Sand dryer
Drum dryer for sand.
Our company has the ability to design and manufacture, at the request of the customer, a drying drum for drying sand with a capacity of 1 ton per hour to 40 tons of sand per hour . If higher productivity is required, our company is ready to offer modular sand drying complexes with a capacity from 40 tons per hour to 500 tons per hour .
PECULIARITIES:
Our drying drums for drying sand can be aggregated with heat generators operating both on gaseous fuel (natural gas, propane-butane mixture), liquid (diesel fuel, fuel oil, various synthetic boiler / furnace fuels, coal-water fuel), solid (wood-burning furnaces, coal furnaces , installation of pulverized coal injection).
Heat generators operating on natural gas are the easiest to maintain and technologically advanced. They are fully automated and do not require constant monitoring. The only drawback is the cost of natural gas in Ukraine. The cost of drying is noticeably higher than when operating on solid fuels or liquid combustible products such as heating oil, liquid fractions of tire pyrolysis products, waste engine oils, etc.
The most significant savings can be achieved using solid fuel heat generators. Among them, the best price / cost ratio * technological effectiveness is possessed by a pulverized coal-fired heat generator .
And the most economical in terms of low cost of drying are heat generators operating on briquettes of sunflower husk and lumpy (25-100mm) brown coal. Due to the fact that briquettes have a stable calorie content, small and handy sizes, they are packed in big bags, they are more convenient and economical than firewood.
IMPORTANT:
However, they have significant disadvantages. So, for example, all heat generators require a stoker for timely fuel supply and ash removal. When using a wood-fired heat generator, it is necessary to constantly monitor the moisture content of the incoming firewood, otherwise the required thermal power for the drying process will be impossible. It also requires a permanent large warehouse for firewood and a firewood preparation area (unloading, sawing, sorting). For example, for a heat generator with a capacity of 1-1.5 MW, the required amount of firewood is 25-37 cubic meters. per day, which is equivalent to 1 truck. But a briquette from sunflower husk or brown coal for such a heat generator requires only 5.5-8.2 tons per day. Thus, it turns out that, depending on the wishes and needs of the customer, the type of heat generator used is not always obvious. Sometimes it is more expedient to install a heat generator that runs on diesel fuel, or on natural gas and not have unnecessary trouble.
Also, in addition to the heat generator, for the operation of the drying drum , a smoke exhauster is needed , which ensures the suction of the necessary air for combustion, its passage through the drying drum, cyclone and the evacuation of moisture evaporated from the sand. For each capacity in tons per hour, taking into account the moisture content of the sand, at the inlet and outlet of the drying drum, rheological properties of sand, porosity of sand, etc., a smoke exhauster with the required parameters is specially calculated, designed and manufactured.
The third necessary element for the correct management of the sand drying process is the presence of a dust-precipitating cyclone . Dry sand, especially for foundries or containing a large amount of silt and / or clay impurities, is a dusty material and therefore requires a dust deposition system. The cyclone parameters depend on the performance of the drying drum, the amount of moisture removed from the material, the type of heat generator. Therefore, in each individual case, depending on the configuration, we select the cyclones individually.
When buying equipment from our company we provide all the necessary documents - a data sheet, an operation manual, installation and aggregation schemes with feeding and unloading material. We also provide any feasible advisory assistance in the preparation of project documentation for coordination with government agencies.
