The Ultra Fine mill is a screnless pulverizer used to grind soft to medium hard material into very fine powder upto fineness of 300to 400 mesh BSS. This system has built in water jacket to prevent high temperature rise at the time of grinding . The grinding takes place due to attrition between high speed wear resistant tips and liners on both the side along with turbo (jet) effect. The material is discharged through annular gap plate through which the flow of material is controlled. The capacity ranges from 40 kg/hr to 300 kg/hr.

The hammer mill is the most effective pulverizer used for size reduction of various application viz. Spices, Chemicals, Minerals, Pharmaceuticals, Herbs & Roots, etc. It can be used for wide range of material ranging from friable, non - friable, fibrous, etc. Thegrinding takes place between the high-speed swinging hammers and top/side liners. Once the particle size reduces to that of the perforated screen at the bottom, it will be discharged through the hopper. The fineness achievable in this system will be 15 to 60 mesh BSS (depensing on the physical properties of the material). The capacity ranges from 50 kg/hr to 1500 kg/hr.

The Air Swept Mill is a screenless pulverizer which is used for micro grinding of brittle, fibrous, soft to medium hard material. In this system, the grinding takes place between the serrated liners and high speed hammers. The material is then sucked by the blowerbefore which there will be whizzer classifier which allows only the micro powder to pass through thereby trapping the oversized material. This system is best suited for grinding of turmeric fingers, grains, etc. The capacity ranges from 40 kg/hr to 2 Ton/hr.

The Pin Mill is used for fine grinding of soft to semi solid material. The heat generation in this system at the time of grinding is very low compared to other pulverizers. This ensures prevention of vital properties like aroma, taste, etc. This grinding system is used in pulverizing, wet grinding, deagglomeration, etc. The material is centrally fed and grinding takes place in between high speed rotors consisting of pins and a stationary stator. The discharge takes place through perforated screen. The capacity ranges from 100 kg/hr to 2Ton/hr.

The Micro Pulverizer is used to grind soft to medium hard material into fine powder. This system is widely used for applications like spices, pharmaceuticals, dyes, icing sugar, etc. The grinding takes place between high-speed stirrup type hammers and serrated liner.The material is discharged through sieve. The fineness achievable in this system ranges from 50 to 200 mesh BSS.The capacity ranges from 50 kg/hr to 1500 kg/hr.

The Chopper machine is designed to crush the material into small pieces or granules. This system is most efficient where there is requirement of granules, tbc, flakes, etc ot irregular shape but uniform size. The system is designed in such a way that there is no heat generation and very less powder content as compared to other pulverizer. In this machine, there are 2 fixed blades each on both sides and rotating blades on the shaft between which the material is being cut / crushed. This system is widely used for Teacut products and for crushed chilly for pizza toppings (Chilly flakes). Some other applications for which the machine is used are ayurvedic herbs, onion flakes, granulations for food colors, etc. The capacity ranges from 40 to 50 kg/hr to 2 Ton/hr.
