Engineering process routes

Four representative plant routes, organized by material, process sequence and the conditions that still need engineering confirmation.

Application guide / MC-S04

Read the process before choosing the machine.

These are generalized application guides, not records of named installations. Capacity and product ranges are preliminary design envelopes until feed behavior and site constraints are checked.

Granite crushing plant

A hard-rock route for granite, basalt and similar abrasive feed, producing graded aggregate for road base, concrete and construction fill. The proposed stage count depends on top size and required product shape.

Indicative output: 100–500 t/h
Best-fit application: Road construction, concrete aggregate and railway ballast

Typical process sequence

1
A PE jaw crusher performs primary reduction and is selected around the maximum lump, full feed grading, and the feed limit of the next stage.
2
A spring cone crusher handles secondary or tertiary reduction where wear resistance and controlled gradation matter.
3
A vibrating screen separates typical 0–5, 5–20 and 20–40 mm product fractions; screen area and recirculating-load margin must also cover the documented wet-feed case.
4
Conveyors connect the stages; transfer-point design controls spillage and dust exposure.
5
A spray or extraction system can be configured to suit the site dust-control requirement. Where seasonal contamination matters, document separate dry- and wet-feed setpoint windows and acceptance checks.

River-pebble sand making

A shaping and washing route that converts river pebble or gravel into manufactured sand. Feed grading, clay content and the required concrete standard determine the recirculation and washing scope.

Indicative output: 50–300 t/h
Best-fit application: Manufactured sand for concrete, mortar and asphalt filler

Typical process sequence

1
A jaw crusher reduces oversize pebble to a feed range the shaping stage can accept.
2
A VSI sand-making stage would normally shape particles toward a 0–5 mm manufactured-sand fraction; that machine family is not yet documented in this catalogue.
3
An XS wheel sand washer removes clay and excess fine powder where washing is required; sample overflow solids instead of treating crusher throughput as saleable sand yield.
4
A dewatering screen reduces free moisture before stockpiling or transfer.
5
The modular arrangement leaves room for recirculation or later capacity expansion. The RFQ should include a water-and-fines mass balance, target 0–5 mm yield, and fine-loss acceptance method.

Limestone powder processing

A closed grinding and classification route for desulfurization powder, cement admixture and calcium-carbonate production. Product fineness and moisture must be confirmed before mill sizing.

Indicative output: 5–30 t/h
Best-fit application: FGD desulfurization, cement admixture and calcium-carbonate production

Typical process sequence

1
A jaw crusher reduces quarried limestone to the feed size required by the selected mill.
2
A suitable fine-grinding mill or ball mill performs the main duty; target fineness must be confirmed by product specification and material testing.
3
Air classification returns oversize material to the mill and controls final particle size.
4
A pulse-jet baghouse collects fine product and keeps the conveying circuit enclosed.
5
PLC control coordinates feed, circulating load and product collection for stable operation.

Mobile crushing station

A wheel- or track-mounted route for contractors, recycling work and remote quarry duties where relocation and a limited civil scope matter more than the lowest long-term cost per tonne.

Indicative output: 50–350 t/h
Best-fit application: Construction-waste recycling, temporary quarries and road camps

Typical process sequence

1
Jaw or impact crushing, screening and conveying are integrated on one or more mobile chassis.
2
A prepared site can reduce fixed-foundation work and shorten deployment compared with a permanent plant.
3
Diesel or diesel-electric drive supports sites where grid power is unavailable or unstable.
4
Power generation and auxiliary loads must be defined in the mobile-station supply scope.
5
Access control and operating procedures must keep personnel outside the active crushing zone.

RFQ scope / budget basis

Compare one delivery boundary before comparing cost.

A 300 t/h line has no defensible universal price without a quotation date, currency, destination, trade term, feed basis, product split, electrical standard, and delivery scope. Use one written boundary for every bidder.

Machine only

Define the named crusher or process unit, motor, base accessories, guards, and the exact exclusions.

Mechanical package

Add feeders, screens, conveyors, chutes, steelwork, dust or water systems, and the first critical-spares package.

Complete project boundary

State civil works, electrical distribution, automation, freight, installation, commissioning, training, and acceptance testing.

Inputs required for a comparable quotation

Quotation date, currency, Incoterm, destination, and tax boundary
Maximum feed, grading, hardness, moisture, and contaminants
Required products, hourly duty, operating hours, and availability target
Site voltage, elevation, water, civil, installation, and commissioning boundary

Project brief

Start with the operating duty, then narrow the equipment path.

Share four operating inputs so we can rule out unsuitable models early and explain the assumptions behind the shortlist.
