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. Girth gear is fixed on shell, which driven mating gear, gearbox and motor, which are fixed on heavy drive base. NSI Equipments Pvt. Ltd. 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.

Cylindrical Ball Mill is an efficient tool for grinding materials like ores, chemicals, ceramic raw materials, paints etc. into fine powder or fine paste by grinding in a wet way. The Ball Mill operates by rotating a cylinder with grinding balls like steel, CI, ceramic and pebble balls as grinding media. Material fed through the mill is crushed by impact and grounded by attrition between the balls and also the internal cascading effect reduces the material in to a fine powder. Ball Mills usually have liners inside which are replaceable when they wear. Liners will be of wave shape which key the ball charge in to the shell and prevent the slippage. The rotation of the powder mixer is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter is, the slower the rotation will be. Ball Mills are generally used to grind material ¼" and finer, down to the particle size of 20 - 75 microns. To achieve reasonable efficiency, the ball mills are to be operated in a closed system, with oversize particles continuously being re-circulated back to the mill and to be reduced.

Types :
  • Cylindrical Single / Multi compartment with classifier and without classifier.

The efficiency of the early stages of grinding in a Closed Circuit Ball Mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then are being separated, and the coarse part being returned to the mill inlet. The proportion of the mill-exit material returned to the inlet may vary from 10-30% when ordinary cement is being ground, to 85-95% for extremely fine cement products. It is important for system efficiency that the minimum amount of material of finished-product fineness is returned to the inlet. Modern separators are capable of making a very precise size "cut" and contribute significantly to the reduction of energy consumption, and have the additional advantage that they cool both the product and the returned material, thus minimizing overheating.

Features
  • Ball mill can be provided in MS/SS/Alloy Material with or without rubber lining.
  • Jacketed arrangement for heating or cooling applications.
  • Custom - designed to suit your requirements.
  • Stable performance and easy installation.
  • Easy maintenance and operation.
  • Counterbalance is directly opposite to man-hole opening.
  • Heavy support stand is provided.
  • Replaceable liners. (On request).

Operational Advantage
  • Uniform quality throughout of the entire batch, batch after batch.
  • Fineness accurately controlled by operating time, mechanical regulators being unnecessary.
  • Ultimate fineness is possible, less than 1 micron.
  • No workman's attention required while Mills is running. No skilled help needed at any time.
  • Combined grinding & mixing accomplished most efficiently without loss of time.
  • Equally suited for grinding both wet & dry products.

The Conical Type Ball Mill is most efficient when compare with cylindrical mill. Classification and circulation within the mill is the principle of operation for the conical mill. In a cylindrical mill most of the work is accomplished in only a portion of the mill cylinder length and the end corners are in effective. In conical ball mill it is maximum utilization.
