Product Details:

RIECO Air Classifier Mill (ACM) is an air classifying mill with integrated grinding, classifying, conveying, and collecting operations for achieving ultra-fine grinding (up to 2 micron*) depending upon the nature of the product.

Air classifying Mill / Air classifier Mill (ACM) can be designed for grinding hygroscopic, heat sensitive and explosive materials in inert gas/ closed loop systems with dry chilled air. Our classifiers are engineered to consistently produce steep particle size distributions that are uniform and homogeneous.

Working Principle:
The material to be grinded is conveyed from the hopper to the grinding chamber by the variable feed screw mechanism. The grinding occurs when the product meets a pin or bar type rotor disc. As particles are reduced in size they are entrained by the Air stream which enters below the rotor and are carried up between the inner wall and shroud ring with baffles, the particles are then deflected by an air dispersion ring to the separator assembly. Acceptable product is drawn through the exhaust and is collected by a high efficiency bag filter. Oversize particles are carried downward by internal circulating air stream and return to Rotor for additional grinding.

Air Swept Mill (ASM) is a screenless Pulverizer mainly used for fine pulverizing of soft & medium hard dry materials. In ASM, the material enters in the grinding chamber & is beaten up by hammer lined up on the shaft with impact action. As the mill is screenless, the classifying action is performed by the specially designed wizards. Adjusting the wizards influence the fineness of the product. Moving wizard towards the hammer gives a coarse output and moving away from the hammer gives a fine output. Material is picked up by the induced draft blower unit and gets conveyed through the pneumatic conveying system to the Dust Collector. Depending on the application and client requirement additional features can be incorporated with Air swept.

For heat sensitive products, we facilitate water cooling jacket on mill to ensure grinding at ambient temperature. Air swept mill is used to grind materials like Turmeric, limestone, various minerals, chemicals, pigment, Ayurvedic Herbs & roots etc.

Phenol Formaldehyde Resins are prepared in special reaction vessels called kettles by reaction of phenol with formaldehyde in the presence of acidic or base catalyst at 120 °C. The product formed is liquid Phenol-formaldehyde, which is then collected, and air cooled in large trays beneath the kettles, thus the product obtained is rigid and brittle. This rigid product solidifies throughout the trays and needs to be broken manually. Further, we offer solutions for handling and fine grinding of dry phenolic resins.

Dry phenolic resins of 4-10 inches can be pre-cut in Heavy duty crusher to the size of 5mm and less with capacity a range from 500-2000 Kg/hr. Further, these pre-cut resins are formulated with hardener, binder, and fillers in our high efficiency pre-blenders (Ribbon blender) for homogenous mixing. Ribbon blenders are designed to achieve maximum efficiency at minimum power consumption. These homogenous mixtures are transferred further for fine grinding to the Air Classifying Mill (ACM). ACM helps in achieving uniform particle granulation with narrow bandwidth which is most suitable for phenolic resin application. ACM can be provided with Heat exchanger system for cool grinding to take care of the hygroscopic and heat sensitive nature of fine phenolic resin powder.

Roaster, as the name specifies is used to roast the material, usually for spices and food sector. In this operation the excess moisture is removed and the taste of the blend changes for direct application to food products, without further frying or roasting. Roasting reduces bacterial growth and increases the product life. As the heating is carried out by the indirect heating method, the aroma loss is low. It can be used for roasting various types of individual or mix spices products comprising Coriander, Fenugreek seeds, Fennel (Saunf), Bay leaf (Tej Patta) /Cinnamon, Cumin (Jeera), Sesame etc.

Roasters are Roasters cum Blenders with steel fabricated ribbons inside. It not only roasts but also blends (in case of zero heat application, it is used as a Blender). It uses thermic fluid and electric heater combination for its heat development and its retention purpose. The instrumentation available controls the highest temperature of the thermic fluid (250 Deg C). After reaching this high temperature, it stops further heating and only restarts once the prefixed user defined low temperature is reached.

