River pebbles are currently an important raw material in the sand and gravel industry. The sales price of machine-made sand produced has risen from US110/ton to US118/ton. According to market research statistics, the price of sand and gravel will only increase and will not decrease with the development of the infrastructure industry. It can be said that the “investment prospects” are bright. If you want to invest in a complete set of equipment for river pebble crushing, the price of the equipment is a prerequisite for investment. This article tells you how to choose the right sand-making equipment for a set of 500 tons of river pebbles per hour, and how can the price be less than US2200,000.
Under normal circumstances, the configuration of a sand production line must be：
Feeder + jaw crusher + impact crusher + impact sand making machine + vibrating screen + transmission belt (if necessary, it can be equipped with a sand washing machine)
The entire assembly line is cumbersome and the investment cost is high, at least 300,000 US dollars or more. According to the hardness and particle size of river pebbles, we can rationally use the impact crusher and impact sand making machine to replace the impact crusher with a single-cylinder cone crusher that can achieve the dual effects of crushing and sand making. Not only does it reduce the investment in equipment and reduce the occupied area of the site, the performance of the advanced cone crusher has brought unexpected production results to customers. The details of the entire configuration are as follows：
Model ZSW600*130 vibrating feeder + PE900*1200 jaw crusher +Sc315 single cylinder cone crusher +4YK2460 vibrating screening machine (two sets) + several transmission belts (reasonable matching according to the size of the site)
Production details and “market quotation” of a full set of equipment for crushing 500 tons of river pebbles per hour
According to the matching information of the above-mentioned production line, the particle size of the first stage of the crushing feed can reach 700mm, and the second stage of the fine crushing discharge range is below 16mm. The two vibrating screening machines can screen out four different particle sizes, 0-5mm, 5-10mm, 10-20mm, 20-40mm, which are used as raw materials for different industries.
The ”innovative" equipment combination achieves a small investment and a large return on the premise of meeting customer production needs. The market price of this complete equipment production line with an hourly output of 500 tons of river pebble crushing is about US2200,000. Site construction, labor and labor services, transportation of raw materials, various taxes and other expenses are not included here, because the prices in each region are different. US2200,000 is very cheap for the market, but it should also be noted that the right manufacturer can ensure the quality of the equipment, and later maintenance is also very important.
