According to the "Cambodian Minerals Law", mining in Cambodia is divided into individual mining and industrial mining. Individual mining means that the local residents in the mining area carry out manual mining on their own land, and it must be less than 7 people. No mechanical equipment and explosives are allowed. The depth is not allowed to exceed 20 meters. The purpose is to help people improve their lives. The mining certificate is issued by the mineral bureau of the province where it is located and is valid for one year. Industrial mining is issued by the Ministry of Mines and Energy. It is divided into exploration licenses and mining licenses. Only companies with certain funds and technologies are eligible to obtain them. At present, most companies only have exploration licenses. Fees for small mining farms Individual mining requires buying land, or renting land, and then buying sand making and sand washing equipment. Generally, a small sand and gravel plant costs 80,000 to 200,000 US dollars. The establishment of a sand washing plant must require legal procedures. Recently, a team…

With the development of the economy, the world's demand for sand and gravel continues to increase. The river gravel washing plant designed by LZZG acts in different sand making environments. Cobblestone sand production line generally consists of vibrating feeder, crusher, sand making machine, belt conveyor, circular vibrating screen, sand washing machine, dewatering screen, and other equipment. Pebble crushing and washing plant Directly mined stone or produced sand contains more impurities, which is not conducive to sales. Therefore, many cobblestone sand production lines will be equipped with sand washing machine equipment. Under normal circumstances, the vibratory screening equipment already has some functions in the soil, without the need for sand washing equipment. However, if gravel aggregates with high cleanliness requirements are required, it is often necessary to equip the sand washing machine or bucket wheel to type sand.

Although lignite is low in mining cost, it is usually only used on site because of its high water content and low energy density, which is not suitable for transportation or trade. In addition, with the slowdown in China's consumption growth, coupled with the vigorous development of US shale oil, the international coal market price is lower, which also makes the situation of relatively high-cost hard coal power plants relatively prosperous. Vibrating screen can be used in Lignite quality improvement lignite coal vibrating screen c has high moisture and ash content, low calorific value, easy weathering in the air, and is not conducive to long-distance transportation. When used directly as a fuel, the combustion efficiency is low, and the greenhouse gas emissions are high and the pollution is serious, which has been greatly limited for a long time. The upgrading of lignite refers to the reduction of moisture in lignite by thermophysical or thermochemical methods, and the increase of the calorific value of the product, which is convenient for transportation, high heat utilization efficiency and low pollution. In Germany, coal-fired…

Mining trommel screen is screening equipment developed for power plants, coking plants, building materials, metallurgy, chemical industry, mining, and other industries with large processing capacity, high screening efficiency and no plugging. Trommel screen overcomes the circular vibrating screen. And the linear vibrating screen has the problem of screen blockage when screening wet materials, which improves the output and reliability of the screening system. Mine drum screen working principle Australia high quality trommel screen parameters After the broken stone enters the drum, the material is sieved by the centrifugal force of the rotation of the drum and the elimination effect. The stone with large grain size flows forward along with the inclination of the drum and is gradually screened out through the screen of different meshes, and the granularity is not large. After the stone material is sieved out, it falls into the respective funnels. The materials are screened out one by one through different mesh screens and then dropped into the belt conveyor through the funnel and sent to the finished material yard. Trommel screen for occasions: 1. Stone yard…
