Mobile sand making solution
The SC-85D is a tracked VSI: 100 mm feed, 80–260 t/h, a 250 kW SK2400 rotor on a 37.8 t chassis. It does the one job a cone cannot: crushed stone into sand with a cubical shape and a controlled fines curve, on site, without a separate sand-washing plant behind it.

Natural sand is either unavailable, restricted, or priced like a specialty product in most of the markets we sell into. Manufactured sand fills that gap only if the shape and the grading are right: flat, elongated particles raise the water demand of concrete and fail the sand equivalent test. A VSI fixes both, because it breaks the stone by throwing it against other stone rather than squeezing it.
The crawler chassis matters for the same reason it matters on a jaw: sand is consumed at the pour, not at the quarry. Batching plants, precast yards and road contracts all need sand at a location that changes. A tracked unit can sit beside the batching plant and produce to demand, which removes the haul and the stockpile that a fixed sand line would need.
Rock drops into a spinning rotor and is accelerated to high speed before being thrown out through ports in the rotor wall. What it hits depends on the chamber: in rock-on-rock mode it lands on a curtain of falling stone, so the breakage is stone against stone; in rock-on-steel mode it strikes anvils. Both reduce the particle and knock off its corners, which is why the product comes out cubical rather than slabby.
The rotor speed and the cascade feed (the share of material bypassing the rotor and dropping straight into the chamber) set the fineness modulus. More cascade gives a coarser sand and lower wear per tonne; more rotor feed gives a finer product and higher chrome consumption. That single adjustment is what lets one machine serve a 0–5 mm concrete sand and a finer plaster sand.

The four questions buyers ask first about this machine - answered from the spec sheet, the cases library and the service programme.
Rotor speed and cascade feed - the share of material that bypasses the rotor and drops into the chamber. More cascade gives coarser sand and lower wear per ton; more rotor feed gives finer sand and higher chrome consumption. One adjustment, no parts change.
Because crusher dust is flat, elongated and badly graded, which raises water demand and fails the sand equivalent test. The SK2400 rotor knocks the corners off and produces a cubical, continuously graded sand; 0–31.5 mm is the chamber range, and the screen cuts the saleable 0–5 mm out of it.
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.
