- Industrial rotary drums for suitable pebbles and decorative stone batches.
- Compare the listed RB models against stone size, batch loading, and finish targets.
- Review water handling, solids removal, installation, and representative stone trials.
Pebble Stone Polishing Machines
Inovatec supplies rotary drum equipment for assessing edge rounding and surface finishing of suitable pebbles and decorative stones. Select the proposed model around the actual stone batch, loading requirement, and target texture. Edge rounding and a fine polished gloss are different objectives, and not every mineral or mixed batch will produce the same result.
Compare the listed rotary drum models and their individual specifications. Motor power, rotational speed, and capacity are model-dependent. Confirm the proposed drum, loading basis, drive, discharge arrangement, and any quoted feeding option rather than treating one model’s data as a specification for the whole range.
Review a larger drum for the required production batch and installation. The table lists the RB40K with a 2000 x 7000 mm barrel and a 30-40 tonne capacity range. Confirm the engineering drawing, rated loading basis, utilities, handling, and foundation requirements in the quotation.
Stone and Decorative Material Applications
Identify the minerals present, stone size distribution, existing cracks, and required texture. River origin alone does not establish processing behavior. Assess representative material before selecting the finishing proposal.
Define whether the landscaping requirement is edge rounding, a smoother surface, or an approved decorative appearance. Provide the actual stone batch and loading requirement. A larger machine does not automatically shorten the process or improve the result.
Confirm the stone or manufactured material and whether the color is natural, dyed, coated, or otherwise applied. Agree on the intended texture and color retention during assessment. Do not assume that every colored batch can reach the same gloss.
Glass is a different material from natural stone and needs its own assessment. Specify whether a frosted appearance, rounded edges, or a different finish is required. Check representative pieces for the agreed result and unacceptable breakage before quoting a production process.
Review the composition and variation within the batch. Different minerals, structures, and pre-existing defects can produce different finishing results. Agree on acceptable sorting and finished appearance using representative samples.
Provide the stone type, size range, intended decorative use, and approved surface reference. Review handling and recovery of the finished batch with the proposed equipment. Small size alone does not guarantee a rapid cycle or high gloss.
Stone Finishing Media and Consumables
Some applications may be assessed for stone-on-stone finishing; others may require additional abrasives, media, or polishing compounds. Select consumables for the actual stone and the target result. Porcelain media are not a universal route to a glossy finish, and the complete proposal should be supported by a representative trial.
- Identify the stone or decorative material and supply representative samples.
- Provide the size range, required batch mass, and target surface appearance.
- Review the model-specific capacity basis, drive, loading, and discharge provisions.
- Confirm installation, water and solids handling, documentation, and acceptance.
- Factory
- Before & After
Provide the actual mineral or material composition, size range, and required finish. River stones, decorative pebbles, and glass do not all use the same process. Suitability and acceptable breakage should be evaluated with representative material.
Confirm timing through a representative trial for the stone and target finish. There is no universal cycle time for all stone types and finish targets. Excessive processing can change size or texture and may cause unacceptable wear or breakage.
Provide the full size range and the largest pieces expected in production. Confirm the allowable feed size, drum loading, handling provisions, and discharge requirements for the selected model in the quotation.
Plan the installation, lifting, foundation, utilities, guarding, and commissioning around the quoted machine and its documentation. Operators need training for loading, operation, cleaning, and maintenance. Do not assume that an industrial drum is ready for production without these checks.
Confirm the proposed internal lifting arrangement, flushing, drainage, and solids removal with Inovatec. Rubber lining and other internal features must be specified in the quotation when required. Review the material and expected debris when planning water treatment and waste handling.

How is a pebble polishing drum selected?
Start with representative stone, size distribution, required batch mass, and the target surface. Compare the listed RB models, then confirm the drum, drive, loading basis, and handling arrangement. A nominal tonnage is not a complete selection criterion; the quoted duty and installation must be reviewed together.
What is the difference between rounding and polishing?
Edge rounding changes the outline and surface condition of a stone. A fine polished gloss is a different target and may require a different proposal. Agree on a reference sample that represents the actual desired result. Do not describe every tumbled or rounded stone as highly polished.
How do stone properties affect the result?
Rocks can contain minerals with different hardness and structures, and a batch may include porous or fractured pieces. These differences affect the response to abrasion and the appearance obtained. Assess the actual material and acceptable variation rather than assigning a universal process to a river or gardening label.
How are processing time and output established?
Establish the proposed cycle through a representative trial and review the full loading, discharge, cleaning, and handling sequence. Include acceptable breakage, wear, and finished appearance in the assessment. Processing longer is not always beneficial, and a larger rated drum does not by itself establish greater finished output.
When are additional media or compounds considered?
The trial should determine whether the supplied material can meet the target through stone-on-stone finishing or requires additional consumables. Identify the proposed abrasive, media, or compound and its intended duty. Cleaning and carryover requirements should also form part of the accepted process.
How should rotary and vibratory proposals be compared?
The equipment range shown here is based on rotary drums. If a vibratory alternative is proposed, compare its working chamber, handling, capacity basis, and demonstrated sample result separately. Do not transfer a drum’s rating or operating assumptions to a different equipment type.
What installation and environmental provisions need review?
Review foundations, lifting, loading access, guarding, noise, water supply, drainage, and solids handling for the quoted arrangement. Stone processing can create dust from silica-containing materials; arrange appropriate exposure controls and housekeeping based on the material assessment and applicable workplace requirements. Wet processing does not remove the need for an assessment.
What information is needed for a quotation and trial?
Send the material description, representative samples, stone size range, batch mass, required appearance, utilities, and installation information. Confirm the trial acceptance record, model-specific specifications, included options, and water-handling scope. The listed technical table provides model information; confirm the delivered configuration in the written offer.
