Parameter Analysis & Supplement:
The specifications in the table above are designed to provide a clear performance benchmark. Below is a further explanation of their practical implications for your operation.
Motor Power & Capacity: The scaling of motor power (30 kW to 55 kW) directly correlates with the increase in chamber volume and potential throughput. A larger chamber requires higher torque to process a greater volume of material effectively. The stated capacity is a benchmark for clean, high-density materials with a large screen. Actual throughput will vary based on material type, infeed consistency, and final particle size requirements.
Crushing Chamber Opening: This dimension (600mm to 1000mm) is a critical factor for operational efficiency as it dictates the maximum acceptable size of the input material. A wider opening reduces the need for extensive pre-cutting or pre-shredding of bulky items like drums or baled films, directly translating into labor savings and a more streamlined workflow.
Knife Configuration & Material: The machine utilizes a V-type configuration with 10 rotating knives and 4 stationary knives to maximize the number of cutting points per revolution. The standard knife material, 60Si2Mn, is a high-toughness spring steel selected for its excellent impact resistance, making it resilient to damage from minor contaminants. For applications involving highly abrasive materials such as glass-filled plastics, an optional upgrade to D2 (SKD-11) tool steel is available to prioritize wear resistance over impact toughness.

Frequently Asked Questions
Most frequently asked questions by customers who purchased Shuliy plastic crusher.The TCO for the SLSP-800 is designed to be highly competitive. Your main operational costs will be:
- Energy: The 45 kW motor is efficiently managed by our V-type rotor, which reduces power consumption by 15-20% compared to flat-rotor designs.
- Wear Parts: This is primarily knives and screens. The standard 60Si2Mn knives have a service life of 500-800 hours per edge before needing to be resharpened. Budgeting for one resharpening service and one spare set of knives per year is a safe financial forecast for single-shift operations.
- Labor: The crushing machine is designed for low-maintenance operation, requiring only routine checks and blade adjustments, not a dedicated full-time operator. Due to its energy efficiency and the longevity of its wear parts, the SLSP-800 offers a significantly lower TCO over its lifespan compared to cheaper, less efficient alternatives.
Absolutely. This flexibility is a core reason why business owners choose the SLSP-800. The machine is fully engineered for this dual-purpose role. The switch is a straightforward mechanical adjustment:
- Adjust the knife clearance to a tighter setting (~0.5mm) for film.
- Swap the screen from a large-aperture one (e.g., ø50mm) to a smaller one (e.g., ø26mm). The only additional investment required is one spare screen with the desired aperture for film. The SLSP-800’s built-in wet crushing capability is then ready to use, with no further machine modifications needed. Your initial investment is future-proofed.
We understand that downtime directly impacts your revenue. That is why we maintain a ready stock of all standard wear parts for the SLSP-800, including knives and screens. Upon order confirmation, we can dispatch these parts via international air freight within 48 hours. To completely eliminate the risk of waiting, we strongly advise our clients to purchase one spare set of knives and their most-used spare screen along with the initial machine order. This small upfront investment acts as your best insurance policy against unscheduled downtime.
This is a crucial system-level question. To ensure smooth, continuous operation and account for fluctuations in material density, we recommend that both your upstream and downstream equipment be rated for at least 20% higher capacity than the crusher’s target output. For the SLSP-800, your feeding conveyor and washing line should ideally have a capacity of at least 1200 kg/h. This ensures the crusher is never starved for material and the downstream line is never overwhelmed, maximizing the efficiency of your entire plant. We can supply a fully integrated and perfectly matched line to guarantee this performance.
The answer lies in Optimized Return on Investment (ROI).
- Versus cheaper alternatives: The SLSP-800 delivers long-term value. While the initial price may be higher, its superior build quality, energy-efficient design, and longer-lasting wear parts result in a significantly lower Total Cost of Ownership. You are investing in reliability and lower operational costs per ton of processed material.
- Versus premium European brands: The SLSP-800 offers an exceptional performance-to-price ratio. It delivers 80-90% of the performance and reliability of high-end European machines at a fraction of the cost. With a proven track record in over 50 countries, you are investing in globally validated technology without the excessive brand premium, leading to a much faster ROI for your business.
Yes, absolutely. The SLSP-800 is engineered for this exact application. Its 45 kW motor provides the high torque necessary to crush thick-walled HDPE drums and barrels. The V-type rotor design delivers a powerful, focused cutting force that prevents material from simply bouncing in the chamber. When used as an HDPE Milk Bottle Granulator or for barrels, we recommend a ø50mm screen, which ensures a high throughput of 800-1000 kg/h while producing uniform, easily washable flakes.
This is a valid concern, as rigid PVC can be abrasive. The SLSP-800 is an excellent PVC Pipe Grinder due to its robust construction. For standard use, our tough 60Si2Mn steel blades perform well. However, for continuous, heavy-duty rigid PVC recycling, we highly recommend the optional D2 (SKD-11) steel blade upgrade. This hardened tool steel offers superior wear resistance, significantly extending the service life and reducing your long-term operational costs when processing abrasive materials.
Yes, this is a major efficiency advantage of the SLSP-800. Its 800mm wide crushing chamber opening is specifically designed to handle bulky items. You can directly feed most broken crates and pallet fragments into the machine. This makes it an ideal Plastic Crate Crusher, drastically reducing the labor costs associated with pre-processing and creating a much safer, more streamlined workflow for your team.
The SLSP-800 solves the challenges of Agricultural Film Granulator applications through three key features:
- Scissor-Cut Action: We set the blade clearance to a tight ~0.5mm, which, combined with the V-type rotor, creates a clean shearing cut that prevents film from stretching and wrapping.
- Wet Crushing: By injecting water into the chamber, the film becomes heavier, allowing it to feed into the rotor consistently instead of floating.
- Pre-Washing: The water simultaneously provides a preliminary wash, removing dirt and dust early in the process, which improves the quality of your final product.
This is a common problem with low-density materials. The SLSP-800 overcomes this with the aggressive geometry of its V-type rotor. The angled blades effectively “grab” and pull the light bubble wrap material down into the cutting zone, preventing it from just bouncing on top. For maximum efficiency, we again recommend using the wet crushing feature. The water helps to collapse the air pockets in the bubble wrap, increasing its bulk density and making the granulation process much faster and more consistent.
