Bowl and Disc Pulveriser Bowls

A unique range of bowls from 10 to 5000cc nominal capacity

The patented bowls consist of a single, solid “flying saucer” shaped puck operating in a bowl with a concave curved bottom surface. The mass of this single puck in combination with the spatula like grinding interaction between its lower curved surface and that of the bowl provides superior pulverizing with grinding performance. The puck also has an off-centre, truncated hole through it to assist in the mixing of the sample to assure homogeniety. These bowls are of through hardened steel construction for optimum life. They are available in 800, 1000, 2000 and 5,000cc nominal capacity.

Autobatch Mill

An automated vibratory ring mill for preparing up to 1.8kg of ore or mineral for analysis.

The Autobatch™ is an “automated” adaptation of the very successful Labtech Essa model LM2 batch ring mill incorporating a permanently attached, self-discharging bowl which is air blast and vacuum cleaned between batches (with the residue going to the customers dust collection system). The unique Labtech Essa ”flying saucer” puck style of bowl integrated into this machine assures a homogeneous sample is prepared. Bowl discharge and cleaning is controlled by an onboard PLC which also controls the milling cycle. Operator functions are reduced to tipping the feed sample into a feed hopper, pressing a “start” button and removing a container that receives the milled sample. These 3 only manual operations can be replicated by a robot thereby making the Autobatch™ ideally suited for integration in to a robotic cell.

Ring & Roller Pulveriser Bowls

Essa traditional ring and roller style bowls are available in 50, 100, 125, 300 & 400cc nominal capacity. These too are of through hardened steel construction as standard, with optional materials available on request.

LM2 Pulverising Mill

Vibratory mill for rapidly preparing up to 1.8kg of ore for mineral 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 LM2 mill 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 3 minutes depending upon their mass and physical characteristics.

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.

LM1.5 Pulverising Mill

Vibratory motor driven mills for rapidly preparing up to 1.8kg of ore or mineral for analysis

The LM1.5 is a reliable and robust adaptation of the traditional vibratory ring mill that incorporates an integral 3 phase vibratory duty electric motor drive. This mill however differs from traditional mills because of its 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 LM1.5 mill is used for pulverising ores, minerals, metallurgical samples, ceramics, soils, aggregates, chemicals and similar particulates. Most samples can be ground to 95% minus 75 micron in 1 to 3 minutes depending upon their physical characteristics. These machines are well suited to laboratories mainly using traditional ring and roller bowls but who also want to use the range of higher capacity bowls on an intermittent basis to prepare larger batches of homogeneous sample.

The LM1.5 has a more powerful drive motor than the LM1 and is recommended when the largest bowls are used frequently and/or when the mill is to be connected to a 60 cycle power supply.

LM1 Pulverising Mill

Vibratory motor driven mills for rapidly preparing up to 1.8kg of ore or mineral for analysis

The LM1 is a reliable and robust adaptation of the traditional vibratory ring mill that incorporate an integral 3 phase vibratory duty electric motor drive. This mill however differs from traditional mills because of its 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 LM1 mill is used for pulverising ores, minerals, metallurgical samples, ceramics, soils, aggregates, chemicals and similar particulates. Most samples can be ground to 95% minus 75 micron in 1 to 3 minutes depending upon their physical characteristics. These machines are well suited to laboratories mainly using traditional ring and roller bowls but who also want to use the range of higher capacity bowls on an intermittent basis to prepare larger batches of homogeneous sample.

LM5 Pulverising Mill

Grinding time will be approximately 5 to 8 minutes.

Continuous Ring Mill

A special adaptation of the Ring Mill capable of processing larger batches of mineral sample on a continuous flow through basis.

The Essa continuous ring mill is selected for those applications where ring milling would be the preferred method of reducing a coarse sample to analytical fineness but the quantity to be milled is greater than the capacity of a standard ring mill. Ring milling is a preferred methodology for rapidly reducing coarse mineral, ore and similar particulate to the degree of fineness required for laboratory analytical procedures. The resulting sample is homogeneous and repeatability is excellent. Each batch is processed on a one-at-a time basis in a sealed bowl to minimise the possibility of contamination from the outside or the loss of sample as dust. The largest batch that can be prepared in a ring mill however is only approximately 5kg. When a need is seen to prepare larger samples, they can be processed in a standard ring mill in smaller batches on this one-at-a-time basis and then be recombined or the Labtech Essa Autobatch™ ring mill can be used to perform this same function on an automatic basis.

Micron Mill

Revolutionary New Milling Process

Essa Australia has developed a very large capacity (sample masses up to 10kg) Micron Mill that utilises a patented ® “ring and spigot” milling process. This innovative milling configuration provides rapid preparation of large samples with sample division at smaller particle sizes.

It has been principally designed as a large capacity coarse mill to achieve a 95% less than 250 micron product. This results in a significant improvement in quality of the final sample which will be more representative. The whole sample can be processed in one pass.

Use of the Micron Mill will greatly enhance the division process and allow smaller samples to be reliably split. It allows for larger samples to be taken at the drill rig to be prepared in the laboratory more efficiently. It may also eliminate the need to use a fine jaw crusher for primary crushing.

The Micron Mill allows for automated loading, discharge and cleaning.
