Grinding Equipment

GREENFIELD batch type ball mill is working as batch type operation. Adequate size, shape and qty Grinding media is placed inside rotary drum from inlet port. Material can be fed from inlet connection provided in shell. All ports need to close before start rotating rotary drum. Fed material rotates with rotary drum. Grinding media rotate and dropped in side and reduce particle size. Mixing and grinding operation being done simultaneously when drum rotates. Mill is to be stop after completion of batch and remove material from outlet port.

Batch Type Ball Mill is operated as batch type. It is useful for wet or dry powder grinding as well as homogenously mix more than one material. Additives can be added for homogenously mixed during batch. It is for grinding Dyes, Ceramics, Pigment, minerals etc.

Heavy duty, continuous type ball mill is with three compartment and screen. Replaceable Liners are fixed inside entire mill.  Liners material and shape is selected based on material to be grind. Input material is fed in two primary grinding compartments. Large diameter balls for reduce particle size are laying inside first compartment. Material comes into second compartment for further grinding. Small size Balls are laying inside second compartment. Material comes into third for fine grinding. Smaller size media are laying inside third compartment for fine grinding. Diaphragms may place to regulate material level and control retention time. Material is feed and discharged through hollow trunnion at opposite end. Accessories like air classifier, cyclone, blower, return air circuit or dust collector can also be placed for close loop system. Two tiers fixed on both end of mill, which are rotate on four rollers. Rollers are fixed on support and oil immersed.  Mill rotates on four roller and two tiers. Girth gear is fixed on shell, which driven mating gear, gearbox and motor, which are fixed on heavy drive base.

GREENFIELD Continuous Ball Mill is useful for grinding coarse feed to get fine powder in single continuous operation. It is for grinding Ceramics, Cement, Pencil, Paint, Chemical, Ink, Marble, Coal, minerals, Ferro Alloys etc.

Pulverization is done by continuous impact of rotating hammers against liners. Raw material feed in rotary feeder from inlet hopper and spills into the grinding chamber. Strong hammering breaks lumps into small particles. At the same time air stream blowing through the Pelletizing Equipment Manufacturer carries the ground material towards outlet. Whizzer classifier doesn’t allow oversize particles to pass and returned them into the grinding chamber. They are re-grind and reduced up-to acceptable size. Fan is working for convey particles passed from Whizzer and send it to cyclone collector. Three-way connection Cyclone & dust collector (fabric type) provides clear air to the mill and keeps entire operation free from dust too.

 A tube mill is a type of grinder used to grind and blend bulk material into nano size using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell. The nanostructure size can be varied by varying the number and size of balls, the material used for the balls, the material used for the surface of the cylinder, the rotation speed, and the choice of material to be milled. Tube mills are commonly used for crushing and grinding the materials into an extremely fine form. The tube mill contains a hollow cylindrical shell that rotates about its axis. This cylinder is filled with balls of very small size that are made of stainless steel or rubber to the material contained in it. Tube mills are classified as attritor, horizontal, planetary, high energy, or shaker.
