Essa LM2 Pulverising Mill

From the iconic Essa® LM series, the LM2 is a bulletproof, reliable vibratory mill powered to rapidly prepare high volumes of mineral ore samples for analysis.

• Accepts bowls from 50 cc to 2000 cc for adaptability to a wide range of grinding applications and sample sizes whilst reducing contamination and sample losses. 
• User-friendly pneumatic bowl clamping for increased efficiency and reduced manual handling. 
• Easy to clean insulated cabinet with effective noise suppression measures. 
• Stationary 2.2 kW motor and drive shaft arrangement provides a reliable drive system and increased motor life. 
• Compact footprint for easy installation and efficient use of plant space. 
• Lid safety switch and emergency stop button for improved safety. 
• Mineral industry recognised standard used by most major commercial laboratories. 
• Available in many variable voltage options. 
• Detachable front access panel for simplified maintenance access.

Powerful and flexible operation 
With the power of a 2.2 kW driven shaft, this long-term tested and proven workhorse pulverising system rapidly prepares up to 1.6 kg of material for analysis, making it well suited to: 
• High volume mineral laboratories that regularly prepare large samples in the unique Essa single-disc style of bowl. 
• Any laboratory remote from the specialised repair services that are typically required for integral vibratory motor-driven mills. 

The ability to be fitted with a unique 800 cc, 1000 cc or 2000 cc single disc type grinding bowl, in addition to any standard size of ring and roller grinding bowl, makes it adaptable to a wide range of applications. Optional bowl materials include chrome steel, standard steel and tungsten carbide. The LM2 is used for pulverising ores, minerals, metallurgical samples, ceramics, soils, aggregates, chemicals and similar particulate. Typically, samples can be ground to 95% minus 75 micron in approximately three minutes, depending upon their mass and physical characteristics.

Unique safety features 
The Essa LM2 has advanced design features for a user-friendly experience with improved safety. 

• An external control box has motor overload, timer and pneumatic failure protection, preventing the bowl or lid from flying out in an uncontrolled manner. 
• A lid locking safety switch makes the chamber inaccessible during operation. It incorporates a time delay to prevent the operator from accessing the mill platform until the machine has completely stopped. 
• The mill will not start until the lid is completely closed. 
• The machine can be stopped quickly with the easily accessible emergency stop button. 
• The hard-wearing, stainless steel mill platform features improved accessibility and ergonomics. 
• The optional MillMate pneumatic lifting device allows for reduced manual handling.
