What kind of motor?
It is an EU stage V water cooled four cylinder dieselmotor driving a 42 kVA generator. The rotation speed is 1500 rpm, so it is both quiet and economic.
How do you change the screening media?
The upper deck is side tensioned and fastened by 4 bolts. The lower deck is end tensioned and fastened by 2 bolts only. The nose of the screen is foldable for even better access of the lower deck. It is possible to perform the swap as a single operator and after a few times it takes no more than 15 minutes.
What is the price of a new set of meshes?
Meshes for the upper deck normally cost 300-400 EUR. For the lower deck 250-300 EUR.
What if I only want to produce one size?
Only use the upper deck for sorting and leave the lower deck empty. The tensioning profiles in the bottom deck need to be fastened in order to prevent wear and tear, the tensioning profile in the rear needs to be removed from the screen box.
What is the feed-in-height of the hopper? What kind of loader is suitable?
The feed-in-height is 2.8 m and the reject grid is 3.0 m wide. A very suitable wheel loader is a Volvo L70, L90 or similar. It is absolutely possible to use a smaller loader, but a small access ramp will be needed.
Is a vibrating feeder suitable when producing top soil?
The vibrating feeder of the ECO3 is designed to handle even difficult material, as it operates with a more powerful movement and lower rotation speed than common vibrating feeders. The benefit of a vibrating feeder is the versatility, it can be used for almost any kind of material.
Is it possible to adjust the feeding speed?
Yes, the variable speed driver is controlled via the radio transmitter (also used for tipping of the reject grid).
What parts usually need to be replaced?
The ECO3 is a very robust plant featuring a lot of the same proven components as the larger Maskin Mekano plants. It is essential to retighten the screening media after a while to minimize the strain. If the filters and the oil of the motor are changed according to recommendations and the lubrication points are greased every 40th hour there is usually no need to replace any parts.
How many lubrication points are there? Can it be fitted with centralized lubrication?
It is possible to fit the ECO3 with centralized lubrication, but most customers chose not to since there are only 4 lubrication points that are very accessible and only need to be greased every 40th hour. To lubricate the bearings of the cylinders once every year is also recommended.
What is the weight of the machine?
12 tons as standard, in Sweden and most countries it can be transported with a standard hook-lift bogie truck.
What is the fuel consumption?
The ECO3 has a fuel consumption of only 3 l/h.
The machine is very quiet, how is that possible?
The rotation speed of the diesel generator is only 1500 rpm and it is also noise insulated. The screen box is mounted on a vibration damped frame which prevents the vibrations from the screen from transmitting to the chassis, this also contributes to the low noise impact.
How long is the set-up-time?
For transport mode the feeder is lowered and the conveyors folded, this is done hydraulically without any need for any manual handling. It is ready for transport in 5 minutes and ready for production in the same time.
And the capacity?
The ECO3 is suitable for a vast range of recycled material such as asphalt, concrete, landfill and so on, but also for building material and scrap and of course traditional sorting tasks. The capacity when producing top soil is 30-150 tones/h, depending on how moist the material is. For other materials the capacity is usually between 100-200 tones/h.
