Micro Pulverizer
This machine consists of a high speed rotor, revolving inside a stationery cylindrical grinding chamber. The shaft is horizontal and the "T” shaped hammers/beaters are pivoted onto a series of rotor discs. These discs are key-fitted on the horizontal shaft. Thus, when the shaft rotates, the hammers are allowed to swing freely on its pivots, allowing the hammers to take its own position due to the centrifugal action.
The particles of feed entering the grinding zone are sucked into the chamber and are subjected to a grinding force due to the high speed pivoted hammers. The chamber is serrated on the inner surface acting as a stationary anvil plate against which the particles are repeatedly thrown and are broken into pieces. The particle thus reflected by the serrated chamber are subjected to a hammering action by the rotating beaters and are pushed through the grate or screen which covers the discharge opening.
Based on the speed of rotation, the type of hammers and the screen employed, different grades of fineness of the product are achievable.
The rate of feed of the product also plays an important role in determining the final mesh size of the pulveriser output.
The discharge of
the pulverised product is from the bottom of the grinding chamber which
has provision for an ‘air-balloon’ for trapping very fine
particles escaping along with the air.
All contact parts are made of SS 304/SS 316 material.
