The Lab Sand Mills or otherwise known as Batch Type Bead Mills for Lab Scale are considered to be one of the most competent grinding-dispersing systems or grinding mills. They are simple, cost effective and efficient machines and thus these are employed in numerous research laboratories worldwide. From decades, Renders India is primarily engaged in manufacturing and exporting high quality Lab Sand Mills. The performance and the quality of the SmartGrind Lab Sand Mills manufactured by Renders India has garnered immense accolades across several industries in India and overseas.

The Sand Mill or Batch Type Bead Mill consists of a stationary vertical grinding chamber which in turn contains the shaft and agitator discs. The chamber is filled with required volume of grinding media i.e. beads. The material is directly charged into the grinding chamber from the top of the chamber. The material or the batch to be processed is being aggressively agitated along with the beads. The necessary energy for dispersion and grinding is transmitted to the grinding beads by the agitator discs. The higher degree of collision between beads, agitator discs, materials and tank chamber inside the chamber brings about fine grinding effect. .The mill is run for a certain operating time based upon the process requirement.

Lab Sand Mill


Aimed to achieve higher degree of

  • Grinding
  • Dispersing
  • Designed for optimum particle size reduction our SmartGrind Lab Sand Mill reduces particle size upto 1 micron.
  • For laboratory scale, chamber configurations available range from 500 ml to 5 L.
  • SmartGrind Lab Sand Mills are manufactured with variety of materials of construction that may include Mild Steel (MS), Stainless Steel (SS) of all grades and several other materials to suit your process requirements.
  • Grinding media used are made up of stainless steel, zirconium oxide, tungsten carbide, ceramic, glass etc. Beads of appropriate size and shape are chosen to give best grinding and dispersing effect.
  • The chamber is jacketed for cooling or heating purpose and provisions of necessary inlet and outlet with nozzles bring about perfect process environment for the Lab Sand Mill.
  • Mechanical seals or any other appropriate seals are being employed as the sealing system as the sealing in Lab Sand Mills is one of the most vital parameter for their performance.
  • The SmartGrind machines generate unbelievably low noise during operation thus reducing the sound pollution.
  • Our SmartGrind Lab Sand Mills are well capable of handling low to high viscous materials, thus it proves to be very efficient in wet milling technologies.


  • Our precisely calculated torque, revolutions of shafts and agitator discs, shape and design of agitator discs, dimensions of chamber, type and material of construction of grinding media beads, sealing system etc. make our SmartGrind Lab Sand Mills give unmatched quality and superior performance.
  • A perfect operating speed ranging from 10 to 1440 revolutions per minute (RPM) to suit your requirement is achieved by combining of superior quality Motor, VFD (Variable Frequency Drive) and other electro-mechanical arrangements.
  • All our SmartGrind Lab Sand Mill models are safe, as we offer every product in certified explosion proof options.
  • The SmartGrind Lab Sand Mills may combine with smart features that include speed controller, temperature and pressure monitoring devices, programmable logic controller (PLC) ,HMI control panel, touch panels, limit switches, sensors, auto-valves and several other highly advanced features to make your entire set of machinery and process ‘smarter’.
  • Temperature control with the help of a temperature sensor and controller, which automatically stops the grinding motor when a set temperature is exceeded.
  • SmartGrind Lab Sand Mills are painted and coated superiorly for great aesthetic looks and long life span. A supreme finishing touch of the wetted parts i.e. buffing, polishing etc give the machines unmatched look.
  • Finished material discharge is through valves or tilting.



  • Our SmartGrind Lab Sand Mill is compact designed thus occupying very less space.
  • The SmartGrind Lab Sand Mills are very cost effective and energy efficient
  • Superior materials, components used to construct our SmartGrind Lab Sand Mills impart maximum durability with sturdy and robust characteristics.
