SZLH420 vs SZLH508 Feed Pellet Mill: Which Capacity Fits Your Feed Mill?
Choosing the right feed pellet mill is one of the most critical decisions for any feed mill manager. Picking an underpowered machine creates a bottleneck and inefficiency, while an oversized one wastes CAPEX and energy.
Two models dominate the medium-to-large-scale segment in global markets: the SZLH420 and the SZLH508. These workhorses from Tianyou Machinery are engineered for different production ranks, but share the same DNA of rugged gear drive reliability.
In this definitive comparison, I'll break down capacity specs, ring die geometries, real-world output, power consumption, and cost per ton—so you can decide which machine fits your operation. Let's dive in.
Working Principle & Technical Design
Both models are horizontal ring die pellet mills with gear drive transmission, operating on the same core principle: agricultural raw materials (maize flour, wheat bran, soybean meal, etc.) are conditioned with steam, fed into a stationary die, and extruded through holes by one or two rotating roller assemblies.
However, size changes optimal grinding and pressing power.
SZLH420 – Specifications
- Ring Die Inner Diameter: 420 mm
- Die Working Width: 200 mm (typical base; can be varied)
- Main Motor Power: 110–160 kW (common specs 132 kW, more often employed with 250 HP diesel analog option)
- Num Pressure Rollers: Two (two rollers inside diam loop)
- Production Hopper Pass Steel Conditioning System via feeder and conditioner
- Man Power Shift Sourcing Switch Device options available–Single Feeder Unit
- Equips with Constant Inching Magnet
SZLH508 – Ramification Dimensions
- Blade Gate Press & Holes Engine Dimensions 8: 520–620 kW Main Huddle Power--We're starting earlier ; but diesel-to-JD-A simple case outputs/Off-line capacity scaling list
- Die ID: 508 mm diameter press rigid tough work heat to make pellets
- Correspond Working Widening
