Detailed Description for Mini Pulverizer

Technically sound designing of mini pulverizer makes it a perfect pulverizer for a crushing target of up to 15 to 80 kilogram per hour. It takes less installation space than normal pulverizer machines and has steel mould body. This ensures unmatched durability and little maintenance. The advanced working methodologies of this pulverizer ensure superior quality of ground material. The mini pulverizer comprises of a heavy duty mild steel / stainless steel body, which comprises of a feeding hopper, with a feed regulator slide. The pulverizer body is inlaid with a delivery trough attached at the bottom, with a delivery trough attached at the discharged end. The rotor and beater are mounted on shaft, running in ball bearing housing at a speed of 4500-6000 RPM the whole unit is mounted on a strong steel stand.

Operating principal of mini pulverizer :-

The flow of material from the feeding hopper is regulating by means of side handle easily to suit the load. Rotor with four cutters runs in anti-clockwise direction. The beater pass just beneath the ratchet teeth liner fitted inside the top half of the crushing chamber, leaving a gap of 1/8" (3.175 mm) between the liner teeth and the tips of the rotating beater. This cuts the material caught between the liner teeth like a sword with a scissors action at a high speed rotations. After the required size reduction, the material will pass through the screen fitted inside the lower discharge end of the pulverizing chamber. No sieving is required, as the appropriate size screen fitted will not allow coarser material to pass through. The air generated in the crushing chamber forces the powder to pass through the screen fitted at the bottom discharge end of the crushing chamber, into a filter attached to the delivery trough below. (when crushing wet-pulpy materials, the balloon should not be use).

 

Servicing guidelines of mini pulverizer

 Open the cover of chamber all pulverizing parts cleaned with a brush in couple of minute and the pulverizer is ready for next crushing. If required, the grinding chamber can also be wash with water. Remove the cotton balloon and the screen, close the cover tightly and start the grinder. Now pour a bucket or two of water into the hopper. The grinding parts will be flushed with the water and cleaned. Continue running the machine for a few more minutes as the draft of the fresh air sucked into the grinder will dry it. The beater when worm out removed and reserved by removing the cur clip lock holding to the rotor pins. When both the edges are worm out, they sharpened on an emery stone, to be use as new. In addition, when completely warn out, replaced the equal weight and refitted.

 Rugged construction of mini pulverizer

 Mini pulveriser is made from specially selected materials. The beater are interchangeable and reversible thus, the pulveriser will last for a life time with minimum replacement of parts. Mini pulverizer is made from cast iron body. Grinding chamber lined with serrated wear plates, which protects the body from wear and tear. Grinding done by a set of swinging four numbers inter changeable and reversible beater on a balanced rotor which is fitted on a shaft. Shaft is fixed with a suitable deep groove ball bearings which is continuously lubricated by oil (company supplying the machine without oil) instead of rubber oil seals metal seals are used for avoiding friction and maintenance, which will occur due to the use of rubber seals. A screen classifier forms the lower half of the grinding chamber.

Typical application of mini pulverizer

The mini pulverisers are widely used for grinding of dry/wet spices, chili, fresh ginger, garlic, fresh fruits, and vegetables. These pulverizer machines can also be used as a fruit finisher. The mini pulverizer can also be used for the following dry applications like agricultural chemicals, broken biscuits (hi-fat/low fat), custard powder, coffee, charcoal, dals, dyes and pigments, fillers, henna leaves, herbs, leaves and roots instant foods insecticides and pesticides, kaolin molding powders, pharmaceuticals, plastics, poultry feed and marine feed, resins, sugar (biscuit grade/icing grade), separates, tea etc.

 Outstanding features of mini pulverizer

Unique and reliable design The mini pulveriser series machines are highly effective as well as non-stop continuous pulverizing process.

Compact size Dust free operation Ideal for dry crushing Increased production leading to faster return on the investments Very easy to operate thus do not required skilled labor.
