FLSmidth ESSA® LM Series

Born in the crucible of the Australian mining industry the Essa® line of laboratory pulverizing mills are the most powerful, robust and versatile systems of their type available.Ideal for ores, slags and industrial minerals, the  LM series of mills are designed to handle a range of sample sizes from 50g to 4.8kg depending on your application and each can pulverize samples to <75um in approximately 3 minutes. These mills are designed integrated safety features including an emergency stop button, lid safety switch, pneumatic bowl clamps and system for safely handling heavy grinding vessels.
  • Range of models from Introductory to high volume
  • Accommodates 50g to 4.8kg samples
  • Pulverize typical samples to 95% <75µm  in 3 minutes
  • Powerful- 1kW to 4kW motors
  • Versatile- each can mill acomodate multiple sizes of vessels

LM2 PULVERISING MILL

 

Vibratory mill for rapidly preparing up to 1.8kg of material for analysis (with the extra power of a 2.2KW shaft drive)

The vibratory head of the model LM2 is driven by a universal shaft powered by vee-belts from a standard, stationary (non-vibrating) 2.2kW electric motor. This drive arrangement delivers more power to the grinding bowl and optimises motor life (because it is not exposed to direct vibration as happens in traditional integral vibratory motor driven mills). The mill also differs from traditional integral vibratory motor driven mills). The mill also differs from traditional mills because of it’s ability to be fitted with a unique 800cc, 1000cc or 2000cc single puck type grinding bowl in addition to any standard size of ring and roller grinding bowl.

The model LM2 is well suited to high volume mineral laboratories regularly preparing large samples in the unique Essa single puck style of bowl or to any laboratory remote from the specialised repair services typically required for integral vibratory motor driven mills.


 

LM5 PULVERISING MILL

 

Vibratory mill for rapidly preparing up to 5.0kg of material for analysis (with the  power of a 4.0KW shaft drive)


 LM5 mill is used for pulverising ores, minerals, soils, metallurgical samples, ceramics, aggregates, chemicals and similar particulates. It finds particular application in mineral laboratories needing to prepare larger, more representative samples. Typically, samples of approximately 3 to 3.5 kg mass can be ground to 90 to 95% minus 75 micron, while larger samples up to approximately 4 to 5 kg can be reduced to approximately 0.5 to 0.8 mm particle size (all subject to the physical characteristics of the material. and the condition of the grinding elements). Grinding time will be approximately 5 to 8 minutes
 The vibratory platform of the model LM5 is driven by a universal shaft powered by vee-belts from a standard, stationary (non-vibrating) 4 kW electric motor. This arrangement delivers the power required to drive the large 5 kg nominal capacity grinding bowl integrated in to the head of the mill. The drive motor is inherently protected from direct vibrational loads. The design of the bowl is based on Labtech Essa internationally patented concept of a single, solid “flying saucer” shaped puck operating in a curved bottom bowl. Only the puck is removed from the bowl during routine operation. A pneumatically actuated “MILLMATE™” hoist is fitted as standard to assist in lifting and lowering the puck. The bowl is filled and emptied manually. Residue is vacuumed from the bowl. A vacuum gun is supplied as standard with each mill for connection to the customer’s dust extraction system.
