Solids Handling Lab Equipment

Solids do not behave like fluids, and that is the whole teaching problem. A powder that discharges cleanly in the morning arches in the hopper after a humid afternoon. Students arriving from flow and heat transfer meet their first genuinely variable system here, and the apparatus has to make that variability visible instead of hiding it inside a sealed box.

This category covers particle technology as it is actually taught: size reduction and grinding, screening and sieving, particle size analysis, mixing and blending of solids, mechanical and pneumatic conveying, storage and flow from hoppers, and separation of solids from gas and liquid streams. It serves chemical engineering departments first, but mechanical, mineral processing and mining adjacent programmes use the same bench. Scientico has manufactured and exported this equipment from its own works in Ambala, Haryana since 1993, to institutions in more than 60 countries, under an ISO 9001:2015 quality system.

Operations, apparatus and what students measure

Build the experiment list from this first and the purchase list second. The last column separates a specification that survives technical evaluation from one that returns three incomparable quotations.

OperationTypical apparatusWhat students measureWhat to check when specifying

Coarse size reductionJaw crusher, roll crusherReduction ratio, energy per unit mass, product size distribution, comparison of the crushing lawsFeed opening against the sample the department can source, face material, whether faces are replaceable, gap adjustment
Fine grindingBall mill, hammer mill, pulveriserGrinding time against fineness, critical speed, effect of ball chargeVariable speed with indication, jar or chamber lining, media supplied, grate screen options, guard interlock, noise

Liquid solid separationBatch settling column, thickener, plate and frame filter pressSettling curve and interface velocity, filtration rate, specific cake resistanceColumn graduation, cloth grade and replacement route, corrosion resistant wetted parts

Particle size work overlaps the material testing benches. Grain size distribution under the IS 2720 series and fineness work under the IS 4031 series use the same sieve sets and the same shaker, so a department running civil and chemical programmes can share one shaker if sieve stock is planned together. For anything outside those, write the applicable test method into the specification rather than a standard number that does not apply. The note on standards referenced in engineering lab testing covers how to phrase it.

Dust extraction is a facility requirement, not an accessory

This is where solids handling differs from every other bench in the department. Crushing, grinding, sieving and dry conveying all generate airborne fines. The apparatus has to be enclosed enough that the room stays clean and the class stays safe, and open enough that students can see the mechanism being taught. Those two demands pull against each other, and the resolution sits in the equipment features, not in a procedure taped to the wall.

Transparent guarding rather than sheet steel where the mechanism is the lesson. Polycarbonate over a crusher chamber, a cyclone body, a hopper face and a conveying line keeps the physics visible while the dust stays inside.
An extraction spigot on the equipment itself, at the discharge or enclosure, sized to connect to room extraction rather than left to a table top fan.
Gasketed covers, clamped sieve stacks and sealed collection pots, so fines end up somewhere retrievable instead of on the floor.
Interlocked guards on rotating mills and blenders, emergency stop within reach of the operating position, and no volt release so nothing restarts by itself after a supply interruption.
Anti vibration mounting, and a decision on bench or floor standing before furniture is ordered, because a shaker on the wrong bench becomes a noise complaint.

The facility side belongs on the room drawing at layout stage. A hood, a duct route and make up air are cheap while the layout is still on paper and expensive once benches are fixed. Sequence it with the build using the new lab setup timeline, and size the group against intake with the budget planning guide.

Wear parts and the recurring line nobody budgets

Grinding and conveying equipment consumes itself. That is not a defect, it is the operation. A crusher that never wears is a crusher nobody switched on. The failure is administrative: departments buy the apparatus from a capital head, then have no route to replace jaw plates from a revenue head three years later, and the unit sits idle for a term.

