Why Upgrade Existing Bulk Material Handling Equipment?

Posted by David Phillips on Tue, Apr 14, 2015 @ 09:04 AM

An all-too-painful truth is that bulk material handling equipment breaks down over time, and whenever it occurs, it's almost always costly.  The most common problems that lead to breakdowns are actually quite preventable.  They include improper maintenance, overrunning a machine's capability, not replacing worn parts, poor electrical connections, and even operation by untrained personnel or not consulting the operator manual.  Almost all mean that someone has ignored the warning signs of an impending stoppage.  These problems account for most of the breakdowns seen in the field, and all are avoidable by taking some simple precautions.

Torrefaction Equipment Converts Wood Biomass into Biocoal

Posted by David Phillips on Wed, Apr 08, 2015 @ 09:40 AM

Biomass co-firing is the burning of fossil fuels in coal-fired power plants in conjunction with forestry and agriculture residues, animal manure, wood wastes, such as sawdust or bark from the timber industry, waste wood and dedicated energy crops. Co-firing increases the amount of renewable biomass in the global energy mix and also reduces greenhouse gas emissions. The technologies include biomass that is jointly milled with coal and fed into the same boiler, biomass that is converted into a fuel gas and then burned with coal in the same boiler, and biomass in a separate boiler that supplies steam to a coal cycle.

Heyl & Patterson Develops Equipment for Asteroid Mining

Posted by David Phillips on Wed, Apr 01, 2015 @ 09:00 AM

There is a wealth of raw minerals above our heads, in the form of near-Earth asteroids and our own Moon. Iron ore, nickel, manganese, titanium and other minerals can be mined and processed on-site and then transported back to Earth, or used in space as construction materials. A number of high-tech tycoons, including Google founder Larry Page and Hollywood director James Cameron, plan to be the first prospectors in this new frontier by establishing a new paradigm for resource implementation.

Unloading Wood Chips for the Production of Paper Pulp

Posted by David Phillips on Wed, Mar 25, 2015 @ 09:48 AM

Even in today's "paperless" world, there continues to be a huge demand for paper.  Paper is made from wood pulp, which is also used to manufacture a wide variety of products from diapers to particle board to textiles. The pulp itself is the cellulose, lignin and hemicellulose components of wood fibers, which are separated from one another through steaming, cooking or mechanical grinding processes.  Most pulp is made from a mixture of sawmill residue, logs, wood chips and recycled paper, and it is interesting to note that practically all of the fibers that end up as pulp originally existed as trees.

Fertilizer Drying Leads to Higher Yields

Posted by David Phillips on Wed, Mar 18, 2015 @ 09:30 AM

Farmers are responsible for nearly every morsel of food we see on our tables each day.  Whether it's crops of grains, fruits and vegetables, or feed for the animals that provide us with meat and dairy products, ensuring that growers are able to get the best possible fertilizer is not just in their best interest, but everyone's.  Fertilizer dryers come into play in order to get higher yields, and to understand why, it is necessary to first take a brief look into what fertilizer does and its important role in our lives.

Railcar Moving Devices Offer More Efficiency Than Locomotives

Posted by David Phillips on Wed, Mar 11, 2015 @ 09:10 AM

Rack-Drive-PositionerLocomotives are a common means of moving railcars and strings of cars, but that action does not make them rail car movers.  Ports, power plants and industrial facilities share the logistics of locomotive use to break trains into strings, transfer strings to the loading or unloading facility, position individual cars for loading or unloading, re-assemble trains and perform other rail duties at a particular facility.  However, more manpower is needed, and safety is always a major concern.  Line of sight is never optimal, so any train movement could result in injury or worse.

Pugmill Mixers and Factors that Impact Their Performance

Posted by David Phillips on Wed, Mar 04, 2015 @ 09:20 AM

The best option when searching for a pug mill mixer may be to consider six factors: agitation, drive assembly, inlet, discharge, cost and maintenance. When analyzing these options, take into account the ideal design features and decide which variables upon which it may be necessary to compromise. Finding a pug mill mixer that exactly fits an entire list of criteria may be impossible, because even if a custom solution is an option, then the cost could end up breaking the budget.

Turning Powders, Dusts and Sludges Into Easy-To-Handle Granules

Posted by David Phillips on Wed, Feb 25, 2015 @ 09:00 AM

Agglomeration and granulation are two common terms used in process industries, and they are actually synonyms.  Granulation is the process of forming a powder, dust or sludge substance into multiparticle entities, and the resulting granules can vary in size from either 0.2 to 4 mm depending on their specific use.  Agglomeration is also known as particle size enlargement, and is a general wide-spectrum term for granulation.  These technologies are excellent tools to modify mass product properties for further and easier processing.

Silica Gel and Its Use as an Effective Catalyst

Posted by David Phillips on Wed, Feb 11, 2015 @ 09:30 AM

Silica gel is a hard, porous form of silicon dioxide that is commonly processed into beads or granules and used as a dessicant, and is inside the permeable paper packets marked "DO NOT EAT" that are found inside many products.  The substance is made from sodium silicate, and its strong affinity for water molecules causes it to adsorb wetness and prevent mold from forming, which spoils many products.  Chemically, silica gel removes water vapor through adsorption of its numerous surface pores rather than by absorption into the gel itself.  Most people may be aware of silica gel to some degree, but not everyone knows how it is made.
