Spice Grinding Mill

Fine spice grinding mill is specially designed for fine grinding of various spices. A perfect design of pneumatic conveying system ensures a dust free and cool operation which is very important for spice, thereby retaining vital properties like color, taste, aroma, flavour, oil content etc. 
This spice grinding machine can handle various spices like chillies, turmeric, coriander, mixed spices (for curry powder), dehydrated onions, garlic, ginger, black pepper etc. It also grinds foodstuff & various ayurvedic herbs & roots. To maintain the spice properties to its optimum level, a two stage-grinding operation is recommended. First stage coarse grinding with a 3 to 5mm screen followed by second stage line grinding through a 0.5/0.8 mm screen. Either the operations can be done in the same machine by changing the screen or two separate machines can be used for coarse and fine grinding simultaneously. 
Working Principle 
The machine chamber consists of swinging hammers side liners & top liners. As the material is fed into the machine through the feeding hopper, it gets pulverized between the swinging hammers revolving at a very high speed and the liners. The perforated screen fitted in the lower part of the chamber regulates the fineness of the pulverized material depending upon its hole diameter. Once the material passes through the screen, it is sucked by a blower unit mounted by the side of grinding mill, which passes through the pipe, cyclone collector and finally discharged through the two-way discharge valve. The air along with the very fine powder will go into the dust collector, where the material will be trapped into the filter bags and the air will be let out. The attachment of the dust collector ensures dust free operation. The free circulation of air into the grinding mill keeps the chamber cool, thus retaining important properties of spices like taste, flavour and colour.
