sand washing, which can effectively remove the soil and stone powder covering the sand surface and improve the quality of sand, thus meeting the needs of users for materials. At the same time, it also has the function of tailings recovery, high cleanliness, environmental protection and energy saving.
