Pairing a compact mobile jaw crusher with a vibrating scalping screener transforms a single-product operation into a multi-product aggregate operation. Operations producing only crusher output (single gradation) compete only in markets that accept that gradation; operations producing 2-3 spec-sized products simultaneously compete across multiple market segments — premium concrete batch plant feedstock, hot-mix asphalt plant feedstock, road base material, structural fill, drainage stone, decorative aggregate, and others. The crusher + screener combination delivers the operational flexibility that separates limited-revenue operations from full-revenue operations.
This basic guide walks through how the K-JC 704 PLUS jaw crusher and Kompatto 5030 vibrating scalping screener combination produces multiple end products simultaneously — workflow integration, mesh selection for different finished products, market applications, customer training and on-site support, and the operational economics that make multi-product production work. The K-JC 704 PLUS is Komplet’s best-selling crusher; the Kompatto 5030 is Komplet’s best-selling screener — together they fit the operational sweet spot for typical contractor demolition and recycling operations.

Why This Combination Works Together
The K-JC 704 PLUS produces crushed material at gradations matched to the Kompatto 5030’s effective screening range. The crusher’s hydraulic jaw setting adjustment supports producing output appropriately sized for downstream screening; the screener’s 2-way / 3-way conversion supports producing the specific spec sizes target markets require. Throughput rates align — the K-JC 704 PLUS at up to 90 US tph feeds the Kompatto 5030 (capable of up to 280 US tph) without bottlenecking either piece of equipment.
Workflow Integration
Material Flow Sequence
- Material delivery to crusher feed area — demolition concrete, asphalt, brick, masonry, or natural rock arrives at the K-JC 704 PLUS feed hopper
- Pre-crushing inspection — operators remove oversized contamination, foreign objects, or unbreakable material before feeding
- Primary crushing — K-JC 704 PLUS reduces material to crushed gradation matching downstream screening requirements
- Magnetic separation — recovered rebar from reinforced concrete separates via standard hydraulic magnetic belt
- Material transfer — crushed output transfers to the Kompatto 5030 feed area via direct conveyor placement, dump truck, or wheel loader
- Vibrating scalping screening — Kompatto 5030 separates crushed material into 2 or 3 spec-sized finished product fractions simultaneously
- Finished product stockpiling — each spec-sized product stockpiles separately for customer pickup, project use, or further processing
Crusher Setting Coordination
Optimal multi-product output requires coordinating crusher closed-side setting (CSS) with screener mesh selection. Common configurations:
- Coarse CSS (larger setting): Higher throughput, broader gradation, more screener separation work, supports multiple sized products
- Tighter CSS (smaller setting): Lower throughput, narrower gradation, less screener separation work, fewer distinct sized products
Match crusher setting to target product mix and operational throughput requirements — there’s no universal optimal setting.
Material Handling Between Equipment
For continuous-production operations, the K-TC 460 portable mobile conveyor — up to 132 US tph, 25″ Chevron 3-ply belt, 25 HP Tier 4 Final, ~7,000 lb — provides direct crusher-to-screener material transfer eliminating intermediate stockpile handling. For single-stage operations, dump truck or wheel loader transfer between equipment works adequately.
Mesh Selection for Different Finished Products
Common Aggregate Spec Sizes
The Kompatto 5030’s 2-way / 3-way conversion supports multiple finished product configurations. Common spec sizes include:
- #57 stone (commonly 1″ to #4 sieve) — concrete batch plant aggregate, hot-mix asphalt aggregate
- #67 stone (commonly 3/4″ to #4 sieve) — concrete batch plants, structural backfill
- #8 stone (commonly 3/8″ to #8 sieve) — fine aggregate, leveling material
- #21A or #21B base (graded blend with fines) — road base, parking lot base, structural fill
- Decorative aggregate (varied sizes) — landscape, architectural specifications
Specifications vary by state DOT and target market — verify current requirements for project locations.
