Drum dryer for limestone.

Our company has the ability to design and manufacture, at the request of the customer, a drying drum for drying limestone with a capacity of 0.5 tons per hour to 30 tons per hour. The initial moisture content can be from 15-18%. If higher productivity is required, our company is ready to offer modular limestone drying complexes with a capacity of 60 tons per hour to 500 tons of limestone per hour .

The most optimal particle size distribution of limestone for drying is 0 - 20 mm. It is this coarseness that allows you to quickly and efficiently, with minimal cost, dry a large amount of wet limestone.


Drying drums for drying limestone 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), and on  solid fuels (wood-burning furnaces, coal furnaces, pulverized coal injection installations).


Heat generators operating on natural gas are the easiest to maintain and technologically advanced. They are fully automated and do not require constant monitoring. Their only drawback is the cost of natural gas in Ukraine. The cost of drying is noticeably higher than when working on solid fuels or liquid. The most significant savings can be achieved using solid fuel heat generators. Among them, the best price / cost ratio *, the pulverized coal-fired heat generator has the manufacturability. And the most economically profitable is a heat generator operating on briquettes from sunflower husk and also on brown coal.


However, they have significant disadvantages.

1. 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 1.0 - 1.5 MW, the required amount of firewood is 25-37 cubic meters. per day, which is equivalent to 1 truck (however, it should be noted that if briquettes from sunflower husks or lumpy brown coal are used as fuel, then the required number of briquettes for a heat generator with a capacity of 1.0 - 1.5 MW will be only 5-8 bags MKR (big bag)). 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.

2. 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 limestone. For each capacity in tons per hour, taking into account humidity at the inlet and outlet of the drying drum, rheological properties of limestone, porosity, etc., a smoke exhauster is specially calculated, designed and manufactured with the required parameters.

3. The third necessary element for the correct operation of the limestone drying process is the presence of a dust-precipitating cyclone . Dry limestone is a very 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.

The drum has a 24 month warranty . At the end of the guarantee - sales service discounts.
