Screw conveyors for bulk materials handling and processing

Since 1949, Jacmor Engineering, has specialised in the design and manufacture of screw conveyor systems and their application to processing and handling of bulk materials. Our skills and expertise are recognised in a wide range of industries with Jacmor designed and manufactured equipment operating throughout Australia and overseas markets.

Jacmor screw conveyor systems are working right now in aluminium refineries, chemical plants, power generating stations, coal wash facilities, bakeries, flour mills, sewerage works, timber and pulp mills, refractories, food processors and many other industries. They are the most efficient cost effective method of bulk materials handling in many of today's processing and manufacturing industries.

Their long life, simplicity of maintenance, high efficiency even under partial load and reliability when handling heavy and demanding materials give them outstanding advantages compared with alternative systems.

Screw conveyors

Screw conveyors form an integral part of many production processes. Mixing, blending, heating, cooling, liquid extraction, dewatering, drying or similar operations can be performed whilst bulk solids or liquids are being conveyed from one point to another.

Screw conveying is not limited to transporting materials on a horizontal plane. Standard designs with auxiliary equipment are available for operating on inclines or for the vertical elevation of materials.

The use of solid state digital control systems, PLCs (program logic controllers) and loss of weight feeders add a high degree of sophistication and control.

Highly developed seals confine the products conveyed within the trough along with dust, fumes or gases. Materials can similarly be protected from contamination and the elements.

Comparatively compact, screw conveyors do not require a return run, are virtually vibration free and relatively quiet in operation. Multiple inlet and discharge points are easily incorporated.

Screw conveyors are capable of continuous operation, usually require minimal maintenance and are considered to be relatively inexpensive equipment resulting in cost effective processing operations.

Screw Feeders

When screw conveyors are used to discharge material from the base of bins or hoppers, they are designed as screw feeders and can accurately meter the materials being discharged.

Live Bottom Bins

When multiple screw feeders are used to empty the contents of a bin, they are called "live bottom bins" and are ideally suited for discharging materials that have a tendency to pack or bridge.

Mixing and Blending

Jacmor manufacture a wide range of mixers and blenders suitable for use in many industries including the food industry. A complex ribbon design promotes thorough homogenous mixing of a multitude of products in large batches.