Wear itemWhere it sitsWhat drives the wearPractical approach

Jaw plates and roll facesCrushersFeed hardness and abrasiveness, running hoursConfirm faces are bolt on and replaceable, not welded in
Hammers, liners, grate screensHammer mills and pulverisersImpact and abrasion, feed contaminationOrder a spare set while the pattern is in production
Grinding media and jar liningBall millsMedia on media attrition, charge fractionWeigh the charge periodically and top up rather than replace wholesale
Test sievesSieve shakersMesh distortion, blinding, frame joint failureTreat sieves as consumables on their own cycle, keep one reference set unused
Belts, flights and bucketsConveyors and elevatorsEdge wear, tracking, abrasive carrybackCheck material at specification stage, confirm the section is a standard size
Cyclone cone and conveying bendsGas solid systemsErosion where the particle stream turnsAsk whether the cone section is separately replaceable
Filter cloth, gaskets, bearings and sealsFilters and every rotating unitBlinding, chemical attack, dust ingressRecord grades at handover and put them on scheduled inspection

Write the wear part list into the purchase document, not a follow up email. Set inspection intervals alongside it with the calibration and maintenance schedule guide, and fix the reorder route using the notes on spare parts and after sales support. Departments that do this keep the crusher running through an accreditation cycle. Departments that do not end up demonstrating grinding on a video.

Fitting this into the department list

Solids handling sits alongside fluid mechanics, heat transfer and mass transfer, and is usually specified last. The chemical engineering lab equipment list shows where it falls in the four year sequence, and the mechanical engineering list covers the material handling overlap. On paperwork, the AICTE lab requirements guide and the NBA documentation guide set out what an assessor expects against each experiment.

For distributors, resellers and tender bidders

This category is good business for a channel partner and it punishes a thin one. The equipment is heavy, it is usually bought as a group rather than singly, and it generates a wear part stream for years. What you need from a manufacturer here is specific.

Specification detail that survives technical evaluation. Solids handling tenders are where vague bids die. A committee comparing three offers looks for chamber dimensions, drive rating, face and liner material, guard construction, extraction provision and instrumentation supplied. We provide that detail on request so you bid against a written specification, not a brochure paragraph. If you are helping a department draft the specification, the specification writing guide and the tender document checklist are the two we send most often, and the GeM procurement guide covers the portal route.

Manufacturer authorisation for bids. Most institutional tenders here require a manufacturer authorisation form naming the bidder and the tender. We issue MAFs against a specific tender reference for partners bidding our equipment. If the term is new to your team, start with what MAF stands for, then the practical MAF process for lab equipment tenders.

Documentation you can hand to a buyer. ISO 9001:2015 certification, CE conformity documentation on applicable models, and factory calibration certificates with the instrumentation. We are not an ISO/IEC 17025 or NABL accredited calibration laboratory and we do not present ourselves as one, which matters because a buyer needing accredited certificates should arrange them locally rather than discover the gap at inspection. Current documents sit on the certifications page, manuals and drawings on downloads. Importers should also read the export documentation guide and the importer guide.

Spares over the product life, and installation responsibility. Agree before the bid who commissions the equipment, who trains the technician, and who holds fast moving wear items locally. On a crusher or a mill that answer decides whether the account renews. Partners evaluating us should work through the manufacturer due diligence checklist, and territory enquiries go through the dealership page.

Before the purchase list is signed

This group is most often specified late, after fluid mechanics and heat transfer have taken the bench space and most of the budget. That order causes two avoidable problems every time. The extraction a crusher, a mill and a shaker all need is a services item that belongs on the room drawing, and retrofitting it after the electrical layout is fixed costs more than it should. And the wear parts this equipment consumes become a recurring cost nobody owns unless it is written down at purchase.

Settle both at specification stage. Fix the extraction route and the socket positions before the benches are ordered, and put the wear part list, the inspection intervals and the spares route in the same document that carries the technical specification. Send the room dimensions, the intake, the experiments the syllabus requires and the available power supply, and you will get back a drawn layout, a specification written to survive technical evaluation, and a wear part schedule against each item.
