New and better ways to handle chemicals safely

ChemicalFinding new and better ways to handle chemicals safely and efficiently keeps Hapman generating fresh ideas. Innovative conveyor designs move singular and blended ingredients without degradation or segregation. Completely sealed systems safely contain dust, odors and toxic fumes; prevent product spillage and contamination problems, too. Glove box access gives workers additional protection with hazardous materials.

Yet Hapman also knows how important it is to control costs and improve process efficiencies. Several of our conveyor designs are portable so one model can do the work of two or three. Other designs offer floor-to-ceiling installation flexibility or configurations that can easily be changed. Hapman dust collectors eliminate the expense of auxiliary fans and filters. All Hapman products minimize cleaning and maintenance. And if you need to clean or sanitize your material handling equipment, we offer the finishes, sealed motors and controls suitable for washdown and explosion-proof applications.

Hapman offers solutions for some of chemical processing’s biggest challenges:

And those solutions have helped to create a full line of material handling and conveyor equipment that you can use individually or as a system:

So if you are ready for safety and efficiency results, Contact us. We’re ready to start.

Application Review: Vacuum Conveying System Eliminates Cross-Contamination for Pharmaceutical Company

Vacuum ConveyorCHALLENGE
A major pharmaceutical company came to Hapman for assistance in providing them with a vacuum conveyor system to meet their specific requirements. It was to take their finished product from a dryer and discharge it into a mobile bulk material handling system, which was scale mounted for precision metering and batching. The problem was that it needed to incorporate an efficient cleaning system which totally eliminated any possibility of cross-contamination with product change overs.

Application Review: Hapman Engineers Mobile Industrial Processing System that Meets the Mixing & Blending Demands of Changing Manufacturing Environments

Mobile Bulk Material Handling SystemCHALLENGE
Mobile production, or modular pre-processing, is becoming increasingly vital to all major process driven industries and range from oil and gas, chemical, and energy, to food processing and pharmaceutical. One way to overcome the challenge of processing new raw materials in uncertain operating environments is to mix or pre-process at the source rather than trucking feedstock directly from the sourced location. Mixing material at the source can reduce transportation and processing costs, and improve chemical volume and quality through mixing or pre-processing.

Application Review: Bulk Bag Unloading Stations with Integral Pneumatic Conveying System Accurately Delivers Metered Materials

Deliver measured amounts of four powdered ingredients, received in bulk bags to slurry tanks. Some materials are hygroscopic, flow poorly in humid environments and may contain small agglomerations. Whereas some materials do not mix readily into solution, the delivery must be metered so as not to exceed the mixers ability to force it into suspension. System must be automatic and fit into an existing manufacturing space with a very limited footprint. Housekeeping is a concern- provision to minimize the escape of airborne product is essential. Control system must be open architecture and comprised of commonly available, highly dependable components to minimize downtime.

Application Review: Tubular Drag Conveying System - Tire Manufacturer with Dust-Free Multiple Inlet System Handling Carbon Black

Tubular Drag ConveyorCHALLENGE
A major tire manufacturer needed to fit a material handling conveyor into a tight space, move the material (carbon black) from inlets and discharge it at two locations. In addition, the intermediate discharge had to be free of residual build-up, and the entire system dust free.

Application Review: Portable Bulk Bag Unloading - Chemical Company Charging Hoppers with Limestone Combining with Helix® Flexible Screw Conveyor

Bulk Bag UnloaderCHALLENGE
A chemical company had to periodically charge their holding hoppers with ground limestone. Due to the number of hoppers and their infrequent need for charging they did not feel that it was going to be cost effective to purchase a bulk bag unloader for each one.

Application Review: Tubular Drag Conveying System - Mining Operation Handles and Conveys Ammonium Nitrate Reducing Degradation

Tubular Drag ConveyorCHALLENGE
A mining operation located in the mountains of Chile required an equipment method to handle and convey ammonium nitrate (NH4NO3) without degradation, 50 feet vertically, into a silo. Their current method of air conveying was damaging the prill of the material, resulting in an oxidizing agent which was proving less than expected reaction performance.

Case Study: Tubular Drag Conveying Technology

The analysis of the optimal conveying method begins with understanding system and material variables such as; energy requirements, bulk density of material, purchasing/storage of material prior to use, conveying distance, space and location, and durability and maintenance. These are just a few of the many elements that must be considered in conveyor selection and design.

Case Study: Bulk Bag Unloader and Vacuum Conveyor System Automates Material Handling and Adds Cost Savings

Bulk Bag Unloader InstallationCHALLENGE
Werner G. Smith, Inc. was awarded a long-term contract from a new customer which required the blending of a granular powder with an aqueous chemical solution. Under the terms of the agreement, the customer would provide the raw materials and WGS would make the product in accordance with the specifications set forth in the agreement. The job began at a time when WGS had extra capacity in one of its large reactors allowing the reactor to be dedicated for this process. Dedicating the unused processing space was an excellent way for WGS to maintain on-time deliveries while still accepting new work from other customers. The building where the product was intially made had no loading dock, which meant 55 lb bags of raw material had to be hauled and processed manually.

Tech Brief: Top Equipment Design Considerations for Handling Bulk Chemical Powders

Portable Dust Collector and Bag CompactorSUMMARY
Successful conveying and handling of chemical powders requires much more input than understanding a material’s properties, the desired convey rate and distance. Today’s manufacturers are faced with tighter margins, leaner operations, shorter lead times and greater environmental concerns. Maintaining plant and worker safety is paramount.

White Paper: How to Get the Most Out of Your Flexible Screw Conveyor

Increasing Conveyor Performance and Efficiency
Due to their relatively low cost and simple construction, flexible screw conveyors are one of the most common types of conveyors used by manufacturers. The reason for this is that the screw is the only part of the conveyor that moves. The only other major components are the tubular housing, and the electric motor that drives the screw (also called the auger).
