Yes. The slurry pump speed (where a VFD is fitted) and the cyclone feed pressure together control the cut size and underflow density. Raising pump pressure recovers finer material; lowering it reduces fine-sand output and increases clarified overflow clarity. The wheel-washer weir height adjusts independently to set the coarse product's fines content. All adjustments are made while the machine is running.

The dewatering screen discharges clarified overflow water back to the wash-water tank for recirculation, and discharges a small volume of slurry - carrying sub-75 µm ultrafines - to the settling pond. The hydrocyclone overflow (very fine clay and water) also routes to the pond. For sites with tight discharge consent limits, a flocculation dosing system on the pond feed is recommended to accelerate settlement.

A separate wheel washer and fine-sand recovery unit require independent civil foundations, inter-unit pipework and pumping, separate electrical panels, and a qualified installer to align and commission two machines. The XSHJX ships as a pre-assembled, pre-piped, pre-wired unit on a single frame - civil works are limited to a flat concrete pad and anchor bolts, and commissioning typically completes in one to two days. For plants where downtime and site complexity are key concerns, the integrated machine is the standard recommendation.

Remote commissioning support via video call is included at no charge. On-site engineer dispatch is available as an optional paid service - lead time and cost depend on location. Please discuss before purchase.

At standard weir setting, the LSX / 2LSX series loses approximately 8–18% of the sub-0.15 mm fraction. For applications where fine-sand recovery is commercially important, pair the screw washer with a fine-sand recovery system (hydrocyclone bank plus dewatering screen) on the overflow stream to capture and dewater the fines before they enter the settling pond.

A screw washer uses a rotating helical flight to convey, agitate, and drain sand along an inclined tub. It handles higher feed rates and is better suited to feeds with high clay or silt content requiring extended agitation. A wheel washer uses a large-diameter impeller with lifting buckets and is gentler on the product, with slightly lower fines loss. For coarse-sand or light washing duties at moderate capacity, a wheel washer may be preferred; for high-capacity or high-contamination feeds, the screw washer is the standard choice.

Single-screw LSX models use one helical flight in a single tub, covering 15–120 t/h. Twin-screw 2LSX models place two parallel screws in a shared tub, roughly doubling throughput to 60–280 t/h for the same footprint length. Both share the same mechanical architecture and spare parts - only the tub width and drive count differ, simplifying inventory for plants that run both types.

MB and MBZ models sharing the same cylinder dimensions (e.g., MB 2436 and MBZ 2436) have identical shell diameter and length but differ in rod charge mass, installed motor power, and resulting capacity range. The MBZ variant carries a higher rod charge and more drive power, increasing throughput capacity by roughly 75–115% over the MB variant at the same cylinder size. Selecting MBZ over MB allows a capacity increase without changing the mill's footprint, foundation, or building envelope - useful for plant expansions on constrained sites.
