Pneumatic conveying and packaging systems for minerals and dry bulk solids

Magnum Systems has engineered, designed, and manufactured quality pneumatic conveying, weighing, filling and packaging automation systems to handle dry bulk solids such as concrete, limestone, grout, bentonite, clay, salt/ice melt, asphalt, charcoal, coal, metal compounds, pellet fuels and other aggregates.

We have served various markets since the 1960s and our extensive product offerings in pneumatic conveying and packaging equipment have provided our vast customer base with reliable, proven systems they can count on to keep their process moving. We have conveyed, stored, packaged, batched, weighed and filled products from ash to zinc.

Below are examples of conveying and packaging systems we have provided for various applications when handling industrial minerals and bulk solids…

  • Dilute and Dense phase pneumatic conveying systems
  • Bulk storage, loading, and unloading of silos, bins and hoppers
  • PD Truck, railcar unloading and transfer systems
  • Pressure and Vacuum transfer systems of granular and powder materials
  • Bulk bag filling and unloading systems
  • Open-mouth and valve bag filling, weighing and packaging systems
  • Robotic bag placing and palletizing
  • Rotary Valves for Asphalt metering from Bins, Hoppers and Dust Collectors
  • Gross weigh screw feeding and bagging equipment for cold patch asphalt
  • Wood Flour unloading and transfer systems from rail and pd trucks to silos
  • Color Concentrate Unload and Transfer Systems
  • Impeller valve bag packers for bagging cement like Quikcrete®

Asphalt – Packaging Application

IAPO Full Line Bagging System with PalletizerProject Scope – Provide a complete packaging system for filling and palletizing 50lb (22kg) bags, including an external material loading hopper, Incline auger packaging machine, bag sealer, conveying and Robotic Palletizer complete with Stretch Wrapping station.

Material Handled – Cold Patch Asphalt

Solution Overview – The system had to fit into an existing building. Still, the kicker was the material that needed to be introduced into the packaging system from outside the building, where it was delivered by a dump truck. So Magnum Systems determined the best layout for the packaging line internally while being able to overcome the external obstacles. The solution was to install the product loading hopper outside the building to be filled by a front-end loader in bulk. The hopper featured an inclined trough conveyor extending through the sidewall of the building and into the packaging line. The packaging system featured Magnum Systems TRP3000 Robotic Palletizer with two palletizing stations; once palletized, the operators transfer the stacked pallet to a Shrink-Wrapping station for final preparation and shipment.

Grout Processing Plant – Pneumatic Conveying Application

Project scope – Dense phase conveying systems for sand and cement; Dilute phase conveying systems for silica flour and calcium carbonate.  This includes dense phase vessels, air management system retrofit, diverters, bin vents and controls.

Material Handled – sand, cement (2 colors), silica flour, calcium carbonate

Solution overview – The customer manufactures grouts and mortars.  Smoot company installed two new dense phase systems and retrofitted an existing one to eliminate boosters and increase the rate.  Also, diverters were installed to allow the material to go to a new mixer in addition to the existing mixers. Weighing systems were placed on either the pressure vessels for the dense phase systems or receiving bins for the dilute phase systems to promote batch accuracy and speed of mixing cycles.

Oil Field Additive – Pneumatic and Packaging Application

Project Scope – (2) Dense phase ASME code vessels, control system, bin vents, large hopper, dust collection, rotary valves, vacuum dilute reclaim system. (3) Impeller Packers, conveyors, robot placer, check-weigh, inkjet printing,  robot palletizer, pallet dispensing and conveying, stretch hood machine, gravity accumulation.

Material Handled – Barite

Solution Overview – The customer built a new facility to import Barite and grind it to a specified particle size to sell to their customers. Dense phase pneumatically transfers Barite from (2) milling/grinding locations to (4) silos across the plant. Barite was then transferred to multiple 50 lb & 100 lb bagging stations. Robots placed empty bags onto impeller packers to be filled. Once filled, the bags were moved on roller conveyors to be palletized by a robot. Once pallets were full, they were transferred to a stretch hood machine for transport to the oil field. Dust collection and reclaim systems were installed to reuse material.

Cement Plant – Pneumatic Application

Project Scope – Vacuum blower, filter receiver, rotary valves, knife gate valves, hoppers, multiple vacuum pickup points and an inlet filter.

Material Handled – Cement

Solution Overview – The customer had problems with mechanical conveying breaking down—the time and cost to repair cost the customer’s business. Magnum Systems proposed a pneumatic system to take bulk and minor additives to storage or a mixer. The vacuum system conveyed the additives to a filter receiver above a mixer. This provided a more reliable means to transfer the material by reducing equipment failures.

Mineral Additive System  – Pneumatic Conveying Application

Project Scope – The customer wanted to get rid of troublesome screw conveyors while moving their mix tanks further away. Magnum Systems recommended going to a vacuum conveying system to keep the area cleaner and get the specified rate to the tanks now 15 feet away.  Bulk pneumatic transfer, control system, filter receiver on load cells, rotary valves and vacuum blower were provided.

Material Handled – Talcum Powder

Solution Overview – Pneumatically transfers Talcum Powder from a silo across the plant to a filter receiver located above two mix tanks. Talcum was vacuumed from a bulk silo across the plant to the filter receiver. Once the filter receiver reached a high level, pneumatic conveying was stopped. Talcum powder was weighed and a specified amount was discharged through a rotary valve. The loss in weight was measured until the desired amount was reached.
