Long heavy sand dewatering recycling machine is how to improve the quality of sand
The dehydration type sand recovery machine has two functions of dehydration and recovery. The main function of dehydration is the finished sand of the sand washing machine directly enters into the dewatering sieve for two cleaning, classification and dehydration. While the recovery function is wastewater discharged sand washing machine (also known as mud, sand and water mixture) into the cleaning tank, via vacuum high-pressure pump to separator, separation and extraction of sediment collected fine sand, fine sand spit into the sink by dehydration sieve dehydration, other impurity clearance separator overflow, enters the return water tank discharge.
The use of the dewatering sand recovery machine greatly reduces the content of water, mud and impurities in the sand, and improves the quality of the sand. At the same time, the sand is recovered, and the output of sand is increased and the objective economic benefits for the users are raised. In addition, the full recovery of fine sand also plays a role in protecting the environment. Therefore, has been the vast number of sand washing customer recognition and love.
Of course, the quality of concrete can be improved by using iron tailings, composite sand and recovered sand, which is a better use of tailings. (1) iron ore tailings recycling machine and sand collocation can fully meet the requirements of fine aggregate concrete, can completely replace river sand, but need to be adjusted according to the proportion of different strength grade of different construction technology. (2) the river sand quality fluctuations, the stability of iron ore tailings sand and fine sand recovery system is far better than the river sand, for the use of polycarboxylate admixture enterprises is more conducive to the quality control of concrete, concrete to reduce volatility. (3) from the perspective of the cost of iron ore tailings, sand and recycling costs will be lower than the river sand, achieve the purpose of reducing costs, and in some areas, the use of collocation can enjoy tax preferential policies to return the considerable economic benefit. (4) in the test and production of fine sand recovered from iron tailings ore and sand recovery machine, it is necessary to control the material source. High quality stone powder is very beneficial to the strength and workability of concrete. (5) try to use hanging pulp is good, less bleeding cement. Improving the paste property of concrete paste. To make the fine sand recycling machine really achieve the effect we want must be in accordance with the following operation, can recovery of high-quality sand: when starting sand recycling machine, must ensure that the equipment is started, in the empty load condition if the equipment overload, start, it is easy to cause the increase of motor load, caused by burning the problem of motor. After the sand recovery machine is smoothly and stably started, the feed can be fed. The amount of feed shall be uniform in the length of the rotor. Otherwise, it will speed up the local wear of the hammer and the counter plate.
