YMC120 - Tracked Mobile Jaw Crusher Solution
The YMC120 crawler jaw crusher is a track-mounted primary crushing station with a published capacity band of 300–520 t/h, built around a 160 kW C120 jaw crusher and a GZD1242 vibrating feeder. For a 200 tph river pebble target in the Philippines, the YMC120 works as the primary stage ahead of a tracked cone crusher and screen, producing 0–40 mm aggregate from a hard, siliceous feed.
What Materials Can the YMC120 Crawler Jaw Crusher Process?
The YMC120 crawler jaw crusher is configured for hard, abrasive rock — river pebble, basalt, granite, andesite and quartz-bearing gravel — across the 0–950 mm feed figure published on Baichy's crawler mobile crusher plant page. The C120 chamber reduces rock by compression, so a harder feed raises the required crushing force but does not change the configuration of the station.
1. River Pebble and Other Siliceous Gravel
river stone crushing
River pebble is a naturally rounded, siliceous gravel. Its abrasiveness, not its compressive strength, sets the wear rate of the jaw plates and the practical cost per ton of finished aggregate.
Because abrasiveness varies from deposit to deposit, Baichy asks for the Los Angeles abrasion loss of the deposit (ASTM C131 or ASTM C535) and its compressive strength before naming a jaw plate grade. Without those two measured numbers, any wear-cost estimate for a river pebble duty is an assumption rather than a calculation.
Baichy quotes manganese jaw plates as the standard wear part for the C-series chamber and steps up to an alloy grade when the measured abrasion loss of the deposit is high.
2. What Feed Size Should a River Pebble Plant Accept?
As Baichy's standard feed-control rule, river pebble feed to the YMC120 is held at or below 80% of the jaw's feed opening width, measured on the actual top size that leaves the loader or excavator bucket rather than on the deposit's nominal gradation. Oversize boulders that bridge the feed opening are the most common cause of a crawler jaw station running below its quoted output.
The absolute maximum feed size for the C120 chamber is marked in the specification table below: Baichy's crawler mobile crusher plant page publishes a 0–950 mm feed figure at page level, but it does not publish the model-level feed opening for the C120. Baichy confirms the model figures in writing with the quotation.

How Do You Reach 200 tph of River Pebble with a YMC120?
A 200 tph target sits below the YMC120's published 300–520 t/h band, which means the plant is sized by the product spec and the closed-side setting rather than by the maximum throw of the jaw. Three decisions set the figure: the closed-side setting that delivers your top size, the top size of the feed going in, and whether a secondary stage closes the circuit.
Start From the Product Size, Not the Capacity
Rated capacity on a specification sheet is measured at a defined closed-side setting. Tightening that setting to reach a smaller top size reduces throughput, which is why one YMC120 can legitimately be quoted anywhere across a 300–520 t/h band.
Set the finished product first — 0–40 mm for base aggregate, or 0–100 mm where the jaw output feeds the next stage — then set the closed-side setting that produces it. The YMC120 changes that setting hydraulically from the control panel without stopping the plant, so the same station can be re-tuned between campaigns.
Which Crawler Jaw Model Matches Which Duty
Baichy publishes five crawler jaw models, and the published band narrows the choice faster than any other single figure.
| Target output (river pebble) | Recommended crawler jaw | Published capacity band |
|---|---|---|
| 80–125 t/h | YMC80 (C80, 55 kW) | 80–125 t/h |
| 100–250 t/h | YMC96 (C96, 90 kW) | 100–250 t/h |
| 160–360 t/h | YMC106 (C106, 132 kW) | 160–360 t/h |
| 200–450 t/h | YMC116 (C116, 132 kW) | 200–450 t/h |
| 300–520 t/h | YMC120 (C120, 160 kW) | 300–520 t/h |
When the YMC116 Is the Better Match
If 200 tph is a firm, year-round requirement rather than a nominal plant rating, the YMC116 crawler jaw crusher — published at 200–450 t/h with a 132 kW C116 chamber — matches the duty more closely than the YMC120. Baichy sizes the primary stage against the customer's measured throughput and feed gradation, not against the largest unit in the range.
