Project Overview
Location: Uzbekistan
Model: XLQ-160 Stationary Asphalt Mixing Plant
Rated Capacity: 160t/h & 2000kg/batch
Application Scenarios: Reconstruction and expansion of trunk highways, and urban municipal roads
As a core hub in Central Asia, Uzbekistan is vigorously upgrading its domestic highway infrastructure, with numerous trunk highway and urban road reconstruction projects underway. It features a continental temperate climate with extremely hot summers, freezing winters and huge day‑night temperature differences. The minimum winter temperature can reach ‑30℃ while summer maximum temperature may exceed 45℃. The country is rich in natural‑gas resources and it is widely used as a fuel. Local power grid voltage fluctuates. Low winter temperature imposes strict requirements on thermal insulation of bitumen tanks & pipelines and frost‑resistant performance of steel structures.
The client is a large‑scale local road‑construction contractor undertaking multiple provincial trunk‑highway projects. They required a high‑capacity stationary batch‑mix asphalt plant for large‑scale continuous production, adapted to local climate and energy conditions, to produce hot‑mix asphalt mixture complying with Central‑Asian road standards.
Core Customer Requirements
1. Stable production capacity of 160t/h with 2000kg per batch. High‑precision weighing for aggregate, bitumen and mineral powder. Capable of producing ordinary and modified asphalt mixtures to meet quality standards of Uzbekistan trunk‑highway projects.
2. Adapt to Uzbekistan's extreme temperature difference and severe winter cold. Thickened thermal‑insulation layers for bitumen tanks, delivery pipelines and hot‑aggregate bins to reduce heat loss and prevent bitumen solidification under low temperature. Anti‑freeze and anti‑corrosion treatment for steel structures to resist winter frost damage.
3. Prioritize natural‑gas fuel, equipped with dual‑fuel (natural‑gas & diesel) burner. Natural‑gas as primary fuel with diesel backup. Take advantage of abundant local natural‑gas resources to cut operating fuel cost, and avoid production halt caused by gas‑supply interruption.
4. Local power‑grid voltage fluctuates. The plant shall be fitted with voltage‑stabilizing protection. The control system supports Russian‑language interface for local operators to reduce mis‑operation risks.
5. High‑efficiency environmental dust‑removal system to comply with Uzbekistan local emission regulations. Modular stationary structure for convenient sea‑transport and on‑site erection, supporting long‑term fixed‑site continuous operation.
Customized Solution
Combined with local climate, energy and power‑grid conditions of Uzbekistan, XINGHUOTEC delivered a complete customized solution of XLQ‑160 stationary batch‑mix asphalt mixing plant, with special optimizations for severe temperature difference, natural‑gas fuel, voltage fluctuation and Russian‑language human‑machine interface.
1. Batch‑Mix Process & High‑Precision Weighing System
XLQ‑160 batch‑mix process with 2000kg per batch and rated capacity of 160t/h. Independent weighing for aggregate, bitumen and mineral powder. Weighing accuracy: ±0.5% for aggregate, ±0.25% for bitumen and mineral powder. Multiple asphalt formulas can be stored and recalled with one‑click, flexibly producing ordinary and modified asphalt mixtures to match construction proportion requirements for all‑grade highways in Uzbekistan.
2. Special Thermal‑Insulation & Anti‑Freeze Upgrade for Frigid Climate
Targeting Uzbekistan’s frigid winter and huge day‑night temperature difference, we added thickened thermal‑insulation layers for bitumen tanks, bitumen pipelines and hot‑aggregate bins. Additional thermal insulation is provided for the mixing tower and control room. Low‑temperature anti‑corrosion & anti‑freeze spraying for whole‑machine steel structures. Drainage and anti‑freeze design for equipment foundation to avoid ice‑damage caused by accumulated water in winter. Heat loss is minimized to guarantee normal production in cold seasons.
3. Dual‑Fuel Combustion System for Local Natural‑Gas Resources
Equipped with dual‑fuel burner, using natural‑gas as main fuel and diesel as backup. It takes full advantage of abundant local natural‑gas resources to greatly cut fuel operating cost. Seamless switch to diesel when natural‑gas supply is interrupted, avoiding production loss and keeping project progress unaffected by gas‑supply issues.
4. Voltage‑Stabilizing Protection & Russian‑Language PLC Control
Whole electrical system is adapted for Uzbekistan power supply, equipped with voltage‑stabilizing protection device to resist grid‑voltage fluctuation and prevent control‑system alarm shutdown. PLC touch‑screen control system supports Russian‑language interface with auto/manual dual‑modes. On‑site operator training is provided so local technicians can independently complete production control and routine maintenance, lowering operation threshold.
5. Two‑Stage Pulse Bag‑House Dust‑Removal System
Two‑stage dust‑removal system (cyclone + pulse bag‑house) effectively suppresses dust emission. Dust‑emission index complies with Uzbekistan local environmental regulations, suitable for construction sites near cities and trunk highways.
6. Modular Stationary Structure & Complete Bitumen Auxiliary System
Modular assembled stationary structure, all modules can be shipped by container for fast on‑site assembly. Matched with large‑capacity bitumen thermal‑insulation tank, thermal‑oil heating system and bitumen delivery pipelines, realizing integrated bitumen storage, constant‑temperature heating and delivery for long‑term fixed‑site production of trunk‑highway projects.
Customer Feedback
“Road infrastructure projects in Uzbekistan are large‑scale, and we have high requirements for output and quality of asphalt mixture. The XLQ-160 asphalt mixing plant fully meets production demands for our trunk-highway projects.
Winters in Uzbekistan are extremely cold. The thickened thermal-insulation of the plant performs excellently. Bitumen pipelines and tanks will not solidify even under low-temperature conditions. The dual-fuel burner makes full use of local natural-gas to control fuel cost. We can switch to diesel when gas supply is insufficient without delaying construction schedule. The Russian-language control system greatly facilitates operation by our local workers.
Precise weighing delivers asphalt mixture fully complying with Uzbekistan road-construction standards. The whole plant runs stably, and dust‑removal system meets local environmental requirements. This equipment provides reliable support for our multiple trunk-highway constructions. We will consider purchasing more XINGHUOTEC asphalt-mixing equipment of this series in future.”
