Pulveriser machine is used to reduce the size of material with fast grinding , up to super mesh level & at very economically. The machine has CI robust construction with standered heavy design to reduce size of different material. Also by lookgin at need of growing industry the same machine is also designed to comply with stringent GMP norms.
The machine in industry also known as micro mill, can be made customized way as per customer’s requirement. For heat sensitive products machine can be offered with air or water cooling arrangement.
For coarse to fine dry & wet grinding of all types of chemicals, coal, colours, cosmetics, food colours, fertilizers, medicine herbs, pharmaceuticals, paints, pigments, pesticides, spices etc.
PRINCIPLE OF PULVERISING
Pulverizer is compact, low cost, highly efficient grinding mill, capable of grinding variety of products from coarse to fine mesh size. Material to be pulverized is crushed between high speed moving beaters & serrated liner & by impact between rapidly moving beaters & the particle itself, the energy of the rapidly moving beaters dissipating itself into the particles being ground by virtue of their inertia, thus causing the particles size reduction.
The machine has swing hammer to cut the material with the help of lineat. At the bottom screen pass the material and if the material size is not reduced then material is brought again gfor grinding . the machine is working on the high RPM so material has to cut result ing very fine material up to micro or mesh as per requirement of end use can be set by speed of rotor and also by screen size.
SCREW FEEDING (Optional @Extra Cost )
Feeding Screw is powered by electric motor the material to be ground is fed to the grinding chambers in a uniform way by screw feeders. Feed screws are made in single & multiple types designed to convey the material from feed hopper to grinding chamber & at the same time act as a pre-crusher for reducing large soft mass of material to suitable size for the micro pulverizers. Screw feeding is provided with variable speed arrangement.
Gravity feeding can also be used to pulverize materials like sugar, salt or carbon as these types of material are extremely easy to grind & does not require screw feeding. Gravity feeding arrangement consists of a specially designed hopper with sliding valve, which conveys the material into the grinding chamber by gravity.
This are set of beaters revolving at high velocity in the chamber & beat in the materials as it enters from the screw feeders. These hammers are forged out of hardened material.
High speed revolving beaters pulverize the material against the rachet teeth liner into fine powder of desired mesh. The pulverized fine powder is pushed through the screen into the collecting bag by the air draft generated due to the centrifugal movement of the beaters.
The required coarse to fine mesh size of material is obtained by different types of screen. The particle size is not accomplished by the screens. They hold the material in the chamber until the particle is pulverized to the required size by the hammers and the liner.
Descharge of material after milling or grinding process from pulverize is carried out through Cyclone Separator to reduce the effect of dusting due to generated positive pressure mean while grinding.
Cleaning very easy as the interior of the grinding chamber is smoothly finished. It is possible to dismantle each part of the unit for easy & through cleaning & reassembling with the use of simple tools in no time. Alternatively for certain easy non sticky product this can also be cleaned through idle running of machine through compressed air.
