Product Description

Continuous Sand Mill

With the help of our professionals, we are able to manufacture and supply our clients a high grade range of Continuous Sand Mill. It is designed using supreme quality raw materials as per the set industry norms under the directions of our experienced professionals. The offered Continuous Sand Mill is precisely designed to ensure its effective performance and durability. It is also checked on various parameters of quality and is extensively used by our esteemed clients owing to its smooth functioning and longer service life.

Specifications:

  • In sand grinding (pigment dispersion) process a homogeneous mixture of a pigment / vehicle slurry (Mill base) is pumped through a cylindrical bank of sand, which is being subjected to intense agitation

  • During passage through the agitated sand / media zone

  • The mill base is caught and ground between sand / media a strong shearing action which effects the dispersion of pigment into vehicle

  • On emerging from the active sand zone, the dispersed mill base over flows through an exit screen sized to permit free flow through of pigment dispersion while holding back sand / media particles

1) Vertical Mills

In the original Sand Mill the screen holding back the sand media at the top of the mill was an open type. While closed type Sand & Bead Mills have a submerged type   of   screen   or  seperator.  The  can  be   provided  with  conventional  or mechanical tightly sealed to permit operation under pressure and also to accept high viscosity products.

2) Horizontal Mills

In this design, grinding chamber in horizontal one instead of vertical / upright position.

In the event of the unit being stopped, the horizontal position enables it to be restarted without difficulty; regardless of product being processed its viscosity or type and size of grinding media being used. Thus the use of steel balls/ other high-density media, which may be contraindicated in a vertical mill, because of ball settlement to the bottom, is no problem with horizontal design. The ball media remain uniformly distributed along with length of horizontal Mill at all times, while in new closed type design, maximum utilization is mode of grinding chamber ( more than 80 to 85% of the grinding chamber is filled with grinding media) and by creating more than one pass in a single grinding chamber by means innovative designs of agitator. So horizontal mills are compact and utilized for finer grinding using miniature high density Beads and special screens for media separation.
 
3) Basket Mill
 
Basket Mill is batch operation.
 
Basket Mill are suitable for dispersing of low and medium viscosity products of the Paint, Ink, Coating, Cosmetic and allied process industry.
 
Principle of working is almost similar to the principle of working of high-speed dispersion. Basket Mill is comprising of grinding chamber made of cylindrical shell (jacketed or non-jacketed) with perforated  / screened bottom end and open or screened / perforated top cover.  The product is circulated by pumping / dispersing impeller Positioned on mill shaft under grinding chamber or above grinding chamber, sucks the product through the grinding zone filled with small Grinding media. The grinding media is accelerated by wear resistant grinding discs in grinding chamber.
 
Basket Mill is submersible milling machine allows to charge materials and process there all in one tank and one simple operation. The Basket Mill allows  a greater amount of material to flow through the grinding chamber more offend resulting in narrower particle size distribution and stronger pigment strength in a shorter time.
 
4) Vibration Mill
 
Operating principle: Capital under the state of high frequency vibration of shocker or (vibration motor ) with high speed, grinding medias (rods, sticks & balls) in grinding cavity launch strongly, rotate quickly and revolve with low speed, making feed materials impacted, rubbed and sheared strongly, as a result of  superfine particles distributed evenly.
 
Perfomance & Features
Suitable for hard and soft materials with mohs’ hardness compared to Ball Mill, Air stream Mill and Impacting Mill. It has low investment cost, low energy consumption, simple flow, high efficiency and reasonable price. Particle size can be changed by adjusting quantities of feed materials, amplitude of vibration and grinding media’s grades. To form series connections with classifier to get products with narrower size of distribution. Grinding media’s and scale board are made of high manganese steel, high cadmium steel, stainless steel.
 
5) Jar Mill
 
Space saving long roll Jar Mills are designed specifically for applications were space is at premium. Available in single and multiple tier models roll lengths available are 36”, 48”, 72”
 
Features
rolls mounted in ball bearing pillow blocks.
Rolls are 2.1/ 2” in diameters and are made of long wearing, oil, solvent and chemical resistant, neoprene rubber, bleeds off static electricity generated by rotating roll.
Free turning ball bearing jar stops mounted at each of the drive rolls assures jars remains on rolls.
Three position lateral spacing adjustment of idler roll, simple and quick to install, allows mill to handle all standard sizes or round containers from 2.1/ 2” x 15” diameter. They keep Jars separated positioned exactly. Jar positioners made of long wearing polyurethane are also available.
 
6) Pebble Mills - (Batch Type)
 
Pebble Mills are lined with different type of suitable lining bricks and utilizes Pebbles or balls as grinding media. It is ideal milling machine for wet and dry milling, where iron is an un-acceptable contaminant to the process. This Mills are employed for dispersion and size reduction of variety of materials used in paint and chemical process industries. They are provided with different linings like burrs tone (silica), alumina. Steatite, ceramic, porcelain, urethane rubber etc. as per the process requirements.
 
7) Steel Ball Mills - (Batch Type)
 
This is batch type Mills can be used for dry as well as liquid grinding. Designed from 2 to 10 feet diameter and can be jacked for cooling or heating. The rugged design result in simple operation. Low maintenance and consistant results. Mill can be provided with variety of drive mechanisms for either wet or dry grinding are amid center turned for alignment and offer machined mounting pads for precision gear mounting. Manufactured with abrasion resistant steel an rugged structural support.
 
8) Countineous Ball Mill (Steel Lined / Brick / Stone Lined)
 
Ball Mill is an efficient machine for grinding many materials in to fine powder Ball Mill or Tube Mills are barrel shaped having more length of shell than Diameter, rotating at specific speed for optimum milling effect. These operate by introducing the material to be milled in to rotating drum / barrel which contains a grinding medium. ( e.g. steel balls or rods or pebbles, ceramic balls) and material is ground (wet or dry) by attrition through the tumbling action of the Mill. Capital slow rotational speeds combined with simple and robust construction make them ideal for grinding hard and abrasive materials where continuity of service law maintenance and minimum down time are essential. They are provided with different linings materials inside Mill Shell as per the process requirements. Continuous Mill are fed at one end of the Mill and discharged at the other Mill end.
