Automatic Mechanical Soil Compactor
Product Code : LSK-SM-10660
Automatic Mechanical Soil Compactor (SKU LSK-SM-10660) is an automatic compaction machine that drops a rammer onto soil in a mould, compacting samples quickly and giving a uniform degree of compaction from layer to layer. Civil engineering students, diploma trainees and soil testing technicians use it to prepare Proctor, CBR and consolidation specimens. Engineering colleges, polytechnics, TVET institutes, tender contractors and distributors can order this automatic Proctor compactor from Science Lab Supplies, which dispatches it from Ambala, India.
Specifications
Each specification of the automatic compactor has its own row in the table below. In short, a standard 51 mm rammer works at either 2.5 kg over a 305 mm drop or 4.5 kg over a 457 mm drop, fits 102 mm and 152 mm ID moulds, and counts blows until it stops at a preset number.

Applications and Experiments for the Automatic Soil Compactor
The compactor is used wherever soil must be compacted with a controlled, repeatable effort: the Proctor moisture–density test, CBR specimen preparation and consolidation samples. It suits soil mechanics practicals in B.Tech and diploma civil engineering, TVET road construction modules and research labs that need uniform specimens.
- B.Tech / B.E. civil engineering: light and heavy Proctor compaction to find optimum moisture content and maximum dry density, with moisture samples dried in the Laboratory Bench Oven.
- Diploma (polytechnic) civil engineering: compaction practicals where many samples must be prepared in one lab session.
- TVET road construction and materials testing modules: compacting specimens in 152 mm moulds, then penetrating them on the CBR Test Machine Hand Operated.
Standard Scope of Supply
The compactor is supplied as a single machine with its rammer arrangement and automatic blow counter, as described above. Each quotation names the moulds and rammer weights included in the offer, and moulds of either 102 mm or 152 mm diameter can be added as separate lines.
Packing, MOQ and Lead Time
Ask for a quotation for one compactor or a full soil mechanics lab quantity; each quotation sets out the packing, delivery time and price for that order. Moulds, a bench oven or CBR equipment can go on the same quotation, so a single TVET lab equipment supplier covers the bench.
As a registered exporter holding an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Zambia, Rwanda, South Africa, Qatar, Sri Lanka and Vietnam. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). Send rammer and mould preferences through the contact page, place the compactor in the enquiry cart beside other soil items, or turn to the lab tender page for a tendered purchase.
Frequently Asked Questions
What does an automatic compactor do that a hand rammer does not?
It lifts and drops the rammer by itself, counts each blow and stops at the preset number, so every layer gets the same compactive effort and results vary less between students.
Which compaction tests can it be set up for?
The listed 2.5 kg/305 mm and 4.5 kg/457 mm weight and drop combinations, used with 102 mm or 152 mm ID moulds, cover light and heavy compaction for Proctor and CBR specimens.
Who supplies the Automatic Mechanical Soil Compactor?
The compactor is supplied by Science Lab Supplies from Ambala, India. Colleges, polytechnics, training institutes and contractors receive a quotation that spells out the rammer weights, mould sizes and blow counter set-up being offered.
Can the compactor be quoted against a tender specification?
Yes. Send the tender specification, quantity and delivery location through the contact page for an item-wise quotation covering the rammer, both mould sizes and the blow counter.
