Vibratory Cup Mills - VCM
Insmart vibratory cup mills offer the full benefits of program controlled grinding processes for the preparation of samples for elemental analysis and phase analysis. Controlled by programmable controllers, it results in a reproducibility in sample preparation and consequently brings optimum analysis results. Vibratory cup mills are suitable for the grinding of even harder minerals like Slags, Ferro alloys and other materials upto a fineness of 38 microns. The high speed of the drive motor and the gyratory motion of imbalance mass enables even hard material to be ground within a very short time. It is meant for most efficient lab scale pulverizing operation in mining, metallurgy, cement, steel, aluminium, ceramics industries and the ground product is ideal for instrumental analysis using x-ray fluorescence analysis. The equipment performs fine grinding of dry as well as wet laboratory samples with equal ease. Ideal for exceptionally rapid grinding of extremely hard, Brittle and soft materials down to laboratory fineness.
Working Principal of Vibratory Cup Mill: The Vibratory Cup Mill brings about an impact of the hammer and/or the ring (grinding media) on the grinding materials inside the bowl this causes the size reduction. The collision intensity depends on heaviness and differential speed of the grinding media. The imbalance mass in the motor drive creates vigorous motion of the bowl and the grinding media. The equipment attains maximum impact from the very start of the grinding to attain most optimal and repeatable results in few minutes. Grinding bowls are used for a range of applications, with capacities of 50 ml, 150 ml. Hardened steel, Stainless steel and Tungsten carbide bowls are designed for easy handling where the operator simply clamps the bowls and starts the grinding operation. Insmart vibratory cup mills are fully insulated against noise and have safety cut-outs for operator protection. The dust and noise pollution at the workplace is therefore substantially reduced. Insmart vibratory cup mills are high-quality, precision engineering products with compact dimensions and are therefore ideally suited for QC lab scale grinding operations. The design of the machines corresponds to the current accident prevention guidelines.
Highlights of Grinding Environment:
150 ml bowl is fed with input material size of upto 8 mm, suitable for a variety of sample types.
Exceedingly quick grinding (30 seconds to 3 mins).
Fast grinding achieves the desired particle size in the range of 100 to 325 mesh.
Material of Construction: Grinding cup and rings are made from hardened steel, Tungsten Carbide, Agate or stainless Steel (depending upon material to be ground) provides improved analytical results as it gives reduced sample contamination.
Easily operable pulverizing set.
Dry & wet pulverizing.
VCM Main Features:
Programmable Grinding: Grinding cycle time can be completely preseted. Thus, required fineness is achieved even under intermittent power supply conditions.
Programmable cycle time setting is possible to suite the material fineness.
Changeability in Bowl location plate: No change of bowl location plate is required and bowl sets of 50ml to 250 ml can be placed on the same bowl location plate.
Four Bowl Simultaneous Grinding: In case of multiple material grinding requirements, 4 Bowl VCM provides the facility of grinding 4 different materials at the same time. This option is available only with 50 ml bowls.
Safety Features:Over Load Tripping: In order to counter power surges Motor drive is provided with additional protection through OLR- trip. 4 Pole MCB with reliable circuit breaker is also provided for additional machine safety during power surges. Door sensor: Material Grinding is done in an enclosure fitted with a door to load & retrieve the material. Thus, grinding is performed in a protected area. In case the door is opened while machine is in operation, the machine is provided with suitable sensors that stop the machine in order to avoid any possible accident.
Fine grinding within minutes.
For high speed grinding of minerals, ores with extremely high repeatability.
Detachable grinding bowl set for better cleaning. Superior quality bowls to eliminate cross- contamination during grinding.
Independent precise time control system to achieve the desired material fineness for different materials.
Flexibility in Grinding Output
Range of size reduction from -8 mm to 38 microns is achieved by faster and more efficient grinding(material dependent)
Programmable cycle time setting is possible to suit the material fineness
