Our company has the ability to design and manufacture any drying unit with productivity in the range from 0.1 tons per hour to 40 tons of fertilizers per hour . If higher productivity is required, our company is ready to offer modular complexes for drying mineral fertilizers with a capacity of 80 tons per hour to 400 tons per hour .
FEATURES OF OUR DRYING EQUIPMENT:
Depending on the type of mineral fertilizers, their properties and moisture content, various drying units are used for drying. The most common drying units in the chemical industry and in particular in the production of mineral fertilizers are fluidized bed dryers. More details about it can be found in the section - fluidized bed dryer. The drum dryer for mineral fertilizers is also widely used. Also, in some cases, our company can offer aerodynamic dryers for mineral fertilizers, belt dryers .
A drying unit for drying mineral fertilizers must be aggregated with a heat generator operating either on gaseous fuel (natural gas, propane-butane mixture), or on liquid (diesel fuel, fuel oil, various synthetic boiler / furnace fuels, water-coal fuel), or on solid ( wood-burning furnaces, coal furnaces, multi-fuel (operating both on pellets, briquettes from wood raw materials, agricultural raw materials, and on wood chips, wood, coal - brown, anthracite, coals of grades D and G), installations for pulverized coal injection).
The most easy to maintain and technologically advanced heat generators are natural gas. They can be fully automated and do not require constant monitoring.
The only drawback is the cost of natural gas in Ukraine. The cost of drying is 1.5-3 times higher than when working on solid fuels or liquid (synthetic furnace fuels, pyrolysis products of tires, oils). 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 will be a heat generator operating on briquettes from sunflower husk and also on brown coal (pieces of 20-100mm). However, they have significant disadvantages.
IMPORTANT:
So, for example, all solid fuel 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. You also need a permanent warehouse for firewood with a week's supply, if you do not have a nearby permanent source of 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. 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 advisable to install a heat generator running on diesel fuel or natural gas and not have any extra hassle.
Also, in addition to the heat generator, for the operation of the drying unit, a smoke exhauster is needed , which ensures the suction of the necessary air for combustion or heating, its passage through the drying unit, a cyclone and the evacuation of moisture evaporated from the mineral substance. For each capacity in tons per hour, taking into account the humidity at the inlet and outlet of the drying unit, the rheological properties of mineral fertilizers, porosity, etc., a smoke exhauster is specially calculated, designed and manufactured with the required parameters.
The third necessary element for the correct management of the drying process of mineral fertilizers is the presence of a dust-precipitating cyclone . Mineral fertilizers are a valuable and at the same time often hazardous product and therefore require dust cleaning systems. The cyclone parameters depend on the performance of the drying unit, 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.
Drying equipment warranty - 24 months .
After the end of the warranty - discount service.
