Introduction to the 60–80 TPH Portable Stone Crushing Plant (Jaw + Cone Crusher Combination)

1. Core Equipment Overview

These portable rock crushers are designed for medium-scale stone production, with a steady working capacity of 60 to 80 tons per hour.

The whole set is a complete two-stage crushing and screening system. It includes a portable jaw crushing station for feeding and primary crushing, plus a portable cone crushing station for secondary crushing and final screening. This matched set of portable rock crushers works perfectly for most common stone processing projects.

The jaw station handles big raw stones and breaks them down into medium-size materials. Then the cone station further crushes and screens the stones into clean, finished aggregates.

- Portable Jaw Crushing Station (Primary Crushing)

It is fitted with a standard PE 500×750 jaw crusher. The feed opening size is 500×750mm, and it can take raw stones up to 420mm in size. This machine breaks large rock blocks into medium materials between 50mm and 100mm. It is the first and most important crushing unit of these portable rock crushers.

- Portable Cone Crushing Station (Secondary Crushing & Screening)

This unit uses a PYSB 0917 spring cone crusher with a 900mm crushing cone. It comes with a built-in vibrating screen. After receiving coarse materials from the jaw crusher, it finely crushes and screens the stones into different finished sizes. This completes the full production flow of the portable rock crushers.

All key parts — feeder, crusher, screen, conveyor belts and control cabinet — are installed on a mobile tire chassis. No concrete foundation is needed. You can move and set up these portable rock crushers very fast on any job site. Normally, the average output ranges from 70 to 90 tons per hour. They work well for granite, basalt, limestone, river pebbles and many other kinds of rock.

2. Feed Size Standard

Max feeding size: 420mm

The PE 500×750 jaw crusher supports a maximum input size of 420mm. During daily operation, we suggest keeping the feed size under 420mm. This way, the machine feeds smoothly and avoids blockage. Because of this stable feeding performance, these portable rock crushers are ideal for mining site rocks and large natural stones.

3. Production Output Data

- Standard hourly output: 60–80 tons of finished aggregate

- Average stable output: around 70 tons per hour (for medium-hard stone like limestone, with even feeding)

- Output range difference:

Hard rock such as granite: 60–80 tons/h

Soft rock such as limestone: 70–90 tons/h

The actual output of these portable rock crushers depends on stone hardness, feeding speed and finished size requirements.

4. Finished Stone Sizes (Standard International Sizes)

The PYSB 0917 cone crusher has adjustable discharge gaps from 13mm to 38mm. Together with the vibrating screen, these portable rock crushers can produce four common standard aggregate sizes for most construction projects:

1. 0–5mm (fine sand)

Used for concrete filling, mortar mixing, road base leveling and brick making.

2. 5–10mm (small aggregate)

Widely used for precast parts, road surface layers, permeable concrete and wall plastering.

3. 10–20mm (medium aggregate)

This is the most popular size. Perfect for commercial concrete, building structures, bridge bases and road stable layers.

4. 20–31.5mm (large aggregate)

Suitable for dams, heavy road bases, airport roads, high-grade concrete and large foundation projects.

5. Main Application Areas

These portable rock crushers are very versatile and fit many different job sites:

1. Mining and Quarry Work

Crush granite, limestone, basalt and other ores to make construction aggregates.

2. Road and Transport Projects

Supply qualified stone for highways, railways, bridge foundations and road paving.

3. Building Construction

Produce standard concrete stone for residential buildings, office buildings and factory plants.

4. Water Conservancy Projects

Make high-quality aggregate for dams, river embankments and irrigation works.

5. Construction Waste Recycling

Crush old concrete blocks and bricks into reusable recycled stone.

6. On-site Mobile Crushing

You can run these portable rock crushers directly in mountains, mining zones or construction sites. This saves a lot of cost on stone transportation.

7. Key Advantages of This Plant

Compared with fixed crushing lines, these portable rock crushers have many practical benefits for contractors and mine owners:

1. Easy to move and fast to set up

The wheeled trailer chassis allows easy transportation between sites. No fixed foundation is required. You can start production right after arrival.

2. Stable and reliable output

The matching combination of PE500×750 jaw crusher and 0917 cone crusher is a very mature design. With closed-loop crushing and screening, these portable rock crushers keep steady hourly output for long-term work.

3. Great stone shape quality

The cone crusher uses layer crushing technology. The finished stones are mostly cubic, with very few flat or needle-shaped particles. The quality meets high-standard engineering requirements.

4. Flexible finished size adjustment

With hydraulic gap adjustment, you can easily switch between the four common stone sizes to match different project needs.

5. Long service life and low wear cost

The jaw plates and cone liners are made of high manganese steel. They are strong, wear-resistant and suitable for crushing hard rock. These parts ensure stable performance for the portable rock crushers.

6. Dual power support

The plant works with both city electricity and diesel generators. It can run normally even in remote areas without stable power supply. This makes the portable rock crushers highly adaptable.

7. Simple intelligent control

Equipped with centralized control system. It supports one-key start and stop, overload protection and fault warning. Operation is safe, simple and easy to manage.

8. Working Principle

Jaw Crushing Station (First Stage Crushing)

This machine works by extrusion movement:

The motor drives the eccentric shaft, making the movable jaw move back and forth. When the movable jaw closes to the fixed jaw, big stones are squeezed and broken. When the jaw opens again, the broken stones fall down by gravity. The output material size is kept between 50–100mm, then sent to the cone crusher for further processing.

Cone Crushing & Screening Station (Second Stage)

The cone crusher uses layer crushing:

After coarse stones enter the crushing chamber, the motor drives the eccentric sleeve, making the movable cone swing continuously. The stones are squeezed, bent and crushed layer by layer.

Qualified small stones fall out and go to the vibrating screen for classification. After screening, you get four clean finished sizes. Any oversize stones will be sent back to the cone crusher for re-crushing, so the portable rock crushers achieve full closed-loop production.

9. Main Wear Parts