For a river pebble duty of this size, a 200 tph working point inside a 300–520 t/h band leaves capacity that is paid for but never used; the same money spent on a correctly sized primary plus a secondary cone usually buys more finished tonnage.
Closing the Circuit with a Tracked Cone and Screen
River pebble is hard enough that a jaw crusher alone cannot deliver a specification-sized aggregate in one pass. The primary stage normally feeds a tracked cone crusher, which feeds a tracked screen, with oversize returned to the cone as circulating load.
A jaw plus cone plus screen train holds the finished size inside 0–40 mm and lets the operator change the blend by changing screen decks rather than by re-setting the jaw.

Running the YMC120 in Philippine Conditions
Two local conditions decide the electrical and chassis specification for a Philippine river pebble site: a 60 Hz national grid, and a wet season that turns quarry floors into saturated ground.
Power Supply: 230/400 V, 60 Hz
Mains electricity by country (Wikipedia) lists the Philippine supply as 230/400 V, 60 Hz, so a 50 Hz motor configuration runs off its design speed when wired directly to that grid. Confirm the measured voltage and frequency with the local utility before motor windings are specified, because published country tables and the actual service drop can differ.
The YMC120's diesel-electric drive removes the dependency: the onboard generator sets the frequency, and the station runs to the same specification whether or not a grid connection exists. For sites that will connect to the grid, Baichy matches motor windings and control voltage to the measured supply at the site.
This matters for river-bar operations in particular. Sand and gravel deposits along Philippine rivers are often worked far from a service drop, and the 403 kW prime / 448 kW standby generator setup A carries the crushing, conveying and dust suppression loads without a line connection.
Wet Season, Soft Ground and Dust
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) records an average of about 20 tropical cyclones entering the Philippine Area of Responsibility each year, with roughly 8 or 9 of them crossing the country. A tracked chassis keeps the YMC120 working while wheeled equipment is immobilised by saturated ground, and the heavy-duty undercarriage handles the rutted haul roads that follow heavy rain.
Dry fog dust suppression is an optional line item on the YMC120. It is normally specified where a river pebble site operates close to a residential area or a watercourse, which is common on Philippine river-bar workings.
FAQ: YMC120 Crawler Jaw Crusher
1. What is the rated capacity of the YMC120 crawler jaw crusher?
The YMC120 crawler jaw crusher is published at 300–520 t/h, and the working figure is set by the closed-side setting, the feed size and the material. For a hard river pebble feed Baichy quotes below the top of that band, after confirming measured feed gradation and target product size.
2. Does the YMC120 crawler jaw crusher need a concrete foundation?
No. The YMC120 is track-mounted and self-propelled, so it is walked into position, levelled, and put into production without poured foundations or civil works. Its transport envelope is 15,500 mm long, 3,200 mm wide and 3,700 mm high, which sets the low-bed trailer and road permit requirement for delivery to a Philippine site.
3. Can a YMC120 process river pebble at 200 tph?
Yes, as a primary stage, provided the 200 tph figure is set against a defined product size. The YMC120's published band is 300–520 t/h, so a 200 tph river pebble duty runs at a tightened closed-side setting. Where 200 tph is a firm year-round requirement, Baichy usually quotes the YMC116 (200–450 t/h) instead.
4. What is the maximum feed size for the YMC120?
Baichy's crawler mobile crusher plant page publishes a 0–950 mm feed figure. The model-level feed opening and maximum feed size for the C120 chamber are not published on the product page and are marked [待确认] in the specification table above. Baichy confirms both values in writing with the quotation.
5. What does a YMC120 crawler jaw crusher cost?
Baichy prices the YMC120 configuration by configuration rather than publishing a list price, because the generator setup, iron remover, dust suppression package, belt lengths and jaw plate grade each move the figure. Send the material type, maximum feed size in mm, target capacity in t/h and target product sizes to receive a quotation.