Three-Way Configuration Examples
The 3-way Kompatto 5030 configuration produces three spec-sized products simultaneously. Common configurations:
- Premium markets configuration: Coarse oversize → return to crusher; mid-size → #57 or #67 stone for premium markets; fines → #21A base for road base markets
- Multi-base configuration: Coarse → #57 stone; mid-size → blended base material; fines → #21A or finer base material
- Aggregate + base configuration: Coarse → premium concrete aggregate; mid-size → asphalt aggregate; fines → road base
Mesh Change Operations
Operations targeting different markets at different times benefit from mesh change flexibility. Mesh changes typically complete in 30-60 minutes per service operation. Operations producing single product mix continuously can run with the same mesh configuration for extended periods; operations serving variable customer demand benefit from mesh change capability.
Market Applications for Multi-Product Output
Demolition Contractors
Demolition contractors process building demolition into multiple end products simultaneously:
- RCA base material from main demolition stream — sells at $10-$25+/ton typical for road base, parking lot base, structural fill
- Premium spec aggregate (after secondary K-IC 70 processing if needed) — sells at higher pricing for concrete batch plant feedstock
- Recovered rebar from magnetic separation — $100-$300+/ton scrap metal value
- Project base material for use on the same project — eliminates aggregate purchase cost ($15-$40+/ton typical for virgin aggregate)
Recycling Operations
C&D recycling facilities producing multiple finished products from incoming demolition material capture multiple market segments:
- RCA for state DOT base material applications (non-structural where most state DOTs accept RCA)
- Aggregate for concrete batch plants (typically with K-IC 70 secondary impact crushing for cubical shape)
- Aggregate for HMA plants (RAP feedstock typically requires specific spec compliance)
- Drainage stone for septic, foundation drainage, French drain applications
- Structural fill for general construction backfill applications

Frequently Asked Questions
Why pair the K-JC 704 PLUS with the Kompatto 5030 specifically?
These are Komplet’s best-selling crusher and best-selling screener — both fit the operational sweet spot for typical contractor demolition and recycling operations. Throughput rates align (K-JC 704 PLUS at up to 90 US tph feeds the Kompatto 5030 capable of up to 280 US tph without bottlenecking either piece of equipment). Operational characteristics match (both feature wireless remote control, self-propelled tracked mobility, Tier 4 Final emissions compliance). The combination delivers proven operational capability across many operations.
Can I use a different crusher with the Kompatto 5030?
Yes — Komplet’s full jaw crusher lineup pairs with Kompatto 5030. K-JC 503, K-JC 604, and K-JC 805 all work with Kompatto 5030; throughput matching may vary based on crusher size. Operations with smaller volume needs typically pair K-JC 503 or K-JC 604 with Kompatto 221 (smaller screener). Operations with larger volume needs typically pair K-JC 805 with Kompatto 5030 or Kompatto 124. Match equipment combination to operational throughput requirements.
How many end products can the combination produce?
The Kompatto 5030’s hydraulic 2-way / 3-way conversion supports producing 2 or 3 finished product sizes simultaneously. Operations needing more product variety typically use mesh changes (30-60 minute service operation) to switch between product configurations based on market demand. Multi-pass operations (running material through screening multiple times with different mesh) can produce additional product sizes from initial output.
Do I need a secondary crusher for premium aggregate?
Depends on target market. Operations producing material for non-structural applications (road base, structural fill, drainage, parking lot base) typically don’t need secondary crushing. Operations producing premium cubical aggregate for concrete batch plants or HMA plants typically benefit from the K-IC 70 compact impact crusher as a secondary stage. The 3-stage workflow (K-JC 704 PLUS → K-IC 70 → Kompatto 5030) delivers the production volume of jaw crushing with the particle shape benefits of impact crushing.
Can Komplet America provide on-site training?
Yes — Komplet America’s authorized dealers provide operator training as part of new equipment delivery and on-request training for additional operators or seasonal refreshers.
