Modular VSI sand production
The SC-J85D is the same SK2400 rotor on a skid: 100 mm feed, 80–260 t/h, 250 kW, 33.4 t complete. It is the sand plant for a fixed batching yard or quarry that has power and a foundation, where a crawler chassis would be paid for and never used.
A short walk-around filmed on a customer site — feeding, crushing and discharge, so you can see how the machine actually runs before you shortlist it.

Turns surplus 5–20 mm into sand instead of selling it cheap.
Drops into an existing line between screen and stockpile.
A fixed sand line is usually bolted to a concrete plant: the sand goes into the mixer, so the machine never travels. On that site the modular frame does everything the tracked version does at 4.4 t less, with no undercarriage to grease and no diesel to deliver. Installation is a foundation, a level, and a cable.
It also suits quarry operators who want to convert surplus 5–20 mm chip into sand rather than sell it at chip prices. Because the frame accepts a feed conveyor and a discharge belt directly, the unit can be dropped into an existing plant between the secondary screen and the stockpile, with no re-permitting of the site layout.
The rotor accelerates feed to a high peripheral speed and throws it through the discharge ports into a crushing chamber. Stone breaks against stone in rock-on-rock configuration, or against anvils in rock-on-steel; in both cases the dominant forces are impact and attrition rather than compression, which is what rounds the particle and produces fines without flattening the grain.
Fineness is controlled by rotor speed and by how much material is cascaded around the rotor instead of through it. Running on mains power keeps that speed constant, so the fineness modulus stays where it was set, lant loses speed as load rises and the sand drifts coarser through the shift, which shows up as inconsistent concrete workability downstream.

33.4 t against 37.8 t: no crawler chassis and no 100 kW diesel engine. The SK2400 rotor, 100 mm feed, 80–260 t/h and 279.4 kW installed are identical, so the sand is the same - only the way the plant arrives on site changes.
Between the secondary screen and the stockpile. The frame accepts a feed conveyor and a discharge belt directly, so a quarry can turn surplus 5–20 mm chip into sand without new civils or a re-permitted site layout.
Impact models are the standard choice for C&D recycling, typically with magnetic separation ahead of the chamber - the Thai recycling cases show the full setup. VSI units are shaping and sand machines: they belong after the demolition stream has already been cleaned and crushed.
Standard build is 20 working days after deposit, before inland transport and sea freight; custom configurations are scheduled at drawing confirmation. On contractor duty the bottleneck is usually wear parts, not the machine, so blow bars and rotors are quoted with the plant and air-freighted in 3-7 days when stock runs low. Body warranty runs 18 months from commissioning or 3,000 operating hours, whichever comes first.
