VSI Crusher

Seiko produced

Unmatched performance

With thousands of units operating in aggregate and mineral processing installations around the world Barmac. PCL-Series VSIs, with their rock-on-rock crushing action, have an established track record of cost savings, durability and unmatched performance in the variety of tasks to which they have been applied. These include the production of quality aggregates, sand, material for heap leaching, pre-grinding and fi nished industrial minerals products.

Lowest total cost

The Barmac PCL-Series VSI provides higher capacity for a given motor size, easier servicing and reduced operating costs. VSI  have been achieved by an improved machine design, including a new hopper configuration, radical crushing chamber variations and the development of new rotor technology. Service time is drastically reduced with complete access to all rotor parts, simplifying wear part replacement procedures.

1．

Visual indication of cascade control gate position which allows for precise control of material flow.

2．

Large feed hopper gives room for staff to work in when servicing the crusher.

3．

Simple feed tube replacement with automatic realignment after crusher servicing and rotor replacement.

4．

Adjustable cascade ports allow operator to control cascade flow.

5．

Adjustable spreader plate angle and height controls the flow of feed.

6．

Roof lifter gives rapid access to the inside of the crusher meaning minimum time is required to carry out servicing and maintenance tasks.

7．

Quick access through inspection and service door allows insitu parts replacement.

8．

Low profile allows installation into tight fitting existing plant situations.

Product Structure

The complete range of Barmac PCL-Series VSI crushers incorporate rock-on-rock crushing technology that has revolutionised the aggregates and minerals industries worldwide. The rock-on-rock Barmac B-Series VSI off ers the modern operator product grading control by optimising numerous variables:
• Variation of rotor speed.
• Choice of crushing chamber cavity rings.
• Adjustment of cascade feed ratio.
• Selection of different diameter rotors.

Benefits

Product Performance design

1.Improved efficiency and throughput

Cascading material combines with material from the rotor to form a denser particle population, which optimises reduction by increasing the chance of a good rock-on-rock collision. This most efficient use of the rock on-rock crushing action leads to improved crusher efficiency and increased throughput, giving the operator more value for money by providing more inter-particle action where it is needed most in the crushing chamber.

2.The unmatched producer of superior concrete and asphalt aggregate

Less cement can be used and stronger concrete created by using Barmac PCL-Series VSI product. The Barmac PCL-Series VSI combines high velocity impact crushing with high pressure attrition grinding to produce high volumes of cubically shaped product. Continuous control of the product shape and gradation provides a product which meets the size distribution required.

3.A proven producer of quality manufactured sand

Superior particle shape and consistent gradation are a direct result of the rock-on rock principle of the VSI crusher. Impact, grinding and abrading within the crusher simulates the action of nature, eroding the particles to a cubical shape.

4.The only viable crusher for extremely abrasive fine material

The rock-on-rock crushing principle of the Barmac PCL-Series VSI minimises metallic wear resulting in low maintenance and wear costs. The low wear of internal components ensures extremely low contamination of fi ne products by wearing metal parts.

Structural Design

5．The User-Friendly VSI crusher

The roof lifter has been developed to provide quick and easy access to the internal workings of the Barmac B-Series VSI. This allows for rapid rotor and wear part changes and minimises down time while maximising availability. The simple and reliable design of the roof lifter means only one person is required for operation and can eliminate the requirement for an external crane.

7．The cascade feed system

The cascade feed system provides:
• Higher crusher throughputs for the same power consumption.
• Maximum use of available power without fear of motor overload.
• Gradation control to optimise product fractions.
• ‘Free’ crushing at no extra expense to the operator.
• Shape control.
