Product description Brand name and product description

The product is designed with same concept as any electrical mill, however, the 3-phase AC motor is connected directly to the grinding system, eliminating the need of conveyer belts, thus saving on energy which is lost due to friction. with a 3-pase AC motor which is connected directly to the grinding system. It does not require conveyer belt. The product has been discontinued by a new model.

Design specifications Component and Operation overview including power, portability, facility requirements, preventative maintenance and user training requirements

The Solar Milling Small-Scale system is supplied as a set with two different configurations available:

Option 1: Single Mill
1.) One Stone Mill machine, 1 Hp motor, and 500 mm stone.
2.) Photovoltaic Modules: 16 units of 100Wp Polycristalline Si.*
3.) Control panel to drive the stone mill.
4.) Electrical cables and accessories. Plug and play.
5.) Wooden box for mill transportation and user manual (English and French).
* Holder structure for solar modules to be made locally

Option 2: Twin Mills
1.) Two Stone Mill machines, 1 Hp motor each, and 500 mm stones.
2.) Photovoltaic Modules: 11 units of 250Wp Polycrystalline Si. *
3.) Control panel to drive the stone mills.
4.) Electrical cables and accessories. Plug and play.
5.) Wooden box for mills transportation and user manual (English and French).

The Stone Mill is based on pure granite 500 mm stones and equipped with standard three-phase asynchronous motor 230/400V 50 Hz.

Product schematics Design and assembly illustrations

The stone mill machine is connected to a control panel, which is powered by the photovoltaic modules through electrical cables and other accessories in a plug and play manner.
