200-300 TPH Limestone Crushing Plant in Uzbekistan

Liming Heavy Industry successfully designed, manufactured, and commissioned a 200-300 tons per hour (TPH) limestone crushing plant for a key aggregate supplier in Uzbekistan. By utilizing the European-standard PEW860 Jaw Crusher and the highly efficient PFW1315III Impact Crusher, the client achieved a 15% reduction in maintenance downtime and produced premium, cubical-shaped aggregates perfectly suited for high-grade concrete production.

Client Profile & Project Overview

The client is a prominent building materials manufacturer and aggregate supplier based in Uzbekistan. With the rapid growth of local infrastructure projects, the client needed to upgrade their existing facilities to meet the surging demand for high-quality building materials.

• Project Location: Uzbekistan
• Raw Material: Limestone (Medium Hardness)
• Capacity Demand: 200-300 TPH (Tons Per Hour)
• Final Product Sizes: 0-5mm, 5-10mm, 10-20mm (Customizable based on screen mesh), 5×20, 20×40, 40×70, 70×120
• Application: High-grade concrete batching plants and highway construction.

The Core Challenges

During the initial consultation, the client highlighted several operational and environmental challenges:

1. Harsh Working Environment: The equipment needed to withstand the fluctuating and sometimes extreme temperatures of the Central Asian climate.
2. High Shape Requirement: The local market demands excellent cubical particle shape with minimal flakiness for highway construction.
3. Operational Efficiency: The client wanted a highly automated system to reduce labor costs and lower maintenance downtime.

Liming Heavy Industry’s Custom Solution

Based on the limestone’s characteristics and the 200-300 TPH capacity requirement, the senior engineering team at Liming Heavy Industry proposed a two-stage crushing solution. This configuration balances high throughput with excellent final product shape.

Detailed Equipment Configuration

• Primary Crushing: PEW860 Jaw Crusher
  Role & Advantage: Acting as the primary crusher, the PEW series European Jaw Crusher handles large limestone boulders with ease. Its advanced “V-shaped” crushing cavity and robust hydraulic wedge adjustment system ensure a larger feed size, higher crushing ratio, and faster, safer discharge opening adjustments compared to traditional models.
• Secondary Crushing: PFW1315III Impact Crusher
  Role & Advantage: Limestone is highly suited for impact crushing. The PFW series utilizes a heavy-duty rotor and a unique hydraulic top-opening device. This machine not only processes the material efficiently but also acts as a shaping tool, ensuring the final aggregates are perfectly cubical and free of tension cracks.
• Feeding System: GZD1100×4200 Vibrating Feeder
  Role & Advantage: Provides continuous and uniform feeding of raw limestone into the jaw crusher while pre-screening out dirt and fine debris, protecting the primary crusher from unnecessary wear.
• Screening System: 3YZS2160 Vibrating Screen
  Role & Advantage: A three-deck screen that accurately grades the crushed limestone into the required specific sizes (0-5mm, 5-10mm, 10-20mm). It operates with high vibration intensity, preventing mesh clogging and ensuring high screening efficiency.

Technical Highlights of the Production Line

This specifically designed limestone crushing line incorporates several technical advantages:

• Intelligent Hydraulic Control: Both the PEW Jaw Crusher and PFW Impact Crusher feature hydraulic systems that allow for one-button operation for maintenance and cavity clearing, drastically reducing manual labor.
• Optimized Plant Layout: The compact design minimizes the footprint and shortens the conveyor belt lengths, reducing initial investment and daily power consumption.
• Eco-Friendly Operations: Equipped with advanced dry dust collectors and noise reduction technology, the plant meets strict environmental regulations.

Project Results & Customer Testimonial

Since the official commissioning of the plant, the production line has run stably, consistently exceeding the 200 TPH target and often reaching peak capacities of 300 TPH during optimal conditions. The high-quality aggregate produced has allowed the client to secure two major government highway contracts.

Client Feedback