The Spice Roasters are batch type machines and are supplied as a complete package consisting of process chamber, heating system, drive unit, & pre-wired control panel. Our specially designed spiral ribbons give the best Roasting results due to three-dimensional action. Thus, every particle comes equally in contact with the heating zone and is roasted equally. It is safe, have multiple aspect and definitely a preferred roasting device.

Operation:

• A thermic fluid is filled in the jackets of the roaster. This fluid is heated through electrical heaters to maximum temperature of about 250 Degree Celsius
• This fluid heats up slowly. However, after attaining maximum temperature, it retains the same for adequate period, providing enough time for the material to rotate, roast and blend simultaneously
• Once fully heated, it supports in roasting the entire material in short time, by avoiding burning of peripheral material
• A thermostat-based temperature and system controller is used to regulate the temperature in the thermic fluid.

Product Details:

The quality of powder coatings is influenced by many factors and the important amongst all is particle size distribution. High product quality requires a narrow particle size distribution with a pointy and well- defined top cut and low number of fine particles. The produced particle size distribution is influenced by material properties of the powder coatings and by the technology used for the powder coatings grinding system. The width of the particle size distribution also depends on the design and therefore the efficiency of the grinding system. Important factors include type of the mill to avoid over milling the type of grinding material, to achieve a high grinding intensity, optimized airflow conditions, and a highly efficient classification.

Powder Coating Process

Air Classifying Mill with automatic feeder system and cyclone collector & dust collection bag filter makes a complete system & grinds powder coatings most efficiently. Since powder coatings offer virtually a vast choice of various colors and textures, many new custom coatings start within the laboratory as small batches, which are sent to the customer for trial and approval. During this developmental stage, the coatings are usually prepared as a resinous sheet of fabric & flaky. The sheet is then broken into smaller pieces and ground in powder form, using mill so as to provide a fine powder with a particle size that is typically 80 microns and below. Air Classifying Mill is suitable for this purpose and has been the instrument of choice by powder coatings manufacturers.

Operation

AirThe material to be ground is fed to the mill through the suction feed with the help of rotary air lock valve then material proceeds to the grinding chamber where grinding action takes place (or size reduction) by impact and shearing forces between a rotor disc mounted with hammer sets and a multiple deflector liner. After the grinding, fine particles pass through the air classifier wheel where gradation takes place. Only the finer particles pass through rotating classifier wheel whereas coarse particles get retained to grinding section. Whole system works under the negative pressure system with the help of centrifugal fan located after the bag filter in series which generates required suction. 95 – 98% material is collected through Cyclone whereas remaining fine particles are collected in the Dust Collector with minimum production loss.

We manufacture Universal Mill for grinding different types of materials inside the same mill housing to desired fineness. This versatility is achieved by means of five different types of Rotor + Stator combinations for grinding a great variety of products. These ROTOR + STATOR combinations are mutually interchangeable, so that, if necessary, changeover to another desired type is conveniently possible. Due to this feature the machine is called Universal Mill. It is also commonly known as Pin Mill or BT Mill. The mills run at a peripheral speed and are perfectly balanced to avoid any possibility of vibration. They generate a strong air current to allow the products to be fed and not the mill under its own suction force as well as to convey the ground products to a distant collection point. They can also be combined with other machines into an appropriate system for fulfilling various requirements in practice

Operation:

• The material to milled is led out of the feed hopper by a mechanical feed dosing device into the feed inlet or suction spout of the mill. The rate of feed needs to be controlled for ensuring a uniform trickle feed so that uniform milled product is obtained without blocking or overloading the mill. Suitable controls are provided with the mill.
• In the feed inlet of the mill a strong permanent magnet can be provided to catch hold of any ferrous tramp matter. The feed material mixed with a quantity of air aspirated by the running of the mill rotor, enters the milling chamber near the central axis of the rotor. The material is hurled vigorously outwards toward the periphery of the rotor by centrifugal force and progressively reduced in size by the milling rotor till it reaches the circumferential sieve ring. After passing the sieve ring the milled powder has to be separated from the accompanying air.
• The degree of fineness achieved will depend on the nature of product, type rotor and the sieve ring fitted. It is also influenced by rate of feed, the quantity of air sucked into the mill with the feed and the peripheral speed of the rotor.
