Ⅰ. What This Machine Actually Does
The Dry-type mobile screening machine S1303E is the all-electric version of the S1303: 32 tons, 180–350 tph, 57 kW main motor. Built for small-to-medium fixed yards, urban C&D sorting sites, and projects near residential areas — it runs on grid power with low noise and low operating cost.
Ⅱ. Key Selling Points
• Pure electric direct drive: without the diesel, noise drops below 75 dB — no complaints near city or residential sites, and night shifts are possible.
• Variable-frequency start of the 57 kW motor avoids transformer surge; runs on a 100 kVA+ grid, so small yards don\’t need capacity upgrades.
• Low operating cost: electricity saves 150–200 RMB/hour vs diesel; at 2,000 hours/year that\’s 300,000–400,000 RMB saved — the price premium pays back within a year.
• No diesel means no oil, filter, or injector maintenance — mechanics\’ workload halves, failure rate drops, and downtime shrinks.
• Compact 32-ton design tows on one flatbed; on-site relocation is just rolling up the cable — no need to dismantle the screen box.
• Hydraulically adjustable deck angle; quick-change mesh lets two workers swap a panel in 15 minutes; optional self-cleaning polyurethane panels prevent blinding on wet feed.
• Tracked remote-control mobility climbs 30° slopes; it drives itself between sites without crane or trailer, cutting relocation time from three days to half a day.

Ⅳ. Frequently Asked Questions
Q1: Is a 100 kVA transformer enough?
Answer: The S1303E main motor is 57 kW; including the vibrator and hydraulic pump, total draw is about 70 kW. With VFD starting, a 100 kVA transformer is sufficient. Our electrician verifies on-site before contract signing.
Q2: Price difference vs the diesel S1303?
Answer: The E version is slightly cheaper than the RS (diesel) version since the engine is removed, but you supply the cable. Over the long run electricity beats diesel — at 2,000 hours/year you save over 300,000 RMB.
Q3: No diesel engine — cold winter startup?
Answer: The electric version has no diesel engine, so no winter preheat — push the button and it starts. The control cabinet includes a heater, keeping internal temperature above 5°C even at -40°C.
Ⅴ. A Real Site Story
A small ready-mix plant in Ningbo, Zhejiang, had its yard inside the factory with residential buildings 50 m away. Running a diesel screen, villagers filed three complaints a day and the environmental bureau issued two rectification notices. In 2025 they switched to the Dry-type mobile screening machine S1303E electric version; noise dropped from 92 dB to 70 dB and they passed the environmental check on the first try. The owner did the math: electricity is 8,000 RMB/month vs 30,000 RMB/month for diesel — saving 260,000 RMB/year; plus 20,000 RMB/year less in oil and filter service. The 60,000 RMB price difference paid back in three months. If your yard is fixed and near housing, the electric version is a real necessity.
